Barriereina

Barriereina is a genus of gram-negative bacteria belonging to the family Enterobacteriaceae. These bacteria are rod-shaped and facultative anaerobes, meaning they can survive in both the presence and absence of oxygen. Barriereina species are typically found in the gastrointestinal tracts of various animals, including mammals and reptiles.

The genus was first described in 2010 and named in honor of French microbiologist Jean-Paul Barriere. Currently, there are several recognized species within the genus Barriereina. While generally considered commensal organisms, some species have been occasionally isolated from clinical samples, though their direct role in disease is not well-established. Research into Barriereina is ongoing, with a focus on understanding their ecological niche, genetic diversity, and potential interactions with their hosts. Their identification and classification are important for accurate microbial profiling and epidemiological studies.
