: an Emerging Pathogen in Humans
Overview
Affiliations
The complex comprises seven related species, including . is a versatile bacterium capable of colonizing different hosts such as plants, humans, insects and animals. Currently, is gaining recognition as a cause of several human infections; nevertheless, its virulence profile is not fully characterized. The clinical significance of infection is hidden by imprecise detection methods that underestimate its real prevalence; however, several methods have been developed to correctly identify this species. Recent studies of carbapenemase-producing and colistin-resistant strains demonstrate a potential reservoir of multidrug-resistant genes. This finding presents an imminent scenario for spreading antimicrobial resistant genes among close relatives and, more concerningly, in clinical and environmental settings. Since was identified as a novel bacterial species, different research groups have contributed findings elucidating this pathogen; however, important details about its epidemiology, pathogenesis and ecology are still missing. This review highlights the most significant aspects of , discussing its different phenotypes, mechanisms of resistance, and virulence traits, as well as the types of infections associated with this pathogen.
