Resistance of Salmonella Isolates from Swine Fecal in a Pig Farm to Antibiotics

Abstract

Abstract: In order to investigate the resistance of Salmonella isolated from a pig farm and guide reasonable use of clinical antimicrobial drugs in Urumqi, Xinjiang, minimum inhibitory concentrations of 58 strains of Salmonella isolated from 550 fecal samples were determined by agar dilution method. The results showed that the resistance rate of Salmonella presented a high level to tetracycline (100.0% ), ciprofloxacin (96.6% ), enrofloxacin (94.8%), amoxicillin/clavulanate (91.4%), kanamycin (89.6%), florfenicol (84.5%) and ampicillin (75.9%); and presented a moderate level to amikacin (58.6%), apramycin (55.2%), norfloxacin (51.7%) and gentamicin (50.0%); and was sensitive to ceftiofur (8.6%). The resistance rate of Salmonella from pig fecal in this farm to commonly used antibiotics was serious, indicating that alternative and combined use of antibiotics should be adopted in the clinic.
