内蒙古地区生牛乳中金黄色葡萄球菌产肠毒素特性及对特定抗生素耐性研究

STUDIES ON INTESTINAL TOXINS ISOLATED TO SPECIFIC ANTIBIOTICS AND PATIENCE OF STAPHYLOCOCCUS AUREUS IN MILK IN INNER MONGOLIA

了解生牛乳中金黄色葡萄球菌污染状况、产肠毒素特性及耐药性,为控制生乳中金黄色葡萄球菌的污染对乳制品食用安全具有重要意义。本研究从103份样品中分离鉴定出17株金黄色葡萄球菌,检出率16.50%,10株产肠毒素阳性,阳性率58.82%,经纸片法初筛得到10株相对耐红霉素、链霉素、青霉素、氨苄西啉的菌株,并对这10株菌进行了10种抗生素的敏感性试验,青霉素、氨苄西啉的耐药率分别达41.18%、35.29%,头孢噻肟钠、链霉素的耐药性为17.65%,红霉素、氧氟沙星、头孢唑啉、阿米卡星的耐药性为11.76%,环丙沙星耐药率为5.88%,并表现出多种耐药谱。

Investigate the prevalence of enterotoxin and resistance to anti-microbial drugs of Staphylococcus aureus,which could protected health of comsumers in dairy production.The results show that： From 103 separate samples to identify 17 of Staphylococcus aureus（16.50%）, Enterotoxin production was observed in 58.82%.screening of the paper are 10 relatively resistant to erythromycin,streptomycin,penicillin,ampicillin strains,And that 10 of the 10 kinds of antibiotics to the sensitivity of tests.Drug resistan of these isolates for Penicillin、Ampicillin were 41.18%、35.29%,CefotaximeSodiium、Streptomycin were17.65%,Erythromycin、Ofloxacin 、 Cephazolin 、Amikacin were 11.76% and Ciprofloxacin was 5.88%,respectively demonstrating several different drug resistance spectra.
