Taenia taeniaeformis, cats (exper.), parasite longevity and productivity

Toxoplasma gondii, goats, prevention of abortion and neonatal death by vaccination with nonpathogenic coccidium Hammondia hammondi

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

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

Ixodes (Afrixodes) matopi n. sp. is described from females and males collected off twigs bearing deposits of intraspecific communication marks secreted by the pre-orbital glands of the klipspringer Oreotragus oreotragus and from laboratory-reared immature specimens. One female was also found on a goat. The 4 collections were all from Zimbabwe, 3 of them from Matabeleland South Province and the fourth from Inyanga District, Zimbabwe.

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 occultans n. sp. originally obtained from engorged female Hyalomma marginatum rufipes collected from cattle in Northern Transvaal, transmission studies in laboratory strain of ticks and splenectomized cattle, morphological, serological, and cross-immunity studies distinguished parasite as previously undescribed species highly infective for H. marginatum rufipes but of low virulence in cattle, unsuccessful attempt to transmit transovarially with Boophilus microplus

isoenzyme patterns of extracts of adult schistosomes collected from Hippopotamus amphibius in Kruger National Park compared with similar extracts of adult Schistosoma mansoni and S. rodhaini, characteristics differed suggesting that H. amphibius schistosome is separate species

Theileria mutans, 4 isolates obtained from geographically distant parts of South Africa by subinoculation of infected blood were readily transmitted to cattle by Amblyomma hebraeum, all attempts to transmit these isolates with Rhipicephalus appendiculatus were unsuccessful

attempts to transmit Anaplasma marginale to cattle with field collections of Hippobosca rufipes were unsuccessful, 1 of 3 attempts to transmit organism with Stomoxys calcitrans was successful
