We characterized 144 Escherichia coli isolates from severe cellulitis lesions in broiler chickens from South Brazil. Analysis of susceptibility to 15 antimicrobials revealed frequencies of resistance of less than 30% for most antimicrobials except tetracycline (70%) and sulphonamides (60%). The genotyping of 34 virulence-associated genes revealed that all the isolates harbored virulence factors...

The study aims to identify phylogenetic groups and antibiotic susceptibility of poultry Escherichia coli (APEC) isolates. E. was phenotypically biochemically characterized. Isolates from 8/30 (26.66%) liver, 7/30 (23.33%) heart, 4/30 (13.33%) spleen 37-42 days old vaccinated broiler chickens were assessed. Then the isolates (19/90; 21.11%) phylogrouped by quadruplex genotyping based on presence...

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...

Over 30 years, the Asia-Pacific Economic Cooperation has evolved from an informal consultative dialogue into a leading inter-economy forum for promoting open trade and investment, business facilitation, as well economic technical cooperation. The number of APEC economies increased, agenda expanded significantly to include, example, environmental issues, digitalization, social aspects regulation...
