Pluralibacter gergoviae

Pluralibacter gergoviae is a species of Gram-negative bacteria belonging to the family Enterobacteriaceae. It was previously classified under the genus Enterobacter but was reclassified based on genetic and phenotypic analyses.

Characteristics

Pluralibacter gergoviae is a rod-shaped, non-spore-forming bacterium. It is facultatively anaerobic, meaning it can grow in both the presence and absence of oxygen. The bacterium is motile due to the presence of peritrichous flagella. It is oxidase-negative and catalase-positive, which are important biochemical characteristics used for its identification.

Habitat

Pluralibacter gergoviae is commonly found in various environments, including soil, water, and plants. It has also been isolated from clinical specimens, indicating its potential as an opportunistic pathogen.

Pathogenicity

While Pluralibacter gergoviae is not typically associated with severe infections, it can act as an opportunistic pathogen, particularly in immunocompromised individuals. It has been isolated from cases of urinary tract infections, respiratory infections, and wound infections. The bacterium's ability to form biofilms on medical devices can contribute to its pathogenicity.

Antibiotic Resistance

Pluralibacter gergoviae has shown resistance to multiple antibiotics, which poses a challenge in clinical settings. The mechanisms of resistance include the production of beta-lactamases and efflux pumps. Monitoring and controlling the spread of antibiotic-resistant strains is crucial for public health.

Taxonomy

The reclassification of this bacterium from the genus Enterobacter to Pluralibacter was based on comprehensive genetic studies, including 16S rRNA gene sequencing. The genus name "Pluralibacter" reflects its diverse habitats and ecological niches.

Related Species

Pluralibacter gergoviae is closely related to other species within the Enterobacteriaceae family, such as Enterobacter cloacae and Klebsiella pneumoniae. These species share similar habitats and can also act as opportunistic pathogens.
