Abstract:

Toxoplasmosis is one of the most common diseases prevalent in the world, caused by a coccidian parasite Toxoplasma gondii which infects humans, animals and birds. Poultry consider reliable human source of food in addition it is considered an intermediate host in transmission of the disease to humans. Trails of isolation of local T. gondii chicken strain through bioassay of the suspected infected chicken tissues in mice was carried out and the isolated strain was confirmed as being T. gondii using Polymerase Chain Reaction (PCR). Seroprevalence of antibodies against T. gondii in chicken sera in six Egyptian governorates were conducted by enzyme linked immune-sorbent assay (ELISA) using the isolated chicken strain antigen. Moreover, comparison between the prevalence rates in different regions of the Egyptian governorates were been estimated. Isolation of local T. gondii chicken strain was accomplished from chicken tissues and confirmed by PCR technique. The total prevalence rate was 68.8% comprised of 59.5, 82.3, 67.1, 62.2, 75 and 50% in El Sharkia, El Gharbia, Kafr El sheikh, Cairo, Quena and Sohag governorates, respectively. The prevalence rates were higher among Free Range (FR) (69.5%) than commercial farm Chickens (C) (68.5%); while, the prevalence rate was less in Upper Egypt than Lower Egypt governorates and Cairo. This study is the first was used antigen from locally isolated T. gondii chicken strain for the diagnosis of chicken toxoplasmosis. The higher seroprevalence particularly in free range chickens (house-reared) refers to the public health importance of chickens as source of zoonotic toxoplasmosis to human
