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

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

C. difficile ribotype 027 (RT027) is the epidemic strain found primarily in North America. Studies have suggested an enhanced virulence phenotype for RT027 such as increased toxin production, but the impact on disease severity on in vivo models is not well understood. This study describes the in vitro characterization of important virulence characteristics for several RT027 and non-RT027 C. difficile clinical isolates, and how these factors may impact disease severity in the hamster and mouse C. difficile associated disease models. Six RT027 and six non-RT027 clinical isolates were evaluated in vitro for total spore counts and Toxin A/B titers in 72H broth cultures. Spore counts were generated from heat/ethanol shock culture samples and plated onto CCFA containing 0.1% taurocholate, and toxin A/B titers were determined from spent broth with the tgcBIOMICS ELISA assay. The mouse C. difficile model involved being administered for 5 days through oral gavage or drinking water. The mice were then placed on a
An increase in the incidence of clinical cases of Clostridium difficile infection has been reported in recent years, but few studies have examined changes in molecular epidemiology and antibiotic resistance over a long period of time. A collection of 179 isolates of C. difficile obtained from symptomatic adult patients in southern Scotland between 1979 and 2004 was used to determine changes in the prevalence of epidemiological types and antibiotic susceptibilities to common antibiotics. PCR ribotyping and MIC determination were performed on all isolates. A total of 56 different ribotypes were identified, among which ribotype 002 was the commonest type overall (14 .0%), followed by ribotypes 014 (7.3 %), 012 (5 .0%), 015 (5.0 %), 020 (5 .0%) and 001 (4.5 %). Ribotype 078 was also identified. The 10 commonest ribotypes comprised 55 % of the total isolates. Ribotype 001 increased in prevalence from 1.5 to 12.2 % over the study years, whereas the prevalence of ribotype 012 decreased from 8.7 to 2 .0%.
BACKGROUND: Clostridium difficile whole genome sequencing has the potential to identify related isolates, even among otherwise indistinguishable strains, but interpretation depends on understanding genomic variation within isolates and individuals. METHODS: Serial isolates from two scenarios were whole genome sequenced. Firstly, 62 isolates from 29 timepoints from three in vitro gut models, inoculated with a NAP1/027 strain. Secondly, 122 isolates from 44 patients (2-8 samples/patient) with mostly recurrent/on-going symptomatic NAP-1/027 C. difficile infection. Reference-based mapping was used to identify single nucleotide variants (SNVs). RESULTS: Across three gut model inductions, two with antibiotic treatment, total 137 days, only two new SNVs became established. Pre-existing minority SNVs became dominant in two models. Several SNVs were detected, only present in the minority of colonies at one/two timepoints. The median (inter-quartile range) [range] time between patients first and last samples was
Hybridization of EcoRI- and HindIII-digested chromosomal DNAs from 41 isolates of Enterococcus faecalis with probes for rRNA genes was performed (ribotyping). The ability of ribotyping to distinguish strains at the subspecies level was compared with results previously determined by pulsed-field gel electrophoresis (PFGE). With EcoRI, seven ribopatterns (usually differing by only one band) were found, while PFGE had previously shown 25 clearly different patterns plus six related variants. Digestion with HindIII generated a few additional patterns but still failed to differentiate some strains that had very different PFGE patterns. Ribotyping with BscI has also been reported to be inadequate for subspecies strain differentiation (L. M. Hall, B. Duke, M. Guiney, and R. Williams, J. Clin. Microbiol. 30:915-919, 1992). Although ribotyping with other restriction endonucleases may perform better in distinguishing different strains, at present PFGE appears to be superior for strain differentiation. ...
Ribotype 027 strains have been frequently shown to be overrepresented in hospital outbreaks and have been linked to increased morbidity and mortality. Although this association with a hypervirulent state is controversial, the fact that ribotype 027 strains have swept across the globe implies they have acquired an increased ability to cause disease. We hypothesized that differences in strain physiology could give ribotype 027 strains a competitive advantage over strains of other ribotypes, thereby leading to the increased prevalence of ribotype 027 strains. We used the MBRA C. difficile invasion model to demonstrate that ribotype 027 strains were able to outcompete strains of other ribotypes in the presence of complex fecal bacterial communities. We then demonstrated competitive advantages of ribotype 027 strains similar to those of strains of other ribotypes in a mouse model of C. difficile infection.. Our work demonstrates that ribotype 027 strains can directly outcompete strains of other ...

Clostridioides difficile ribotype (RT) 019/sequence type (ST) 67 strains belong to a hypervirulent lineage closely related to RT027/ST1; however, limited data are available for hypervirulent clade 2 lineages in Japan. Herein, we report the draft genome of a C. difficile strain B18-123 belonging to clade 2, RT019/ST67 for the first time in Japan. The pathogenicity locus carried by B18-123 (19.6 kb) showed higher homology (97.29% nucleotide identity) with strain R20291 (RT027/ST1) than the reference strain 630 (RT012/ST54), and B18-123 harbored 8-nucleotide substitutions in tcdC. However, it did not contain an 18-base pair (bp) deletion or a single-bp deletion at position 117 in tcdC, which was identified in the previous strain R20291. A cytotoxicity assay revealed similar cytotoxicity levels between strains B18-123 and ATCC BAA-1870 (RT027/ST1). The B18-123 strain was found to be susceptible to metronidazole and vancomycin. Our findings contribute to the further understanding of the characteristics of

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 ...
A total of 486 Listeria monocytogenes isolates originating from 17 Finnish food processing plants (representing meat, poultry, fish, and dairy production) were collected and typed by automated ribotyping using EcoRI as the restriction enzyme. The isolates were divided into 16 different ribotypes (RTs). Some of these isolates (121), representing all EcoRI types and 16 food plants, were subjected to ribotyping with the PvuII enzyme, to pulsed-field gel electrophoresis (PFGE) typing with AscI and SmaI restriction enzymes, and to serotyping with O-antigen antisera. Nineteen ribotypes were generated with PvuII, 42 macrorestriction patterns were generated with AscI and 24 with SmaI, and three serotypes were generated with antisera. When the results were combined, the overall number of RTs was 23, and that of the PFGE types was 46. Thus, the overall discrimination power of PFGE was higher (discrimination index [DI] 0.966) than that of ribotyping (DI 0.906). The most common serotype (90.1% of the isolates) was
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
Discrimination by automatic ribotyping and random amplified polymorphic DNA PCR, RAPD, was compared for 40 different B. cereus dairy isolates, 4 different B. mycoides isolates and 6 culture collection strains. RAPD-PCR has previously shown to be useful for tracing contamination routes of B. cereus to milk. Automatic ribotyping using EcoRI and PvuII separated the B. cereus and B. mycoides isolates/strains into 36 different ribotypes. RAPD-typing with primers generated 40 different RAPD-profiles. However, 17 isolates clustered into eight groups, irrespective of the primer and restriction enzyme used, and in all but one case, the isolates with the same pattern were isolated from the same dairy. Automatic ribotyping proved to be a useful, standardized and quick method to discriminate between B. cereus strains, only slightly less discriminatory than RAPD-typing.. ...

Clostridium difficile has rapidly emerged as the leading cause of antibiotic-associated diarrheal disease, with the transcontinental spread of various PCR ribotypes, including 001, 017, 027 and 078. However, the genetic basis for the emergence of C. difficile as a human pathogen is unclear. Whole genome sequencing was used to analyze genetic variation and virulence of a diverse collection of thirty C. difficile isolates, to determine both macro and microevolution of the species. Horizontal gene transfer and large-scale recombination of core genes has shaped the C. difficile genome over both short and long time scales. Phylogenetic analysis demonstrates C. difficile is a genetically diverse species, which has evolved within the last 1.1-85 million years. By contrast, the disease-causing isolates have arisen from multiple lineages, suggesting that virulence evolved independently in the highly epidemic lineages.. ...
Our study showed presence of CDI in 122 of the 1,532 patients (prevalence of 7.9% during the period 2011 to 2012; 6.4% of which were hospital acquired). Amongst the hospital acquired patients, 5.7% (n = 87/1,532) were from Hamad General Hospital and 0.7% (n = 11/1,532) from Al Khor Hospital. The reason for the large difference between the hospitals is probably due to the presence of more patient samples, in our study, from Hamad General Hospital vs. Al Khor Hospital. Of the 122 CDI positive patients 98 (80.3%) had hospital acquired CDI and 14 (11.8%) had community-acquired CDI. The prevalence data found in our study are comparable to data from other Middle-Eastern countries (prevalence range 4.6-13.7%; average ~8.6%) [14-18]. Comparatively, in Europe C. difficile infections are responsible for only 3.6% of all hospital acquired infections [19]. The difference may be attributed to over-prescription of antibiotics in the Middle East. However, it must be noted that the sample sizes used in this ...
Title: Clostridium Difficile Infection Following Chemotherapy. VOLUME: 5 ISSUE: 1. Author(s):Shahzad Raza, Mahadi A. Baig, Helena Russell, Yanick Gourdet and Barbara J. Berger.

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 ...

The continued rise of Clostridium difficile infections worldwide has been accompanied by the rapid emergence of a highly virulent clone designated PCR-ribotype 027. To understand more about the evolution of this virulent clone, we made a three-way genomic and phenotypic comparison of an historic non-epidemic 027 C. difficile (CD196), a recent epidemic and hypervirulent 027 (R20291) and a previously sequenced PCR-ribotype 012 strain (630). Although the genomes are highly conserved, the 027 genomes have 234 additional genes compared to 630, which may contribute to the distinct phenotypic differences we observe between these strains relating to motility, antibiotic resistance and toxicity. The epidemic 027 strain has five unique genetic regions, absent from both the non-epidemic 027 and strain 630, which include a novel phage island, a two component regulatory system and transcriptional regulators. A comparison of a series of 027 isolates showed that some of these genes appeared to have been gained by
Clostridium difficile was isolated from 12 (20%) of 60 retail ground meat samples purchased over a 10-month period in 2005 in Canada. Eleven isolates were toxigenic, and 8 (67%) were classified as toxinotype III. The human health implications of this finding are unclear, but with the virulence of toxinotype III strains further studies are required.
Testing is generally not necessarily for patients with formed stools (no diarrhea). The gold standard for diagnosis of C. difficile infection is cell culture cytotoxic assay, but it is rarely used clinically (difficult technique and time consuming). Among patients with diarrhea,C. difficile infection is diagnosed either by enzyme immunoassay (ELISA) for toxins A and/or B in stools or by DNA-based tests (PCR) that detect bacterial toxin genes in stools. Although both ELISA and DNA-based tests may be performed sequentially, only one positive test is sufficient to diagnose C. difficile infection. Both ELISA and DNA-based tests also have a high negative predictive value , 95% among average-risk patients, and generally negative results warrants the search for alternative diagnoses. The advantage of DNA-based tests over ELISA is that it may detect the presence of BI/NAP1/027 strain, which alters the management plan. However, DNA-based tests may also detect clinically irrelevant findings that may delay ...

One way of identifying and categorizing multiple bacterial organisms in a sample is to use ribotyping.[37] In ribotyping, differing lengths of chromosomal DNA are isolated from samples containing bacterial species, and digested into fragments.[37] Similar types of fragments from differing organisms are visualized and their lengths compared to each other by Southern blotting or by the much faster method of polymerase chain reaction (PCR).[37] Fragments can then be matched with sequences found on bacterial species.[37] Ribotyping is shown to be a method to isolate bacteria capable of spoilage.[38] Around 51% of Pseudomonas bacteria found in dairy processing plants are P. fluorescens, with 69% of these isolates possessing proteases, lipases, and lecithinases which contribute to degradation of milk components and subsequent spoilage.[38] Other Pseudomonas species can possess any one of the proteases, lipases, or lecithinases, or none at all.[38] Similar enzymatic activity is performed by Pseudomonas ...

Clostridium difficile infection (CDI) is a potentially fatal bacterial infection that leads to 3,700 deaths a year in Europe, yet almost two-thirds of CDI cases are missed because clinicians fail to request tests for C. difficile toxins. When CDI remains undiagnosed and untreated, it not only endangers patients health, it also poses a serious cost to healthcare systems.

The non-toxigenic variant of Clostridium difficile is prevalent in clinical samples. The reason for the high prevalence of these strains in the clinical diarrhea specimens has not yet been studied.Evaluation of spore production in non-toxigenic C. difficile isolates (A-/B-/CDT-) compared to toxigenic isolates (A+/B+/CDT-) in the absence and presence of antibiotics.Minimum inhibitory concentration (MIC) for bacteria was performed by the microdilution technique. About ~106 bacteria from 18-hour culture were inoculated to pre-reduced media containing ½ × MIC of vancomycin (VAN), clindamycin (CLI) and ceftazidime (CAZ). After 24, 48, and 96 hours, one milliliter of broth culture was added and heated for killing vegetative forms. One hundred microliters of appropriate dilution were cultured on Columbia blood agar in triplicate. After 72 hours, the number of viable spores was counted based on the colony forming unit.The result showed the spore production of non-toxigenic C. difficile isolates in free
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.

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 ...
To determine the presence of Clostridium difficile, we sampled cooked and uncooked meat products sold in Tucson, Arizona. Forty-two percent contained toxigenic C. difficile strains (either ribotype 078/toxinotype V [73%] or 027/toxinotype III [NAP1 or NAP1-related; 27%]). These findings indicate that food products may play a role in interspecies C. difficile transmission ...
TY - JOUR. T1 - Control of Clostridium difficile infection in the hospital setting. AU - Wiuff, C. AU - Murdoch, H. AU - Coia, JE. PY - 2014/3. Y1 - 2014/3. N2 - Clostridium difficile infection (CDI) has emerged as a leading challenge in the control of healthcare-associated infection (HCAI). The epidemiology of CDI has changed dramatically, this is associated with emergence of hypervirulent strains, particularly PCR ribotype 027. Despite the epidemic spread of these strains, there are recent reports of decreasing incidence from healthcare facilities where multi-facetted targeted control programs have been implemented. We consider these changes in epidemiology and reflect on the tools available to control CDI in the hospital setting. The precise repertoire of measures adopted and emphasis on different interventions will vary, not only between healthcare systems, but also within different institutions within the same healthcare system. Finally, we consider both the sustainability of reductions ...
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 ...

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<0.001). Our data suggest the need for further surveillance, especially in Asia, which contains ≈60
High-risk patients must be warned about proton pump inhibitors and Clostridium difficile infection, as community-acquired C. difficile infections increase.
Clostridium difficile (CD) has increasingly become recognised as a significant international health burden, often associated with the healthcare environment. The upsurge in incidence of CD coincided with the emergence of a hypervirulent strain of CD characterized as 027. In 2010, 8 cases of CD 027 infections were identified in Italy. Since then, no further reports have been published. We describe 10 new cases of CD 027 infection occurring in Italy. Since December 2010, stool samples of patients with severe diarrhea and clinical suspicion of the presence of a hypervirulent strain, were tested for CD 027 by the Xpert C. difficile PCR assay (Cepheid, Sunnyvale, CA). Clinical, epidemiological and laboratory data were collected. From December 2010 to April 2012, 24 faecal samples from 19 patients who fit the above criteria were submitted to our laboratory. Samples were collected from 7 different hospitals. Of these, 17 had a positive PCR for CD and 10 were the epidemic 027 strain (59%). All PCR positive

In the USA: Nearly half a million Americans suffer from Clostridium difficile (C. diff.) infections in a single year according to a study released in 2015 by the Centers for Disease Control and Prevention (CDC). Approximately 29,000 patients died within 30 days of the initial diagnosis of C. difficile. Of those, about 15,000 deaths were estimated to be directly attributable to C. difficile infections making C. difficile a very important cause of infectious disease death in the United States.
Introduction. Clostridium difficile infection (CDI) epidemiology has changed dramatically in recent decades and has become an important worldwide health problem. The appearance of increasingly more virulent strains, inadequate antibiotic use, and the aging of a population affected by a larger number of chronic and debilitating diseases are factors that have increased the incidence of CDI, with the consequent rise in morbidity, mortality, and healthcare costs. Thus, CDI has gone from being a strictly nosocomial infection to a problem that is frequently community-acquired, with a broad clinical presentation spectrum. Mexico is no exception and different studies on this health problem, some of which have been published in the Revista de Gastroenterología de México, have caught the attention of the medical community.. In October of 2017, the Asociación Mexicana de Gastroenterología brought together a multidisciplinary group of healthcare professionals made up of gastroenterologists, ...

As someone who suffered through a nasty Clostridium difficile infection in my colon and its rather unpleasant aftermath, I live to tell about it.
C. difficile infections occur when someone is taking antibiotics.. The antibiotics destroy the good bacteria that usually protect patients, leaving C. difficile bacteria to take over.. Essentially the symptoms are diarrhea. That may not sound too bad, but for the elderly it can be deadly. The CDC associates C. difficile with 14,000 deaths a year.. The bacteria can be killed relatively easily, ironically enough with antibiotics. But the spores are hardy.. The author of the report, CDC epidemiologist Dr. Clifford McDonald, says the spores arent killed by hand washing - even with antibacterial soap - and they can last months out in the open.. In the past a lot of C. difficle infections were considered to happen just generally in the community. But this report shows that most of these so called community infections actually occur in people with recent exposure to medical facilities.. Dr. Ileana Arias, the deputy director of the CDC, says the good news is that C. difficile infections are very ...
Clostridium difficile strain 630Δerm is a spontaneous erythromycin sensitive derivative of the reference strain 630 obtained by serial passaging in antibiotic-free media. It is widely used as a defined and tractable C. difficile strain. Though largely similar to the ancestral strain, it demonstrates phenotypic differences that might be the result of underlying genetic changes. Here, we performed a de novo assembly based on single-molecule real-time sequencing and an analysis of major methylation patterns. In addition to single nucleotide polymorphisms and various indels, we found that the mobile element CTn5 is present in the gene encoding the methyltransferase rumA rather than adhesin CD1844 where it is located in the reference strain. Together, the genetic features identified in this study may help to explain at least part of the phenotypic differences. The annotated genome sequence of this lab strain, including the first analysis of major methylation patterns, will be a valuable

What is C. difficile? C. difficile (Clostridium difficile) is a bacteria that can either live in the bowel as part of normal bowel flora without causing harm, or it can cause an infection (diarrhea, fever, abdominal pain).
Over the past several years nationwide, states have reported increased rates of C. difficile infection, noting more severe disease and an associated increase in mortality. C. diff infection remains a disease mostly associated with healthcare (at least 80%) Patients most at risk remain the elderly, especially those using antibiotics. Although the elderly are still most affected, more disease has been reported in traditionally low risk persons such as healthy persons in the community, and peripartum women. These changes may be largely due to the new emergence of the current epidemic strain of C. difficile, known by its names assigned by various typing schemes as restriction enzyme analysis type BI, North American Pulsed Field type 1 (NAP1), or PCR ribotype 027. BI/NAP1/027 has spread widely after first being found responsible for outbreaks in Pittsburgh (2000), Atlanta (2001-2), and Montreal (2003). This strain appears more virulent possibly due to its increased production of toxins A and B and ...

A novel approach to prevent C. difficile infection is to use compounds with activity against C. difficile as primary prophylaxis in high risk patients. Chemoprophylaxis theoretically can prevent C. difficile infection by two mechanisms. It may reduce transmission from asymptomatic C. difficile carriers by reducing the number of spores shed in the stool and prevent replication and subsequent toxin production of the organisms in patients at risk for C. difficile infection ...
