Abstract :
THE PREVALENCE of anti-Toxoplasma gondii antibodies was investigated in goats slaughtered for food in various areas of the Giza province, Egypt. Two hundred and thirty blood samples collected from the slaughtered goars were used for the serologic diagnosis of T. gondii infection by the modified agglutination test (MAT) with cut-off value 1:25. The antibodies to T. gondii were found in 44.3 % (102/230) of goat sera. Experimental infection of goats with the infective stages of both locally isolated and RH strains of T. gondii was carried out. Persistence of T. gondii tissue cysts and lesions were demonstrated in the different tissues and organs of the experimentally infected goats by the histo-pathological examination. This study is the 1st assay of toxoplasmosis in Egyptian goats by MAT and is the unique successful determination of the T. gondii infective stages within the experimentally infected goat tissues by the histo-pathological examination. Consequently the finding results obtained scope the public health significance of goat meat as source of human infection
