Abstract

A survey on the prevalence and distribution of antibodies to BLV was performed by the agar-gel immunodiffusion test over a period from 1983 to 1985. More than 2,407 serum samples were collected from Holstein cattle raised in the eastern part of Saitama prefecture where suburban dairy farm is operated. The average positive rate of this period was 4.9%. The rates of reactive samples varied from 2.6 to 9.8% among the age groups of cattle from younger than one year to 14 years of age. The positive rate increased gradually with age. The positive rates also varied widely from 0 to 21% among areas surveyed. Furthermore, there were large differences in this rate among farms even in the same area. The results were interpreted and discussed in connection with the enzootic feature of BLV infection.

1983년(年)부터 1985년도(年度)까지 사이에 일본(日本) Saitama현(縣) 각소도시근교(各小都市近郊)의 낙농장(酪農場)에서 사육(飼育)되는 2,407두(頭)의 유우(乳牛)를 대상(對象)으로 BLV(bovine leukemia virus) 감염여부(感染與否)를 혈청학적검사(血淸學的檢査)(agar-gel immunodiffusion test)를 실시(實施)한 결과(結果) 평균양성율(平均陽性率)은 4.9%이었고, 연령(年齡)이 증가(增加)함에 따라 2.6%에서 부터 9.8%까지 양성율(陽性率)이 있으며, 동일지역(同一地域)에서도 조사낙농장별(調査酪農場別)로 양성율(陽性率)은 큰 차(差)가 있었다. 본조사연구(本調査硏究)의 결과(結果)를 BLV감염(感染)에 대한 수의역학적(獸醫疫學的) 기초자료(基礎資料)로 제시(提示)하는 바이다.
