The intimin gene eae, located within the locus of enterocyte effacement pathogenicity island, distinguishes enteropathogenic Escherichia coli (EPEC) and some Shiga toxin-producing E. coli (STEC) strains from all other pathotypes of diarrheagenic E. coli. EPEC is a leading cause of infantile diarrhea in developing countries, and intimin-positive STEC isolates are typically associated with life-t...

Mutations in the epsilon-acetylcholine receptor (AChR-epsilon) subunit gene cause congenital myasthenic syndromes (CMS) with postsynaptic neural transmission defects. The authors present 3 male and 2 female patients from three unrelated Croatian, Hungarian, and Russian families with autosomal recessive CMS. All patients manifested with variable degrees of ophthalmoparesis and generalized, fatig...

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...

the present investigation was conducted to study the effects of experimental clostridium perfringens type d enterotoxaemia in teddy goats. clinical signs started to appear after 30 min of experimental infection like anorexia, diarrhea, dehydration, frothing and dyspnea. gross lesions consisted of severe congestion in tissues of varying intensity with enlarged mesenteric lymph nodes while histol...

Specific globin mRNA accumulation was quantitated in several lines of K562 cells in the absence and the presence of hemin. Using specific cloned DNA probes, the amounts of zeta, alpha, epsilon and gamma mRNAs were shown to be increased 2-3-fold in the presence of 20 microM hemin. No delta- or beta-globin mRNAs were detectable in any of the lines. In one line, Bos, there was a marked decrease in...
