use of acid suppression medication is associated with risk for c. difficile infection in infants and children: a population-based study.acid suppression medication is associated with clostridium difficile infection (cdi) in adults and is increasingly prescribed to children. this study evaluated the relationship between acid suppression medication and incident cdi in children.201526060292
comparative genomic and phenomic analysis of clostridium difficile and clostridium sordellii, two related pathogens with differing host tissue preference.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.201526059449
risk factors for surgical site infection in laryngeal cancer surgery.surgical site infection (ssi) is a significant factor of morbidity and mortality in patients surgically treated for laryngeal carcinoma. the aim of this prospective study in 277 patients was to determine the incidence of ssi in patients surgically treated for laryngeal squamous cell carcinoma and to identify risk factors for development of ssi. patients with previous chemotherapy and/or radiotherapy were excluded. all patients had tracheostomy postoperatively and received antibiotic prophylaxis ...201526058244
clinical and epidemiologic considerations of clostridium difficile in harbor seals (phoca vitulina) at a marine mammal rehabilitation center.between 1998 and 2008, 15 cases of segmental to diffuse hemorrhagic to necrohemorrhagic enterocolitis were diagnosed in neonatal and weaned juvenile harbor seals (phoca vitulina) presented from the vancouver aquarium marine mammal rescue centre for rehabilitation. based on a combination of gross pathology, histopathology, bacterial isolation, and toxin testing, clostridium difficile enterocolitis was diagnosed. most pups were anorexic or inappetant and died acutely with few other premonitory sig ...201526056868
impact of vancomycin faecal concentrations on clinical and microbiological outcomes in clostridium difficile infection.to assess the impact of faecal vancomycin concentrations on clinical and microbiological outcomes in patients with clostridium difficile infection (cdi) and whether these concentrations vary with stool consistency and frequency, faecal concentrations of vancomycin were measured in stools collected at various times from patients initiated on 125mg every 6h (q6h) for 10 days. stool consistency and frequency were determined over the course of therapy. clinical and microbiological outcomes were asse ...201526055927
mode of action and bactericidal properties of surotomycin against growing and nongrowing clostridium difficile.surotomycin (cb-183,315), a cyclic lipopeptide, is in phase 3 clinical development for the treatment of clostridium difficile infection. we report here the further characterization of the in vitro mode of action of surotomycin, including its activity against growing and nongrowing c. difficile. this was assessed through time-kill kinetics, allowing a determination of the effects on the membrane potential and permeability and macromolecular synthesis in c. difficile. against representative strain ...201526055381
