[Epidemiologic observations on Chlamydia trachomatis infections]

A group of 82 patients (77 with urethritis) was studied for the presence of Chlamydia trachomatis infection. The agent was isolated by inoculation on McCoy cell cultures, followed by Giemsa and/or Lugol-iodine staining. The results obtained showed that the frequency of Chlamydia trachomatis infection in the group of patients considered was comparable with that previously reported on other groups. Male patients showed a higher infection rate than females. Different percentages of positivity were obtained in patients with gonococcal infection and in those with post-gonococcal urethritis.
