Cultivo de tejido del duodeno

Definición:

Es una prueba de laboratorio para examinar un fragmento de tejido tomado de la primera parte del intestino delgado (duodeno) en búsqueda de organismos causantes de infecciones.

Forma en que se realiza el examen:

La muestra se envía luego a un laboratorio y se coloca en un plato especial (medio de cultivo) el cual permite que las bacterias o virus proliferen. La muestra se coloca bajo un microscopio y se revisa a intervalos regulares para ver si hay algún tipo de microorganismos presentes y si éstos se están multiplicando.

Luego, se identifica cualquier microorganismo que prolifere en el cultivo.
