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.

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

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

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

small and large strongyles, ponies, cambendazole, effects of periodic therapeutic dosing (1974-1978) on strongyle egg counts and on mares' reproductive performance with teratologic implications, critical test, comparison of benzimidazole-resistant species of small strongyles in 4 populations

Dirofilaria immitis, dogs (exper.), clinical, hematologic, arteriographic, radiographic, and morphologic responses to dying heartworms following treatment with the adulticide thiacetarsamide

Babesia bovis, cell culture-derived vaccine administered to yearling heifers, immunologic protection against challenge, immune recognition manifested by anamnestic humoral response to challenge

Boophilus microplus engorged females stored at 4 C for up to 5 days and females kept at room temperature for 1 day and then at 4 C for 1 day showed no significant differences in their response to an organophosphate (dioxathion) as determined by the Drummond adult test

Rhipicephalus kochi, synonymy, description of female, male, nymph, and larva, scanning electron microscopy, brief report of laboratory life cycle study, review of host records and zoogeography in Africa, differentiation from R. pravus, R. punctatus, and R. appendiculatus

Babesia bovis, B. bigemina, cattle, effect of tick control on infection rates and on enzootic stability, survey of farms from 6 geographical regions, control of ticks is not justified economically as means of minimizing risks of babesiosis outbreaks unless regular dipping is necessary to limit damage done by ticks per se
