Coccidial infection is universal in sheep and goats, and coccidiosis can be a significant problem in the young of both species. The coccidian are members of the protistan phylum Apicomplexa, subclass Coccidiasina, intracellular parasites, characterized at some stage of the life cycle by a typical apical complex of organelles at one end of the organism. Members of the genus Eimeria and Isospora ...

Coprological examination of New Caledonian geckoes of the genus Rhacodactylus Fitzinger, 1843 revealed two new species of coccidia. Isospora leachiani sp. n. from R. leachianus (Cuvier, 1829) has oval, colourless oocysts, measuring 21-26 x 16-18.5 microm. Sporocysts are ellipsoidal, 11-12.5 x 6.5-8 microm, with distinct Stieda and substieda bodies. Oocysts of Isospora sykorai sp. n. from R. cil...

One group of kids (n = 23) was given 2 x 10(5) oocysts of Eimeria ovinoidalis (sheep coccidia) at birth; a second group (n = 23) was kept as an uninoculated control. Body weights, E ninakohlyakimovae oocyst output and serum coccidial antibody levels were monitored up to 77-102 d of age. No significant difference in any of these parameters was seen between the 2 groups, suggesting that no immune...

Parasitic gastro-enteritis leads to a serious health threat with a limitation to the productivity of small ruminants due to the associated morbidity, mortality, cost of treatment and prophylaxis (Nwosu et al., 2007). Parasitic infections are of much economic importance because small ruminants' rearing has become a major source of income particularly to the marginal farmers in the country (Patha...

Neospora caninum is a protozoan parasite of animals, which before 1984 was misidentified as Toxoplasma gondii. Infection by this parasite is a major cause of abortion in cattle and causes paralysis in dogs. Since the original description of N. caninum in 1988, considerable progress has been made in the understanding of its life cycle, biology, genetics and diagnosis. In this article, the author...

Three of 6 female long-clawed shrews, Sorex unguiculatus Dobson, 1890, collected on the island of Hokkaido, Japan, were found to have unsporulated oocysts and sexual stages (both macro- and microgamonts) in varying stages of development of an unidentified coccidium in both lactating and nonlactating mammary glands. Gamonts developed in the alveoli of the mammary glands, and oocysts were found i...

BACKGROUND Coccidiosis is an intestinal disease caused by protozoal parasites of the genus Eimeria. Despite the advent of anti-coccidial drugs and vaccines, the disease continues to result in substantial annual economic losses to the poultry industry. There is still much unknown about the host response to infection and to date there are no reports of protein profiles in the blood of Eimeria-inf...

The aim of the study was to determine level parasitic infections in West Pomeranian European bison on basis coproscopic examinations. A total 172 faecal samples from Mirosławiec, Drawsko and Jałowcówka herds were examined by flotation sedimentation methods as well Baermann technique. Faecal examinations revealed presence gastrointestinal nematode eggs belonging family Trichostrongylidae genera ...
