Clindamycin plus gentamicin as expectant therapy for presumed mixed infections. (1/3200)The prevalence of obligate anaerobes was studied prospectively in 60 patients with severe sepsis of intra-abdominal, soft tissue, female genital or oropulmonary origin. In addition, the efficacy of clindamycin (for anaerobes) plus gentamicin (for aerobic bacteria, especially coliforms) as initial empiric therapy in these patients was evaluated. Among 54 patients with cultural proof of infection, anaerobic pathogens were recovered from 52%. Nineteen patients had bacteremia; Bacteroides fragilis and Klebsiella pneumoniae were the most prevalent pathogens, being isolated in five patients each. Infection was eradicated in 56 of the 60 patients (93%). Mortality related to sepsis was 7% in the entire group, 16% in patients with bacteremia and 2% in patients without bacteremia. Eighty-five percent of aerobic isolates tested were susceptible in vitro to either gentamicin or clindamycin; 97% of anaerobic isolates were inhibited by 5 mug/ml of clindamycin. (+info)
Route and type of nutrition influence mucosal immunity to bacterial pneumonia. (2/3200)OBJECTIVE: To develop a model of established respiratory immunity against Pseudomonas aeruginosa pneumonia and to investigate the effects of route and type of nutrition on this immunity. SUMMARY BACKGROUND DATA: Diet influences the ability of gut-associated lymphoid tissue (GALT) to maintain mucosal immunity. Complex enteral diets and chow maintain normal GALT populations against established IgA-mediated antiviral respiratory immunity. Both intravenous and intragastric total parenteral nutrition (TPN) produce GALT atrophy, but only intragastric TPN preserves established antiviral immunity. The authors hypothesized that both GALT-depleting diets (intragastric and intravenous TPN) would impair immunity against bacterial pneumonia. METHODS: P. aeruginosa was administered intratracheally to determine the mortality rate at increasing doses, and liposomes containing P. aeruginosa antigens were used to generate effective respiratory immunization. In the final experiment, mice received liposomes containing P. aeruginosa antigens to establish immunity and then were randomized to chow, complex enteral diets, intragastric TPN, or intravenous TPN. After 5 days of diet, mice received live intratracheal P. aeruginosa, and the death rate was recorded at 24 and 48 hours. RESULTS: The LD50 and LD100 were 9 x 10(7) and 12 x 10(7), respectively. Immunization reduced the mortality rate from 66% to 12%. This immunization was maintained in mice fed chow or a complex enteral diet and was lost in animals receiving intravenous TPN. Intragastric TPN partially preserved this respiratory immunity. CONCLUSIONS: Protection against bacterial pneumonia can be induced by prior antigenic immunization. This protection is lost with intravenous TPN, partially preserved with a chemically defined enteral diet, and completely preserved with chow or complex enteral diets. Both route and type of nutrition influence antibacterial respiratory tract immunity. (+info)
Cystic fibrosis transmembrane conductance regulator-mediated corneal epithelial cell ingestion of Pseudomonas aeruginosa is a key component in the pathogenesis of experimental murine keratitis. (3/3200)Previous findings indicate that the cystic fibrosis transmembrane conductance regulator (CFTR) is a ligand for Pseudomonas aeruginosa ingestion into respiratory epithelial cells. In experimental murine keratitis, P. aeruginosa enters corneal epithelial cells. We determined the importance of CFTR-mediated uptake of P. aeruginosa by corneal cells in experimental eye infections. Entry of noncytotoxic (exoU) P. aeruginosa into human and rabbit corneal cell cultures was inhibited with monoclonal antibodies and peptides specific to CFTR amino acids 108 to 117. Immunofluorescence microscopy and flow cytometry demonstrated CFTR in the intact murine corneal epithelium, and electron microscopy showed that CFTR binds to P. aeruginosa following corneal cell ingestion. In experimental murine eye infections, multiple additions of 5 nM CFTR peptide 103-117 to inocula of either cytotoxic (exoU+) or noncytotoxic P. aeruginosa resulted in large reductions in bacteria in the eye and markedly lessened eye pathology. Compared with wild-type C57BL/6 mice, heterozygous DeltaF508 Cftr mice infected with P. aeruginosa had an approximately 10-fold reduction in bacterial levels in the eye and consequent reductions in eye pathology. Homozygous DeltaF508 Cftr mice were nearly completely resistant to P. aeruginosa corneal infection. CFTR-mediated internalization of P. aeruginosa by buried corneal epithelial cells is critical to the pathogenesis of experimental eye infection, while in the lung, P. aeruginosa uptake by surface epithelial cells enhances P. aeruginosa clearance from this tissue.

The sialylation of bronchial mucins secreted by patients suffering from cystic fibrosis or from chronic bronchitis is related to the severity of airway infection. (4/3200)Bronchial mucins were purified from the sputum of 14 patients suffering from cystic fibrosis and 24 patients suffering from chronic bronchitis, using two CsBr density-gradient centrifugations. The presence of DNA in each secretion was used as an index to estimate the severity of infection and allowed to subdivide the mucins into four groups corresponding to infected or noninfected patients with cystic fibrosis, and to infected or noninfected patients with chronic bronchitis. All infected patients suffering from cystic fibrosis were colonized by Pseudomonas aeruginosa. As already observed, the mucins from the patients with cystic fibrosis had a higher sulfate content than the mucins from the patients with chronic bronchitis. However, there was a striking increase in the sialic acid content of the mucins secreted by severely infected patients as compared to noninfected patients. Thirty-six bronchial mucins out of 38 contained the sialyl-Lewis x epitope which was even expressed by subjects phenotyped as Lewis negative, indicating that at least one alpha1,3 fucosyltransferase different from the Lewis enzyme was involved in the biosynthesis of this epitope. Finally, the sialyl-Lewis x determinant was also overexpressed in the mucins from severely infected patients. Altogether these differences in the glycosylation process of mucins from infected and noninfected patients suggest that bacterial infection influences the expression of sialyltransferases and alpha1,3 fucosyltransferases in the human bronchial mucosa.

Cellular fatty acids and metabolic products of Pseudomonas species obtained from clinical specimens. (5/3200)The cellular fatty acid composition of 112 reference strains and clinical isolates of Pseudomonas species was determined by gas-liquid chromatography (GLC). The presence and relative amounts of cyclopropane, hydroxy, and branched-chain fatty acids were distinguishing features of these strains. Determination of short-chain fatty acids extracted from spent growth media provided an additional means for identifying some strains. Our results show that clinical isolates of pseudomonads can be divided into eight distinct GLC groups. The procedures were especially useful for distinguishing glucose-nonoxidizing pseudomonads, which are difficult to identify by conventional criteria. Since the GLC procedures are simple, rapid, and highly reproducible, they are useful in diagnostic laboratories that process large numbers of cultures. Coupled with selected conventional tests, the analysis of short-chain and cellular fatty acids can be very useful for rapid screening of clinical isolates of Pseudomonas species. (+info)
Pathogenesis of experimental Pseudomonas keratitis in the guinea pig: bacteriologic, clinical, and microscopic observations. (6/3200)Uniformly severe corneal infections were produced in guinea pigs by intracorneal injection of about 10 viable Pseudomonas aeruginosa. After a brief lag period, multiplication of bacteria was rapid, reaching geometric means of 280,000 after 24 hr and of 5 million after 48 hr. Within 8 hr after inoculation, polymorphonuclear leukocytes (PMNs) began to infiltrate the anterior two thirds of the stroma. Stromal cells adjacent to the injection site became necrotic and appeared to be engulfed by PMNs. By 14 to 16 hr, an abscess containing a dense aggregate of PMNs and multiplying bacteria developed in the central stroma. By 16 to 24 hr, collagen breakdown was apparent within and around the abscess. Ultrastructural evidence of collagen breakdown included loss of intact collagen fibrils, tactoid formation, and accumulation of amorphous electron-dense material. The area of liquefactive necrosis gradually enlarged, and many corneas perforated after 3 to 4 days. Because the course of infection is highly reproducible, this model should prove useful for many studies of experimental Pseudomonas keratitis. (+info)
Bacteriologic cure of experimental Pseudomonas keratitis. (7/3200)Two long-term therapy trials with high concentrations of antibiotic were carried out to determine the duration of therapy required to achieve bacteriologic cure of experimental Pseudomonas keratitis in guinea pigs. In the first study, corneas still contained Pseudomonas after 4 days of continual topical therapy with either tobramycin 400 mg/ml, amikacin 250 mg/ml, ticarcillin 400 mg/ml, or carbenicillin 400 mg/ml. In an 11-day trial of topical therapy with tobramycin 20 mg/ml, 34 of 36 corneas grew no Pseudomonas after 6 or more days of therapy. The bacteriologic response to therapy in this model occurred in two phases. About 99.9% or more of the organisms in the cornea were killed in the first 24 hr of therapy. The numbers of bacteria remaining in the cornea declined gradually over the next several days until the corneas were sterile. Optimal antibiotic therapy may include two stages: initial intensive therapy with high concentrations of antibiotic applied frequently to achieve a large rapid decrease in numbers of organisms in the cornea, followed by prolonged, less intensive therapy to eradicate organisms and prevent relapse.

Comparison of flagellin genes from clinical and environmental Pseudomonas aeruginosa isolates. (8/3200)Pseudomonas aeruginosa, an important opportunistic pathogen, was isolated from environmental samples and compared to clinically derived strains. While P. aeruginosa was isolated readily from an experimental mushroom-growing unit, it was found only rarely in other environmental samples. A flagellin gene PCR-restriction fragment length polymorphism analysis of the isolates revealed that environmental and clinical P. aeruginosa strains are not readily distinguishable. The variation in the central regions of the flagellin genes of seven of the isolates was investigated further. The strains used included two strains with type a genes (998 bp), four strains with type b genes (1,258 bp), and one strain, K979, with a novel flagellin gene (2,199 bp). The route by which flagellin gene variation has occurred in P. aeruginosa is discussed. (+info)
Pseudomonas aeruginosa bloodstream infection (BSI) is predominantly acquired in the hospital setting. Community-onset infection is less common. Differences in epidemiology, clinical features, microbiological factors and BSI outcomes led to the separation of bacterial community-onset BSI into the categories of healthcare-associated infection (HCAI) and community-acquired infection (CAI). Community-acquired P. aeruginosa BSI epidemiology is not well defined in the literature. In addition, it is also not clear if the same factors separate CAI and HCAI BSI caused by P. aeruginosa alone. A retrospective multicentre cohort study was performed looking at P. aeruginosa BSI from January 2008 to January 2011. Strict definitions for HCAI and CAI were applied. Extensive epidemiological, clinical and outcome data were obtained. Thirty-four CAI episodes and 156 HCAI episodes were analysed. The CAI group could be characterised into seven distinct categories based on comorbidities and clinically suspected ...
Pseudomonas infections are diseases caused by a bacterium from the genus Pseudomonas. The bacteria are found widely in the environment, such as in soil, water, and plants. They usually do not cause infections in healthy people. If an infection does occur in a healthy person, it is generally mild. More severe infections occur in people who are already hospitalized with another illness or condition, or people who have a weak immune system. Pseudomonades are fairly common pathogens involved in infections acquired in a hospital setting. A pathogen is a microorganism that causes disease. Infections acquired in a hospital are called nosocomial infections. Infections can occur in any part of the body. Symptoms depend on which part of the body is infected. Antibiotics are used to treat the infections. Pseudomonas infection could be fatal in people who are already very ill.. ...

CF is an inherited disease that causes mucus to build up in the lungs and digestive tract, which can cause lung infections and digestive problems. It is the most common type of chronic lung disease in children and young adults and may result in early death. There is no cure for this disease. The primary cause of death in individuals with CF is progressive obstructive pulmonary disease associated with chronic Pseudomonas aeruginosa (PA) infection. PA infection can occur early in life and can become highly resistant to antibiotics. Once an individual has been diagnosed with chronic PA infection, it is almost impossible to manage effectively. The need exists for an effective treatment to control and eliminate PA infection. Past research has shown that if PA infection is treated early, there is a greater likelihood that it may be eliminated completely. This study will examine two treatment regimens to compare which is more effective at eliminating PA infection. In the first regimen, participants ...

This chapter reviews the observations supporting the idea that acute and chronic Pseudomonas aeruginosa infections represent distinct modes of host-pathogen interaction. The virulence factors associated with acute infections and chronic infections are discussed, with a focus on data obtained from human subject-based studies, when possible. P. aeruginosa expresses many virulence factors that can damage host cells and which contribute to infection in both humans and animal models. Ectopic expression of virulence factor regulator (Vfr) in mucA22 strains restored expression of ExoS, type IV pilus (TFP), and elastase, confirming that downregulation of Vfr is responsible for decreased virulence factor expression in mucoid strains under the conditions evaluated in this study. While it is clear that regulators of TFP biogenesis and function are intimately associated with the control of Vfr and cyclic AMP (cAMP) expression, the mechanism that links twitching motility and Vfr remains to be elucidated. rsmZ and
That research had shown that the bacteria "travelled up to 4m and stayed viable for 45 minutes after being coughed into the air," says lead researcher Lidia Morawska in a university press release.. For their experiment, the researchers recruited two individuals- one of whom had cystic fibrosis, and the other of whom had a chronic pseudomonas aeruginosa infection. Airborne cough droplets were collected from both patients, although there was more focus on the patient who was infected.. Despite the droplets of infected saliva quickly losing moisture, contaminated particles remained airborne for quite some time after the infected individual coughed or sneezed, the researchers found. This was particularly the case for larger droplets.. "We found that the concentration of active bacteria in the dried droplets showed rapid decay with a 10-second half-life for most of the bacteria but a subset of bacteria had a half-life of more than 10 minutes," reveals Morawska..

Introduction: Changes in the prevalence of respiratory pathogens in CF may reflect improved therapeutic strategies and clinical practice within a CF centre.. Aims: We hypothesized that active microbiological surveillance and a low threshold for long term nebulised antibiotics might reduce the prevalence of respiratory pathogens in patients with CF.. Methods: Retrospective review of data of patients under full care at a paediatric CF centre in Cardiff between 1998(n=80) and 2011(n=70). We calculated the number of isolates for common pathogens from 1998 onward (expressed as a percentage for each year); mean number of respiratory cultures taken for each patient per year; and the rate of chronic P aeruginosa (Lee 2003) from 2002 onward. Changes in prevalence over time were assesed by linear regression.. Results:Non-significant increase in mean (SD) number of respiratory cultures from 5.3(3.22) to 7.4(2.89) per patient/year.The prevalence of P aeruginosa infection decreased significantly from 43.8% ...
... Aeruginosa lung infection and antibiotic resistance is a growing problem. 'New classes of inhaled
Community acquired pneumonia (CAP) is a major cause of morbidity and mortality worldwide. The contribution of Pseudomonas aeruginosa to both disease burden and antibiotic resistance is unclear; Restrepo et al (European Respiratory Journal 2018;52: 1701190) present a point-prevalence study to address this gap in the data. This multinational study of hospitalised patients investigated the prevalence, risk factors and antibiotic resistance profiles of P. aeruginosa-CAP in 54 countries. A total of 3193 patients were included, all had microbiological testing on admission and had a confirmed diagnosis of CAP. Prevalence of P. aeruginosa-CAP was 4.2 % (133/3193) which represented 11.3 % (133/1173) of all patients with a positive bacterial culture result. Almost half of these patients had an antibiotic-resistant strain (64/133, 48 %; 2.0 % of total cohort) and a quarter had a multi-drug resistant strain of P. aeruginosa (33/133, 25 %; 1.0 % of total cohort).

Throat cultures werent as good this time. She had 2 clean cultures since her first pseudomonas infection last April. I was really hoping for a 3rd clean culture, but luck was not on our side. Her lungs are culturing MRSA, so were going to do a round of bactrum and see if it can eradicate it. The nurse coordinator explained that, just like with the pseudos, they want to try to catch and treat a MRSA infection quickly so it doesnt become a more serious issue and so they can reduce the amount of potential damage it can do to the lungs. I did give her a heads up about Judiths 2 MRSA infections in the abscesses over the summer, just in case they wanted to move to a stronger antibiotic. Since the cultures for the lungs are slightly different than the skin cultures, she said they can still try the bactrum and take it from there. One good point we discovered from the culture is she is still pseudo-free, so at least we dont have to worry about that on top of the MRSA ...
My senior year, he developed an intramuscular sarcoma that appeared very histologically aggressive. He had an entire muscle in his leg removed, a large skin graft, got a Pseudomonas infection, spent a week in the hospital. He was a great patient until you put him in a kennel. He broke out of the ICU and went wandering to find the technician in the night. He developed a slough from extravascular administration of antibiotics in his other front leg and wore two full leg bandages for weeks. In July after graduation and months after surgery, he threw a clot to his front leg and I thought we were toast, but he recovered after 24 hours in the hospital again. He never was aggressive or even resistant to treatment, but by the end of vet school he hated hospitals. I promised him then Id never leave him in one again ...
The philosophy in traditional drug design, i.e., the "one gene, one drug, one disease" paradigm, focuses on the individual properties of a protein, for example, whether the deletion of a gene is lethal to an organism and if it is, then inhibition of the product of the gene by a drug should also be lethal. However, many effective drugs have been found to affect a handful of targets instead of a single protein. Recently, understanding of biological networks and molecule functionality has given rise to a new discipline, network pharmacology, that provides the opportunity to identify new drug targets in an infectious organism, while avoiding targets that cause toxicity in the host. Our group recently combined a genes essentiality and network properties to facilitate the identification of potential drug targets in treating Pseudomonas infection.. ...

Pseudomonas aeruginosa lung infections are a major cause of death in cystic fibrosis and hospitalized patients. Treating these infections is becoming difficult due to the emergence of conventional antimicrobial multiresistance. While monosaccharides have proved beneficial against such bacterial lung infection, the design of several multivalent glycosylated macromolecules has been shown to be also beneficial on biofilm dispersion. In this study, calixarene-based glycoclusters functionalized with galactosides or fucosides have been synthesized. The characterization of their inhibitory properties on Pseudomonas aeruginosa aggregation, biofilm formation, adhesion on epithelial cells, and destruction of alveolar tissues were performed. The antiadhesive properties of the designed glycoclusters were demonstrated through several in vitro bioassays. An in vivo mouse model of lung infection provided an almost complete protection against Pseudomonas aeruginosa with the designed glycoclusters.. ...
Gilead is developing a broad spectrum combination antibiotic (FTI) consisting of fosfomycin (an antibiotic with activity against gram-positive and gram-negative bacteria) and tobramycin (an aminoglycoside antibiotic with potent gram-negative activity) for treatment of patients with CF. FTI offers a potential option for treatment of CF lung infections. It is important to note that the concentration of tobramycin in FTI is lower than that of the approved dose of inhaled tobramycin alone, thereby demonstrating the potential of FTI to minimize long-term toxicity from repeated exposure to aminoglycosides like tobramycin. This study will evaluate the safety and efficacy of 2 dose combinations of fosfomycin/tobramycin for inhalation (FTI), following a 28-day course of Aztreonam for Inhalation (AZLI) in patients with cystic fibrosis and Pseudomonas aeruginosa lung infection ...
Emond et al are reporting in Nat Genetics the identification of DCTN4 as a modifier for P.aeruginosa infection in patients with cystic fibrosis. It is a well-established fact that the majority of patients with cystic fibrosis develop acute and chronic P.aerugonisa infections which are associated with a worse clinical outcome. The authors selected and exome sequenced 91 patients from the EPIC collection with cystic fibrosis and P.aeruginosa and after performing logistic regression adjusted for ancestry and for CFTR mutation risk group identified DCTN4 as the only modifier gene. Dynactin 4 is a component of the dynein-dependent motor that moves autophagosomes along microtubules into lysosomes for degradation as part of the autophagy process which has an essential role in the clearance of P. aeruginosa. The presence of at least one DCTN4 missense variant was significantly associated with both early age of first P. aeruginosaâ€"positive culture and with early age at onset of chronic P. aeruginosa ...

A total of 3,700 Pseudomonas aeruginosa isolates were collected from 17 general hospitals in Japan from 1992 to 1994. Of these isolates, 132 carbapenem-resistant strains were subjected to DNA hybridization analysis with the metallo-beta-lactamase gene (blaIMP)-specific probe. Fifteen strains carrying the metallo-beta-lactamase gene were identified in five hospitals in different geographical areas. Three strains of P. aeruginosa demonstrated high-level imipenem resistance (MIC, , or = 128 micrograms/ml), two strains exhibited low-level imipenem resistance (MIC, , or = 4 micrograms/ml), and the rest of the strains were in between. These results revealed that the acquisition of a metallo-beta-lactamase gene alone does not necessarily confer elevated resistance to carbapenems. In several strains, the metallo-beta-lactamase gene was carried by large plasmids, and carbapenem resistance was transferred from P. aeruginosa to Escherichia coli by electroporation in association with the acquisition of the ...
A total of 183 patients were colonized or infected with multidrug-resistant Pseudomonas aeruginosa isolates at a hospital in Spain during 2007-2010; prevalence increased over this period from 2.8% to 15.3%. To characterize these isolates, we performed molecular epidemiologic and drug resistance analysis. Genotyping showed that 104 (56.8%) isolates belonged to a single major clone (clone B), which was identified by multilocus sequence typing as sequence type (ST) 175. This clone was initially isolated from 5 patients in 2008, and then isolated from 23 patients in 2009 and 76 patients in 2010. PCR analysis of clone B isolates identified the bla(VIM-2) gene in all but 1 isolate, which harbored bla(IMP-22). ST175 isolates were susceptible to only amikacin (75%) and colistin (100%). Emergence of the ST175 clone represents a major health problem because it compromises therapy for treatment of P. aeruginosa nosocomial infections ...

Twenty-three patients (85.2%) were infected with MDR P. aeruginosa, confirmed with cultures and resistance tests, during the ICU stay. In greater part, they were isolated from respiratory and urinary tract infections (33.3% and 25.9%, respectively). Four patients were treated empirically, with 50% of therapy response. The study group presented a mean age of 63 years, 51.9% males, with a mean Acute Physiology and Chronic Health Evaluation II score of 24.63. Sixty-three percent of our patients were first admitted to the hospital with community-acquired infection, none caused by P. aeruginosa. The most frequent cause for ICU admission was communitarian or nosocomial respiratory tract infection (29.9%). The mean time of polimixin B use was 15.59 days. Twelve patients (44%) used imipinem, 12 patients (44%) used teicoplanin and three patients (11%) used vancomicin, for more than 3 days, during the ICU stay before polimixin B use. After treatment with polimixin B, we had 40.7% response and improvement ...
Cyclic-diguanylate (c-di-GMP) is a widespread bacterial signal molecule that plays a major role in the modulation of cellular surface components, such as exopolysaccharides and fimbriae, and in the establishment of a sessile life style. Here, we report that intracellular c-di-GMP levels influence cupA-encoded fimbriae expression in Pseudomonas aeruginosa. In an autoaggregative P. aeruginosa small colony variant (SCV) CupA fimbriae and the intracellular c-di-GMP concentration were found to be enhanced as compared with the clonal wild-type. The SCV morphology and the expression of CupA fimbriae were dependent on a functional PA1120 and morA gene both encoding a GGDEF domain. Overexpression of the GGDEF domain protein PA1120 complemented the PA1120 and the morA mutant with respect to CupA fimbriae expression. In agreement with these findings, overexpression of the EAL domain containing phenotypic variance regulator (PvrR) in the SCV resulted in a decreased intracellular level of c-di-GMP, a reduced ...
Many of the virulence factors produced by the opportunistic human pathogen Pseudomonas aeruginosa are quorum-sensing (QS) regulated. Among these are rhamnolipids, which have been shown to cause lysis of several cellular components of the human immune system, e.g. monocyte-derived macrophages and polymorphonuclear leukocytes (PMNs). We have previously shown that rhamnolipids produced by P. aeruginosa cause necrotic death of PMNs in vitro. This raises the possibility that rhamnolipids may function as a biofilm shieldin vivo, which contributes significantly to the increased tolerance of P. aeruginosa biofilms to PMNs. In the present study, we demonstrate the importance of the production of rhamnolipids in the establishment and persistence of P. aeruginosa infections, using an in vitro biofilm system, an intraperitoneal foreign-body model and a pulmonary model of P. aeruginosa infections in mice. Our experimental data showed that a P. aeruginosa strain, unable to produce any detectable ...

Pseudomonas aeruginosa is an ubiquitous organism. Its ability to survive on minimal nutritional requirements and to tolerate a variety of physical conditions allows its persistence in both community and hospital settings . P. aeruginosa is a serious therapeutic challenge for treatment of both community-acquired and nosocomial infections, due to the ability of this microorganism to develop resistance to multiple classes of antibacterial agents, even during the course of therapy [13, 14]. The increasing frequency of MDR or XDR P. aeruginosa strains is of concern as effective antimicrobial options are limited [15, 16]. Moreover, only a few new antibiotics are currently under development . An increase in MDR bacterial infections among companion animals has been documented in multiple veterinary hospital settings . This is of particular importance due to the risk of transmission to humans and other companion animals in close contact with infected animals, even because in our countries the ...

RESULTS: As a result of the antibiotic resistance analysis, 11 different antibiotypes for Hospital 1 and Hospital 3, while 6 different antibiotypes for Hospital 2 were determined. The highest incidence of MDR strains was observed in Hospital 1. It was found that MDR strains were frequently isolated from patients who underwent surgical interventions or patients in the intensive care units. As a result of genotyping, 9 different genotypes were determined in Hospital 1, 7 in Hospital 2, and 17 in Hospital 3. There was no significant correlation between the antibiotypes and genotypes. A clonal relationship between the MDR strains that were isolated from both the same service and from different services was observed in Hospital 1. These findings support the hypothesis that the strains are spread within the hospital via cross or horizontal transmission through hospital employees or medical instruments. According to Simpsons diversity index, the RAPD-PCR methods discrimination power was found as 0.92 ...

Here, comparative studies of two phenotypic methods using the tube method and the spectrophotometric method for slime production from 100 clinically and 21 environmentally significant isolates of P. aeruginosa were performed. A total of 68 isolates were positive by either of the tests whereas only 34 were positive by both the tests. The tube method detected slime significantly in more number of isolates than the spectrophotometric method. The tube test was found to be superior to the spectrophotometric method in ease of performance, interpretation and sensitivity. Among the clinical isolates, systemic isolates ...

An organism of concern, Pseudomonas aeruginosa is a water-loving bacteria that works and builds biofilms with other threatening bacteria. Understanding that disinfection alone will not rid an engineered water system of bacteria means we need to look toward biofilm-resistant material and disinfection at the source of use as opposed to where the water enters the building.. Antibiotic Resistance of Pseudomonas aeruginosa in Pneumonia at a Single University Hospital Center in Germany over a 10-Year Perioddetermines that "while P. aeruginosa and MDR P. aeruginosa were resistant to a variety of commonly used antibiotics, they were not resistant to colistin in the few isolates recovered from patients with pneumonia.".

Plasma ferritin is an important extracellular iron storage molecule, whose concentration increases drastically in cancer and infection. During infection, the pathogen usurps host iron for its survival and pathogenicity; hence, maintenance of the plasma ferritin level during infection is a crucial host defence mechanism. In this study, the horseshoe crab plasma ferritin complex was purified, characterized, and its involvement in innate immune defence was investigated. The plasma ferritin appears as a 21-kDa subunit on SDS-PAGE. Full-length ferritin-H cDNAs (CrFer-H1 and CrFer-H2) were cloned. Analysis of the 5′ UTR indicates the existence of a functional iron-response element, suggesting that both the CrFer-H genes may be post-transcriptionally regulated. Northern analysis shows that the CrFer-H is ubiquitously expressed. Within 3 h of lipopolysaccharide challenge, the gene is up-regulated by > 12-fold. In contrast, iron-loading did not result in any significant change. When challenged with ...
Author Summary Pathogens face a hostile and often novel environment when infecting a new host, and adaptation to this environment can be critical to a pathogens survival. The genetic basis of pathogen adaptation is in turn important for treatment, since the consistency with which therapies succeed may depend on the extent to which a pathogen adapts via the same routes in different patients. In this study, we investigate adaptation of the bacterium Pseudomonas aeruginosa to laboratory conditions that resemble the lungs of cystic fibrosis patients and to quinolone antibiotics. We find that a handful of genes and genetic pathways are repeatedly involved in adaptation to each condition. Nonetheless, other, less common mutations can play important roles in determining fitness, complicating strategies aimed at reducing the prevalence of antibiotic resistance.
