| Abstract: |
| 1975~1984年对仔猪季节感染变动与人群乙脑发病强度进行十年观察。结果表明乙脑流行年仔猪感染率高,半数感染阳转日出现的早及抗体滴度几何均数高等为其特点。结合本地区提出每年7月中旬至8月上旬作为检测时段,不仅能进行可靠的近期预测预报,同时也有助于对乙脑防治成效作出客观评价。讨论了检测点可能代表的范围及作为检测扩散宿主成猪或仔猪优劣问题。 |
| English Abstract: |
| A survey of seasonal change in infection rate of piglets and incidences of Japanese B encephalitis (JBE) was carried out in Linfen, Shanxi Province, during the period of 1975-1984. It was found that infection rate of JBV of the piglets was high, 50% positive HI reaction of serum of piglets appeared early and geometric mean HI antibody titer was also high during the epidemic year. The results indicated that from the middle July to early August each year, reliable prediction could be made and the effect of the prevention of JBV could be evaluated. |
