Resumen
El cuerpo humano está colonizado por una gran cantidad de microbios, los cuales de manera colectiva se les llama microbiota humana. La relación entre ellos y la salud humana ha sido de gran estudio en los últimos años.
A nivel vaginal, la presencia de estos microorganismos se ha correlacionado con el mantenimiento de un ecosistema vaginal dinámico y propio de prevenir la colonización e infección por organismos patógenos oportunistas. El pH vaginal estable de las mujeres en etapa reproductiva se mantiene gracias a los estrógenos, el glucógeno y los lactobacilos, debido a su producto de ácido láctico.
Dichos lactobacilos favorecen la respuesta inmunitaria y combaten la colonización del epitelio periureteral por uropatógenos.
Este ecosistema vaginal se puede alterar por diversos mecanismos intrínsecos del húesped o por factores externos como la ingesta de antibióticos, prácticas intravaginales, alimentación o tabaco.
La importancia de mantener un ecosistema vaginal estable radica en evitar las infecciones vaginales y sus eventuales complicaciones.
