| Abstract |
|
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. The incidence of GPS flocks and PS flocks using Salmonella (S.) gallinarum 9R (SG9R) live vaccine were 33.3% and 58.6%, respectively. The sero-positive rate of 11 flocks were 6.7-83.3% by SPA and 2.9-55.6% by enzyme linked immunosorbent assay (ELISA), and ELISA showed more lower antibody levels than SPA. Furthermore, specific antibodies produced by SG9R vaccination were detectable by SPA using SG9R antigen without cross-reaction with the PD-FT infection. |
