Abstract
Streptococcus agalactiae (S. agalactiae) is a microorganism that asymptomatically colonizes the female genital and gastrointestinal tracts of humans. It produces infections in extreme ages of life and in pregnant women. The case of an adult male is presented, with frequent heterosexual intercourse with different partners. He consulted for itching and burning in the penis' glans. His partner had marked vaginal dryness as a result of early ovarian failure. The patient had ulcerative, non-painful, erythematous lesions with raised edges and little yellow-green discharge. No Donovan bodies were found in the discharge smear and the culture was positive for S. agalactiae. His asymptomatic partner had negative microbiological tests. Both with negative serologies for Chlamydia, HIV and syphilis. No information was obtained from other sexual contacts. It cannot be ascertained that it was a venereal event, it is more likely that the injuries are related to repeated coital trauma.

Resumen
Streptococcus agalactiae (S. agalactiae) es un microorganismo que coloniza asintomáticamente el tracto genital y gastrointestinal femenino de los seres humanos. Produce infecciones en edades extremas de la vida y en mujeres embarazadas. Se presenta el caso de un varón adulto, con frecuentes relaciones heterosexuales con diferentes parejas. Consultó por picazón y ardor en el glande del pene. Su pareja tenía una sequedad vaginal marcada como resultado de una insuficiencia ovárica precoz. El paciente presentaba lesiones ulcerosas, eritematosas, indoloras, con bordes elevados y escasa secreción de color amarillo verdoso. No se encontraron cuerpos de Donovan en el frotis de descarga y el cultivo fue positivo para S. agalactiae. Su pareja asintomática tuvo pruebas microbiológicas negativas. Ambos con serologías negativas para clamidia, VIH y sífilis. No se obtuvo información de otros contactos sexuales. No se puede determinar que fue un evento venéreo, es más probable que las lesiones estén relacionadas con traumatismos coitales repetidos.
