Sera from 19 (5.6%) of 338 coyotes (Canis latrans) collected in Los Angeles County, California between 1986 and 1990 had antibodies against Yersinia pestis using the passive hemagglutination test. Coyotes were excellent sentinels of plague activity in Los Angeles County. Enzootic plague declined dramatically in the county during the 5-yr period.
1986年至1990年间在加利福尼亚州洛杉矶县采集的338只郊狼（犬属）中，有19只（5.6%）的血清通过被动血凝试验检测出含有抗鼠疫耶尔森菌的抗体。郊狼是洛杉矶县鼠疫活动的优秀哨兵。在这5年期间，该县的动物间鼠疫大幅下降。
