The aim of this study was to fortify the clinical importance and representation of toxigenic and non-toxigenic Clostridium difficile isolated from stool samples of hospitalized patients. This survey included 80 hospitalized patients with diarrhea and positive findings of Clostridium difficile in stool samples, and 100 hospitalized patients with formed stool as a control group. Bacteriological e...
Identification of a Prepore Large-Complex Stage in the Mechanism of Action of Clostridium perfringens Enterotoxin James G. Smedley III, Francisco A. Uzal, and Bruce A. McClane* Department of Molecular Genetics and Biochemistry and Molecular Virology and Microbiology Graduate Program, University of Pittsburgh School of Medicine, Pittsburgh, Pennsylvania, and California Animal Health and Food Saf...
We report here a draft genome sequence of Clostridium botulinum Adk2012 responsible for a foodborne botulism case that occurred in Tottori, Japan, in 2012. Its genome size was 2,904,173 bp, with 46 rRNAs and 54 tRNAs, at a coverage of 14.5×.
Clostridium difficile PCR ribotype 018 has emerged in Italy, South Korea, and Japan, causing severe infections and outbreaks. In this study, we sequenced the genome of IT1118, an Italian clinical isolate, to clarify the molecular features contributing to the success of this epidemic type.
Clostridium difficile, belonging to ribotype 018 (RT018), is one of the most prevalent genotypes circulating in hospital settings in Italy. Here, we report the draft genome of C. difficile CD8-15 belonging to RT018, isolated from a patient with fatal C. difficile-associated infection.
Previous work indicated that Clostridium perfringens gerKA gerKC spores germinate significantly, suggesting that gerKB also has a role in C. perfringens spore germination. We now find that (i) gerKB was expressed only during sporulation, likely in the forespore; (ii) gerKB spores germinated like wild-type spores with nonnutrient germinants and with high concentrations of nutrients but more slow...
شناسایی و بررسی حساسیت آنتی بیوتیکی باکتری های جداشده از مدفوع سگ های سالم و مبتلا به اسهال در شیراز
, In this study 77 and 86 bacterial strains were isolated from faeces of healthy and diarrhoeic dogs respectively. All Salmonella isolates were confirmed by peR method using specific invA genes. Antibacterial activity of 8 routine antibiotics including tylosin, gentamycin, kanamycin, neomycin, tetracycline, oxytetracycline, chloramphenicol and sulfadiazine on the isolated bacteria was evaluated...
Several different nomenclatures have been applied to the Clostridium difficile toxins and their associated genes. This paper summarizes the new nomenclature that has been agreed to by the research groups currently active in the field. The revised nomenclature includes C. difficile toxins and other related large clostridial toxins produced by Clostridium sordellii and Clostridium novyi, and corr...
The incidence and severity of Clostridium difficile colitis has markedly increased in recent years. The spectrum of Clostridium difficile infection ranges from asymptomatic colonization to fulminant colitis requiring immediate surgery. Medical therapy failure and the presence of toxic megacolon dictate urgent surgical treatment with unfortunate high mortality rates (35% to 57%). We broach herei...
