Serogroups and virulence genes of escherichia coli isolated from psittacine birds among avian pathogenic e coli (apec) the prevalence of p fimbriae varied between 18 to 30% (janben et al 2001, delicato et al 2003) the role of p fimbriae in the pathogenesis of avian colibacillosis is still controversial, but the expression of p. Prevalence of escherichia coli carrying extended-spectrum -lactamases (ctx-m and tem-52) from broiler chickens and turkeys in great britain between 2006 and 2009 23 november 2010 | journal of antimicrobial chemotherapy, vol 66, no 1.
Prevalence and relatedness of escherichia coli o157:h7 strains in the feces and on the hides and carcasses of us meat goats at slaughter molecular and antimicrobial susceptibility analyses distinguish clinical from bovine escherichia coli o157 strains. Three hundred (300) samples of fresh raw chicken, beef, goat and pork meat were screened for arcobacter species by selective cultural procedures and for escherichia coli, salmonella species and staphylococcus aureus enriched in peptone water and then streaked onto appropriate bacteriological agar. Global widespread of extended-spectrum β-lactamase (esbl)-producing enterobacteriaceae, especially escherichia coli poses a greater threat in healthcare and community settings of humans raw meats from food animals colonized with esbl producers may be one of important transmission routes for those bacteria in the community. The work was aimed to study prevalence of escherichia coli contamination in fish and shrimp sold in retail markets at kolkata, india in different seasons e coli was identified by standard microbiological, biochemical tests, and further confirmed by 16s rrna pcrthe faecal coliform loads in fish and shrimp samples were assessed.

Escherichia coli (e coli) is a gram-negative, facultative anaerobic, rod-shaped bacterium that is commonly found in the lower intestine of warm-blooded animals. The gram-negative bacteria e coli o157:h7 and other enterohemorrhagic e coli (ehec) typically cause acute bloody diarrhea, which may lead to hemolytic-uremic syndrome symptoms are abdominal cramps and diarrhea that may be grossly bloody.
