Identification of TEM-135 β-lactamase in Neisseria gonorrhoeae strains carrying African and Toronto plasmids in Argentina.

ABSTRACT: 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.
