Abstract
Neosporosis is a parasitary disease that affects
dogs, cattle, sheep, goats, buffaloe, deer and
horses, caused by Neospora caninum, an
intracellular protozoan. This parasite can infect
wild and domestic canids, the ruminants and
the horses. Dogs (Canis lupus familiaris) and
coyotes (Canis latrans) are definitive hosts of
the protozoan, and this fact suggests that the
agent can infect the cattle´s food with oocysts
eliminated by these animals in their feces. The
vertical transmission is known as responsible for
the perpetuation of the infection within the herd,
and this is why chronically infected cows transmit
the parasite to the fetus during the gestation
as a consequence of the recrudescence of
the latent infection, which appears due to the
immunosupression caused by the gestation.
Abortion is the only clinical sign oberved in
adult cows, but living calves with the infection,
congenitally transmitted, can be found. They
have low weight when they are born and they
also show neurological signs, such as ataxia. The
most important effect of neospirosis in cattle is
the occurrence of abortions, with the economic
loses they bring to producers. This is why the
identification of the risk factors involved in the
infection of cattle with Neospora caninum has
important consequences in the development
of strategies to control or prevent the disease,
especially when there are no treatments or
vaccines available.
