donkeys which is characterized by the death and the expolsion of fetus

Virus abortion which was described by Dimock in 1940 has been recognized in the United States of America(l), Jugoslavia, Austria, İtaly, Germany (20), Hungary (13), Bulgaria (15), and South Africa (14), it is a,
particular hazard in horse breeding establishments.
The cause of the disease is avirus which may be present in the tissues
of the fetus, in the placenta, and in the fetal fluid. it has been demonstrated
that the agent of equine virus abortion İs similar to or identical with the
equine influenza virus (13,7). Equine influenza and equine virus abortion
are only different terms for an infection with the same virus. Depending
on their resistance naturally infected animals first of all show a more or
less acute clinical picture of influenza after an incubation period of 3-7
days. Abortion foııows 14-76 days after infection. The preceding influenza
stage on account of its frequent mild course often remain unııoticed. Crossimmunization: anima! experiments and the .compIement fixation reaction
getting positive ten days after infection conferm the identity of the viruses,
which considered responsible for two different diseases(
