| description |
Due to the use of antibiotics for the treatment and prevention of bacterial infections in intensive poultry production, it is important to study the prevalence and resistance profile of gram-negative extended-spectrum beta-lactamase (ESBL)-producing bacteria. Among the several classes of antibiotics available, beta-lactam agents are the most widely used category in human and veterinary medicine. Thus, the objective of this work was to evaluate the resistance profile and ESBL-producing capacity of strains isolated from broiler breeders. Gram-negative bacteria were isolated in selective media from a collection of 87 cloacal swabs, and they were identified by conventional biochemical methods and MALDI-TOF mass spectrometry and studied for antibiotic resistance, including ESBL production. Of the 87 samples, 52 gram-negative bacteria were isolated. There was high bacterial resistance to the main classes of antibiotics used in poultry: cephalosporins (74.2%), quinolones (73.8%) and penicillins (73.6%). A phenotype suggestive of ESBL production was also found in 42.31% of isolates, showing resistance to the beta-lactam antibiotics tested. The results demonstrate the need for the guidance of professionals working broiler breeders to reduce the presence of drug-resistant and ESBL-producing bacteria and to prevent their spread to the environment, fertile eggs and broilers, and consequently to chicken meat and humans.
