Virulence and antibiotic resistance profile of avian Escherichia coli strains isolated from colibacillosis lesions in central of Algeria

Avian pathogenic cause extensive mortality in poultry flocks, leading to extensive economic losses. To date, in Algeria, little information has been available on virulence potential and antibiotics resistance of avian isolates. Therefore, the aim of this study was the characterization of virulence g...

Description
Summary:Avian pathogenic cause extensive mortality in poultry flocks, leading to extensive economic losses. To date, in Algeria, little information has been available on virulence potential and antibiotics resistance of avian isolates. Therefore, the aim of this study was the characterization of virulence genes and antibiotic resistance profile of Algerian strains isolated from diseased broilers. In this study, 43 avian strains isolated from chicken colibacillosis lesions at different years were analyzed to determine their contents in 10 virulence factors by polymerase chain reaction, antimicrobial susceptibility to 22 antibiotics belonging to six different chemical classes and genomic diversity by pulsed-field gel electrophoresis (PFGE). Mainly isolates (58.1%) carried two at six virulence genes and the most frequent virulence gene association detected were T (protectin), F (hemolysin) with 55.8% (p
