Isolation, Identification and Drug Resistance Analysis of Streptococcus suis in Henan Province
摘要
Abstract
In order to investigate the serotype distribution and drug resistance of Streptococcus suis in Henan province.Isolation and culture,biochemical and PCR identification of suspected Streptococcus suis were performed on disease materials collected from pig farms in Henan province from May 2016 to May 2017.Identification of serum groups and serotype and the susceptibility test of Streptococcus suis serotype 2 was carried out.The results showed that 189 strains Streptococcus suis were identified,the epidemic group of Streptococcus suis in Henan province was mainly D group,followed by G and C groups;The predominant serotypes were type 2,type 7,type 9 and type 1.Among them,87 strains were Streptococcussuis type 2.More than 90％ of the isolates were susceptible to beta lactams (penicillin G,amoxicillin and cephalosporins),chloramphenicol,vancomycin and ciprofloxacin,and more than 40％ strains were resistant to doxycycline,tetracycline,erythromycin,sulfamethoxazole,amikacin,clindamycin,streptomycin,minocycline resistance.These results had practical significance for guiding the use of sensitive drugs in the pig farm,controlling the epidemic situation,reducing the loss,and guiding to choose the vaccine with the same serotype.关键词
