On the basis of later research, these were placed in a new genus
Abiotrophia (Greek a, "un-," + bios, "life," + trophe, "nutrition") as A.
Brain abscesses caused by
Abiotrophia defectiva: complication of immunosuppressive therapy in a patient with connective-tissue disease.
Abiotrophia defectiva, a variant of streptococci, was first identified approximately five decades ago.

Tambien es importante nombrar algunas especies bacterianas compatibles con estados de salud como Streptococcus parasanguinis,
Abiotrophia defectiva, Gemella haemolysans, Streptococcus mitis, Streptococcus oralis, Streptococcus cristatus y Streptococcus sanguinis (6).
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).
Nutritionally variant streptococci (NVS) comprise the
Abiotrophia sp.
