Taxonomic and phenotypic characterization of a novel <i>Providencia</i> species: <i>Providencia lanzhouensis</i> sp. nov.

ABSTRACT: The genus Providencia includes species of ecological and clinical significance, with several members acting as opportunistic pathogens in hospital-acquired infections, particularly urinary tract infections (UTIs). However, overlapping phenotypic traits and genetic similarities among species pose challenges for accurate identification. In this study, we isolated strain PAZ2 from a urine sample of a hospitalized patient in Lanzhou, Gansu Province, China. While initial mass spectrometry analysis identified the strain as Providencia alcalifaciens, comprehensive genomic analysis revealed distinct characteristics suggesting a novel species. Comparative genomic analyses showed average nucleotide identity (ANI) values ranging from 79.92% to 94.73% and digital DNA-DNA hybridization (d
