One hundred forty-three penicillinase-producing Neisseria gonorrhoeae (PPNG) isolates obtained in Argentina from 2008 and 2012 were examined to detect blaTEM-135 genes and to investigate plasmid profiles and multiantigen sequence types. Forty-two PPNG isolates were found to carry TEM-135, and two contained a new TEM derivative characterized as TEM-220. The blaTEM-135 allele was carried by the Toronto/Rio and African plasmids. Molecular epidemiology revealed that two blaTEM-135 isolates were related to previously described isolates from Thailand and China, indicating a common evolutionary origin.
对2008年至2012年在阿根廷获得的143株产青霉素酶淋病奈瑟菌(PPNG)分离株进行检测,以检测blaTEM-135基因,并研究质粒图谱和多抗原序列类型。发现42株PPNG分离株携带TEM-135,其中两株含有一种新的TEM衍生物,被鉴定为TEM-220。blaTEM-135等位基因由多伦多/里约热内卢质粒和非洲质粒携带。分子流行病学研究表明,两株携带blaTEM-135的分离株与先前描述的来自泰国和中国的分离株有关,表明它们有共同的进化起源。
