[Prostato-urethritis due to chlamydia].

One of the etiological agents of urethritis and prostatitis is Chlamydia trachomatis which reveals obligatory intracellular parasitism. Patient specimens (smears of the urethra, urine, first portion, expressed prostatic fluid, ejaculate) are centrifuged onto special cell cultures, so-called McCoy cells, and induce characteristic cytoplasmatic inclusions. Giemsa staining or DNA-binding fluorochromes (DAPI or Hoechst 33258) are suitable procedures to identify chlamydia inclusions. Serologic tests to establish infections due to Chlamydia trachomatis are only of limited diagnostic value.
