【摘要】：目的通過對廣西市售速凍米面制品中檢出的86株金黃色葡萄球菌進(jìn)行腸毒素分型和耐藥性檢測,了解其產(chǎn)腸毒素特性和耐藥性。方法依據(jù)GB4789.10-2010采用ELISA方法測定金黃色葡萄球菌腸毒素SEA-SEE,利用微量肉湯法對菌株進(jìn)行藥敏試驗。結(jié)果 86株金黃色葡萄球菌中有47株腸毒素陽性,產(chǎn)腸毒素陽性率為54.65%,產(chǎn)2種以上腸毒素的有26株,在產(chǎn)毒株中占55.32%,β-內(nèi)酰胺酶陽性金黃色葡萄球菌對青霉素(95.92%)四環(huán)素(85.71%)、氯霉素(81.63%)、紅霉素(77.55%)耐藥較為嚴(yán)重,β-內(nèi)酰胺酶陽性金黃色葡萄球菌整體耐藥性顯著高于β-內(nèi)酰胺酶陰性株。結(jié)論食源性金黃色葡萄球菌產(chǎn)毒素能力較強(qiáng),對于金黃色葡萄球菌的感染治療應(yīng)根據(jù)藥敏結(jié)果選擇合理的抗生素。
[Abstract]:Objective to investigate the enterotoxin typing and drug resistance of 86 strains of Staphylococcus aureus in Guangxi sold fast frozen rice noodle products, and to understand the enterotoxin characteristics and drug resistance of Staphylococcus aureus. Methods based on GB4789.10-2010, Staphylococcus aureus enterotoxin SEA-SEE was determined by ELISA method, and the drug sensitivity test was carried out by micro broth method. Results of the 86 strains of Staphylococcus aureus, 47 enterotoxin was positive, the positive rate of enterotoxin was 54.65%, 26 strains of enterotoxin produced more than 2 species, 55.32% in the producing strains, and beta lactamase positive Staphylococcus aureus was more resistant to penicillin (95.92%) tetracycline (85.71%), chloromycin (81.63%), and erythromycin (77.55%), beta lactamase, and beta lactamase. The overall resistance of the positive Staphylococcus aureus was significantly higher than that of the beta lactamase negative strain. Conclusion the food borne Staphylococcus aureus has stronger toxin production ability. The treatment of Staphylococcus aureus infection should choose reasonable antibiotics according to the result of drug sensitivity.
