Information is presented on the plasmid-determined beta-lactamases identified in 204 strains of ampicillin-resistant Enterobacteriaceae. The type most frequently identified was TEM-1 (in 85.3% of the strains), followed by SHV-1 (14.70%). Two types of plasmid-determined beta-lactamase were identified in 20 strains; in 18 of them one of the two was TEM-1 and in 13, SHV-1 (the TEM-1 + SHV-1 combination was observed in 12 strains). In the 41 Klebsiella strains the most frequently identified enzyme was SHV-1 (in 28 of the strains) and the proportion of strains with two plasmid-determined beta-lactamases was higher than in the other species studied.
本文介绍了在204株耐氨苄西林肠杆菌科细菌中鉴定出的由质粒介导的β-内酰胺酶。最常见的类型是TEM-1（占菌株的85.3%），其次是SHV-1（14.70%）。在20株细菌中鉴定出两种由质粒介导的β-内酰胺酶；其中18株中两种酶之一是TEM-1，13株中是SHV-1（12株中观察到TEM-1 + SHV-1组合）。在41株克雷伯菌中，最常鉴定出的酶是SHV-1（28株），并且具有两种由质粒介导的β-内酰胺酶的菌株比例高于其他研究的菌种。
