cytopalsmic inclusions
Ebola Virus
Filoviridae
RNA
Most important cause of viral abortions in horses and is enzootic in horse populations worldwide. Can also cause respiratory disease and encephalomyelitis. Abortions usually are sporadic and affect only 1 female, but extensive outbreaks can occur if exposed to fetus
nucelar inclusions
Equine Abortion Virus
EHV-1
herpesviridae
DNA
Most natural infections are sympotmatic. Fever, leukopenia, depression, excessive lacrimation, anorexia, uticaria of head, neck, and trunk and edema, which is most pronounced over the eyes. Most horses sporadically recover, but foals can die due to rapid bronchostitial pneumonia
