Prevalence of Dirofilaria immitis in a stray dog population in western New York.
In a survey in 1973 undertaken to determine the prevalence of Dirofilaria immitis in 100 dogs from a public pound in western New York, 2 dogs were found to be positive. Microfilariae of Dipetalonema sp were not present. Hearts and pulmonary blood vessels were dissected for adult worms, and blood samples were examined for microfilariae, using a modified Knott technique. Although adult heartworms and microfilariae have been recovered from wild foxes, coyotes, and wolves in New York, this is the first report of heartworm in domesticated dogs in the state.
