strongyles (predominantly cyathostomes), mares and their foals, dynamics of transmission studied on pastures previously free of parasites, fecal egg counts beginning day of parturition and based on time of year, relationship between weather conditions and pasture larval counts, necropsy findings in two foals: Texas

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

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.

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

helminths of Thoroughbred horses with emphasis on stomach worms and tapeworms, numbers and infection rates according to host age and month of necropsy

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

Sarcocystis spp. in infected meat from ox, sheep, goats, moose, elk, and mule deer fed to raccoons, none shed Sarcocystis sporocysts in feces
