Seroprevalence of Toxoplasma gondii in Chickens (Gallus domesticus) in Sudan

Toxoplasma gondii (T. gondii) infections are widely prevalent in human beings and animals worldwide. Humans become infected post-natally by ingesting tissue cysts from undercooked meat, consuming food or drink contaminated with oocysts or by accidentally ingesting oocysts from the environment.
The present study was conducted to determine the seroprevalence of T. gondii infections in chickens in Sudan, during the period between December 2015 and January 2016.
Sera were separated from blood samples, which were collected from the wing vein of chickens (n = 58). Commercial serum agglutination kits (toxoplasmosis latex test kit) for Toxoplasma antibodies detection, using diluted blood serum samples (1/2, 1/4, 1/8, 1/16, 1/32, 1/64), were used.
Twenty-five, seventeen and sixteen chicken sera from river Nile, Khartoum and Sennar states, were positive, respectively. These represented a seroprevalence of 100% in all states with different titers.
Toxoplasma gondii infection is prevalent in chickens of Sudan. Therefore, further investigations on the parasite in other States of Sudan is important.
