Postulados de Koch

Robert Koch, uno de los pilares de la bacteriología, formuló una serie de criterios fundamentales para determinar la relación entre un microbio y una enfermedad específica. Estos criterios, conocidos como los postulados de Koch, establecen que un organismo patógeno debe cumplirse varias condiciones para ser considerado como causante de una enfermedad.
