Adult toxocaral infection with focal retinal lesion.

Twelve patients, one of whom was homosexual, attended with a contact note indicating that their partner had been treated for gonorrhoea; three were advised to attend by their contacts; four came for a check-up (one had had a contact who was being treated for salpingitis); three had noticed genital warts; and two complained of itchiness (one with scabies, and one with pediculosis pubis). No patient had had antibiotic treatment in the preceding three months. On examination six patients (three of those with a contact note, one who had come for a check-up, one who had been sent by a contact, and one who had genital warts) were found to have a urethral discharge of which they had been unaware. Urethral samples were obtained from all the patients by sterilized platinum loops for Gram-stained slides and microscopical examination, and a further sample was inoculated on to a Columbia blood agar plate without antibiotics. Five patients did not return for followup examination and may have remained infectious.
