Reference

The study aimed to investigate the antibiotic susceptibility of commensal E. coli, especially towards antimicrobials used in human therapy, isolated in organic, antibiotic-free and conventional (C) broilers on farms and at slaughter. The diffusion of ESBL E. coli was also assayed.

A total of 174 strains were collected from samplings performed on conventional (C), organic (O) and antibiotic-free (AF) chicken farms (cloacal swabs and environmental samples) and at slaughter (caecal contents and skin samples). In particular, 58 strains of E. coli were collected for each typology of farming: in C (25 and 33 on farm and in slaughterhouse, respectively), in O (31 and 27 on farm and in slaughterhouse, respectively) and in AF (25 and 33 on farm and in slaughterhouse, respectively).
