33) En un estudio realizado a partir de placa dental de ninos libres de caries, los autores identificaron una sobreabundancia de Streptococcus parasanguinis, Abiotrophia defectiva, Streptococcus mitis, Streptococcus oralis y Streptococcus sanguinis.
La endocarditis con hemocuitivos negativos se presenta en 5% a 10% de los casos, esta relacionada con el comienzo de los antibioticos antes de obtener las muestras para hemocuitivos y en algunas ocasiones se explica por la presencia de germenes de dificil crecimiento (3,7); los organismos aislados en esta forma de presentacion son bacterias exigentes, como los estreptococos nutricionalmente variantes de los generos Gemelia, Abiotrophia y Granulicateila, los bacilos gramnegativos del grupo HACEK como Haemophilus parainfluenzae, H.
The Indiana patient was infected with Abiotrophia (not further speciated); Granulicatella and Abiotrophia are similar bacterial genera that are difficult to distinguish by morphologic features (10).

Classification of streptococcal species has changed over time; in the 1980s some species moved to new genera Lactococcus and Enterococcus) and more new genera were established Abiotrophia, Granulicatella, Dolosicoccus, Facklamia, Globicatella, and Ignavigranum).
elegans (originally known as Abiotrophia elegans) was first described in 1998 (1) as a catalase-negative, oxidase-negative, nonmotile, facultative anaerobic gram-positive bacterium.
The specificity of the real-time PCR assay was verified by testing genomic DNA from bacterial species that are phylogenetically close to GBS, including members of the genera Streptococcus, Lactococcus, Enterococcus, Abiotrophia, Peptostreptococcus, and Listeria.
