Strain HG370 (= ATCC 35406) is the type strain. Unlike B. gingivalis, B. endodontalis does not agglutinate sheep erythrocytes or produce phenylacetic acid. B. endodontalis resembles B. asaccharolyticus physiologically but can be distinguished by its lower deoxyribonucleic acid guanine-plus-cytosine content (50 versus 53 to 54 mol%), by its serological reactions, by its electrophoretic patterns of proteins, and possibly by its menadione requirement. %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/00207713-34-2-118
