Detection of a new bla_OXA-51-Like variant (bla_OXA-1328) and a novel sequence type (ST3457/2790) in Acinetobacter baumannii isolated from community sewage and an incinerator surface in Nigeria.

ABSTRACT:

Objectives

Acinetobacter baumannii is an opportunistic pathogen with a high capacity to acquire antimicrobial resistance determinants, including OXA-type β-lactamases, which confer resistance to carbapenems. Environmental reservoirs play a crucial role in the persistence and spread of the bacteria; yet, limited data exist on variants of A. baumannii from non-hospital environments; an area critical to epidemiological studies in Nigeria. This study aimed to investigate the genetic diversity of A. baumannii strains from different non-hospital environments in Nigeria, determine their sequence types, and characterize their resistance genes.

Results

In the course of investigating the prevalence of A. baumannii in 440 environmental samples of soil, sewage, water, and air, collected
