Atopobium vaginae was discovered in 1999.[3] 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.[4][5][6]
The genus may play a role in the development of Colorectal cancer. While the genus has been reported as overrepresented in feces of patients,[7] 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.[8]
Phylogeny
The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN)[1] and National Center for Biotechnology Information (NCBI).[2]
