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

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

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

Rhipicephalus simus, 5 types of Anaplasma marginale colonies demonstrated in midgut

Amblyomma hebraeum, percentage and rate of female attachment to rabbits was higher (except shortly after release of females) around feeding males than in areas previously treated with extract of fed males, effect of elapsed time and of number of males vs. equivalent extract on attachment values, results prove bioassays to be valid for component and extract-equivalent assessment

Moniezia sp. in naturally infected calves on pasture, fenbendazole efficacy at three dosage levels: Georgia

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.
