The antibody titer of 202 chickens to SA-11 rotavirus was determined by enzyme-linked immunosorbent blocking assay. The chickens were from 15 separate flocks on six farms. The titer was detectable (1:18 or greater dilution) in 43% of the chickens. The wide variation in infection rate between flocks on individual farms (0% to 90%) indicated there is probably not significant transmission of the virus between flocks on the farm. Significant differences in numbers of serotest-positive birds were found between separate farms, possibly reflecting different management practices.
采用酶联免疫吸附阻断试验测定了202只鸡对SA - 11轮状病毒的抗体效价。这些鸡来自六个农场的15个不同鸡群。43%的鸡可检测到抗体效价（稀释度为1:18或更高）。单个农场内不同鸡群之间的感染率差异很大（0%至90%），这表明农场内不同鸡群之间可能不存在病毒的显著传播。不同农场之间血清检测呈阳性的鸡的数量存在显著差异，这可能反映了不同的管理方式。
