A study was conducted to determine the pattern of St. Louis encephalitis (SLE) virus activity in the avian populations of the Los Angeles metropolitan area in 1986. In total, 679 birds of 42 species were captured at 7 study sites. The overall prevalence of SLE neutralizing (N) antibody of 3% indicated enzootic transmission. Antibody prevalences were higher in birds sampled in the central part of the metropolitan area, which was consistent with other epidemiologic data. The use of specific avian species as sentinels for future surveillance of SLE virus activity was suggested.
1986年开展了一项研究，以确定洛杉矶大都市区鸟类群体中圣路易斯脑炎（SLE）病毒的活动模式。在7个研究地点共捕获了42种679只鸟。SLE中和（N）抗体的总体流行率为3%，表明存在动物间传播。在大都市区中部采样的鸟类中抗体流行率更高，这与其他流行病学数据一致。有人建议使用特定鸟类作为未来SLE病毒活动监测的哨兵。
