activity of a dry mist hydrogen peroxide system against environmental clostridium difficile contamination in elderly care wards.clostridium difficile causes serious healthcare-associated infections. infection control is difficult, due in part to environmental contamination with c. difficile spores. these spores are relatively resistant to cleaning and disinfection. the activity of a dry mist hydrogen peroxide decontamination system (sterinis) against environmental c. difficile contamination was assessed in three elderly care wards. initial sampling for c. difficile was performed in 16 rooms across a variety of wards and ...200818694613
gastric acid suppression by proton pump inhibitors as a risk factor for clostridium difficile-associated diarrhea in hospitalized patients.evidence for the association between clostridium difficile (c. difficile) and the use of proton pump inhibitor (ppi) is unclear. this study investigated the relationship between clostridium difficile-associated diarrhea (cdad) and exposure to acid suppressive therapy in hospitalized adult patients while controlling for the most common predisposing risk factors.200818702653
combination therapy with direct hemoperfusion using polymyxin b-immobilized fiber and oral vancomycin improves fulminant pseudomembranous colitis by reducing the elevated endogenous cannabinoids and inflammatory cytokines: report of a case.this paper reports a case of fulminant pseudo-membranous colitis which did not lead to septic shock. the case was improved by combination therapy with direct hemoperfusion using polymyxin b-immobilized fiber and oral vancomycin. direct hemoperfusion using polymyxin b-immobilized fiber has been demonstrated to have excellent therapeutic effects for the treatment of septic shock by removing circulating lipopolysaccharide. in the present case, the combination therapy dramatically improved clinical ...200818705306
benefit-risk assessment of linezolid for serious gram-positive bacterial infections.linezolid is an oxazolidinone, a new class of antibacterial with a unique mechanism of action, namely inhibition of the formation of a functional 70s initiation complex in the 50s bacterial ribosomal subunit. linezolid is highly active against multidrug-resistant gram-positive cocci, including meticillin-resistant staphylococcus aureus (mrsa), vancomycin-intermediate and vancomycin-resistant s. aureus, and vancomycin-resistant enterococci; its spectrum of activity also includes some anaerobic ba ...200818707190
molecular characterization of a clostridium difficile bacteriophage and its cloned biologically active endolysin.clostridium difficile infection is increasing in both frequency and severity, with the emergence of new highly virulent strains highlighting the need for more rapid and effective methods of control. here, we show that bacteriophage endolysin can be used to inhibit and kill c. difficile. the genome sequence of a novel bacteriophage that is active against c. difficile was determined, and the bacteriophage endolysin gene was subcloned and expressed in escherichia coli. the partially purified endoly ...200818708505
infection control and prevention in perioperative practice.the personal and financial consequences of avoidable infection are enormous in personal and global terms (dh 2003, stone, larson & kawar 2002). patients expect to be treated and cared for in clean conditions, and not be exposed to the risks of acquiring an infection by poor practice on the part of healthcare workers (dh 2005, health care commission 2005). infection control and prevention in perioperative settings assumes an even greater significance because of the vulnerability of patients who a ...200818710124

clostridium difficile: a reemerging pathogen.clostridium difficile is an important health care-associated pathogen, especially among older adults who are disproportionately affected by c difficile infection (cdi). during the current decade, there has been a dramatic increase in the incidence and severity of health care-associated cdi. these clinically relevant changes are temporally associated with the emergence of a hypervirulent strain of c difficile that has now become widely disseminated. the increased burden of disease and incidence o ...200818763846
clathrin-independent endocytosis of erbb2 in geldanamycin-treated human breast cancer cells.the epidermal growth factor (egf)-receptor family member erbb2 is commonly overexpressed in human breast cancer cells and correlates with poor prognosis. geldanamycin (ga) induces the ubiquitylation, intracellular accumulation and degradation of erbb2. whether ga stimulates erbb2 internalization is controversial. we found that erbb2 was internalized constitutively at a rate that was not affected by ga in sk-br-3 breast cancer cells. instead, ga treatment altered endosomal sorting, causing the tr ...200818765569
comparison of oritavancin versus vancomycin as treatments for clindamycin-induced clostridium difficile pcr ribotype 027 infection in a human gut model.to compare the efficacy of oritavancin and vancomycin in the treatment of clostridium difficile infection (cdi) using an in vitro human gut model.200818772161
absence of pseudomembranes in clostridium difficile-associated diarrhea in patients using immunosuppression agents.clostridium difficile is a major cause of diarrhea in hospitalized patients. although pseudomembranes are crucial evidence for diagnosis of c. difficile-associated diarrhea (cdad), some cases do not show any pseudomembranes. the aim of this study was to verify the hypothesis that pseudomembranes are not generated in immunosuppressed patients because of the absence of immunoreactions.200918781540
comparison of three commercial methods for rapid detection of clostridium difficile toxins a and b from fecal specimens.three rapid enzyme immunoassays (x/pect clostridium difficile toxin a/b test, wampole tox a/b quik chek, and immunocard toxins a&b) were compared for the diagnosis of clostridium difficile infection. of the 367 stool specimens tested, 102 (27.8%) were positive for toxigenic c. difficile when a combination of direct cytotoxicity assay and cytotoxic culture was used as the gold standard. sensitivity/specificity values were 49.0%/95.8%, 54.9%/95.5%, and 66.7%/95.1%, respectively. the median times t ...200818784313
nonutility of repeat laboratory testing for detection of clostridium difficile by use of pcr or enzyme immunoassay.the diagnostic gains of repeat testing for clostridium difficile by enzyme immunoassay and pcr (i.e., initial negative result followed by positive result) within a 7-day period were 1.9 and 1.7%, respectively. there is little value of repeat testing for c. difficile by enzyme immunoassay or pcr.200818784320

antibiotic-associated diarrhea: epidemiology, trends and treatment.a common complication of antibiotic use is the development of gastrointestinal disease. this complication ranges from mild diarrhea to pseudomembranous colitis. outbreaks of antibiotic-associated diarrhea (aad) may also occur in healthcare settings, usually caused by clostridium difficile. aad typically occurs in 5-35% of patients taking antibiotics and varies depending upon the specific type of antibiotic, the health of the host and exposure to pathogens. the pathogenesis of aad may be mediated ...200818811240
evaluation of the risks of shedding salmonellae and other potential pathogens by therapy dogs fed raw diets in ontario and alberta.dogs that participate in animal-assisted interventions (aais), often called 'therapy dogs', commonly interact with humans whose immune systems are not functioning optimally. the advisability of feeding raw meat (including poultry) to these animals remains a highly contentious issue, in spite of increasing evidence that raw meat is frequently contaminated with salmonella. we set out to determine if consuming raw meat influences the risk of therapy dogs shedding salmonella and other pathogens. two ...200818811908
mechanisms of infectious diarrhea.infectious diarrhea is an important public health problem worldwide. research has provided new insights into the mechanisms of diarrhea caused by various pathogens that are classified as noninflammatory, inflammatory or invasive. these three groups of organisms cause two diarrheal syndromes--noninflammatory diarrhea and inflammatory diarrhea. the noninflammatory diarrheas are caused by enterotoxin-producing organisms such as vibrio cholerae and enterotoxigenic escherichia coli, or by viruses tha ...200818813221
contamination of hospital curtains with healthcare-associated pathogens.in a culture survey, we found that 42% of hospital privacy curtains were contaminated with vancomycin-resistant enterococci, 22% with ethicillin-resistant staphylococcus aureus, and 4% with clostridium difficile. hand imprint cultures demonstrated that these pathogens were easily acquired on hands. hospital curtains are a potential source for dissemination of healthcare-associated pathogens.200818823274
[comparison of three enzyme immunoassays for detection of clostridium difficile toxins a and b].diagnosis of clostridium difficile-associated diarrhea is classically based on detection of toxin a and/or toxins a+b by using several techniques. however, these techniques show important differences in terms of sensitivity and specificity. in this work, we compared three commercial immunoenzymatic tests for detecting c. difficile toxins.200818824307
melanin-concentrating hormone (mch) modulates c difficile toxin a-mediated enteritis in mice.melanin-concentrating hormone (mch) is a hypothalamic orexigenic neuropeptide that regulates energy balance. however, the distribution of mch and its receptor mchr1 in tissues other than brain suggested additional, as yet unappreciated, roles for this neuropeptide. based on previous paradigms and the presence of mch in the intestine as well as in immune cells, its potential role in gut innate immune responses was examined.200918824554
deaths from norovirus among the elderly, england and wales.the number of deaths in england and wales associated with gastrointestinal pathogens, norovirus in particular, in persons >or=65 years was estimated for 2001-2006. regression analysis was used to model monthly counts of gastrointestinal pathogens in fecal samples from infected patients against monthly counts of deaths from infectious and noninfectious intestinal diseases. data came from the office of national statistics (death registrations from local registrars) and from the health protection a ...200818826817
who's winning the war?traditionally, methicillin-resistant staphylococcus aureus (mrsa) has been seen as an infection control problem in healthcare communities. it is now clear that antibiotic use is also an important factor in the control of mrsa, both in the treatment of infection and also, paradoxically perhaps, as a cause of the mrsa problem, in the same way that antibiotic use causes clostridium difficile disease. at both levels, major improvements in the quality of our antibiotic use are required, particularly ...200818829723

clostridium difficile colitis: wash your hands before stopping the proton pump inhibitor.proton pump inhibitors (ppis) have revolutionized the management of acid-related disorders. the potential adverse effects related to ppi use fall into four main categories: idiosyncratic reactions, drug-drug interactions, drug-induced reflex hypergastrinemia, and drug-induced hypochlorhydria. clostridium difficile (c. difficile) colitis, an epidemic of major importance among hospitalized individuals, is potentially facilitated by the fourth mechanism in ppi users. this article interprets the res ...200818924259
distribution and antimicrobial susceptibility patterns of clostridium difficile pcr ribotypes in english hospitals, 2007-08.a surveillance study designed to provide a representative sample of the strains of clostridium difficile causing infections in hospitals in england was in operation from april 2007 to the end of march 2008. six hundred and seventy-seven isolates were obtained from 186 hospitals in the nine geographical regions of england as recognised by the health protection agency's regional microbiology network. typing studies revealed that pcr ribotype 027 is now the most common strain isolated from symptoma ...200818926105
ozone gas is an effective and practical antibacterial agent.bacterial infections continue to pose a threat to health in many institutional and communal settings, and epidemics are frequent. current control measures are clearly inadequate; thus, there is a need for a simple, effective, and safe way to decontaminate surfaces.200818926308
characterization of clostridium difficile isolates using capillary gel electrophoresis-based pcr ribotyping.we have developed a clostridium difficile pcr ribotyping method based on capillary gel electrophoresis and have compared it with conventional pcr ribotyping. a total of 146 c. difficile isolates were studied: five isolates were reference strains (pcr ribotypes 001, 014, 017, 027 and 053); 141 were clinical isolates comprising 39 austrian pcr ribotypes collected in the period 2006-2007 at 25 austrian healthcare facilities. capillary gel electrophoresis yielded up to 11 fragments per isolate and 4 ...200818927415
probiotics in allergy management.the gut contains a diverse bacterial flora that is acquired at birth and has a number of physiological functions. administration of prebiotics or probiotics may favourably alter this gut microflora. prebiotics are poorly digested oligosaccharides that promote the growth of desirable bacteria and may have other beneficial gastrointestinal and systemic effects. probiotics are "helpful" human bacteria that provide a variety of health benefits when administered exogenously. probiotics produce benefi ...200818931598
mass spectrometric analysis of the s-layer proteins from clostridium difficile demonstrates the absence of glycosylation.like many other bacterial cell surfaces, the cell wall of clostridium difficile is also encapsulated by a proteinaceous paracrystalline layer, the surface (s)-layer. in many bacterial species, the s-layer proteins (slps) have been shown to be glycosylated, whereas in other species glycosylation is absent. unusually, the s-layer of c. difficile is composed of two distinct proteins, the high-molecular weight (hmw) and low-molecular-weight (lmw) slps. previous investigations have reported that one ...200918932172
regulation of kir2.1 channels by the rho-gtpase, rac1.mutations in kir2.1 inwardly rectifying potassium channels are associated with andersen syndrome, a disease characterized by potentially fatal cardiac arrhythmias. while several andersen-associated mutations affect membrane expression, the cytoplasmic signals that regulate kir2.1 trafficking are poorly understood. here, we investigated whether the rho-family of small gtpases regulates trafficking of kir2.1 channels expressed in hek-293 cells. treatment with clostridium difficile toxin b, an inhi ...200918932198

meta-analysis to assess risk factors for recurrent clostridium difficile infection.summary: clostridium difficile infection (cdi) is the most common cause of hospital-acquired diarrhoea. it is estimated that 15-20% of patients experience recurrence of cdi. a limited number of studies have looked at the risk factors for recurrent cdi. we conducted a meta-analysis of observational studies and randomised controlled trials (rcts) to assess risk factors for recurrent cdi. studies were identified using the pubmed database and search terms 'clostridium difficile associated diarrhoea' ...200818951661
porcine circovirus 2 infection of epithelial cells is clathrin-, caveolae- and dynamin-independent, actin and rho-gtpase-mediated, and enhanced by cholesterol depletion.epithelial cells are the major in vivo target cells for porcine circovirus type 2 (pcv2). although these cells are used for most studies of pcv2 gene expression and, little is known on pcv2 entry, attachment and internalization, in epithelial cells. pcv2 attachment to epithelial cells occurred rapidly and in a time-dependent manner. in contrast to attachment, internalization was slow. immunofluorescent stainings revealed that during internalization, pcv2 co-localized with clathrin, but not caveo ...200918952130
