It is a facultative anaerobic[1] Gram positive coccus usually preferring capnophilic or microaerophilic environments.[2] From its discovery in 1917 (by R. Tunnicliff) until 1988, it was known as Streptococcus morbillorum (and briefly as Peptostreptococcus morbillorum [3]). The name change followed closer examination with DNA filter hybridization (by Kilpper-Balz and Schleifer) which found it was very close to the species Gemella haemolysans.[4] PathogenicityG. morbillorum is rarely a cause of disease in humans, though it may be found benignly in the oropharyngeal area. Infections, when found, are similar to viridans Streptococci in range. Cases have been reported of endovascular infections (predominantly endocarditis[5][6]) and also acute invasive infections. It has also been reported as among the most common bacteria present in teeth with cysts that do not resolve after repeated root canal treatments.[7]A report of a human infection involving G. morbillorum in an Indian child was reported in 1999.[8] Strains of this species are commonly resistant to penicillin.[9] Bacteremia with G. morbillorum, among other bacteria, has been associated with colorectal cancer.[10] References1. ^Journal of Medical Microbiology (2009), 58, 1652–1656 2. ^{{cite book|last1=Ruoff|first1=Katheryn L.|title=Aerococcus, Abiotrophia, and other Aerobic Catalase-Negative, Gram Positive Cocci in Manual of Clinical Microbiology 10th Ed.|date=2011|publisher=ASM Press|location=Washington DC|pages=365–376}} 3. ^{{cite journal|last=Romond|first=Ch.|title=The taxonomy of the peptococcaceae|journal=Infection|date=March 1980|volume=8|issue=S2|pages=S153–S154|doi=10.1007/BF01639880}} 4. ^{{cite journal|last=KILPPER-BaLZ|first=R.|author2=SCHLEIFER, K.
