Isolation was performed on Hektoen agar and bacterial identification was carried out by API20E system and Maldi-TOF-MS (matrix-assisted laser desorption\/ionization time-of-flight mass spectrometry). Antimicrobial susceptibility was tested by the disk diffusion and agar dilution methods. Detection of ESBLs and other resistance and integron genes, phylogenetic grouping, and molecular typing was performed by PCR and sequencing. Seventy-eight isolates (one per positive sample) were recovered: 73\n E. coli<\/jats:italic>\n and 5\n K. pneumoniae<\/jats:italic>\n . Among\n E. coli<\/jats:italic>\n , 86.3% of isolates were MDR. ESBL activity was revealed in eight\n E. coli<\/jats:italic>\n and five\n K. pneumonia<\/jats:italic>\n e isolates (rates of 5.9% and 3.7% in analyzed samples, respectively). ESBL genes detected among\n E. coli<\/jats:italic>\n were as follows (number of isolates):\n bla<\/jats:italic>\n CTX-M-15<\/jats:sub>\n (3),\n bla<\/jats:italic>\n CTX-M-1<\/jats:sub>\n (3),\n bla<\/jats:italic>\n CTX-M-55<\/jats:sub>\n (1), and\n bla<\/jats:italic>\n SHV-12<\/jats:sub>\n (1); all ESBL-producing\n K. pneumoniae<\/jats:italic>\n isolates carried the\n bla<\/jats:italic>\n CTX-M-15<\/jats:sub>\n gene. ESBL-producing\n E. coli<\/jats:italic>\n isolates were assigned to lineages (phylogroup\/sequence type and number of isolates in parenthesis): A\/ST48 (1), B1\/ST6448 (1), B1\/ST5087 (3), B1\/ST23 (1), and B2\/ST131 (two\n bla<\/jats:italic>\n CTX-M-15<\/jats:sub>\n E. coli<\/jats:italic>\n isolates).\n K. pneumoniae<\/jats:italic>\n isolates were ascribed to sequence types ST2010 and ST3483. Regarding the 65 non-ESBL\n E. coli<\/jats:italic>\n isolates, the most observed resistance genes were as follows:\n tet<\/jats:italic>\n (A) (75%),\n bla<\/jats:italic>\n TEM<\/jats:sub>\n (57.1%), and\n sul2<\/jats:italic>\n (43.5%). Class1 integrons were revealed in seven non-ESBL\n E. coli<\/jats:italic>\n isolates (10.7%) and two gene-cassette arrays were identified:\n dfrA<\/jats:italic>\n 1 and\n aadA<\/jats:italic>\n 1\n +dfrA<\/jats:italic>\n 1.
