Atopobium is a genus of Actinomycetota, in the family Coriobacteriaceae. Atopobium species are anaerobic, Gram-positive rod-shaped or elliptical bacteria found as single elements or in pairs or short chains.
Atopobium vaginae was discovered in 1999.[2] This is a facultative anaerobic bacteria, which form small colonies on blood agar at 37 °C is also positive for acid phosphatase. This species has now been reclassified into the genus Fannyhessea following phylogenetic studies.
Clinical significance
The genus Atopobium may be associated with bacterial vaginosis.[3][4][5]
The genus may play a role in the development of Colorectal cancer. While the genus has been reported as overrepresented in feces of patients,[6] A. minutum has conversely shown a mild apoptotic effect on cancer cells in vitro and has been suggested to be comparable to probiotic bacteria in regards to colorectal cancer.[7]
Phylogeny
The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN)[8] and National Center for Biotechnology Information (NCBI).[9]
