Toxoplasmosis is a globally prevalent protozoan parasitic disease of livestock, among others, with significant zoonotic potential. This study aimed to assess the seroprevalence of Toxoplasma gondii antibodies in serum samples from water buffaloes (Bubalus bubalis) in Sohag governorate, Upper Egypt. In addition, several factors related to animals, management, and environment were analyzed to identify the risk factors for T. gondii infection. A cross-sectional epidemiological approach was employed, with samples collected from various locations across the region and tested using a commercially available indirect enzyme-linked immunosorbent assay (iELISA). Animal and environmental factors were evaluated to identify potential risk factors for the disease. The overall seroprevalence of T. gondii among the tested buffaloes was 7% (24/342). Seasonal variations were observed, with the highest seropositivity recorded in spring (10.7%; 11/103), followed by autumn (8%; 2/25), summer (5.6%; 7/125), and winter (2.2%; 2/89). High seropositivity was detected in aborted females, at 19% (4/21), and in repeated breeders, at 10.5% (4/38), in relation to buffaloes showing anestrus (no positive cases), although the differences were not statistically significant. Our findings suggest that T. gondii is endemic in Sohag, with water buffaloes serving as sentinel animals for the disease. The spring season appears to be a risk factor for infection. Further studies are needed to assess the potential risk to humans, particularly regarding the consumption of raw or undercooked buffalo meat infected with T. gondii.
