Culture and sensitivity testing are usually done from cervical swab specimens collected from women who are having abnormal vaginal discharges and possible genitourinary tract infections. Such conditions are usually caused by aerobic bacterial organisms. Culturing bacteria helps in creating bacterial colonies in a petri dish and then different antibiotics are added to the dish and the most effective antibiotic that can eliminate maximum number of bacteria is identified. This helps in more accurate treatment of the particular infection. Local gonococcal infections in women primarily affect the cervix and are often does not to show any particular symptoms, but can cause an increased vaginal discharge, genital itching or dysuria.
