Antimicrobial activities of synthetic bismuth compounds against Clostridium difficile. (1/1505)

Clostridium difficile is a major nosocomial pathogen responsible for pseudomembranous colitis and many cases of antibiotic-associated diarrhea. Because of potential relapse of disease with current antimicrobial therapy protocols, there is a need for additional and/or alternative antimicrobial agents for the treatment of disease caused by C. difficile. We have synthesized a systematic series of 14 structurally simple bismuth compounds and assessed their biological activities against C. difficile and four other gastrointestinal species, including Helicobacter pylori. Here, we report on the activities of six compounds that exhibit antibacterial activities against C. difficile, and some of the compounds have MICs of less than 1 microgram/ml. Also tested, for comparison, were the activities of bismuth subcitrate and ranitidine bismuth citrate obtained from commercial sources. C. difficile and H. pylori were more sensitive both to the synthetic bismuth compounds and to the commercial products than were Escherichia coli, Pseudomonas aeruginosa, and Proteus mirabilis, and the last three species were markedly resistant to the commercial bismuth salts. Testing with human foreskin fibroblast cells revealed that some of the synthetic compounds were more cytotoxic than others. Killing curves for C. difficile treated with the more active compounds revealed rapid death, and electron microscopy showed that the bismuth of these compounds was rapidly incorporated by C. difficile. Energy dispersive spectroscopy X-ray microanalysis of C. difficile cells containing electron-dense material confirmed the presence of internalized bismuth. Internalized bismuth was not observed in C. difficile treated with synthetic bismuth compounds that lacked antimicrobial activity, which suggests that the uptake of the metal is required for killing activity. The nature of the carrier would seem to determine whether bismuth is transported into susceptible bacteria like C. difficile.  (+info)

How intestinal bacteria cause disease. (2/1505)

An improved understanding of how intestinal bacteria cause disease has become increasingly important because of the emergence of new enteric pathogens, increasing threats of drug resistance, and a growing awareness of their importance in malnutrition and diarrhea. Reviewed here are the varied ways that intestinal bacteria cause disease, which provide fundamental lessons about microbial pathogenesis as well as cell signaling. Following colonization, enteric pathogens may adhere to or invade the epithelium or may produce secretory exotoxins or cytotoxins. In addition, by direct or indirect effects, they may trigger secondary mediator release of cytokines that attract inflammatory cells, which release further products, such as prostaglandins or platelet-activating factor, which can also trigger secretion. An improved understanding of pathogenesis not only opens new approaches to treatment and control but may also suggest improved simple means of diagnosis and even vaccine development.  (+info)

A novel cytotoxin from Clostridium difficile serogroup F is a functional hybrid between two other large clostridial cytotoxins. (3/1505)

The large clostridial cytotoxins (LCTs) constitute a group of high molecular weight clostridial cytotoxins that inactivate cellular small GTP-binding proteins. We demonstrate that a novel LCT (TcdB-1470) from Clostridium difficile strain 1470 is a functional hybrid between "reference" TcdB-10463 and Clostridium sordellii TcsL-1522. It bound to the same specific receptor as TcdB-10463 but glucosylated the same GTP-binding proteins as TcsL-1522. All three toxins had equal enzymatic potencies but were equally cytotoxic only when microinjected. When applied extracellularly TcdB-1470 and TcdB-10463 were considerably more potent cytotoxins than TcsL-1522. The small GTP-binding protein R-Ras was identified as a target for TcdB-1470 and also for TcsL-1522 but not for TcdB-10463. R-Ras is known to control integrin-extracellular matrix interactions from inside the cell. Its glucosylation may be a major determinant for the cell rounding and detachment induced by the two R-Ras-attacking toxins. In contrast, fibroblasts treated with TcdB-10463 were arborized and remained attached, with phosphotyrosine containing structures located at the cell-to-cell contacts and beta3-integrin remaining at the tips of cellular protrusions. These components were absent from cells treated with the R-Ras-inactivating toxins. The novel hybrid toxin will broaden the utility of the LCTs for clarifying the functions of several small GTPases, now including also R-Ras.  (+info)

Immunogenicity of a Salmonella typhimurium aroA aroD vaccine expressing a nontoxic domain of Clostridium difficile toxin A. (4/1505)

The C-terminal repeat domain of Clostridium difficile toxin A harbors toxin-neutralizing epitopes and is considered to be a candidate component of a vaccine against C. difficile-associated disease (CDAD). Fourteen of the 38 C-terminal toxin A repeats (14CDTA) were cloned into pTECH-1 in frame with the immunogenic fragment C of tetanus toxin (TETC) to generate plasmid p56TETC. Expression of the TETC-14CDTA fusion protein was driven from the anaerobically inducible nirB promoter within attenuated Salmonella typhimurium BRD509 (aroA aroD). The TETC-14CDTA fusion protein was purified and shown to bind to known toxin A receptors found on the surface of rabbit erythrocytes. Intranasal (i.n.) and intragastric (i.g.) immunization with 10(7) and 10(10) CFU, respectively, of BRD509(p56TETC) generated significant (P < 0.05) anti-toxin A serum responses after a single dose. Antibody titers were elevated following a boosting dose with either live vaccine or a subcutaneous injection of 0.5 microgram of purified 14CDTA protein. Importantly, serum from mice immunized with BRD509(p56TETC) neutralized toxin A cytotoxicity. Both i.n. and i.g. immunizations also generated toxin A-specific immunoglobulin A on the pulmonary and intestinal mucosa, respectively. Intranasal vaccination induced consistently higher serum and mucosal anti-toxin A antibody responses. Significant anti-tetanus toxoid serum and mucosal antibodies were also generated by both immunization routes. The availability of live attenuated Salmonella typhi for human use may allow the development of a multivalent mucosal vaccine against CDAD, tetanus, and typhoid.  (+info)

Factors associated with prolonged symptoms and severe disease due to Clostridium difficile. (5/1505)

OBJECTIVE: toxigenic Clostridium difficile is responsible for a spectrum of disease severity ranging from mild diarrhoea to fulminant colitis. This study attempts to determine the proportion of patients in each category of severity and evaluate the risk factors for a more prolonged and complicated course. DESIGN: prospective cohort study. SETTING: university teaching hospital. SUBJECTS: all patients with symptomatic C. difficile infection during 4 months of an outbreak (January-April 1995); n=73; median age 74 years (range 17-91). MEASUREMENTS: incidence of C. difficile-associated disease (CDAD); severity of disease; percentage of patients in each category of severity; risk factors for severe disease/prolonged symptoms (univariate and multivariable analyses). RESULTS: the incidence of CDAD was 0.93%. Of the cases identified, 18 (24.7%) had mild, self-limiting disease; 26 (35.6%) had moderately severe disease; 23 (31.5%) had prolonged symptoms and six (8.2%) had a complicated course. Although CDAD was more common in older patients (P < 0.001), increasing age was not a risk factor for severity. Significant risk factors for severe CDAD included low Barthel and abbreviated mental test scores (P < 0.01, P < 0.001 respectively) and recent endoscopy (P=0.03). Logistic regression analysis revealed the following independent predictors of severe CDAD: endoscopy [odds ratios (OR) 4.0, P=0.03] and cognitive impairment (OR 11.0, P < 0.01). A trend towards significance was noted for nasogastric tube insertion (OR 3.1, P=0.08). Complications of infection included dehydration, malnutrition and faecal incontinence (which was statistically significantly associated with more severe disease; P < 0.01). CONCLUSION: risk factors for severity of CDAD include functional disability, cognitive impairment, and recent endoscopy. Anticipation of severe CDAD may limit morbidity and mortality.  (+info)

Incidence and outcome of Clostridium difficile infection following autologous peripheral blood stem cell transplantation. (6/1505)

A retrospective evaluation of 200 consecutive recipients of autologous peripheral blood stem cell transplantation (PBSCT) was conducted to ascertain the incidence and outcome of infection with Clostridium difficile. The diagnosis was confirmed in 14 patients with diarrhea (15 episodes) at a median of 33 days after stem cell infusion. Five patients were neutropenic at the time of diagnosis. Every individual had adverse known risk factors such as recent or current use of antibiotic, corticosteroid and antiviral therapy, recent administration of myeloablative chemotherapy and numerous, prolonged periods of hospitalization. Diarrhea, frequently hemorrhagic, was the most common presenting feature along with fever, abdominal cramps and abdominal distention. Diagnosis was established by the stool-cytotoxin test. Response to standard treatment with oral vancomycin or metronidazole was prompt despite the presence of several adverse prognostic features in these patients. There was only one instance of relapse which was also treated successfully. Several transplant-related variables such as age, sex, underlying malignancy, myelo-ablative regimen, duration of neutropenia, and prophylactic use of oral ampicillin underwent statistical analysis but failed to be predictive of C. difficile infection in such a setting. Finally, C. difficile is not uncommon after autologous PBSCT and must be included in the differential diagnosis in any such patient with diarrhea.  (+info)

Suppression of toxin production in Clostridium difficile VPI 10463 by amino acids. (7/1505)

The impact of various growth conditions on the expression of toxins and other proteins by Clostridium difficile VPI 10463 was studied. During non-starved conditions, the rate of toxin synthesis paralleled that of total protein during both exponential growth and stationary phase, and in both defined and complex media. Biotin limitation reduced growth rate and bulk protein synthesis, whereas toxin expression continued, leading to a 50- to 200-fold increase in intracellular toxin levels. Concomitantly, several 22 kDa proteins were up-regulated as revealed by two-dimensional PAGE analysis. The toxin yield was 30-fold higher in peptone yeast extract (PY) than in PY containing glucose (PYG). By contrast, glucose limitation reduced toxin yields by 20- to 100-fold in defined media. By elevating the buffering capacity and bicarbonate concentration, toxin yields were increased by 10-fold in PY and PYG. The high toxin production by C. difficile during growth in PY was lowered 100-fold by adding a blend of nine amino acids and several 60-100 kDa proteins were concomitantly down-regulated. It was concluded that toxin expression in C. difficile VPI 10463 was not affected by growth rate, growth phase, catabolite repression or the stringent response. Instead the co-expression of toxins and a few specific additional proteins appeared to be influenced by metabolic pathways involving CO2 assimilation, carboxylation reactions and metabolism of certain amino acids.  (+info)

Evaluation of two rapid assays for detection of Clostridium difficile toxin A in stool specimens. (8/1505)

Rapid laboratory diagnosis of Clostridium difficile-associated diarrhea (CDAD) is highly desirable in the setting of hospital cost containment. We tested 654 stool specimens to compare the performance of two assays for rapid detection of toxin A, the Immunocard Toxin A test (Meridian Diagnostics, Inc.) and the Culturette Brand Toxin CD enzyme immunoassay (EIA) (Becton Dickinson Microbiology Systems), with a cytotoxin assay (Cytotoxi Test; Advanced Clinical Diagnostics) and culture on cycloserine-cefoxitin-fructose agar followed by determination of the production of toxins A and B. A chart review was performed for patients whose stool specimens provided positive results on one to three of the assays. With the "gold standard" of all four assays positive or chart review evidence of CDAD, 97 (14.8%) stool specimens were positive by one or more assays and 557 (85.2%) were negative by all methods. Total agreement for all assays was 90.5% (592 of 654). The sensitivity, specificity, positive predictive value, and negative predictive value for toxigenic culture were 94.7, 98.6, 87.1, and 99.5%, respectively, for toxigenic culture; 87.7, 98.6, 86.2, and 98.8%, respectively, for the cytotoxin assay; 71.9, 99.3, 91.1, and 97.3%, respectively, for the Immunocard; and 68.4, 99.1, 88.6, and 96.9%, respectively, for the Culturette EIA. While easy to perform and highly specific, these rapid assays do not appear to be sufficient for accurate diagnosis of CDAD.  (+info)

Keywords:Chemotherapy, glutamate dehydrogenase test, real-time polymerase chain reaction, enzyme immunoassays, Clostridium difficile infection. Abstract: Clostridium difficile infection (CDI) is a major concern for health care system and clinicians. Interest in C. difficile infection has increased recently due to an ongoing C. difficile epidemic with a hypervirulent strain and mortality. Disease due to C. difficile is responsible for substantial strain on the hospital system by increasing patients length of stay and increasing costs. Present studies have demonstrated chemotherapeutic agents as an independent risk factor for CDI potentially leading towards serious morbidity and mortality. However, the current strategies ...
Clostridium difficile toxin A (TcdA) is a toxin generated by Clostridium difficile. It is similar to Clostridium difficile Toxin B. The toxins are the main virulence factors produced by the gram positive, anaerobic, Clostridium difficile bacteria. The toxins function by damaging the intestinal mucosa and cause the symptoms of C. difficile infection, including pseudomembranous colitis. TcdA is one of the largest bacterial toxins known. With a molecular mass of 308 kDa, it is usually described as a potent enterotoxin, but it also has some activity as a cytotoxin. The toxin acts by modifying host cell GTPase proteins by glucosylation, leading to changes in cellular activities. Risk factors for C. difficile infection include antibiotic treatment, which can disrupt normal intestinal microbiota and lead to colonization of C. difficile bacteria. The gene contains an open reading frame (ORF) of 8,133 nucleotides, coding for 2,710 amino acids. TcdA and TcdB share 63% homology in their amino acid ...
Clostridium difficile infection (CDI) is a symptomatic infection due to the spore-forming bacterium, Clostridium difficile. Symptoms include watery diarrhea, fever, nausea, and abdominal pain. It makes up about 20% of cases of antibiotic-associated diarrhea. Complications may include pseudomembranous colitis, toxic megacolon, perforation of the colon, and sepsis. Clostridium difficile infection is spread by bacterial spores found within feces. Surfaces may become contaminated with the spores with further spread occurring via the hands of healthcare workers. Risk factors for infection include antibiotic or proton pump inhibitors use, hospitalization, other health problems, and older age. Diagnosis is by stool culture or testing for the bacterias DNA or toxins. If a person tests positive but has no symptoms it is known as C. difficile colonization rather than an infection. Prevention is by limiting antibiotic use; and by hand washing, and terminal room cleaning in hospital. Discontinuation of ...

Glutamate dehydrogenase (GDH), an enzyme present in high copy numbers in many organisms, has proved to be a sensitive screening marker for Clostridium difficile. Since GDH is present in many intestinal bacteria, it is crucial that assay systems for glutamate dehydrogenase be accurate and highly sensitive for the detection of C. difficile-specific GDH. The RIDA®QUICK Clostridium difficile GDH immunochromatographic rapid test meets both of these requirements to a high degree. Although it does not eliminate the need for the detection of C. difficile toxins A and B, which is obligatory for the diagnosis of Clostridium difficile infection, the RIDA®QUICK Clostridium difficile GDH difficile rapid test improves the reliability of detection of this very consequential nosocomial pathogen when performed sequentially, i.e., before or parallel to the RIDA®QUICK Clostridium difficile Toxin A/B rapid test. Both the specific clinical symptoms and signs and the positive detection of C. difficile toxins A and ...
New advances in the treatment of Clostridium difficile infection (CDI) Dennis D Hedge, Joe D Strain, Jodi R Heins, Debra K FarverSouth Dakota State University College of Pharmacy, Brookings, SD 57007, USAAbstract: Clostridium difficile infections (CDI) have increased in frequency throughout the world. In addition to an increase in frequency, recent CDI epidemics have been linked to a hypervirulent C. difficile strain resulting in greater severity of disease. Although most mild to moderate cases of CDI continue to respond to metronidazole or vancomycin, refractory and recurrent cases of CDI may require alternative therapies. This review provides a brief overview of CDI and summarizes studies involving alternative antibiotics, toxin binders, probiotics, and immunological therapies that can be considered for treatment of acute and recurrent CDI in severe and refractory situations.Keywords: Clostridium difficile, antibiotics, probiotics, immunological therapy

Background. Previous studies have examined the association between proton pump inhibitor (PPI) use and the risk of Clostridium difficile-associated disease (CDAD), with conflicting results. Whether outpatient PPI use influences the risk of hospital admission for CDAD among older patients who have recently been treated with antibiotics is unknown.. Methods. We conducted a population-based, nested case-control study of linked health care databases in Ontario, Canada, from 1 April 2002 through 31 March 2005. We identified patients aged ⩾66 years who were hospitalized for CDAD within 60 days of receiving outpatient antibiotic therapy. Each case patient with CDAD was matched with 10 control subjects on the basis of age, sex, and details of antibiotic use (antibiotic class, timing, and number of antibiotics used). PPI use by case patients and control subjects was categorized as current (within 90 days), recent (91-180 days), or remote (181-365 days). We used conditional logistic regression to ...

What is C. difficile?. Clostridium difficile is a bacteria that can cause diarrhea, abdominal pain, fever, bowel inflammation (colitis), and rarely severe colitis (pseudomembranous colitis) and bowel perforation. In its spore (inert) form, it survives heat and frost in the environment; C. difficile spores usually pass through our guts without harm. However, certain triggers, such as antibiotics or proton pump inhibitors, cause C. difficile to grow and produce toxins. These toxins cause the symptoms of diarrhea. How is C. difficile spread?. C. difficile spores are spread on hands of sick patients and healthcare workers, and from surfaces and rooms that are not properly cleaned. Spores are not killed with typical disinfectants; so you need to use a fresh bleach solution (1:10 dilution) or special disinfectants. (EPA List K).. What is healthcare-associated C. difficile infection?. In an effort to address the causes of C. difficile infection (CDI), infections have been attributed to ...
Clostridium difficile infections cause morbidity and mortality. The authors conducted a retrospective review of Clostridium difficile infection (CDI) in kidney transplant recipients at their center over a 3 year period. The overall rate of CDI was 6.1% and increased over time during the study. A case-control study was subsequently performed to determine the risk factors for infection. Independent predictors of CDI among kidney transplant recipients were VRE colonization, having a CDC-criteria high risk donor, and administration of high-risk antibiotics such as antipseudomonal penicillins and carbapenems. There were no deaths in this series although 10.8% had recurrent infection. The study highlights the need for judicious antibiotic use and good infection control practices in transplant units.. ...
Clostridium difficile infections (CDI) are the most frequent cause of diarrhoea in hospitals. Geriatric patients are more often affected by the condition, by a relapse and complications. Therefore, a crucial question is how often colonization with toxigenic Clostridium difficile strains occurs in elderly patients without diarrhoea and whether there is a
Reduced susceptibility in some C. difficile isolates has been observed to metronidazole, a frontline antibiotic for C. difficile infection. Therefore, this study was performed to characterize reduced metronidazole susceptibility in UK C. difficile isolates, using phenotypic and genotypic approaches. This research focused on strains of three UK C. difficile ribotypes 027, 001, 106 including metronidazole reduced susceptible (CDRM) and metronidazole susceptible (CDSM) C. difficile strains, and 2 control strains from ribotype 010 (CDRM) and 038 (CDSM). An agar incorporation method (AIM) was used to determine the susceptibility and heterogeneity of minimum inhibitory concentrations (MICs). Ribotype 001 CDRM strains was observed for metronidazole to have the highest MIC90 (8mg/L) and the highest MIC hetereogeneity distributed across 2 MICs was observed in ribotype 106 at 22% and 11% for metronidazole and vancomycin respectively. All strains were susceptible to vancomycin at MIC ≤ 2mg/L which ...

Results:. An outbreak of C. difficile-associated diarrhea was caused by a clonal isolate of clindamycin-resistant C. difficile and was associated with increased use of clindamycin. Hospital-wide requirement of approval by an infectious disease consultant of clindamycin use led to an overall reduction in clindamycin use, a sustained reduction in the mean number of cases of C. difficile-associated diarrhea (11.5 cases/month compared with 3.33 cases/month; P , 0.001), and an increase in clindamycin susceptibility among C. difficile isolates (9% compared with 61%; P , 0.001). A parallel increase was noted in the use of and costs associated with other antibiotics with antianaerobic activity, including cefotetan, ticarcillin-clavulanate, and imipenem-cilastin. The hospital realized overall cost savings as a result of the decreased incidence of C. difficile-associated diarrhea. ...
Bacteria within biofilms are protected from multiple stresses, including immune responses and antimicrobial agents. The biofilm-forming ability of bacterial pathogens has been associated with increased antibiotic resistance and chronic recurrent infections. Although biofilms have been well studied for several gut pathogens, little is known about biofilm formation by anaerobic gut species. The obligate anaerobe Clostridium difficile causes C. difficile infection (CDI), a major health care-associated problem primarily due to the high incidence of recurring infections. C. difficile colonizes the gut when the normal intestinal microflora is disrupted by antimicrobial agents; however, the factors or processes involved in gut colonization during infection remain unclear. We demonstrate that clinical C. difficile strains, i.e., strain 630 and the hypervirulent strain R20291, form structured biofilms in vitro, with R20291 accumulating substantially more biofilm. Microscopic and biochemical analyses show ...
Author summary The anaerobic, spore-forming bacterium Clostridium difficile (C. difficile) is a prominent pathogen in hospitals worldwide and the leading cause of nosocomial diarrhea. Numerous risk factors are associated with C. difficile infections (CDIs) including: antibiotics, advanced age, vitamin D deficiency, and proton pump inhibitors. Antibiotic use disrupts the intestinal microbiota allowing for C. difficile to colonize, however, why these other risk factors increase CDI incidence is unclear. Notably, deficient intestinal calcium absorption (i.e., increased calcium levels) is associated with these risk factors. In this work, we investigate the role of calcium in C. difficile spore germination. C. difficile spores are the infectious particles and they must become metabolically active (germinate) to cause disease. Here, we show that calcium is required for C. difficile germination, specifically activating the key step of cortex hydrolysis, and that this calcium can be derived from either within
Quarterly epidemiological data on Clostridium difficile infection, Escherichia coli bacteraemia, Staphylococcus aureus bacteraemia and Surgical Site Infection in Scotland. April to June (Q2) 2017
A panel of experts was convened by the Infectious Diseases Society of America (IDSA) and Society for Healthcare Epidemiology of America (SHEA) to update the 2010 clinical practice guideline on Clostridium difficile infection (CDI) in adults. The update, which has incorporated recommendations for children (following the adult recommendations for epidemiology, diagnosis, and treatment), includes significant changes in the management of this infection and reflects the evolving controversy over best methods for diagnosis. Clostridium difficile remains the most important cause of healthcare-associated diarrhea and has become the most commonly identified cause of healthcare-associated infection in adults in the United States. Moreover, C. difficile has established itself as an important community pathogen.

Background Clostridium difficile is a Gram-positive bacteria found in the large bowel or colon that causes mild to severe intestinal conditions and sometimes death. The primary risk factors for development of Clostridium difficile infection (CDI) include healthcare exposure and recent antimicrobial use. The purpose of this study is to compare risk factors associated with CDI occurring in the Community to those associated with Healthcare Facility Associated CDI in the metro Atlanta population from September 1, 2009 - April 30, 2011. Methods Patients were identified through C. difficile surveillance program of the Georgia Emerging Infections Program (EIP). Prospective, population based, laboratory based surveillance for all positive C. difficile cases in the Georgia Health District 3 (HD3). Due to the sampling scheme, for this analysis CO-HCFA and HCFO cases were combined to make a Healthcare Facility Associated (HCFA) classification.

A woman suffering from a recurrent Clostridium difficile or C. difficile was recently successfully treated for infection with a stool transplant, but after the surgery she has gained considerable amount weight.. Stool transplant, known as fecal microbiota transplant (FMT) in technical term, is considered by the doctors as effective procedure for the treatment of recurrent C. difficile infections that can even turn fatal in some cases.. The C. difficile infection is considered to be a common reason for diarrhea related to antibiotic. With the overgrowth of the bacteria, dangerous toxins also begun to release that in turns attack the intestines lining, causing Clostridium difficile colitis.. An unnamed woman underwent a transplant of stool in 2011 for treating C. difficile infection. Before the procedure, her BMI was 26 and weighed 136 pounds. But she reported gaining an extra weight of around 34 pounds within 16 months of the surgery.. The stool was donated to a woman, whose identity is not ...

Clostridium difficile is mainly a nosocomial pathogen and is a significant cause of antibioticassociated diarrhea. It is also implicated in the majority of cases of pseudomembranous colitis. The main etiological agent of C. difficile-associated diarrhea (CDAD) is perturbations to the gut microbiota by broad-spectrum antibiotics. Recently, thuricin CD, a two-peptide narrow spectrum sactibiotic bacteriocin with potent activity against C. difficile has been discovered. It is produced by Bacillus thuringiensis DPC6431. The efficacy of thuricin CD against a range of C. difficile clinical isolates has been determined in the form of minimum inhibitory concentration (MIC) values and compared to metronidazole, vancomycin, ramoplanin and actagardine in this thesis. Furthermore, by assessing paired combinations of the above-mentioned antimicrobials, it was determined that ramoplanin and actagardine function in a synergistic manner against the majority of C. difficile isolates. The functions of the genes in ...

Clostridium difficile infection (CDI) has become a worldwide public health problem causing high mortality and a large disease burden. Molecular typing and analysis is important for surveillance and infection control of CDI. However, molecular characterization of C. difficile across China is extremely rare. Here, we report on the toxin profiles, molecular subtyping with multilocus sequence typing (MLST) and PCR ribotyping, and epidemiological characteristics of 199 C. difficile isolates collected between 2010 through 2015 from 13 participating centers across China. We identified 35 STs and 27 ribotypes (RTs) among the 199 C. difficile isolates: ST35 (15.58%), ST3 (15.08%), ST37 (12.06%), and RT017 (14.07%), RT001 (12.06%), RT012 (11.56%) are the most prevalent. One isolate with ST1 and 8 isolates with ST 11 were identified. We identified a new ST in this study, denoted ST332. The toxin profile tcdA+tcdB+tcdC+tcdR+tcdE+CDT- (65.83%) was the predominant profile. Furthermore, 11 isolates with positive
The Pennsylvania Health Care Cost Containment Council (PHC4) released a new research brief on Clostridium difficile infections-a common infection, often referred to as C. diff or CDI, that can cause severe suffering and can be life threatening. PHC4s research found that hospitalized patients with a CDI often have higher in-hospital mortality and readmission rates and tend to stay in the hospital longer. Hospital payments also tend to be higher for patients with a CDI. For patients hospitalized for congestive heart failure, patients with a CDI had in-hospital mortality rates that were double those for patients who did not have a CDI (5.6% compared to 2.8%), and they typically stayed in the hospital longer (7 days versus 4 days). Readmission rates for patients with a CDI were 39% higher (33.6% versus 24.2%). Estimated hospital payments averaged $13,711 compared to $9,380. The research brief also examines the impact these infections have on other common conditions such as sepsis, pneumonia and ...

Clostridium difficile is an important nosocomial pathogen, resulting in antibiotic-associated disease ranging from mild diarrhoea to the life-threatening pseudomembranous colitis. Upon antibiotic exposure, it is believed that the normal bowel microflora of patients is disrupted, allowing C. difficile to proliferate. Significantly, C. difficile is among only a few bacteria able to ferment tyrosine to p-cresol, a phenolic compound that is toxic to other microbes via its ability to interfere with metabolism. Therefore, the ability of different C. difficile strains to produce and tolerate p-cresol may play an important role in the development and severity of C. difficile-associated disease. In this study, it was demonstrated that two C. difficile hypervirulent 027 strains (Stoke Mandeville and BI-16) are more tolerant to p-cresol than other C. difficile strains including 630, CF4 and CD196. Surprising, it was shown that Clostridium sordellii also has a high tolerance to p-cresol, suggesting an overlap in
Although mostly associated with antibiotic use in hospitalized patients, C. difficile infections in people in the community have become more common. As of 2014, they accounted for 41 percent of all C. difficile infections, according to the Centers for Disease Control and Prevention (CDC). In this new case-control study, researchers enrolled adult patients from 10 U.S. sites during 2014-2015 who tested positive for C. difficile as an outpatient, or within three days of being hospitalized, and who had not been admitted to a health care facility within the past 12 weeks.. Each patient was matched to a person who did not have a C. difficile infection as a control. All of the study participants-452 total-were interviewed individually by phone to collect information about their health, medication use, recent health care visits, household exposures, and diet. In line with previous studies, larger percentages of patients with community-associated C. difficile infections had prior outpatient health care ...
In order to determine if gas-liquid chromatography (GLC) on concentrated stool extracts could be substituted to cell culture assay for cytotoxicity, we prospectively studied 154 diarrhoeal stools submitted for detection of Clostridium difficile toxin. Isocaproic-positive samples were cultured on egg yolk agar supplemented with cycloserine, cefoxitin and fructose for isolation of C difficile, and on egg yolk agar plus kanamycin for isolation of other clostridium species. Of the 154 samples, 129 were GLC-negative (height of the isocaproic peak less than 1.2 cm) and were toxin-negative. Twenty-five stools yielded isocaproic acid; C difficile isolated from 13 of them, six of which were also toxin-positive. Four other isocaproic-positive samples yielded C bifermentans and C sordellii; all were toxin-negative. These results indicate that a negative GLC is an excellent screening test for excluding C difficile infection; positive results must be checked by toxin testing and culture since they are not ...
Clostridium difficile, the most common cause of hospital-associated diarrhoea in developed countries, presents major public health challenges. The high clinical and economic burden from C. difficile infection (CDI) relates to the high frequency of recurrent infections caused by either the same or different strains of C. difficile. An interval of 8 weeks after index infection is commonly used to classify recurrent CDI episodes. We assessed strains of C. difficile in a sample of patients with recurrent CDI in Western Australia from October 2011 to July 2017. The performance of different intervals between initial and subsequent episodes of CDI was investigated. Of 4612 patients with CDI, 1471 (32%) were identified with recurrence. PCR ribotyping data were available for initial and recurrent episodes for 551 patients. Relapse (recurrence with same ribotype (RT) as index episode) was found in 350 (64%) patients and reinfection (recurrence with new RT) in 201 (36%) patients. Our analysis indicates ...

Cross-sectional studies suggest an increasing trend in incidence and relatively low recurrence rates of Clostridium difficile infections in Asia than in Europe and North America. The temporal trend of C. difficile infection in Asia is not completely understood. We conducted a territory-wide population-based observational study to investigate the burden and clinical outcomes in Hong Kong, China, over a 9-year period. A total of 15,753 cases were identified, including 14,402 (91.4%) healthcare-associated cases and 817 (5.1%) community-associated cases. After adjustment for diagnostic test, we found that incidence increased from 15.41 cases/100,000 persons in 2006 to 36.31 cases/100,000 persons in 2014, an annual increase of 26%. This increase was associated with elderly patients, for whom incidence increased 3-fold over the period. Recurrence at 60 days increased from 5.7% in 2006 to 9.1% in 2014 (p&lt;0.001). Our data suggest the need for further surveillance, especially in Asia, which contains ≈60
Clostridium difficile has become the leading cause of nosocomial diarrhea in adults. A substantial increase has occurred in morbidity and mortality associated with disease caused by C difficile and in the identification of new hypervirulent strains, warranting a high clinical index of suspicion for infections due to this organism. Prevention of infection requires a multidisciplinary approach, including early recognition of disease, effective contact isolation precautions, adherence to disinfectant policies, and judicious use of antibiotics. Current treatment approaches are based on the severity of illness. As hypervirulent strains evolve, unsuccessful treatments are more common. Complicated colitis caused by C difficile may benefit from surgical intervention. Subtotal colectomy and end ileostomy have been the procedures of choice, but are associated with a high mortality rate because of late surgical consultation and use of surgery as a salvage therapy. A promising surgical alternative is ...
TY - JOUR. T1 - Fecal microbiota transplantation for recurrent Clostridium difficile infection. AU - Brandt, Lawrence J.. AU - Reddy, Sheela S.. PY - 2011/11. Y1 - 2011/11. N2 - With the increasing prevalence of recurrent/refractory Clostridium difficile infection (CDI), alternative treatments to the standard antibiotic therapies are being sought. One of the more controversial of such alternative treatments is fecal microbiota transplantation (FMT). Although the notion of FMT is foreign - even startling - and not esthetic to most people, the concept has been around for many decades. Its benefit and efficacy dates back ,50 years to its use for staphylococcal pseudomembranous colitis, and now FMT is showing a great promise as an inexpensive, safe, and highly efficient treatment for recurrent and refractory CDI. Moreover, with a better understanding of the intricacies of the colonic microbiome and its role in colonic pathophysiology, FMT has the potential to become the standard of care for CDI ...
Clostridium difficile is the main cause of antibiotic associated diarrhea. In the past decade, the number of C. difficile patients has increased dramatically, coinciding with the emergence of two PCR ribotypes 027 and 078. PCR ribotype 078 is also frequently found during C. difficile outbreaks in pigfarms. Previously, the genome of the PCR ribotype 078 strain M120, a human isolate, was described to contain a unique insert of 100 kilobases. Analysis of this insert revealed over 90 open reading frames, encoding proteins originating from transposons, phages and plasmids. The insert was shown to be a transposon (Tn6164), as evidenced by the presence of an excised and circularised molecule, containing the ligated 5and 3ends of the insert. Transfer of the element could not be shown through filter-mating experiments. Whole genome sequencing of PCR ribotype 078 strain 31618, isolated from a diarrheic piglet, showed that Tn6164 was not present in this strain. To test the prevalence of Tn6164, a collection of
Low mannose-binding lectin concentration, but not genotype, was associated with disease recurrence in a large prospective cohort of patients with Clostridium difficile infection. Background. Mannose-binding lectin (MBL) plays a key role in the activation of the lectin-complement pathway of innate immunity, and its deficiency has been linked with several acute infections. However, its role in predisposing to, or modulating disease severity in, Clostridium difficile infection (CDI) has not been investigated. Methods. We prospectively recruited 308 CDI case patients and 145 control patients with antibiotic-associated diarrhea (AAD). CDI outcome measures were disease severity, duration of symptoms, 30-day mortality, and 90-day recurrence. Serum concentrations of MBL were determined using a commercial enzyme-linked immunosorbent assay transferred to an electrochemiluminescence-based platform. MBL2 polymorphisms were typed using a combination of pyrosequencing and TaqMan genotyping assays. Results. ...

Aim: To determine the ability of M. domestica larvae to acquire and retain C. difficile throughout their metamorphosis into adult flies. Methods: Larvae were exposed to spores of C. difficile in a faecal emulsion and examined externally and internally to determine carriage and internalisation of spores through their development to adults. Findings: Larvae harboured C. difficile externally, with means of 21.56 +/- 5.76 CFUs at day zero, ...
This study is a Phase 2 blinded, placebo-controlled, randomized clinical trial of an oral probiotic product, MIYA-BM Fine Granules [Clostridium butyricum MIYAIRI 588 Strain (CBM588)], in patients diagnosed with CDI and treated with metronidazole or vancomycin. Two hundred patients who meet all eligibility criteria will be randomized in a 1:1 fashion to receive either MIYA-BM (2g/dose) or placebo orally twice daily for 42 days. After randomization, all patients will be followed for a total of 180 days (6 months) for safety and recurrent CDI. If initially hospitalized, patients will be followed daily for diarrhea history, collection of concomitant medications and AEs, and monitored for their response to treatment. Patients will be followed through clinic visits and safety telephone calls. All patients will be given a Diary Card to report AEs, diarrhea history, and concomitant medications on a daily basis. If patients have signs or symptoms of CDI following resolution of the initial episode, they ...
Clostridium difficile and C. sordellii are two anaerobic, spore forming, gram positive pathogens with a broad host range and the ability to cause lethal infections. Despite strong similarities between the two Clostridial strains, differences in their host tissue preference place C. difficile infections in the gastrointestinal tract and C. sordellii infections in soft tissues. In this study, to improve our understanding of C. sordellii and C. difficile virulence and pathogenesis, we have performed a comparative genomic and phenomic analysis of the two. The global phenomes of C. difficile and C. sordellii were compared using Biolog Phenotype microarrays. When compared to C. difficile, C. sordellii was found to better utilize more complex sources of carbon and nitrogen, including peptides. Phenotype microarray comparison also revealed that C. sordellii was better able to grow in acidic pH conditions. Using next generation sequencing technology, we determined the draft genome of C.
Clostridium difficile, also known as C. diff, is a species of bacteria that causes severe diarrhea and other intestinal disease when competing bacteria in the gut have been wiped out by antibiotics (see Wikipedia entry). In rare cases a C. diff infection can progress to toxic megacolon which can be life-threatening. In a very small percentage of the adult population C. difficile bacteria naturally reside in the gut. Other people accidentally ingest spores of the bacteria while patients in a hospital or nursing home.. Validation:. True positive (for Gold standard cases): C. diff antigen / antibody positive or colonoscopy/flex sig positive for C. diff.. True positive (for Silver standard cases): the doctor believes they had C. diff colitis and treated them with an appropriate course of oral vancomycin (vancocin) or metronidazole (flagyl). ...
Fecal microbiota transplantation (FMT) involves administering fecal material from a healthy individual into the gastrointestinal tract of the patient. This has been done in the past for recurrent colitis secondary to Clostridium difficile infection (CDI) using different methods such as through nasogastric tube, fecal retention enemas, and by colonoscopy. This method of treatment was introduced over 50 years ago with high success rates, although it has not been until recent that more case studies have been performed, with continued success rates of approximately 90%. Studies have found this therapy to be effective with resolution of symptoms in most patients, and have found it to be both cost effective and safe.. The purpose of this study is to use a standardized published protocol for fecal microbiota transplantation performed by colonoscopy and record the success rate and outcomes of FMT therapy for patients with recurrent CDI at the UMassMemorial Medical Center. In addition, the cost of this ...

N2 - Introduction: Solid organ transplant (SOT) recipients are at high risk of Clostridium difficile infection (CDI) and CDI recurrence due to their suppressed immune systems and antibiotic exposure. A combination of metronidazole and oral vancomycin is often prescribed for SOT recipients with uncomplicated CDI despite any clinical practice guidelines supporting the need for combination therapy. This study aims to compare the CDI recurrence rates of metronidazole/vancomycin combination therapy to oral vancomycin monotherapy in SOT recipients after a first episode of uncomplicated CDI. Methods: A single-center retrospective cohort study evaluated SOT recipients diagnosed with uncomplicated CDI ...
Case Report: A 69-year-old man was admitted to the hospital after undergoing radical prostatectomy. The patient was given perioperative, intravenous cefazolin. On postoperative day 2, the patient developed an ileus and oliguric renal failure. Two days later, the patient developed a temperature of 101 °F and began receiving piperacillin-tazobactam treatment for hospital-acquired pneumonia. Three days after starting the treatment, the patient developed hypotension; worsening abdominal distention, and foul-smelling, watery diarrhea. The patient was subsequently transferred to the intensive care unit, given intravenous metronidazole for possible C. difficile infection, and put on vasopressors to stabilize his blood pressure. Continuous venovenous hemofiltration was initiated on postoperative day 10. The next day, rectal vancomycin treatment was started and piperacillin-tazobactam therapy was discontinued when a C. difficile toxin was detected. A sigmoidoscopy performed on postoperative day 24 ...

Clostridium difficile is a major cause of hospital acquired infection that poses significant diagnostic challenges. In this paper, a new type of resonant microwave applicator is proposed for the liberation of DNA from C. difficile spores via microwave disruption, followed by rapid detection using a sandwich hybridization assay. A split-ring resonator is designed to operate at 2.4 GHz with a 3 mm active gap region that contains an isolate volume of approximately 10 mm 3 , exposed to pulsed microwaves of 12 W rms power. The parallel electric field configuration maximizes the interaction between the microwaves and the sample. In a proof of principle study, in combination with pathogen specific DNA probes, we have used the system to correctly identify virulent strains of C. difficile using magnetic bead extraction of DNA suitable for point-of-care application. ...
Objectives: To examine biopsy specimens for histologic features suggestive of Clostridium difficile infection in patients with ulcerative colitis (UC). Methods: Nine patients with UC had colonic biopsy specimens taken during a symptomatic flare that coincided with positive C difficile (C difficile+) tests. Twenty-eight controls were biopsied during a UC flare but tested negative for C difficile. We reviewed the slides for evidence of pseudomembranes, ischemic-like changes, degree of colitis, and lamina propria hemorrhage. Results: In C difficile+ patients, 4 (44.4%) of 9 had microscopic pseudomembranes compared with 11% in controls (P < .05). Other histologic/clinical features were not predictive. Conclusions: Although the presence of microscopic pseudomembranes suggests C difficile infection in patients with UC, sensitivity and specificity are poor; biopsy findings do not reliably detect this infection in patients with UC ...
A stay in the hospital may not be the only way to acquire Clostridium difficile diarrhea -- but the potentially life-threatening infection may be associated with a number of health complications in hospitalized children, according to the findings from two studies unveiled today at the American College of Gastroenterologys 77th Annual Scientific meeting in Las Vegas.
After the first outbreak of Clostridium difficile PCR ribotype (RT) 027 in Germany in 2007, no further outbreaks were reported until the recent re-emergence of RT 027 in Hesse, a federal state with 6 million inhabitants located in south-west Germany. We undertook a survey to determine the prevalence of RT 027 and other strains in a prospective study. From January 2011 to July 2013, we analysed 291 specimens from patients diagnosed with C. difficile infection (CDI) in 40 healthcare facilities in Hesse. The mean incidence of CDI in hospitals including at least 10 patients in the survey was 9.9 per 10,000 patient days (range 4.8-22.8) in November 2012. We obtained 214 toxigenic C. difficile isolates. RT 001 was the most prevalent (31.8%). RT 027, the second most common type (26.6%), was prevalent in all hospitals (n=14) from which at least seven isolates were available for typing, but its frequency varied considerably (range: 9.1-70%). The annual frequency of RT 027 increased from 21.4% in 2011 to 30.0% in
To our knowledge, this is the first study to explore MRSA and C. difficile contamination, concurrently, in both patient rooms and the ward environment of a community hospital, longitudinally. The percentages of exposed patient rooms that were found to be contaminated with MRSA or C. difficile were lower compared to other studies [24-27]. This contrast in results may have been attributed to the number of patient rooms and surfaces investigated in addition to different sampling and culturing methodologies used among the studies.. Surfaces located in rooms with a C. difficile patient had increased odds of being contaminated with C. difficile compared to unexposed and MRSA exposed rooms, an unsurprising result given the potential for infected patients to contaminate their environment and the ability of C. difficile spores to survive in the hospital environment for months [8]. Interestingly, unexposed rooms were also identified as having a large number of surfaces contaminated with MRSA or C. ...
A diagnosis of pseudomembranous colitis is reached through a stool test. This test is different from normal stool culture, and is done to identify the toxin of the Clostridium difficile bacteria in the stool. The test for this toxin often gives a false negative result. Therefore, the doctor might order a repeat test if pseudomembranous colitis is still suspected. If the doubt still persists, a colonoscopy test might be done in order to identify the presence of any yellowish plaques of inflamed gut mucosa caused by pseudomembranous colitis.. Treatment of pseudomembranous colitis is through certain prescription antibiotics such as metronidazole, ridaximin or vancomycin. To stave off dehydration, enough water and other rehydration fluids must be taken. In some cases, pseudomembranous colitis may recur.. It is important to note that the stool of a person with pseudomembranous colitis is infectious. The infectious nature of the stool persists during the diarrheal period as well as for many weeks ...
Highly purified toxin A of Clostridium difficile was obtained by bovine thyroglobulin affinity chromatography followed by two sequential anion-exchange chromatography steps on Q Sepharose FF and Mono Q. After Q Sepharose FF chromatography of a thyroglobulin affinity-purified toxin A preparation, two major peaks of cytotoxicity representing toxins A and B were detected. The homogeneity of the final toxin A preparation obtained from Mono Q anion-exchange fast protein liquid chromatography was ascertained by gel electrophoresis developed by silver stain. The mol. wt of toxin A in non-denaturing conditions was estimated to be 520-540 Kda by native polyacrylamide gel electrophoresis (PAGE) developed by silver stain. In contrast, with sodium dodecyl sulphate (SDS)-PAGE under reducing or non-reducing conditions, a major band of 240 Kda and 10 minor and 27 faint bands (non-reduced conditions), or four minor and 31 faint bands (reduced conditions) were detected after silver staining. In two-dimensional PAGE, the
C. difficileis a bacterium known to cause colitis, with an estimated mortality rate of 6.5% in both non-severe and severe infections.9 Since 2003, CDI has increased in severity and has become more refractory to therapy.10 Historically, the treatment of CDI has been pharmacologically centered. However, nonantibiotic treatment for refractory, complicated cases have evolved and include fecal bacteriotherapy, probiotics, surgery, and monoclonal antibodies against C. difficile toxins.11,12. SBI is a newer nonantibiotic therapy. This plasma protein concentrate is approved by the U.S. Food and Drug Administration and is marketed as a medical food.13 Oral preparations of SBI are safe when administered in doses up to 20 g/d and are available by prescription.14 Routine follow-up is suggested to monitor for side effects. The most common complaints include mild nausea, constipation, stomach cramps, headache, and polyuria.3. In vitro, the mechanism of action of SBI occurs through immunoglobulin binding of ...
The epidemiology of CDI has been predominantly investigated in developed countries; however, few data are available in less developed countries and are reported mainly via case reports or reports of isolated hospital outbreaks (13-15). The incidence of ribotype 027 may be underevaluated in countries with limited resources owing to its recent emergence and/or limited availability of diagnostic testing. In the present survey, the estimated prevalence of CDI was lower than the European mean prevalence of seven cases/10.000 patient-days reported by the Euclid study (16). The case density was higher in specialized hospitals (H1 and H5) where patients with diarrhea are usually admitted. Recurrent CDI cases were exclusively managed at these hospitals. However, our data indicated a significant circulation of ribotype 027 in Romania. The global incidence of CDI may be underevaluated. Recently, a point prevalence study conducted at 482 hospitals across 20 European countries reported a high rate (23%) of ...
Clostridioides difficile is the leading cause of nosocomial infections and a worldwide urgent public health threat. Without doubt, there is an urgent need for new effective anticlostridial agents due to the increasing incidence and severity of C. difficile infection (CDI). The aim of the present study is to investigate the in vivo efficacy of auranofin (rheumatoid arthritis FDA-approved drug) in a CDI mouse model and establish an adequate dosage for treatment. The effects of increased C. difficile inoculum, and pre-exposure to simulated gastric intestinal fluid (SGF) and simulated intestinal fluid (SIF), on the antibacterial activity of auranofin were investigated. Auranofins in vitro antibacterial activity was stable in the presence of high bacterial inoculum size compared to vancomycin and fidaxomicin. Moreover, it maintained its anti-C. difficile activity after being exposed to SGF and SIF. Upon testing in a CDI mouse model, auranofin at low clinically achievable doses (0.125 mg/kg and 0.25 ...

I had cellulitis in my leg. As a diabetic, any infection in an extremity can be very dangerous, and I knew this and absolutely agreed this was not an inappropriate use of antibiotics. I am rather attached to my leg and want to keep it that way.. I was on two IV antibiotics in the hospital. When I left the hospital, my regular doctor prescribed 3 weeks of Clindamycin, which I also agreed with as the leg was still very red, obviously inflamed.. I also developed an open sore on top of the cellulitis, so he referred me to a place that specializes in wound care. I joked with the doctor there that wed save my leg, but Id wind up dying of C. diff and she recommended probiotics.. Well, I know something about probiotics - namely that we dont know squat about them. We know general things about them, but the specific details of what is good or bad about the hundreds of species of bacteria that live in us is sometimes sketchy.. (And sometimes useless.

Studies indicate that a toxin produced by Clostridium difficile is a primary cause of antibiotic-associated colitis. After it has been established that the primary diagnosis of pseudomembranous colitis, therapeutic measures should be initiated. In moderate to severe cases, consideration should be given management with fluids and electrolytes, protein supplementation and treatment with an antibacterial drug clinically effective against Clostridium difficile colitis. Although lincomycin appears that diffuses into the cerebrospinal fluid, levels of lincomycin to herein may not be suitable for the treatment of meningitis. Therefore, the drug should not be used in such treatment. If lincomycin therapy is prolonged, tests for liver and kidney function. The use of antibiotics may result in an overgrowth of non-susceptible organisms, particularly fungi ...
Pseudomembranous colitis is a complication of antibiotic therapy caused when a normal intestinal bacteria, Clostridium difficile, overgrows. The antibiotic kills other normal intestinal bacteria that keep Clostridium difficile in check.
To study growth characteristics of 17 commercial probiotic strains (Lactobacilli n=16, Bifidobacteria n=1) MRS broth was adjusted to pH 2 or 4 or supplemented with 0.15% or 0.3% bile. Growth was measured at 0 and 24h and compared spectrophotometrically to control growth in standard MRS broth. Growth under aerobic conditions was assessed. To evaluate inhibition of C. difficile and C. perfringens sterile supernatant of the probiotic culture was added to BHI inoculated with a standard C. difficile or C. perfringens suspension. Growth was measured spectrophotometrically at 0 and 24h and compared to the control (C. difficile or C. perfringens suspension in BHI). At pH 4 12% of strains showed ,50% growth and 24% were unable to grow, however did survive. At pH 2 none of the tested strains grew or survived. Eighty eight percent showed ,75% growth in 0.15% bile, 60% showed ,75% growth in 0.3% bile ...
Tooth Development The use of drugs of the tetracycline-class during tooth development (last half of pregnancy, infancy and childhood to the age of 8 years) may cause permanent discoloration of the teeth (yellow-gray-brown). This adverse reaction is more common during long-term use of the drugs but it has been observed following repeated short-term courses. Enamel hypoplasia has also been reported. Tetracycline drugs should not be used in this age group, except for anthrax, unless other drugs are not likely to be effective or are contraindicated.. Clostridium difficile Associated Diarrhea Clostridium difficile associated diarrhea (CDAD) has been reported with use of nearly all antibacterial agents, including tetracyclines, and may range in severity from mild diarrhea to fatal colitis. Treatment with antibacterial agents alters the normal flora of the colon leading to overgrowth of C. difficile.. C. difficile produces toxins A and B which contribute to the development of CDAD. Hypertoxin producing ...
In this paper in Molecular Microbiology, we describe our results that show that SpoIIQ and SpoIIIAH form a complex in C. difficile. This complex is essential for forespore engulfment and, surprisingly, also seems to be required for late stages of spore morphogenesis and gene expression control. This work highlights key differences between C. difficile and the model Gram-positive bacterium Bacillus subtilis, paving the way to a better understanding of sporulation mechanisms in C. difficile.

In Sweden, mares sometimes develop acute, often fatal, colitis when their foals are treated orally with erythromycin and rifampicin for Rhodococcus (R.) equi infection. Clostridium (C.) difficile, or its cytotoxin, was demonstrated in faecal samples from 5 of 11 (45%) mares with diarrhoea. By contrast C. difficile was not found in the faecal flora of 12 healthy mares with foals treated for R. equi infection or in 56 healthy mares with healthy untreated foals. No other enteric pathogen was isolated from any diarrhoeic mare. Of 7 investigated treated foals, 4 had a high (1651.0, 1468.3, 273.0 and 88.8 μg/g) faecal concentration of erythromycin. The dams of those 4 foals developed acute colitis, whereas the dams of 3 foals with a lower (26.3, 4.6 and 3.7 μg/g) faecal erythromycin concentration remained healthy, indicating that there might have been an accidental intake of erythromycin by mares. The foals treated with antibiotics were regarded as asymptomatic carriers and potential reservoirs, as ...
