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

Abstract

Background: 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. Objectives: 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. Methods: 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. Results: 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. Conclusions:Toxoplasma gondii infection is prevalent in chickens of Sudan. Therefore, further investigations on the parasite in other States of Sudan is important.

Meat-Borne Parasites a Health Hazard Concern in the Sudan: A Review

“…A study was conducted in 3 states of the Sudan (Khartoum, River Nile and Sennar) in cages and free range chickens. Seroprevalence for T. gondii antibodies was 68/68 (100%) examined samples [41].…”

“…Chicken toxoplasmosis was recorded for the first time in the Sudan this year 2016 [41]. A study was conducted in 3 states of the Sudan (Khartoum, River Nile and Sennar) in cages and free range chickens.…”
