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

This is the first extensive survey of metazoan parasites (particularly of the roundworm Baylisascaris procyonis) from the intestines of raccoons in British Columbia. The sample collected in 1997-1998 consisted of 82 raccoons that had been sick or had been killed accidentally by automobiles. Fifteen parasite taxa were found: 3 nematodes, 9 digenetic trematodes, 2 acanthocephalans and 1 cestode. Ten of these parasites constitute new host records for raccoons, including 4 digenetic trematodes that have been reported in marine birds and mammals on the Pacific Coast of North America. Baylisascaris procyonis infected 61% of the raccoons with a mean intensity of 27. The high rate of infection indicates a large potential for environmental contamination and, thus, human and animal exposure to infectious eggs. Prevention of larva migrans is discussed, particularly for people in contact with raccoons in wildlife rehabilitation centers.

Experimentally red beet (Beta vulgaris L.) extract had been used to stain different types of parasites Lecithochirium acutum (Trematoda), Taenia spp.Dipylidium caninum and cysticercus cyst for Taenia spp. (Cestoda), Toxascaris leonina and Toxocara canis (Nematoda) and Neoechinorhynchus iraqensis (Acanthocephala). Stained helminthes were acquired a good pigmentation with distinction their internal structure, fish's Trematoda Lecithochirium acutum appear well –defined of its internal structure, the oral and ventral sucker, cirrus sac, uterus, testes, ovary and vitallaria were appeared pink in color. The whole of mature and gravid segments of Taenia spp. were acquired the yellow to brown colour in both cirrus sac and vas deference besides differentiation of eggs in gravid segment, Scolex of Taenia spp. get brown in color.in addition segment of Dipylidiun caninum acquired yellow colour. The cysticercus cyst was taken pink in color with distinguish of its hooks, while both Toxascaris leonina, Toxocara canis and Neoechinorhynchus iraqensis were appear pink to red in colour
