Isolation and Drug Resistance of Salmonella Strains from Pigs in Shanghai
摘要
Abstract
In order to investigate the serotypes and drug resistance of Salmonella from pigs in Shanghai,4788 anal swabs were collected from 2015 to 2019 for bacterial isolation and identification.The susceptibility of the isolated strains to 16 common antibiotics was tested by micro-broth dilution method.A total of 106 Salmonella strains were obtained and identified with the isolation rate of 2.21%.Total 11 Salmonella serotypes were identified,of which the S.1,4,[5],12:i:-and S.typhimurium accounted for the highest proportions,55.66%and 19.81%,respectively.According to the result of resistance test,the highest resistance rates were 100%for sulfisoxazole and 77.01%foretracycline.On the contrary,these strains were susceptible to β-lactams and fluoroquinolones.In addition,10 drug resistant spectrums were identified,of which 3 or more spectrums accounted for 78.16%(68/87),and multi-drug resistances were mainly concentrated in 4-6.The results showed that the serotypes of Salmonella from pigs in Shanghai area were more complicated,mainly S.1,4,[5],12:i:-,which had serious resistance to some drugs,and multi-drug resistance requireed vigilance.Pig farms should further standardize and rationally use antibacterial drugs.关键词
