2002 MAR 6 - (NewsRx.com & NewsRx.net) -- The molecular keys to the serious poultry disease, known as Gumboro disease, have been discovered for the first time by scientists of the University of Maryland Biotechnology Institute and the Virginia-Maryland Regional College of Veterinary Medicine.
At UMBI's Center for Agricultural Research (CAB), virologist Vikram N. Vakharia and colleagues reported finding specific amino acid residues in the Gumboro-causing viruses that are responsible for its infection, virulence and disease development in poultry.
In the late 1980s, concern was heightened in the poultry industry of the Delmarva (Delaware/Maryland/Virginia) Peninsula when researchers found new strains of infectious bursal disease virus (IBDV) that causes serious disease. The region produces more than 600 million broiler chickens annually. The IBDV strains found there caused wasting away of the bursa, which is the major immunological organ of chickens, but did not cause the hemorrhaging condition and high death rates of earlier, so-called classic, strains found in the United States in the 1960s. However in the 1990s, strains of IBDV emerged in Europe and Asia that killed up to ...
