Cytauxzoon felis, susceptibilities of (i) domestic cats to inoculation with infected bobcat blood and ground tissues; (ii) domestic cats to subinoculation with blood from cats having received bobcat blood; (iii) inoculated cats to subsequent challenge exposure with deep-frozen virulent inoculum of domestic cat origin; and (iv) eastern bobcat to reinoculation with various doses of virulent Cytauxzoon inoculum of domestic cat origin; additional experiments to determine if piroplasm levels in bobcats and domestic cats could be raised to maximize chances for further transmission of Cytauxzoon to domestic cats

Sarcocystis cruzi, calves fed sporocysts of 2 different isolates from coyotes, number of merozoites in peripheral blood, duration of parasitemia, and extent of multiplication of merozoites

Sarcocystis cruzi, newborn calves (exper.), correlation of development of Sarcocystis with the resulting lesions

Dermacentor andersoni, transmission of Anaplasma marginale to splenectomized calves by injection of gut homogenates from incubated vs. non-incubated adult ticks

Cytauxzoon felis, susceptibilities of bobcats, 4 species of domestic farm animals, 9 species of laboratory animals, and 17 wildlife species to infection using infective material from domestic cats, Lynx rufus floridanus developed cytauxzoonosis with signs and lesions identical with those of domestic cats and died of disease, Lynx rufus rufus developed subclinical persistent parasitemia, results indicate that both species of bobcats may serve as reservoir hosts; sheep developed low persistent parasitemia without clinical signs, while other species of animals failed to produce evidence of cytauxzoonosis
