This study is to survey the prevalence and antibiotic resistance pattern of Salmonella spp. isolated from the farms at Dak Lak province, Viet Nam. 139 farms including 5 civet farms, 14 pig farms and 120 duck farms were sampled and analyzed. The results showed that many samples collected from 120 duck farms,14 pig farms and 5 civet farms were positive positive for Salmonella spp. Four serogroups of Salmonella species were demonstrated, Salmonella group B (25 strains), Salmonella group non-typable (13 strains), Salmonella group D (8 strains) and Salmonella group C (2 strains). There were 50 % of Salmonella strains resisting to at least one antibiotic, 75 % of the strains expressing multiple antibiotic resistance. In particular, 3 strains Salmonella secreted to ESBL (Extented-spectrum- beta lactamse).
