Vaginal Haemophilus vaginitis is caused by Haemophilus vaginalis. Studies have found that when secretion examination does not find specific pathogens such as Trichomonas or fungi, it is often diagnosed as nonspecific vaginitis. 90% of nonspecific vaginitis are found to contain Haemophilus vaginalis through secretion smear microscopy or bacterial culture. Since about 40% of normal healthy women have Haemophilus vaginalis in their vagina, clinical symptoms may appear when the bacteria reach a certain number or the vaginal immune mechanism is damaged. Other common vaginitis include: nonspecific vaginitis, bacterial vaginitis, candidal vaginitis, trichomonas vaginitis, fungal vaginitis, pinworm vaginitis, allergic vaginitis, tuberculous vaginitis, amebic vaginitis, senile vaginitis, and infantile vaginitis.
