sarcocystosis causing death in calf immediately after birth, rosette and palisade configurations of merozoites in schizonts observed in histologic sections of gray and white matter from cerebrum; encephalitis, to lesser extent meningitis, and necrosis of cerebrum, cerebellum, and brain stem; calf's dam probably was exposed to infective cysts in feed or water contaminated by feces from carnivores

Strongylus spp. and other parasites of equids (natural infections), controlled tests with fenbendazole in multiple doses at two dose levels

Ascaris suum, Trichuris suis, naturally infected 10-week-old female pigs, anthelmintic activity of ivermectin administered subcutaneously or orally

Toxocara canis, cynomolgus macaques (exper.), visceral larva migrans, hematologic and serologic changes, neurologic signs, diminished growth rates, diagnostic antibody titers in enzyme-linked immunosorbent assay, severe granulomatous hepatitis and encephalomyelitis, no ocular lesions, basis for clinical interpretation and diagnosis in humans

3 hybridoma-produced monoclonal antibody cell lines elicited against Eimeria tenella sporozoites showed various degrees of reactivity with the other intracellular developmental stages, all inhibited sporozoite-host cell penetration and coccidial development in vitro

pharmacokinetics of [3H]levamisole in pigs after oral and intramuscular administration

Trypanosoma brucei in Peromyscus maniculatus, pathogenesis (hematologic, erythrocyte biochemical, and iron metabolic aspects)

gastrointestinal nematodes in calves (exper.) causing severe anemia, effect on preparation of carrier erythrocyte ghosts and erythrocyte survival

Amblyomma hebraeum, percentage and rate of female attachment to rabbits was higher (except shortly after release of females) around feeding males than in areas previously treated with extract of fed males, effect of elapsed time and of number of males vs. equivalent extract on attachment values, results prove bioassays to be valid for component and extract-equivalent assessment
