The genus Abiotrophia (Kawamura et al.) is not monophyletic: proposal of Granulicatella gen. nov., Granulicatella adiacens comb. nov., Granulicatella elegans comb. nov. and Granulicatella balaenopterae comb. nov.
The genus Abiotrophia currently includes four species, Abiotrophia defectiva, Abiotrophia adiacens, Abiotrophia balaenopterae and Abiotrophia elegans. Recent 16S rRNA gene sequencing studies have demonstrated that the genus is not monophyletic and is in need of taxonomic revision. Phylogenetically, the genus Abiotrophia consists of two distinct lines, A. defectiva, the type species of the genus...
متن کاملAntimicrobial Susceptibilities of Abiotrophia defectiva, Granulicatella adiacens, and Granulicatella elegans.
Nutritionally variant streptococci (NVS) are fastidious Gram-positive cocci comprised of the species Abiotrophia defectiva, Granulicatella adiacens, and Granulicatella elegans. NVS are an important cause of bacteremia and infective endocarditis (IE) associated with significant morbidity and mortality. Antimicrobial susceptibility testing (AST) was performed for 14 antimicrobials using the broth...
متن کاملEndocarditis caused by Abiotrophia defectiva
A 35-year-old man with pre-existing rheumatic heart disease and aortic regurgitation (AR) presented with intermittent fever, ankle swelling and clinical evidence of endocarditis. Transoesophageal echocardiogram (TEE) revealed vegetations and destruction of the aortic valve (AV). Blood cultures grew a gram positive coccobacillus which was phenotypically identified as Abiotrophia defectvia (A.def...
متن کاملAbiotrophia elegans strains comprise 8% of the nutritionally variant streptococci isolated from the human mouth.
Ninety-one isolates of nutritionally variant streptococci (NVS) that were previously isolated from the human mouth were regarded as consisting of 7 Streptococcus defectivus isolates, 78 Streptococcus adjacens isolates, and 6 Gemella morbillorum isolates. However, recent references to the taxonomic reclassification of NVS, from S. defectivus to Abiotrophia defectiva and from S. adjacens to Abiot...
متن کاملReclassification of the polyphyletic genus Prosthecomicrobium to form two novel genera, Vasilyevaea gen. nov. and Bauldia gen. nov. with four new combinations: Vasilyevaea enhydra comb. nov., Vasilyevaea mishustinii comb. nov., Bauldia consociata comb. nov. and Bauldia litoralis comb. nov.
Species of the genus Prosthecomicrobium are noted for their numerous cellular appendages or prosthecae that extend from the cells. This investigation confirms that the genus is polyphyletic based on an extensive analysis of the 16S rRNA gene sequences of several named species of the genus. The analyses indicate that some Prosthecomicrobium species are more closely related to non-prosthecate gen...
