Caracterização fenotípica e genotípica de Escherichia coli proveniente de lesões de celulite de frangos de corte

Abstract

Were collected aseptically 40 samples from lesions of chickens from poultry slaughterhouse located in Bahia Recôncavo for phenotypic and genotypic characterization of Escherichia coli. The animals of this research were from four poultry houses located in the same region, weighed 1.050 g 2.867 g 90% were free of pathology associated with cellulitis. Cachexia observed in two chickens, one case of pericarditis and another injured. The weight of the cellulitis lesions ranged from 0.9 to 1.7 g and 85% of these were on the left side of the abdomen of chickens. Escherichia coli was isolated in 82.5% of samples by means of a rapid method for counting by Petrifilm™ plates (3M Company). Was used the Polymerase Chain Reaction (PCR) for verification of the gene of serum resistance (iss), identifying Avian Pathogenic, E. coli (APEC). Iss was detected in 87.9% of isolates. The results of this study showed a clear need for the revision of management in the aviaries, more studies that confirm the presence of APEC in food and its zoonotic potential and the intensification of surveillance in slaughterhouses in order to prevent the emergence and liberation, to consumption of birds with cellulitis lesions.
