Gemella

Gemella
A genus of motile, aerobic, facultatively anaerobic, coccoid bacteria (family Streptococcaceae) that occur singly or in pairs, with flattened adjacent sides. They are Gram-indeterminate but have a cell wall like that of Gram-positive bacteria, and are parasitic on mammals. The type species is G. haemolysans, which is found in bronchial secretions and in mucus from the respiratory tract. [L. dim. of geminus, twin]
- G. morbillorum a microaerophilic bacterium, formerly called Streptococcus morbillorum, that fails to produce β-hemolysis of blood agar and lacks distinguishing serogroup antigens; causes serious infections in some patients similar to those seen with viridans streptococci.
