Effect of selected anthelmintics on three common helminths in the brown pelican (Pelecanus occidentalis).

The effect of selected anthelmintics (albendazole, fenbendazole, piperazine dihydrochloride and clorsulon) against three major helminths (Contracaecum multipapillatum, Mesostephanus appendiculatoides, and Phagicola longus) were studied in 29 brown pelicans (Pelecanus occidentalis). Albendazole and fenbendazole were highly effective against all three parasites. Clorsulon had moderate effect against M. appendiculatoides and poor effect against C. multipapillatum and P. longus. Piperazine dihydrochloride had no effect against these helminths.

Relationship between blood iron parameters and trichinellosis in swine.

Reduced levels of total iron binding capacity and unsaturated iron binding capacity were observed in the blood of trichinous and iron-injected trichinous pigs. No change was observed in their serum iron and saturation concentration levels. Also, reduced iron concentration levels were observed in the livers of trichinous pigs, while increased iron concentration levels were observed in the spleens of trichinous pigs and the livers and spleens of iron-injected pigs. No difference was found with regard to weight gains, number of larvae per gram of tissues, or histologic characteristics of 'nurse cells'.

Unusual psammoma bodies in an extracranial syncytial meningioma from a dog. A light and electron microscopic study.

An epidural neoplasm was removed from the right side of the third cervical vertebra of a Blue Tick Hound dog. By light microscopy the tumor was classified as a syncytial meningioma containing psammoma bodies that were histochemically positive for calcium salts, but negative for reticulum fibers and collagen. Ultrastructurally, the tumor cells had numerous processes and desmosomes. Cytoplasmic fibrils were sparse. Coated cytoplasmic vesicles frequently were fused with plasma membranes. The psammoma bodies were not within the cytoplasm, but were in spaces continous with the extracellular space. The bodies were composed of a medium electron-dense matrix; a crystalline, highly electron-dense center; and, sometimes, short fibrils embedded in the glanular matrix.

Bilharziasis in a Nanday conure.

Natural infection with a schistosome in a pet Nanday conure caused weight loss, blood-flecked diarrhea, and death. Hemorrhagicoulcerative colitis and cloacitis were found at necropsy. The schistosome was not identified but was believed to be Gigantobilharzia sp.

Gastrointestinal parasitism of Iowa coyotes in relation to age.

Taenia sp., Physaloptera sp., Ancylostoma caninum, Toxascaris leonina, and/or Trichuris vulpis were recovered from gastrointestinal tracts of 141 and 144 (97.9%) coyotes ranging from 1/2 to 8 1/2 years of age. Ancylostoma caninum exhibited a significant decline in both prevalence and mean number per coyote with increasing age of the host. Taenia sp. appeared with consistently high prevalence in all age classes. Physaloptera sp. and T. leonina showed general reductions in prevalence in all age classes. Physaloptera sp. and T. leonina showed general reductions in prevalence and mean nubmer with increasing host age, although the data were not statistically significant. Coccidia were found in 15 of 58 (25.9%) fecal flotations.
