The most frequent problems in horses reproduction are generally divided into
those of infectious and non infectious etiology. Common causes of infectious
diseases are usual?ly viruses and bacteria, and less frequently protozoa,
mykoplasma and fungi. In this work there are presented the most important
fact about sexually transmitted diseases, their clinical picture, risk
factors, preventive measures as well as measures to prevent and eradicate the
diseases. The biggest risk factor for sexually transmitted diseases in horses
are breeding stallions, both in natural mating and in artificial
insemination. Therefore, in order to prevent genital infections in horses, it
is essential that the stallions used for breeding are healthy (non-infected).
That can be determined with certainty only if the stallions are examined
(tested) just before the breeding season on most frequent sexually
transmitted diseases (CEM,EAV). It is well known that in most cases the
clinical picture of sexually transmitted diseses is not manifested on
genitals. As well, variations in clinical picture can be expected also in
mares, depending on the stage of the disease and its etiology. Harms arising
from sexually transmitted diseases can be divided into direct and indirect.
Direct damage occurs in the form of endometritis, miscarriage, stillbirths
and births of weak foals, and indirect in restricting the traffic of infected
and suspicios animals, isolation of the infected ones as well as medical
treatment and interrupting mating.
