PREVALENCE OF POULTRY ESCHERICHIA COLI ISOLATES PRODUCING EXTENDED-SPECTRUM BETA-LACTAMASES AND THEIR PUBLIC HEALTH IMPORTANCE

Abstract

Recently, different reports highlighted the problem with dissemination of Escherichia coli producing extended spectrum beta-lactamases (ESBL) in poultry farms in Europe. The high incidence of Escherichia coli among poultry in Europe harbouring blaCTX-M-1 and the occurrence of ESBL and AmpC-producing Escherichia coli in raw meat samples collected from slaughterhouses in Europe have been discussed. ESBL-producing Enterobacteriaceae can be transmitted along the broiler production chain. Plasmids responsible for ESBL production frequently carry genes coding resistance to other antimicrobial classes, such as fluoroquinolones, aminoglycosides, sulphonamides. Resistance to cephalosporins in Enterobacteriaceae is of special concern for public health, because these anti-microbial agents are critically important. The aim of this mini review was to describe the mechanisms of resistance and prevalence of ESBL-producing E. coli. It is important to investigate the spread of these bacteria among poultry, the role of farm birds as reservoir of E. coli and the risk for people.
