Sarcocystis species : a possible threat to cattle health and food safety in South Sinai governorate, Egypt

الملخص EN

Sarcocystis is a zoonotic worldwide cyst-forming coccidian parasite.

the study aimed to determine the frequency of Sarcocystis infection in ruminants in south Sinai, identify Sarcocystis spp.

and geno-types that can infect these animals using molecular techniques.

a total of 353 blood samples were collected from ruminants to molecular screen for Sarcocystosis using two PCR assays targeting Sarc-cattle and Sarc-sheep genes amplified 600 BP & 1100 BP, respectively.

the results showed that goats and sheep didn't have Sarcocystis infection, whereas Sarcocystis infection was in cattle with its risk pathogenesis.

the demonstrated cattle Sarcocystosis was in 44 / 113 (38.94%), but neither among 172 sheep nor 68 goats.

the recovered sequences were deposited in the GenBank under the accession number MZ 197780 as S.fusiformis and MZ 197784, MZ 197785, MZ 197786, and MZ 197787 as S.cruzi.
