Escherichia coli (E.coli) is a common bacterium that can be naturally found in the intestinal tract of birds and as result their environment. However, it cause clinical disease called colibacillosis which regarded one most important diseases poultry. Strains E.coli have ability to are described Avian Pathogenic Coli (APEC). Colibacillosis affect all ages different types poultry production inclu...

background: colibacillosis is one of the most economically important diseases of poultry worldwide. objectives: this study was conducted to examine the clonal relatedness and typing of 95 avian escherichia coli isolates by eric-pcr. methods: sixty-three e. coli isolates from two common manifestations of colibacillosis (yolk sac infection and colisepticemia) and 32 isolates from feces of apparen...

background: colibacillosis is one of the most prevalentdiseases in the world that causes multimillion-dollar annuallosses. objectives: in order to evaluate molecular epidemiologyof some virulence associated factors in escherichia coli,isolated from poultry, the presence of iut a, iss, hly f, omp t, iron, afa, sfa (s)and pap g (ii) were investigated by multiplex pcrassay. methods: two hundred th...

BACKGROUND: Colibacillosis is one of the most prevalentdiseases in the world that causes multimillion-dollar annuallosses. OBJECTIVES: In order to evaluate molecular epidemiologyof some virulence associated factors in Escherichia coli,isolated from poultry, the presence of iut A, iss, hly F, omp T, iroN, afa, sfa (S)and pap G (II) were investigated by multiplex PCRassay. METHODS: Two hundred th...

seventy poultry farms’ drinking water was tested for escherichia coli contamination in qom province iniran. the cases of colibacillosis from positive farms were also collected and tested. the isolates wereexamined for serotype, detection of virulence genes by multiplex pcr and antibiotic resistance. thirtypoultry farm water samples were e. coli positive (18.57%), although 13 e. coli isolates we...

Colibacillosis is one of an economically significant disease in the poultry industry, especially for meat breed chickens. Recently it has become a serious problem for layer especially when the birds start laying and also at the later stage of laying. In Japan, the productivity of field laying hens improved when the Δcrp avian colibacillosis live vaccine ("Gall N tect CBL") was used. The surviva...

BACKGROUND The emergence and propagation of different phylogenetic groups of antimicrobial-resistant E. coli have become a worldwide health concern in human and veterinary medicine. Therefore, the evaluation of the phylogenetic distribution of antibiotic-resistant E. coli is important for therapeutic and economic purposes. The aims of this study were to determine phylogenetic groups and pattern...
