aim : in this study, the prevalence of c. difficile , from patients with gastrointestinal complaints and its association with other enteropathogen microbes were investigated. background : clostridium difficile is an important pathogen associated with outbreaks of pseudomembranous colitis and other intestinal disorders, such as diarrhea. patients and methods : enterotoxin and cytotoxin (toxin a ...

When axenic mice fed a commercial diet were monoassociated with two toxigenic strains of Clostridium difficile, 100% of them died 3 days after inoculation and both enterotoxin and cytotoxin were produced in their intestinal tract. However, when axenic mice were fed various semisynthetic diets before C. difficile challenge, some of them survived and their fecal cytotoxin and enterotoxin producti...

Background & Aims: Clostridium difficile has been identified as a pathogen in antibiotic associated diarrhea (AAD), pseudomembranous colitis and also nosocomial diarrhea. The present study was performed to find the prevalence of toxigenic strains of C .difficile isolated from diarrhea patients hospitalized in Tehran hospitals. Method: A total of 98 fecal samples obtained during July to December...

OBJECTIVE The objective of this study was to detect C. difficile in patients presenting with Antibiotic Associated Diarrhoea. METHODS Stool samples from twenty-five patients collected over a period of four months were processed for C. difficile by culture and the isolates were identified following standard methods. C. difficile toxins A and B and C. perfringens enterotoxin were detected by EL...

The prevalence of Clostridium difficile infections in HIV-positive patients with regard to the presence of its enterotoxin was investigated. Enzyme immunoassay (EIA, Meridian Diagnostic Inc) was used for the detection of C. difficile enterotoxin in stool specimens collected from 201 HIV-positive and 271 HIV-negative diarrheal patients. Culture was performed on cycloserine cefoxitin fructose aga...

Some pathogenic spore-forming bacilli employ a binary protein mechanism for intoxicating the intestinal tracts of insects, animals, and humans. These Gram-positive bacteria and their toxins include Clostridium botulinum (C2 toxin), Clostridium difficile (C. difficile toxin or CDT), Clostridium perfringens (ι-toxin and binary enterotoxin, or BEC), Clostridium spiroforme (C. spiroforme toxin or C...

Faecal samples from 37 patients with cystic fibrosis and 40 control patients at the Brompton Hospital and the London Chest Hospital were examined for the presence of Clostridium difficile. The organism was isolated from 2 (17%) of control patients who were receiving antibiotics and from one (3.6%) of control patients who had no antimicrobial treatment. Thirty two per cent of the patients with c...

AIM In this study, the prevalence of C. difficile, from patients with gastrointestinal complaints and its association with other enteropathogen microbes were investigated. BACKGROUND Clostridium difficile is an important pathogen associated with outbreaks of pseudomembranous colitis and other intestinal disorders, such as diarrhea. PATIENTS AND METHODS Enterotoxin and cytotoxin (toxin A and...

AND EXPLANATION OF THE TEST Toxigenic Clostridium difficile is the leading cause of nosocomial infectious diarrhea in developed countries. An estimated 300,000 cases of C. difficile associated disease (CDAD) are seen per year in U.S. hospitals alone. 2 Clostridium difficile is the etiologic agent in approximately 25% of all cases of antibiotic-associated diarrhea. Virtually any antibiotic can p...

introduction: toxigenic clostridium difficile is the major cause of antibiotic-associated diarrhea, colitis, and pseudomembranous colitis. the pathogenicity of c. difficile is related to toxins a&b.; children with cancer are at risk of developing c. difficile infection (cdi) due to increased exposure to antibiotics, immunosuppression, and longer hospital stays. recently, due to higher sensitivit...
