SEROLOGIC EVIDENCE OF LEPTOSPIROSIS IN A SOUTHERN ARIZONA COYOTE POPULATION 1

Histologic examination of kidney tissue from a morbid coyote (Canis latrans) suggested a leptospiral infection. Sera from nine wild coyotes captured subsequently in the same general area were tested by the rapid plate agglutination method. Four of nine sera contained antibodies to Leptospira canicola, while one serum also contained antibodies for L. icterohaemorrhagiae. Epidemiology and morbidity are discussed.
