Virulent IBD tentatively diagnosed in California
A strain of infectious bursal disease was diagnosed for 13 week old pullets in California, and was responsible for killing up to 30% of the flock.
A report at IPE by the Association of Veterinarians and Egg Production revealed that samples showed characteristics of virulent IBD strains.
Similar strains have been seen in Europe in the 1980’s, and investigations continue to look for the cause of the outbreak. This strain of IBD is rare for the U.S., but has been responsible for severe losses in Asia, Europe, and Africa. It has also been found in broiler-producing areas in Brazil, Colombia and Venezuela.
