All immunized chickens shown high HI antibody titers (9Log2) two weeks post-booster dose. The chickens were then challenged using homogenous AI H9N2 strain. During the course of infections, oropharyngeal and cloacal swabs were collected from all chickens at 3, 5 and 7 days post...

Results demonstrate that chickens developed detectable HI antibody titers up to 6log2 within two weeks post-booster vaccination. The challenge experiment was performed using isolate A/chicken/Egypt/A6/2011 (H5N1) with concentration of 105 EID50 to evaluate the protective efficacy of the Egy-H5 plasmi...

DAS-ELISA and immuno-blotting were used for evaluating the induced antisera. Results: Antisera for CYSDV and CVYV were produced efficiently and used for virus diagnosis through DAS-ELISA, DBIA, and TBIA. RT-PCR confirmed the nature of the two viruses.
