Dhinakar Infectious bronchitis virus: immunopathogenesis of infection in the chicken 2007-11-12 .txt text/plain 12530 665 45 While infectious bronchitis (IB) is considered primarily a disease of the respiratory system, different IBV strains may show variable tissue tropisms and also affect the oviduct and the kidneys, with serious consequences. Nevertheless, the lack of correlation between antibodies and resistance, discrepancies between in vitro strain differentiation by VN tests and in vivo cross-protection results (Darbyshire, 1985) and re-excretion of virus in the presence of high titres of circulating antibodies (Jones & Ambali, 1987) all suggest that while humoral antibodies play a role in recovery from IBV infection, other immunological mechanisms are involved. Comparison of the susceptibility of chicks of different ages to infection with nephrosis-nephritis causing strain of infectious bronchitis virus Challenge experiments to evaluate cross-protection induced at the trachea and kidney level by vaccine strains and Belgian nephropathogenic isolates of avian infectious bronchitis virus Effects of avian infectious bronchitis virus (Arkansas strain) on vaccinated laying chickens ./cache/cord-304278-0qy1nngs.txt ./txt/cord-304278-0qy1nngs.txt
