Distribution épidémiologique du virus de la Bronchite infectieuse aviaire autour du monde
Abstract
Infectious bronchitis virus (IBV) is ubiquitous in most parts of the world where poultry are reared. A large number of IBV variants exist worldwide; some being unique to a particular area, others having a more general distribution. The purpose of this review is to give an update on IBV strains currently circulating in commercial chickens worldwide and present a clear picture of the relationship between many of these viruses.
