在弗拉萨拉索塔县的12个地点，哨兵鸡群监测了虫媒病毒的传播，从1978年到1988年。 在此期间，分析了3，452份血清样本的圣路易斯脑炎病毒（SLE）和东部马脑脊髓炎病毒（EAE）的血凝抑制抗体。 总体而言，91只鸡血清转化为SLE，3只鸡血清转化为SLE。 SLE的传播强度呈现出相当大的年与年的变化。 来自南部县鸡群的鸡比在北部县饲养的鸡更容易血清转化为SLE病毒。 中部县哨兵的SLE血清转化率介于南北县之间。 鸡被关在四个栖息地类型：橡树吊床，斜线松树锯棕榈地区，牧场，城市居民区。 不同生境间SLE血清转换率无显著差异。
Sentinel chicken flocks monitored arboviral transmission at 12 sites in Sarasota County, Fla., from 1978 through 1988. During this time, 3,452 serum samples were analyzed for hemagglutination inhibition antibody to St. Louis encephalitis virus (SLE) and eastern equine encephalomyelitis virus (EEE). Overall, 91 chickens seroconverted to SLE and three to EEE. The intensity of SLE transmission showed considerable year-to-year variation. Chickens from south-county flocks were more likely to seroconvert to SLE virus than chickens maintained at the north-county sites. The SLE seroconversion rate for midcounty sentinels was intermediate between north- and south-county sites. Chickens were caged in four habitat types: oak hammocks, slash pine-saw palmetto areas, pastures, and urban-residential areas. There was no significant difference in SLE seroconversion rates between habitats.
