Abstract


Ewes are polyoestrous seasonal animals, however in order to increase their fertility, progesterone derivatives are used by means of impregnated sponges with 20 mg of fluorogestone acetate (FGA). Nevertheless, the use of sponges with FGA generates vaginitis, erythema and interferes with fertility. This paper studies the effect of FGA and sponge over the microbiota vaginal in ewes anestrous. To obtain experimental samples, fifteen ewes anestrous were used. Five ewes were used as control group. Ten ewes anestrous were used and data were collected before, withdrawal and 56 h after withdrawal of sponges with and without FGA, in order to quantify, identify and evaluate changes in the vaginal bacterial microbiota. In the normal microbiota were found Escherichia and Klebsiella strains; however, after removal of the devices, were found enteropathogenic coliform bacterias and some opportunistic as Shigella, Enterobacter, Citrobacter, E. coli, Pseudomonas and Acinetobacter. Also found that the device without FGA, induces a change in the vaginal microbiota, thus, causes vaginitis. In vitro sensitivity tests were performed on the strains identified using twelve different antibiotics; the results showed a higher sensibility to enoxacin, then to the trimethoprim-sulfamethoxazole, ceftriaxone, chloramphenicol and ampicillin. Antibiotics use is necessary to prevent the vaginitis in ewes with dispositive. In conclusion, the intravaginal sponges promote of the vagina inflammation and produce coliform bacteria in vagina.
