Abstract

From genomic DNA of Ralstonia pickettii isolate PIC-1, a beta-lactamase gene was cloned that encodes the oxacillinase OXA-22. It differs from known oxacillinases, being most closely related to OXA-9 (38% amino acid identity). The hydrolytic spectrum of OXA-22 is limited mostly to benzylpenicillin, cloxacillin, and restricted-spectrum cephalosporins. OXA-22-like genes were identified as single chromosomal copies in five other R. pickettii clinical isolates. The expression of OXA-22-like beta-lactamases was inducible in R. pickettii.

摘要

从皮氏罗尔斯通氏菌分离株PIC-1的基因组DNA中克隆到一个编码奥沙西林酶OXA-22的β-内酰胺酶基因。它与已知的奥沙西林酶不同,与OXA-9的关系最为密切(氨基酸同一性为38%)。OXA-22的水解谱主要限于苄青霉素、氯唑西林和窄谱头孢菌素。在其他5株皮氏罗尔斯通氏菌临床分离株中,OXA-22样基因被鉴定为单染色体拷贝。OXA-22样β-内酰胺酶在皮氏罗尔斯通氏菌中可诱导表达。
