Oral and faecalsamples were collected from thirty four dogs with periodontal disease in Chiang Mai, Thailand to investigate the prevalence of Extended Spectrum Beta Lactamase -producing E. coli(ESBL-EC) and to determine the antimicrobial resistance patterns of isolatesagainst 12 antimicrobial agents. Ten of thirty-four dogs (29.41%) were positive for ESBL-EC, one dog (2.94%) was positive from an oral sample and nine dogs (26.47%) were positive from faecal samples. All ESBL-EC isolates were multi-drug resistant (i.e. against ≥ 3 antimicrobial classes). All isolates were 100% resistant to Ampicillin, Cefazolin, Cephalexin, Ciprofloxacin and Clindamycin, and 100% susceptible to Imipenem. AMP-AMC-KZ-CL-ATM-DO-CIP-SXT-DA was the most common resistance pattern identified.
