Strongylus vulgaris, establishment of patent infections in 6 of 8 helminth-free ponies given adult worms via nasogastric tube, removal of worms from cecum and ventral colon of donor horses, initial appearance of eggs in feces and maximum egg counts of recipients, percentage survival of adults after intragastric inoculation determined at necropsy

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

Dirofilaria immitis adults, dogs (exper.), effect of therapy with prednisolone vs. aspirin on pulmonary thromboembolism caused by thiacetarsamide treatment, scanning electron and light microscopy

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.

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

influence of parasitemia level of calves at time of feeding by Dermacentor andersonii upon development of Anaplasma marginale in the ticks

trimethoprin-sulfadiazine in the horse, serum, synovial, peritoneal, and urine concentrations after single-dose intravenous administration

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

Sarcocystis alceslatrans, dogs fed moose musculature shed sporocysts in feces, endogenous development in small intestine, ultrastructure of oocyst and sporocyst walls during sporogony, intestinal inoculation; coyote and cats fed sarcocyst-infected moose meat did not pass oocysts or sporocysts in feces

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
