Pathogenicity of Czech Isolates of Infectious Bursal Disease Virus

Juranová, R. , Nguyen Thi Nga, L. Kulíková, V. Jurajda: Pathogenicity of Czech Isolates of Infectious Bursal Disease Virus. Acta Vet. Brno, 2001, 70: 425-431. An epidemics of infectious bursal disease (IBD) affected chicken farms in the Czech Republic in the mid nineties. Characteristics of six strains of infectious bursal disease virus (IBDV), isolated from broiler chickens, lying hybrid pulle...

Pathogenicity Study and Restriction Enzyme Profile of a Recently Isolated Infectious Bursal Disease Virus in Iran

The pathogenicity of a recent isolate of Infectious bursal disease virus (IBDV), IR499, isolated from a nonvaccinated flock with 17.5 % mortality rate in susceptible SPF chickens, chickens embryos and broilers was discussed. The molecular characterization of the virus based on the restriction fragment length polymorphism (RFLP) pattern was also investigated. The mortality rates were 85% and 22%...

Characterization of a Highly Virulent Infectious Bursal Disease Virus

Comparison of Pathogenicity and Serologic Response of Four Commercial Infectious Bursal Disease Live Vaccines.

Various commercial vaccines for immunization of broiler chickens against infectious bursal disease (IBD) are available, so it would be appropriate to compare the pathogenicity and immune response of chickens to these vaccines. In this study the pathogenicity and serologic response of four IBD vaccines, cloned D78®, Bursine-2®, Bursimune® and Cevac Gambo-L®, were evaluated in specific pathogen f...

Infectious Bursal Disease: Pathogenicity and Immunogenicity of Vaccines

The Infectious Bursal Disease (IBD) is a contagious viral disease that affects young chickens and may cause high morbidity and mortality. As the virus is very resistant to the environment, vaccination is required in case of high infection pressure. Due to variations in the virulence degree of the vaccines available to control IBD, this study aimed at evaluating the pathogenicity and immunogenic...
