Clostridium difficile has become the most common cause of hospital acquired diarrhea after antibiotic treatment. The aim of this study was to determine the frequency of C. difficile associated diarrhea among hematology/oncology ward patients and to characterize isolated strains. Twenty three toxigenic and thirteen non-toxigenic strains were detected among fecal isolates. Antibiotic susceptibility...
During one year study, 394 stool samples obtained from a random cases of diarrhea were examined for the presence of free shiga-like toxins Stx1 and Stx2 in Vero cells assay. Of 394 stool specimen supernatants tested, 2 (0.5%) gave positive results. The two stool supernatants positive on Vero cell line were wholly capable of being neutralized with the monoclonal antibody to Stx2. Broth cultures of...
This report describes the isolation of Aeromonas veronii biovar sobria as the causative enteropathogen of diarrhoea in an oncological patient after failure of detection of other infectious agents. The case points out the severe and long course of the infection, the diagnostic dilemma, and the prompt recovery after antibiotic treatment.
Diarrhoea, dysentery and other diseases due to other enteric bacteria have reportedly been found to resist chemotherapeutic treatment in some West African communities with fatal consequences in some cases. This study was carried out to determine multidrug resistance patterns of Enterobacteria isolates from processed ready-to-eat foods. Indigenously processed food samples of different types were collected...
Enteropathogenic Escherichia coli strains (EPEC) carrying the eae gene encoding intimin are divided into typical strains producing bundle forming pili, encoded by the bfpA gene, and atypical strains lacking the gene. In the study typical and atypical EPEC that did not agglutinated with EPEC polyvalent antisera but carrying virulence factors characteristic to other pathogenic E. coli i.e. diffusely...
Plants contain a broad spectrum of small molecules with potential antimicrobial properties. Here, we review the antimicrobial activities of plant extracts against enterotoxic bacteria encoding AB5 toxins, including Vibrio cholerae, Shigella dysenteriae and enterotoxic Escherichia coli strains. Several plant extracts have strong antimicrobial effects and the potential to boost Oral Rehydration Therapy,...
