The purpose of this study was to identify the ESBL producing E. coli and the characteristics of the encoding genes. 84 rectal dog swabs from several animal clinics in Surabaya, Indonesia were taken for the study. All the 84 positive E. coli samples were conrmed by the Double Disc Synergy Test (DDST) method. Molecular identi cation of blaCTX-M and blaTEM ESBL encoding genes using mutiplex Polymerase Chain Reaction (PCR). ESBL-producing E. coli bacteria from rectal swabs were found to be 9.52% (8/84). The PCR results showed that the blaCTX-M gene consisted of 8 ESBL isolates and blaTEM gene as many as 1 ESBL isolate which have the potential as a reservoir in spreading antibiotic resistance to humans and animals

Key Words: Escherichia coli, ESBL, blaCTX-M gene, blaTEM gene, Dogs
