[Occurrence of beta-lactamase types ESBL and AmpC among gram-negative rods isolated from food].
The aim of the study was to isolate extended spectrum beta-laktamases (ESBL) and chromosomal beta-laktamases AmpC producing strains from food products. A total of 739 Gram-negative bacteria were tested with double disc diffusion method using cefotaxim, ceftasidim and amoxycillin with clavulanic acid. One strain producing ESBL and belonging to Stenotrophomonas maltophilia was detected from the ice cream (0.14% of all strains). From different food products a total of 14 microorganisms (1.9%) having AmpC enzymes have been isolated. They belonged to Enterobacter spp, Hafnia spp, Morganella spp, Citrobacter, Acinetobacter, and Cedecea. Appearance of strains producing beta-laktamases ESBL and AmpC among microorganism isolated from food make it necessary to monitor enzymes activity during routine microbiological control of foods.
