First-Genome Sequence Data of an Alcaligenes nematophilus Strain EBU-23 Encoding bla Gene Implicated in Acute Childhood Gastroenteritis

Curr Microbiol. 2024 Oct 31;81(12):436. doi: 10.1007/s00284-024-03966-5.

Abstract

Although an environmental contaminant, Alcaligenes sp. are now increasingly reported in clinical infections. Here, we present a whole-genome sequence of an extended spectrum beta-lactamase (ESBL) Alcaligenes nematophilus strain EBU-23 encoding beta-lactamase, bla gene, isolated from the stool of a hospitalized infant with acute gastroenteritis in a tertiary hospital in Nigeria. Antibiotics susceptibility test revealed that the isolate was resistant to the β-lactams, cephalosporins, and penicillin, β-lactam combination, and the fluoroquinolones. Genomic analysis exposed the presence of a class A beta-lactam hydrolase gene and multiple multidrug efflux permease which may be responsible for the beta-lactamase and multidrug resistance observed with the isolate. To the best our knowledge, we describe the first whole-genome sequence of a multidrug-resistant A. nematophilus implicated in acute childhood gastroenteritis in Nigeria.
