Antimicrobial susceptibilities of exfoliative toxigenic and non-toxigenic Staphylococcus hyicus strains in Japan.
Staphylococcus hyicus isolates (n=207), including 150 exfolitative toxigenic and 57 non-toxigenic strains, were examined for their susceptibility to 13 antimicrobial agents by using the dehydrated 96-well MIC panel system. The frequency of their resistance to penicillin and ampicillin was 76.8% (159/207), followed by erythromycin (56%, 116/207), trimethoprim-sulfamethoxazole (28.5%, 59/207), ch...
متن کاملIdentification of toxigenic Clostridium difficile by counterimmunoelectrophoresis.
A counterimmunoelectrophoresis (CIE) technique which reacted positively with culture filtrates of Clostridium difficile was developed and compared with a cytotoxicity assay in human embryonic lung cell cultures. CIE, employing C. sordellii antitoxin, detected 17 of 17 C. difficile strains. Of those positive by CIE, 13 were cytotoxic in cell culture. Fourteen Clostridium species other than C. di...
متن کاملCommunity Environmental Contamination of Toxigenic Clostridium difficile
BACKGROUND Clostridium difficile infection is often considered to result from recent acquisition of a C difficile isolate in a healthcare setting. However, C difficile spores can persist for long periods of time, suggesting a potentially large community environmental reservoir. The objectives of this study were to assess community environmental contamination of toxigenic C difficile and to asse...
متن کاملClinical importance and representation of toxigenic and non-toxigenic Clostridium difficile cultivated from stool samples of hospitalized patients
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...
متن کاملHorizontal gene transfer converts non-toxigenic Clostridium difficile strains into toxin producers
Clostridium difficile is a major nosocomial pathogen and the main causative agent of antibiotic-associated diarrhoea. The organism produces two potent toxins, A and B, which are its major virulence factors. These are chromosomally encoded on a region termed the pathogenicity locus (PaLoc), which also contains regulatory genes, and is absent in non-toxigenic strains. Here we show that the PaLoc ...
