There are various types of vaginal infections. Therapy (antibiotic choice) depends upon the type of infection. You didn’t tell me which infective agent was isolated in the microbiological vaginal cultures. Metronidazole is efficient against certain types of infections but not against all types of vaginal infections. Vaginal infection can be also mixed so metronidazole may need to be combined with additional antibiotics. Certain types of vaginal infections (Chlamydia, Mycoplasma, Ureoplasma…) can’t be identified with standard microbiological methods (culture) so additional diagnostic procedures need to be done to completely identify all the infections.


A Pap-test is basically used to reveal precancerous (dysplasia) and cancerous lesions of the cervix. It can also reveal certain types of infections but that is not its primary purpose. A mild degree of dysplasia can be due to bacterial infection and such dysplasia usually vanishes after overcoming the infection.


You may want to consult your gynecologist about all these possibilities I mentioned.
