The nucleotide sequences of 59 bla(TEM) genes encoding inhibitor-resistant TEM enzymes showed great genetic variability and were associated with different types of promoters. These findings led us to suggest an updated bla(TEM) gene nomenclature based on the origin of the bla(TEM) gene (bla(TEM-1A), bla(TEM-1B), bla(TEM-1C), bla(TEM-1D), bla(TEM-1E), and bla(TEM-1F)) and the promoter type.

To determine the prevalence and genotypes of extended-spectrum beta-lactamases (ESBLs) among clinical isolates of Klebsiella pneumoniae and Escherichia coli, we performed antibiotic susceptibility testing, pI determination, induction testing, transconjugation, and DNA sequencing analysis. Among the 509 isolates collected from 13 university hospitals in Korea, 39.2% produced ESBLs. ESBL-producin...

Cephalosporin resistance, particularly due to bla(TEM) encoded β-lactamases, among Enterobacteriaceae is, though, an increasing public health problem in India; their circulating genetic variants remain unknown. The present study deals with determination of bla(TEM) variants among 134 pathogenic Enterobacteriaceae of Indian origin. Their resistance profile against 3rd generation cephalosporins w...

BACKGROUND Penicillinase-producing Neisseria gonorroheae (PPNG) was first isolated in 1976. PPNG strains carrying bla TEM-1 and bla TEM-135 gene have been described in different countries. Recently, a novel bla TEM-220 allele was detected in PPNG isolates carrying Toronto/Rio plasmid. The prevalence and characteristics of TEM-220 strains worldwide are unknown, and therefore, it needs to be stud...

BACKGROUND Prognostic models for natural conception help to identify subfertile couples with high chances of natural conception, who do not need fertility treatment yet. The use of such models and subsequent tailored expectant management (TEM) is not always practiced. Previous qualitative research has identified barriers and facilitators of TEM among patients and professionals. The aim of this ...
