Abstract
This study was carried out on slaughtered sheep and goats in different slaughter houses in Sharkia Province to determine the prevalence of ovine and caprine Sarcocystis infection and effect on some biochemical clinical pathological parameters.
Parasitological examination of faecal samples revealed presence of eggs of internal parasites in 25(41.67%) lambs(less 9 month) {12(48%) nematodes, 7(28%) trematode ) & 6(24%) mixed infection} 29 (48.33%) adult (more 2 year) ( sheep {15(51.72%) nematodes,10 (34.48%) trematode & 4(13.79%) mixed infection},19 (47.50%) young goats {11(57.89%) nematodes, 5(26.32%) trematode & 3(15.79%) mixed infection}, 24 (60%) adult goats{14(58.33%) nematodes, 5(20.83%) trematode &5 (20.83 %) mixed infection}.
Serologically, antibodies against Sporocystis spp. infection were observed in sheep serum samples were 47.50% (57) & 40% (32) for goats serum samples. The infection in adult animals were {34 (56.67%) in sheep and 19 (47.50%) in goats} more than in young animals {23 (38.33%) in sheep and13 (32.50 % in goats}. Sarcocystis in sheep distributed as macrocystis (16.67% for young and 11.67% adult), microcystis ovi-cans (10% young, 5% adult) and mixed infection (macrocystis and microcystis) were (56.67% young, 38.33% adult), meanwhile in goats Sarcocystis macrocystis (25% young and 15% adult), microcystis (capricans) (15% young,12.5% adult) and mixed infection (macrocystis and microcystis) 47.50% for young, 32.50%for adult).
Sarcocystis infection in Sheep and goats induced a significant decrease in leukocytic count, monocytes, total protein, albumin, globulin, lymphocytosis, neutrophilia, non significant effect in basophils and eosinophilis beside significant rise AST,ALT& ALP.
It could be concluded that the Sarcocystis spp infected both sheep and goat, the infection in adult were more than in young ones. Sarcocystis induces changes in biochemical parameters. Therefore, it has of great importance the human to be trained not to feed their dogs and cats with uncooked meat, and abattoir remnants were burned to be effectively broken of infection cycle between the intermediate and the definitive hosts.
