Abstract
Infectious bursal disease viruses were isolated from broiler chickens experiencing proventriculitis in, for example, Oklahoma, Texas, West Virginia, and California. Chicken virus isolates Texas RB 3, Texas RB 4, HBS, F57-7, W/L 39, GAR 1, and the like have been isolated. These viruses are some of the major causes of this condition and can be utilized as or in a vaccine to prevent the disease condition. The viruses are a significant finding in the search for a causative agent for proventriculitis in broiler chickens and as such may be utilized in the development of a vaccine or vaccines. The viruses can be attenuated to be used as a modified live vaccine or utilized in an inactivated form in a killed vaccine.
