Abstract

Outbreaks of paralytic syndrome affecting chicken aged between 2-8 months were reported in Morogoro. The syndrome caused mortalities as high as 75% especially so in the younger stock. It was diagnosed as Marek’s disease by the clinical signs, gross pathology, and histopathology and virus isolation via the yolk sac and chorioallantoic membrane (CM) of embryonated chicken eggs. Both birds examined had both neural and visceral forms of Marek’s disease. Light to massive lymphocytic infiltration was observed in nerves and visceral organs. Of the 13 suspected birds, 8 gave positive results to viral isolation using yolk sac and chorioallantoic routes
