Najimudeen, Shahnas Infectious Bronchitis Coronavirus Infection in Chickens: Multiple System Disease with Immune Suppression 2020-09-24 .txt text/plain 6966 349 37 The evolution of new strains of IBV during the last nine decades against vaccine-induced immune response and changing clinical and pathological manifestations emphasize the necessity of the rational development of intervention strategies based on a thorough understanding of IBV interaction with the host. For example, chickens infected with certain strains of IBV such as Mass, QX-like strain or Aust T at ages of 1-14 days develop cystic oviducts without impaired ovarian functions, which leads to false layer syndrome with no egg production [15, [63] [64] [65] . One of the immune cell types that bridges innate and adaptive host responses is the macrophages, and the available data show that certain IBV serotypes (i.e., Mass and Conn) target respiratory tract macrophages and replicate within them, thus leading to a productive infection [59, 88] . ./cache/cord-331020-lyxje82u.txt ./txt/cord-331020-lyxje82u.txt
