The purpose of this study was to detect the incidence of multi-drug resistant (MDR) and the spread of genes that encode tetracycline (TE) resistance in in pig farms in the city of Kupang, Indonesia.Samples of pig feces have been obtained from 96 pig farms in Kupang city, Indonesia. bacteria were isolated and identified morphologically and biochemically, and finally confirmed by the API test. The disk diffusion method has been used to observe the antibiotic sensitivity effects and has been followed by observing resistant genes encoding TE resistance using the multiplex polymerase chain reaction (m-PCR) method to detect the presence of genes such as (A), (B), (C), (D), and (E), respectively.A total of 82 (85.4%) of isolates have been found in all pig feces samples obtained from 96 pig farms in Kupang city. This study has shown a high level of antibiotic resistance dominated by erythromycin (85.4%) and cephalothin (58.5%) and followed by several other antibiotics with a percentage below 34.1%. The prevalence of MDR was 57.3% by showing 39 different patterns. The most common pattern was showed by the Cephalothin-Colistin-Erythromycin pattern. The resistance of to TE appears to be related to the presence of (A) and (E) genes.This study has encouraged the need for public awareness (farmers) of the wise use of antibiotics in preventing the spread of resistant bacteria that can cause health problems in animals and humans.
