The aim of the study was to assess the drug resistance profile of E. coli bacteria isolated from municipal waste. It was visible whether among the collected isolates there are strains resistant to ESBL mechanisms (extended spectrum β-lactamase) and whether they are resistant to β-lactam antibiotics. Analysis of the use of disk diffusion methods, using 7 final results for β-lactams (including 2 penicillins, 5 cephalosporins). The obtained comparative results with the KORLD (National Reference Center for Antimicrobial Susceptibility) and EUCAST (European Committee for Antimicrobial Susceptibility Testing) standards. The analysis distinguished that among 70% of isolates there is no resistance marking to unconfirmed from the tested antibiotics. On the contrary, 30% of strains were resistant to more than 1 antibiotic. Intermediate susceptibility to cefazolin is characteristic of 80% of E. coli strains. The largest number, as many as 20% of strains, were resistant to this antibiotic. In contrast to 100% susceptibility compared to amoxicillin with clavulanic acid, which should be used for penicillin. The ESBL mechanism is not a habitat. It has been found that municipal waste is a place of residence of E. coli bacteria resistant to antibiotics. It is very important to continue research on this source of drug ...
