Background: Escherichia coli (E. coli) is one of the most important infectious agents in patients undergoing prostate biopsy. It belongs to a large family of gram-negative rods, Enterobacteriaceae. This family includes members of the normal flora of the intestine that are only occasionally pathogenic. Recent considerations of rectal colonization with fluoroquinolone-resistant E. coli shows the ...

to determine the contamination of traditional cheeses to e. coli o157:h7 this study was conducted in chaharmahal and bakhtiari province. two hundred cheeses samples were obtained randomly and bacteriological examinations were done on all isolates, by culture in selective enrichment media and after that, selective plating. suspected colonies were examined with o and h antisera for identification...

shiga toxin-producing escherichia coli (stec) are food-borne pathogens primarily associated with the consumption of contaminated ground beef and are an important food safety concern worldwide. stec has been found to produce a family of related cytotoxins known as shiga toxins (stxs). shiga toxins have been classified into two major classes, stx1 and stx2. a single strains of stec can produce st...

In this study, to know about the phylogeny of Escherichia coli isolated from broilers with collibacillosis in Tabriz, 70 E. coli isolates recovered from broilers with collibacillosis were characterized for phylogenetic group (A, B1, B2, D) by multiplex PCR. Of the all 70 samples, 35 (50%) isolates were classified as type A, 32 (45%) as type D, 2 (2.8%) as type B1 and 1 (2.8%) as type B2. This s...

This study was designed to compare the efficacy of a phytobiotic containing a mixture of essential oils of Oreganum aetheroleum and an antibiotic containing ciprofloxacin as an active principle for the treatment of experimental Escherichia coli (E. coli) infection in broiler chickens. Two-hundred-day-old broiler chickens were divided into 5 equal groups. The 1st group was neither challenged nor...

the present study was conducted to detect the occurrence, serotype, genotype, phylogenetic relationship and antimicrobial resistance pattern of stec from healthy goats of west bengal, india. from the 125 faecal samples collected from healthy goats, 245 isolates were identified as escherichia coli. the e. coli harbouring any gene for shiga toxins (stx1/stx2) was detected in 36 (14.7%) of the 245...

background and objectives: diarrhea is one of the most prevalent diseases in the world, specially in developing countries. one of the most important causative agents of bacterial diarrhea is diarrheagenic escherichia coli (dec) which causes gastroenteritis and this group involving enterotoxigenic e. coli (etec), enteropathogenic e. coli (epec), enteroaggregative e. coli (eaec), enterohemoragic ...
