Pluralibacter gergoviae

Pluralibacter gergoviae (formerly Enterobacter gergoviae) is a Gram-negative, motile, facultatively-anaerobic, rod-shaped bacterium.[1] P. gergoviae is of special interest to the cosmetics industry, as it displays resistance to parabens, a common antimicrobial agent added to cosmetic products.[3]

Background

Enterobacter gergoviae was first proposed as a novel species in 1980. The species name is derived from the Gergovie plateau, which is located near Clermont-Ferrand University Hospital; the type strain was isolated at this hospital during a nosocomial outbreak of P. gergoviae.[1] In 2013, the species was reclassified into the novel genus, Pluralibacter, and is the type species for the genus.[2]

Pluralibacter gergoviae has been isolated from maize, grapes, coffee beans, spring water, fruit flies, and pink bollworms.[4] It is an uncommon human pathogen, most commonly as an opportunistic nosocomial infection. One hospital in Spain reported the organism to represent 0.4% of clinical Enterobacter isolates. Risk factors include prolonged hospital stays, "immunosuppression, the presence of a foreign device, prior use of anti-microbial agents in the patient involved, and extremes of age."[5] In the cosmetic industry, P. gergoviae has been implicated in recalls of eye cream, children's shampoo, skin cream, hand cleaning paste,[6] and cleansing wipes.[7]

Pluralibacter gergoviae is resistant to penicillins (specifically benzylpenicillin, oxacillin), macrolides (with the exception of azithromycin), lincosamides (specifically lincomycin and clindamycin), streptogramins, rifampicin, fusidic acid, and fosfomycin.[8] P. gergoviae is also resistant to cefoxitin, likely due to β-lactamase production.[8]
