Description

Seroepizootiological studies were conducted on rearing horses on the Hidaka Rearing Farm, Japan Racing Association, over a period from 1980 to 1983. Antibodies against equine herpesvirus type 1 (HH-1 subtype), Getah virus (MI-110 strain), equine adenovirus (T-1 strain), and rotavirus (Lincoln strain of Nebraska diarrhea virus) were examined by the complement fixation test. Antibody against equine rhinovirus type 1 (NM-11 strain) was demonstrated by the virus neutralization test. Equine rhinovirus was considered to have spread most widely, as most of the horses examined showed a significant increase in titer of antibody in the winter. Equine adenovirus also presented a high positive rate at admission to this farm in 1981 and 1982. The rate of infection after admission differed from one year to another, ranging from 4 to 20%. Against rotavirus, 14 to 40% of horses had antibody at admission. And only 1 or 2 horses were infected every year. With equine herpesvirus type 1 the antibody positive rate at admission and infection rate differed among every year. In horses admitted in 1980, the positive rate at admission was 5% and the infection rate about 50% over a period from June to July, 1981. In horses admitted in 1981, both rates were very low. In horses admitted in 1982, the antibody positive rate was 47% at admission, but none were infected during the rearing period. No outbreak of Getah virus infection was observed during these studies, except that several horses introduced from Aomori Prefecture had antibody at admission.
