Perianal streptococcal dermatitis (PSD) is an uncommon superficial cutaneous infection of the perianal area, almost exclusively described in children and mainly caused by group A streptococci. We report here a case of PSD caused by Streptococcus dysgalactiae subsp. equisimilis, Lancefield group G, in an adult man due to heterosexual oral-anal sexual contact.

A case of heterosexual transmission of Moraxella catarrhalis by fellatio, which resulted in acute purulent urethritis mimicking gonorrhoea in the male partner, is described. In male patients with urethritis due to M. catarrhalis, orogenital contact with a sexual partner carrying the organism in his/her oropharynx is the probable route of transmission.
