Antibacterial and antifungal activity of the human endometrial fluid during the natural cycle

EFA presented two antimicrobial activity patterns: (a) one common to all the samples, exhibiting activity against and lack of activity against and , and (b) an individualized pattern, showing activity against some of the other microorganisms tested. The intensity of antibacterial activity differs between EFA samples. Our data suggest that the uterine microbiota is controlled by means of endometrial fluid components.
