摘　　要：本研究旨在比较夏、冬两季某规模化养猪场猪源葡萄球菌的耐药情况。分别在夏、冬两季对猪场同一猪采集其直肠肛拭子样和鼻腔鼻拭子样,采用微量肉汤稀释法对分离出的葡萄球菌进行临床9种常用抗菌药物的药敏试验。结果显示,夏季鼻腔分离的葡萄球菌对阿米卡星、氟苯尼考、氧氟沙星、苯唑西林和克林霉素5种抗菌药物的耐药率均高于冬季分离的鼻腔菌。夏季直肠分离的葡萄球菌对阿莫西林/克拉维酸、苯唑西林、庆大霉素、氧氟沙星、四环素、克林霉素和利福平7种抗菌药物的耐药率低于冬季分离的直肠菌。且夏、冬两季鼻腔分离的葡萄球菌多药耐药种数在0~9耐均有分布,夏、冬两季直肠分离的葡萄球菌多药耐药种数在1~9均耐有分布。冬季鼻腔分离的葡萄球菌6耐的多药百分率显著高于夏季分离菌的多药百分率(P<0.05),冬季直肠分离的葡萄球菌8耐的多药百分率显著高于夏季分离菌的多药百分率(P<0.05)。结果表明,夏、冬两季猪不同部位分离的葡萄球菌对大多数被检抗菌药物的耐药率情况不同,其耐药率与养殖场季节性用药呈现相关性。In this study,the resistance of swine Staphylococcusisolated in summer and winter was compared.The rectal anal swab samples and nasal swab samples were collected from the same pig in summer and winter.The susceptibility test of 9kinds of antimicrobial drugs was carried out by using the broth dilution method.The results revealed that the resistance rates of Staphylococcus isolated from the rectum in summer were higher than that of Staphylococcus isolated from the rectum in winter to amikacin,florfenicol,levofloxacin,benzene and clindamycin.Resistance rates of Staphylococcus isolates from nasal cavity in summer were lower than that of Staphylo coccusisolates from nasal cavity in winter to amikacin,benzene,gentamicin,levofloxacin,tetracycline,clindamycin and rifampicin.And Staphylococcus in two seasons in 0to 9resistant rectal separation resistance were distributed.Multi drug resistant Staphylococcusin two seasons in 1to9 resistant rectal separation resistance were distributed.And in the 6resistance,the resistance rate of Staphylococcusisolated from the nasal in summer was significantly higher than that of the isolated from anal in winter（P0.05）.And in 8resistance,the resistance rate of Staphylococcus isolated from the rectum cavity in summer was significantly higher than that of Staphylococcus isolated from the rectum cavity in winter（P0.05）.Results showed that the resistance rates of Staphylococcus isolated from different sites of the pigs to the tested antimicrobial drugs were different.The drug resistance rate was correlated with seasonal use of the farm.
