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

improved method for recovery of ascarid and other nematode eggs from soil, emphasis on Baylisascaris procyonis and Toxocara cati

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

Trypanosoma brucei in Peromyscus maniculatus, erythrocyte pathologic changes and phagocytosis, light and electron microscopic studies

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

Dermacentor andersoni, demonstration of Anaplasma marginale in hemolymph by animal inoculation and fluorescent antibody technique

Sarcoptes scabiei var. suis, ivermectin, single treatment of infected sows before farrowing eliminated scabies from sows and prevented its transmission to their offspring, offspring remained uninfected throughout study regardless of whether they were treated with ivermectin at weaning, infection (epizootic) in growing pigs could be controlled by single treatment of all in-contact pigs but routine treatment of all pigs at weaning does not seem justified

Dermacentor andersoni, density, size, type, and distribution of colonies of Anaplasma marginale in gut of ticks incubated at 37 C for various periods

Sarcocystis odocoileocanis, S. odoi n. sp., and Sarcocystis sp. found in muscles of white-tailed deer, measurements, ultrastructure; cat fed Sarcocystis-infected meat from deer shed sporocysts 24 days later which probably belonged to S. odoi n. sp.
