common internal helminths of swine, flubendazole, dose range and efficacy studies

The male, female, nymph, and larva of Haemaphysalis (Rhipistoma) norvali sp. n., are described and compared with other members of the H. (R.) spinulosa group. Adult H. (R.) norvali parasitize the southern African hedgehog, Erinaceus frontalis Smith, in Matabeleland, Zimbabwe. Immatures were reared on a laboratory rabbit.

Strongylus vulgaris, pony foals (nat. and exper.), effectiveness of fenbendazole against later fourth stage larvae assessed by larval motility and studies of cranial mesenteric, ileocolic, and celiac arteries

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

helminths and arthropods collected from warthogs at monthly intervals, prevalence, rainfall and temperature data, clear patterns of seasonal abundance could be determined only for Physocephalus sexalatus and Haematopinus phacochoeri

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

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
