“…Five strains (2.3%) were phenotypically ESBL, whereas PCR analyses detected bla TEM , bla SHV , and bla CTX-M in 8, 3, and 7 E. coli strains, respectively. In the present study, the frequency of ESBL-producing E. coli from chicken meat was significantly higher than that reported by Çil et al [41] and Bilge et al [44]. In particular, there was a high increase in the frequency of bla TEM but no significant difference in the rate of phenotypic ESBL-producing E. coli.…”

“…ESBL-producing E. coli strains and their ESBL types have been studied in poultry production worldwide [12][13][14]40]. However, there are relatively limited data in Türkiye on ESBL-producing E. coli from chicken meat [3,4,38,41]. There is a need to understand better the epidemiology of ESBLproducing bacteria in chicken meat.…”

“…In Türkiye, 152 E. coli strains were analyzed by combining disk diffusion tests, and 28 (18.4%) strains were found to produce ESBL [41]. In another study in Türkiye, 100 chicken meat samples were collected, and 214 E. coli isolates were cultivated from 72 samples positive for E. coli [44].…”

Antimicrobial resistance is one of the major public health problems worldwide. This study aimed to detect the presence of extended-spectrum β-lactamase-(ESBL-)producing Escherichia (E.) coli in chicken meat in Istanbul, Türkiye. Raw chicken meat samples (n = 208) were collected from different sale points and analyzed for ESBL-producing E. coli. In total, 101 (48.5%) isolates were confirmed as E. coli by PCR, of which 80/101 (79.2%) demonstrated multiple antibiotic resistance. Resistance against amoxicillin-clavulanic acid was most frequent (87.1%). Eighteen isolates (17.8%) demonstrated phenotypical ESBL resistance, as assessed by the double disc synergy test (DDST). Isolates were tested for the presence of β-lactamase genes and mobilized colistin-resistant genes. The blaTEM group was most frequently detected (97.02%), followed by blaCTX m (45.5%), blaSHV (9.9%), and blaOXA-2 (0.9%). However, mcr genes and blaNDM, blaKPC, blaVIM, and blaOXA-48 genes were not found in any isolate. E. coli strains were tested for biofilm formation in six different media [Nutrient broth, LB broth, Tryptone Soya broth (TSB), TSB containing 1% sucrose, TSB containing 0.6% yeast extract, and BHI]. Biofilm formation by E. coli isolates (44/101, 43.5%) was highest in TSB with 1% sucrose. It is worth noting that all biofilm-producing isolates were found to harbor the blaTEM-1 gene, which can indicate a high level of antibiotic resistance. This is the first report about ESBL-producing E. coli in poultry meat, the exposure of consumers in Istanbul metropolitan areas, and the ability of E. coli from this region to produce biofilms.
