Guidelines for the Control of Equine Viral Infections	2010-04-23		.txt	text/plain	3364	253	53	At least twenty‐eight of the fifty‐eight viruses induce clinical disease but the range of syndromes is limited; eleven provoke respiratory symptoms and eleven cause encephalitis. There is possibly one Coronavirus infecting horses; Ditchfield (1969) isolated a virus from a Thoroughbred with undifferentiated respiratory disease and found that it possessed a morphology similar to that of infectious bronchitis virus of poultry, the type-virus of the Coronavirus group. Equine infectious anaemia virus probably belongs to the Oncornavirus group, i.e. the RNA tumour viruses. Eleven of the thirty-four known vector-transmitted viruses cause disease and vaccines have been developed against six of them (Table VII) . Seventeen of the twenty known viral contagions of horses cause disease and vaccines have been developed against five of them (Table VIII ). At least twenty-eight of the fifty-eight viruses induce clinical disease but the range of syndromes is limited; eleven provoke respiratory symptoms and eleven cause encephalitis. The vector-transmitted virus diseases are best controlled by prophylactic vaccination.	./cache/cord-009702-02bo7pnl.txt	./txt/cord-009702-02bo7pnl.txt
