in dromedary camels () in Egypt: a comparative seroepidemiological study in Upper and Lower Egypt.

Abstract

Toxoplasmosis remains a prevalent parasitic zoonosis worldwide, raising public health concerns. The global information available regarding the role of camels in the epidemiology ofis still limited. This study aimed to assess the seroprevalence ofin dromedary camels () from northern and southern Egypt. A total of 513 serum samples were obtained from camels across Cairo (Lower Egypt) and Aswan (Upper Egypt) governorates. The Modified Agglutination Test (MAT) was performed to screen for anti-antibodies. The overall seroprevalence was 13.84% (71/513; 95CI%:10.85-16.83). The bivariate analysis showed that animals aged 4-8&#x202f;years (13.84%, 36/260) and older than 8&#x202f;years (18.45%, 31/168) showed significantly higher seropositivity compared to those young individuals (&#x2264; 4&#x202f;years old) (&#x202f;=&#x202f;0.011). Additionally, the multiple logistic regression analysis highlighted the geographic region as a potential risk factor forexposure. Thus, camels from Lower Egypt had significantly higher seroprevalence of(19.92%, 51/256) compared to those from Upper Egypt (7.78%; 20/257;&#x202f;<&#x202f;0.001; odds ratio [OR]&#x202f;=&#x202f;2.94; 95% CI: 1.70-5.10). Our results provide evidence of moderate, widespread, and heterogeneous spatial distribution ofamong camel populations in Egypt, which might have important implications for animal and public health in that country. Surveillance and control programs should be implemented to reduce the risk of exposure ofin camels.
