heartworm-infected dogs (infected by transplantation of adult worms), pulmonary arterial disease following use of adulticide (thiacetarsamide) modified by aspirin or prednisolone, arteriographic study

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

Strongylus spp. and other parasites of equids (natural infections), controlled tests with fenbendazole in multiple doses at two dose levels

Sarcocystis capracanis, pregnant dairy goats immunized with a subclinical dose of sporocysts and subsequently challenged with lethal doses, concluded that: i) subclinical dose given in early pregnancy can cause fetal death without causing clinical disease in doe; ii) abortion can occur prior to development of 2nd-generation meronts; and iii) Sarcocystis-induced immunity is impaired during pregnancy

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

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

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

Theileria parva lawrencei, effect of halofuginone lactate against tick-induced infections in splenectomized Bos taurus, persistence of piroplasms in 3 out of 4 recovered animals

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
