Abiotrophia Explained

Abiotrophia is a genus of lactic acid bacteria, a family in the phylum Bacillota (Bacteria).

Species

The genus contains 4 species of coccus shaped species, 2 are former members of the genus Streptococcus, which were transferred in 1995 to the newly coined genus Abiotrophia:[1]

Other 2 are latter additions:

In 2000, Collins and Lawsons further differentiated A. adiacens, A. balaenopterae and A. elegans from A. defectiva by placing them into the new genus Granulicatella.[6]

Etymology

See also: Bacterial taxonomy. The name Abiotrophia derives from:Greek prefix ἄ (a)-, negative (un-); Greek noun βιος (bios), life; Greek noun τροφιά (trophia), nutrition; Neo-Latin feminine gender noun Abiotrophia, life-nutrition-deficiency.

Genome Sequence

For the Human Microbiome Project (HMP), the genome of Abiotrophia defectiva ATCC 49176 has been sequenced (assembly) as it is a resident of human oral cavity and urogenital and intestinal tracts and is a cause of infective endocarditis,showing it to have 3291 protein encoded in a 3.4774 Mbp genome with a GC content of 37.0%[7]

Disease

Formerly classified as nutritionally variant streptococci, A. elegans had been identified as a cause of 1 to 2% of blood culture negative bacterial infective endocarditis.[8]
