o EHV 1(also abortion and encephalitis),
o EHV 4 (equine rhinopneumonitis)
o influenza virus
o *equine arteritis virus
o equine rhinitis virus A (Apthousvirus)
o equine rhinitis virus B (Erbovirus)
o equine adenoviruses 1 and 2
Viruses associated with multisystemic infections (generalized)
o equine infectious anemia (EIA) virus o equine arteritis virus (EAV), also abortion o FAD o African horse sickness (FAD) o Hendra virus
Viruses associated with neurological infections
o WNV; WEE, EEE, VEE (see LT 10B)
o EHV1 (also abortion and respiratory)
o rabies (see LT10A)
o Borna disease virus
Viruses associated with skin and mucosa
o VSV (vesicular stomatitis virus) o EHV3 (equine coital exthema) o papilloma viruses
Viruses associated with Reproduction
o EHV 1, EAV, EHV 4 (rare)
Viruses associated with Enteric
o rotaviruses
o adenovirus 2
o Toroviruses (Coronaviridae) e.g. Berne virus
repsiratory disease, late term abortions, abortion storms in herds neurologic signs, EHM
Equine Abortion Virus, EHV-1
herpes viridae
profuse serous nasal discharge, common in foals, rarely associated with abortions, DNA virus
EHV-4; Equine rhinopneumonitis virus
herpes
self limiting vesicular, ulcerative lesions of genital mucosa and surrounding skin, occasionally on lips, muzzle, teats
EHV-3 equine coital exanthema
herps
Horse presents with fever, thrombocytopenia, icterus, edema w. reoccuring episodes
Equine Infectious Anemia Virus
Retroviridae; lentivirus
Carried by stallions, repiratory/repro disease, fever depression, lacriamtion, spread via macrophages, abortions
EAV- equine arteritis virus
Arteriviridae
FMD like lesions, but this is a horse soo oyu think its>
VSV
severe systemic dz and pulmonary and cardiac forms high mortality
African horse sickness
Reoviridae; orbivirus
Neurologic signs, generalized ill, to encephalitis, neg RNA
West Nile Virus

Neurologic Disease pos RNA
EEE, VEE, WEE
pos RNA to ddx from WN
