STRUCTURE AND PHYSIOLOGY
P. gergoviaeis a gram-negative, rod-shaped, facultative anaerobe that can be found in some plants, insects, and spring water.
TRANSMISSION AND DISEASE
It is considered an uncommon human pathogen associated with nosocomial infections in immunocompromised individuals. Risk factors include long hospital stays, use of steroids or antimicrobial agents, foreign devices, or age.
More recently, P. gergoviae has been implicated in several recalls involving cosmetic products such as eye and skin creams as well as baby shampoo. This bacterium is resistant to parabens, a common antimicrobial agent in cosmetics, as well as several antibiotics.
P. gergoviae was originally classified under the Genus “Enterobacter” before being reclassified as the novel Genus “Pluralibacter”. It is now the type species for Pluralibacter.
