Abstract:

Toxoplasmosis is one of the most common parasitic infections that affect both human and warm-blooded animals. The infection is caused by Toxoplasma gondii, an obligate protozoan that is found to be prevalent worldwide. Human contraction occurs through ingestion of the infective stage of T. gondii which came from food and drinks contaminated with oocysts acquired from exposure to felines, which act as a definitive host. Infection in gallus domestics is an important indicator of soil contamination and aids in the identification of the epidemiology of the parasite. This study sought to determine the presence of Toxoplasma gondii in different parts of chickens which are intended for human consumption. Histopathological technique was utilized to detect the presence of the morphological form of the parasite in four female chickens raised for four months in free-range and caged conditions. Based on the findings, there was no presence of Toxoplasma gondii in 39 histopathologic slides obtained from organs of the chickens intended for human consumption. The study indicated that regardless of raising confinement of the chickens there was no Toxoplasma gondii seen and reported.
