Twenty-six coyotes (Canis latrans) collected in Florida, U.S.A., were examined for parasites. Nine species of helminths (1 trematode, 1 cestode, 6 nematodes, and 1 acanthocephalan), 1 species of biting louse, and 2 species of ticks were identified. Dirofilaria immitis (43%), Ancylostoma caninum (33%), Physaloptera rara (29%), and Taenia pisiformis (24%) were the most prevalent helminths. Macracanthorhynchus ingens is reported from coyotes for the first time, and Spirocerca lupi is reported in coyotes from Florida for the first time. Ectoparasites collected included the biting louseTrichodectes canis and the ticks Amblyomma maculatum and Dermacentor variabilis. A coyote infected with 66 D. immitis had evidence of chronic pulmonary arteritis and medial hypertrophy of pulmonary aterioles.
