Title: Sero-prevalence of Toxoplasma gondii in Sheep at Khartoum State
Author: Dafallah, Esraa Hassan Ahmed
Abstract: Background: Toxoplasmosis is a parasitic protozoan disease caused by an organism belongs to genus Toxoplasma, which can infect all warm blood animals. Globally, human infection is very high, expressing asymptomatic latent infections, or a clinical disease involving lymph nodes, Ocular, or central nervous system. Cats are the final host and sheep become infected from cat’s faeces. In Sudan consumption of raw e.g. (MARARA) or under cooked meat, poise a real threat for transmission of the disease. The objectives of the study were to detect the sero-prevalence of Toxoplasma gondii in sheep by identifying it`s rate and to know the prevalence of human toxoplasmosis in Sudan. Methodology: A descriptive, cross-sectional study was conducted where sixty samples of serum were statistically collected at ante-mortoum from sheep at Alkadro slaughterhouse, in a period of 4 weeks – (from March to April/ 2017). In each week 15 sera samples were taken for analysis at the Central Veterinary Laboratory at Soba, using Latex Agglutination Test (LAT) and examined for the specific T. gondii IgG antibodies. Result: The sero-positive sheep for Toxoplasma gondii in this research was (27 of the 60) 45%, which is a very high rate of infection. Since sheep at slaughterhouses are brought from different places of Sudan, the result might indicate the situation in the Sudanese sheep herd in general. No records of the disease in humans were found at federal ministry of health. Conclusion: The study proved the high presence of Toxoplasma infection in sheep. Experimentally it was proven that cooking meat above 55-60°C and keeping meat cold below 10°C prevents the transmission of this parasite to humans. Therefore, people should refrain from eating raw or under cooked meat. Maintaining meat hygiene is also important as well as proper getting rid of cat’s wastes from sheep residence followed by keen hand washing afterwards.
