Echinococcus multilocularis, cats are less suitable than dogs as definitive hosts

levamisole toxicity in pigs was enhanced by nicotine-like compound (pyrantel) but was not affected by organophosphate (dichlorvos)

Schistosoma edwardiense recovered from hippopotamus, measurements of adults and eggs, species validity, determined to be hippopotamus-specific based on examination of game droppings for schistosome eggs and on lack of experimental establishment in rodents, Biomphalaria salinarum believed to be intermediate host based on evidence from experimental exposure; S. hippopotami suggested to be synonymous with S. mansoni

Babesia bigemina infection in population of Boophilus decoloratus cannot be eliminated in short term by treating cattle prophylactically with imidocarb dipropionate, Babesia retained by ticks for at least complete generation

Ostertagia ostertagi, beef cattle, acquisition of inhibited larvae during winter and spring, efficacy of ivermectin against inhibited early 4th-stage larvae of O. ostertagi and other nematodes of abomasum and intestinal tract: Louisiana

Babesia bovis, cattle, kinetics of specific indirect fluorescent antibody test titers and total serum IgG and IgM values after vaccination and challenge exposure, nonspecific suppression of total IgG and IgM values coinciding with period of peak parasitemia

Theileria? taurotragi, probable cause of death of 4 calves with cerebral theileriosis: Transvaal

Parafilaria bovicola, general appearance, size, developmental times, and site of development of each larval stage in potential vector flies (Musca xanthomelas and M. lusoria)

Amblyomma hebraeum, 60CO irradiation of nymphs failed to attenuate Cowdria ruminatium

Echinococcus multilocularis, dogs and cats (both exper.), efficacy of praziquantel; cats are not as suitable as experimental hosts for this parasite as are dogs
