Tissue protozoa play a significant role as a cause of economic losses in reproductive and productive aspects in camels beside the zoonotic importance. A Cross-sectional study was designed to estimate the seroprevalence and risk factors of Toxoplasma gondii and Neospora caninum in dromedary camels in Matrouh and Aswan border governorates of Egypt. One hundred and eighty-two serum samples from apparently healthy dromedary camels and tested serologically for neosporosis and toxoplasmosis. The prevalence of possible related risk factors was investigated from December 2020 to November 2021. The serological testing of 182 camel serum samples revealed a prevalence (15.93%, 29/182) for Neospora caninum, (58.24%, 106/182) for Toxoplasma gondii and (9.34%, 17/182) for both infections together. The total seroprevalence rate was (64.84%, 118/182). Camels in Matrouh governorate were at high risk (p < 0.05) of infection with tissue protozoa 3.74 times more than camels in Aswan governorate. Maghrabi camels were found more significant (p < 0.05) prevalent for T. gondii infection (62/78, 79.49%) by 5.28 times than Sudani camels, Otherwise, in Sudi camels, N. caninum is almost 2.70 times Maghrabi camels. The results showed that age and sex were mostly significant for N. caninum and T. gondii. This study found that, camels are a possible source of infection for the studied tissue protozoa, some of which are significant for public health. More research are needed to describe their true situation and epidemiology in dromedary camels.
