Resumen

:La colonización del colon en humanos por espiroquetas fue descrita por vez primera en el año 1967 por Harland y Lee, relacionada con pacientes que presentaban diarrea y rectorragias1.

:Las especies de espiroquetas encontradas hasta el momento2 son Serpulina pilosicoli y Brachyspira aalborgi, cuya infección se caracteriza por una clínica inespecífica, diarrea persistente, dolor abdominal, rectorragias o deposiciones purulentas.

:Los escasos datos acerca de la prevalencia de esta colonización varían desde el 2,5-9% en Europa al 64% de la India3, y en todos los grupos estudiados es mayor entre los varones homosexuales. Los mecanismos de transmisión son desconocidos por el momento, y el único tratamiento efectivo es el metronidazol. A continuación se describen tres casos de pacientes diagnosticados de espiroquetosis colónica en nuestro hospital.

:Large intestine infection due to spirochetes was described in 1967 and is mainly related to two pathogens, Serpulina pilosicoli and Brachyspira aalborgi. Clinically, infection presents as diarrhea and/or rectorrhagia and is more frequent among homosexuals. Its prevalence is difficult to estimate but significant differences have been described according to the socioeconomic level of the area studied. We describe three cases of diarrhea due to spirochetes, which are of interest due to the lack of published cases in Spain. Based on these cases, we describe the main characteristics (morphological, therapeutic, etc.) of this infection.
