Grimontia hollisae

Grimontia hollisae is a species of Grimontia proteobacteria (family Vibrionaceae) found naturally in marine environments. Based on phylogenetic evidence, the species was reclassified in 2003 from Vibrio hollisae.

G. hollisae is primarily associated with gastroenteritis, causing a moderate to severe diarrhea. Most recorded cases of infection occurred after the consumption of seafood, namely as oysters. Cases of bacteremia due to G. hollisae have been reported.

G. hollisae is the only pathogenic species in the Vibrionaceae family that does not grow on thiosulfate-citrate-bile salts-sucrose agar (TCBS).
