Phylogenetic relationship of Gemella morbillorum to Gemella haemolysans

Int J Syst Bacteriol. 1993 Oct;43(4):832-8. doi: 10.1099/00207713-43-4-832.


Partial 16S rRNA gene sequences (16S rDNA) of Gemella morbillorum and Gemella haemolysans were determined by sequencing polymerase chain reaction-amplified DNA. A phylogenetic analysis of 53 eubacterial 16S rRNA sequences grouped the gemellae on a distinct branch separate from the 18 members of the genus Streptococcus. DNA-DNA hybridization results indicate that the two gemellae are related at the genus level but are not a single species.
