Abstract

The study aims to investigate Marek\'s disease (MD) incidence rate among the morbidus clinical layer fowl using, clinical examination, necropsy and histopathological profile. Clinically and necropsy examination of birds showed sever nervous signs similar to those of MD without evidence of any pathognomic nervous lesion, while acute diffused lymphomatosis were demonstrated in the visceral organs. Furthermore, histopathological pleomorphic lymphoproliferations detected in the visceral organs were confirmed MD infection with 27.3% incidence rate of the clinical and pathological examined layers. According to these findings further investigation of the disease with final diagnosis of the virulent serotypes in the study area is needed for control polices.
