Toxoplasma antibody prevalence in veterinary personnel and a selected population not exposed to cats.

To further elucidate the epidemiologic factors involved in the transmission of Toxoplasma gondii from cats to humans, veterinarians, animal hospital workers and a selected population of non-contact subjects were questioned about rural or urban residency, pets owned, contact with cats and whether their cats used a litter box in the house. Sera samples were tested at 1:128 dilution for toxoplasma antibodies using indirect fluorescent and hemagglutination techniques. None of the 60 non-contact individuals were seropositive.

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.
