A comparison between STD clinic attendees with Chlamydia trachomatis or Mycoplasma genitalium infection and a screening group of women, without these infections.
Patients with dual C trachomatis and M genitalium infection (n = 4) were excluded in comparisons as well as five patients with C trachomatis infection, where smears were not sampled.
*PMNL per HPF.
†Microscopic cervicitis was defined as more PMNL than vaginal epithelial cells (EP) in wet smear.
‡Urethritis defined as >4 PMNL/HPF.
§Urethral smear was not sampled from one patient, who had a microscopically verified cervicitis.
