The incidence of hemorrhagic enteritis (HE) infection in California turkeys was studied by testing 2220 turkey blood samples from 173 flocks for HE virus (HEV) antibody by the enzyme-linked immunosorbent assay (ELISA). Maternal antibody was detected at 1 day of age in all flocks tested, and it vanished after 3 weeks. Acquired HEV antibody appeared at 8 to 10 weeks, and 100% of the meat and breeder turkey flocks were positive after 11 weeks of age. HEV infection occurred earlier in the meat flocks than in the breeder flocks, and it also occurred earlier during summer than during the fall and winter months.
通过酶联免疫吸附测定（ELISA）对来自173个鸡群的2220份火鸡血液样本进行检测，研究了加利福尼亚火鸡出血性肠炎（HE）感染的发生率。在所有检测的鸡群中，1日龄时均检测到母源抗体，3周后消失。获得性HEV抗体在8至10周时出现，11周龄后100%的肉用火鸡群和种用火鸡群呈阳性。HEV感染在肉用火鸡群中比在种用火鸡群中发生得更早，并且在夏季比在秋冬季节发生得更早。
