摘要
以金黄色葡萄球菌为工作菌, 用杯碟法测定氧氟沙星（OFL）在畜禽粪便中的残留。结果表明：鸡粪便中氧氟沙星的最低检测限为0.156μg/g,标准曲线的工作范围为0.156~5.00μg/g，工作曲线的日内变异系数在2.4%~3.3%、日间变异系数为3.7%~5.2%，回收率分别为79.49%~87.92%。因此,建立的方法可以满足鸡粪尿混合物中氧氟沙星的残留检测要求。
Ofloxacin residues in faeces of chicken were determined using cylinder plate method, taking Micro- coccus luteus 26003 as the test microorganism. Results showed that the detection limit of ofloxacin in faeces was 0.156 Ixg/g, and the calibration curve was linear within the range of 0.156-5.00 μg/g, variation for the microbiological method were 2.4%-3.3% in intra-assay and 3.7%-5.2% recoveries in faeces of chicken ranged from 79.49% to 87.92%.
