Serum samples of 30 chickens per flock from 6 grand parent stock (GPS) farms and 70 parent stock (PS) farms were collected for seroprevalent study of pullorum disease-fowl typhoid (PD-FT) infection by serum plate agglutination test (SPA). The incidence of PD-FT infection in GPS flocks and PS flocks were 0% and 15.7%, respectively. Especially PS flocks infected with PD-FT showed age dependent patterns that 22.2% of flocks between 20 to 30 weeks of age and 38.9% of flocks between 30 to 40 weeks of age were positive.
