Chlamydia trachomatis associated with chronic dysuria among patients with Schistosoma haematobium.

ABSTRACT

Eighty-seven Egyptians with Schistosoma haematobium infection (current or past) and chronic dysuria seen at the Theodor Bilharz Research Institute outpatient urology clinic in Imbaba, Cairo, Egypt were investigated for Chlamydia trachomatis infection. Direct fluorescent antibody tests (DFAT) showed 30 urethral swabs (35%) and 40 urine sediments (46%) were positive for Chlamydia. Indirect fluorescent antibody testing showed 29 (34%) serum samples and 25 (29%) urethral smears were positive for Chlamydia. There was a highly significant association between patients with active Schistosoma infection and those with urine and urethral specimens positive for Chlamydia by DFAT (P < 0.01).
