Prevalence of virulence genes in Escherichia coli isolates from poultry farms in Northeastern Brazil
ABSTRACT: In this study, 35 E. coli isolates obtained from broiler chickens and commercial laying hens from farms in the state of Pernambuco were analyzed. Through PCR analysis, the number of isolates showing amplification for the tested virulence factors were as follows: iss (16), iutA (10), hlyF (18), iroN (11), ompT (16), fimA (14), tsh (5), papA (2), crl (20), csgA (0), and iucA (4). Twenty eight isolates amplified more than one of the tested genes in different patterns, and they were phylogenetically classified into groups A (71.42%) and B1 (28.57%). Thus, the detection of virulence genes in the isolates indicated an association with more significant respiratory conditions and extra-intestinal diseases.
