Abiotrophia is a genus of lactic acid bacteria, a family in the phylum Bacillota (Bacteria).
The genus contains 4 species of coccus shaped species, [2] 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 . [7]
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. [2]
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% [8]
Formerly classified as nutritionally variant streptococci, A. elegans had been identified as a cause of 1 to 2% of blood culture negative bacterial endocarditis. [9]
Acetomicrobium is a genus in the phylum Synergistota (Bacteria). In 2016, the former genus Anaerobaculum was folded into Acetomicrobium.
Thermoanaerobacter is a genus in the phylum Bacillota (Bacteria). Members of this genus are thermophilic and anaerobic, several of them were previously described as Clostridium species and members of the now obsolete genera Acetogenium and Thermobacteroides
Acidiphilium is a genus in the phylum Pseudomonadota (Bacteria). As the name suggests, this comprises a nutritionally diverse genus of bacteria adapted to life in extremely acidic conditions, and often exhibiting FeIII reduction.
Acidiplasma is a genus in the phylum Euryarchaeota (Archaea).
Acrocarpospora is a genus in the phylum Actinomycetota (Bacteria). The major respiratory quinone is menaquinone MK-9(H ) and use madurose, an actinomycete whole-cell sugar.
Actinocatenispora is a genus in the phylum Actinomycetota (Bacteria).
Actinocorallia is a genus in the phylum Actinomycetota (Bacteria).
Actinokineospora is a genus in the phylum Actinomycetota (Bacteria).
Actinopolymorpha is a genus in the phylum Actinomycetota (Bacteria).
Actinospica is a genus in the phylum Actinomycetota (Bacteria).
Actinotalea is a genus in the phylum Actinomycetota (bacteria).
Aeriscardovia aeriphila is a species of bacteria in the phylum Actinomycetota.
Dechloromonas is a genus in the phylum Pseudomonadota (Bacteria).
Agromyces is a genus in the phylum Actinomycetota (Bacteria).
Algoriphagus is a genus in the phylum Bacteroidota (Bacteria).
Alishewanella is a genus in the phylum Pseudomonadota (bacteria).
Alkalimonas is a genus in the phylum Pseudomonadota (Bacteria).
Croceitalea is a genus in the phylum Bacteroidota (Bacteria).
Desulfobacula is a bacterial genus in the family Desulfobacteraceae.
Granulicatella adiacens is a fastidious Gram-positive cocci and is part of the nutritionally variant streptococci (NVS). Like other constituents of the NVS, it can cause bacteremia and infective endocarditis (IE), with significant morbidity and mortality. NVS has less often been implicated in a variety of other infections, including those of the orbit, nasolacrimal duct and breast implants. It is a commensal of the human mouth, genital, and intestinal tracts, although it is rarely implicated in infections, in part due to it being a fastidious organism and rarely being identified in the laboratory environment. However, its identification has become more frequent with use of commercial mediums and automated identification systems. Because it has been difficult to identify, it has been considered one of the causes of culture negative IE. Identifying G. adiacens can allow more appropriate selection of antibiotics, especially when susceptibility testing is not available.
