Co-relationship between Escherichia coli in broiler cellulitis and liver lesions

Abstract Pathogenic strains of Escherichia coli may invade the subcutaneous tissue poultry and cause cellulitis, whilst pathogen also lesions in internal organs such as liver. Current paper co-relates virulence genes characteristic Avian (APEC) broilers´ cellulitis liver lesions. One hundred carcasses were retrieved from production chain an avian abattoir state Bahia, Brazil, between August 2013 January 2014, due to detection Cellulitis samples aseptically quantify E. by Petrifilm™ count fast method (3M Company) (AOAC 998.8). Virulent iss iutA removed isolates Polymerase Chain Reaction (PCR). was isolated 82.0% broilers bacterium concomitantly detected 40.0% broilers. counts ranged 1.00 4.73 log CFU/g 2.00 9.00 UFC/g 97.56% 89.02% isolates, respectively. Genotype analysis demonstrated concomitant amplification 60.0% (n=40) which simultaneous isolation occurred. There a positive significant co-relationship (r=0.22; p<0.05) variables occurrence co-relationships populations (r=0.46; when detected. Since results showed relationship possible systemic infection, criterion for total discarding carcass be suggested.
