<prompt> All are true about Doderleins bacillus, EXCEPT?Gram positive bacteriaGrows in acidic mediaConves glycogen into lactic acidEstrogen suppresses growth of this bacillus  <response>: Doderleins bacillus: Rod-shaped gram-positive bacillus which grows anaerobically on acid media, Appears in the vagina 3-4 days after bih and disappears after 10-14 days, Its presence is dependent on estrogen, Function is to conve the glycogen present in the vaginal mucosa into lactic acid so that the vaginal pH is maintained towards acidic side.
