在日本赛马协会的两个训练中心对表现出临床发热的马进行了血清流行病学研究，每个训练中心保持1，200至2，100匹赛马进行训练。从1980年到1985年，它继续澄清发热的原因，以便考虑采取措施预防传染病。6年来，共有3849匹马被发现患有发热症。对2852匹马进行了马疱疹病毒1型（EHV-1）、马鼻病毒1型（ERhV-1）、轮状病毒和马腺病毒（EAdV）的血清学检测。结果，669匹（23.5%）马对这些病毒表现出血清转化;即，491匹（73.4%）对EHV-1，91匹（13.6%）对ERhV-1，64匹（9.6%）对轮状病毒，23匹（3.4%）对EAdV。EHV-1、ERhV-1和轮状病毒的传播具有季节性。EHV-1和轮状病毒在冬季和早春传播。ERhV-1不仅在寒冷的季节传播，而且在季节变化的时间，如早春和初秋。3岁马的EHV-1血清转化率是其他病毒血清转化率的2倍。所有显示对ERhV-1和EAdV血清转化的马分别在4岁或3岁以下。表现出对EHV-1、轮状病毒、ERhV-1和EAdV血清转化的马的平均年龄分别为2.96、2.73、2.44和2.25。
A sero-epizootiological study was conducted on horses which showed clinical pyrexia at two training centers, each of which maintained 1, 200 to 2, 100 racehorses for training, of the Japan Racing Association. It continued from 1980 to 1985 to clarify the cause of pyrexia, so that measures might be considered for the prevention of infectious disease. A total of 3, 849 horses were found to be affected with pyrexia for the 6 years. Of them, 2, 852 horses were tested to equine herpesvirus type 1 (EHV-1), equine rhinovirus type 1 (ERhV-1), rotavirus and equine adenovirus (EAdV) by collecting paired serum samples. As a result, 669 (23.5%) horses showed seroconversion to these viruses; that is, 491 horses (73.4%) to EHV-1, 91 (13.6%) to ERhV-1, 64 (9.6%) to rotavirus and 23 (3.4%) to EAdV. EHV-1, ERhV-1 and rotavirus exhibited a seasonal characteristic in spread. EHV-1 and rotavirus spread in winter and early spring. ERhV-1 spread not only in the cold season, but in changing times of season, such as early spring and early autumn. The percentage of 3 years old in the horses showing seroconversion to EHV-1 was two times higher than those in the horses showing seroconversion to other viruses. All of the horses showing seroconversion to ERhV-1 and EAdV were under 4 or 3 years old, respectively. The mean age of the horses showing seroconversion to EHV-1, rotavirus, ERhV-1 and EAdV were 2.96, 2.73, 2.44 and 2.25, respectively.
