摘要
本文利用自行设计的半微量改良微生物学方法和紫外分光光度法对临床分离的脆弱拟杆菌进行β-内酰胺酶的定性和定量测定。结果表明106株受检菌均具有β-内酰胺酶,检出率为100%。以头孢菌素酶活性占优势,且受检菌株的耐药程度与酶的比活力之间有非常显著的正相关关系。
The beta-lactamase activity of the crude extracts from 106 strains of bacteroidesfragilis isolated from clinical specimens was detected by a modified microbiologicalmethod,and some of the crude preparations were quantitatively estimated by spec-trometric method.The results showed that 100% of the tested strains produced beta-lactamases and the beta-lectern resistance was closely correlatedto the beta-lactamasespecific activities.
