Distribution of virulence associated genes in isolated Escherichia coli from avian colibacillosis
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...
متن کاملEfficacy of an avian colibacillosis live vaccine for layer breeder in Japan
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...
متن کاملIn vitro assessment of pathogenicity and virulence encoding gene profiles of avian pathogenic Escherichia coli strains associated with colibacillosis in chickens
Background: Avian pathogenic Escherichia coli (APEC) strains have been associated with various disease conditions in avian species due to virulence attributes associated with the organism. Aims: This study was carried out to determine the in vitro pathogenic characteristics and virulence encoding genes found in E. coli strains associated with colibacillosis in chickens. Methods: Fifty-two stock...

متن کاملOccurrence of purulent mandibular and maxillary osteomyelitis associated with Pseudomonas aeruginosa in a sheep flock in south-west of Iran
This report describes an outbreak of purulent mandibular and/or maxillary osteomyelitis caused by Pseudomonas aeruginosa in a sheep flock located in the Khuzestan province, Iran. Jaw bones of almost 100 out of 500 mature sheep in a flock became severely deformed with a variably sized firm swelling, without any signs of inflammation in the surrounding soft tissues. The affected animals showed an...
