Thirty-six percent of the isolates (n\u2009=\u200945) were resistant to 3GCs. Of these isolates, 34 were tested by PCR and nucleotide sequencing and 23 were confirmed as encoding \u03b2-lactamase genes. Fourteen 3GC-resistant isolates harboured extended-spectrum \u03b2-lactamases (ESBLs) belonging to groups CTX-M-1 (n\u2009=\u200912, two of which were CTX-M-79), CTX-M-2 (n\u2009=\u20091) and CTX-M-9 (n\u2009=\u20091), as well as SHV-12 (n\u2009=\u20091) and TEM-92 (n\u2009=\u20091). Nine isolates had CMY-2 plasmid-mediated AmpC \u03b2-lactamases (pAmpC). Thirty-one percent (n\u2009=\u200939) of the isolates were multidrug resistant (MDR) and were isolated from 34% (n\u2009=\u200931\/90) of the cats.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions and relevance<\/jats:title>\n                    <jats:p>A high frequency of MDR and ESBL\/pAmpC \u03b2-lactamase-producing Enterobacteriaceae were detected among bacteria isolated from a feline population in southern Italy with a variety of common clinical conditions, which poses limitations on therapeutic options for companion animals.
