Infectious Bronchitis Virus in Asia, Africa, Australia and Latin America - History, Current Situation and Control Measures
ثبت نشده
چکیده
Infectious bronchitis virus (IBV) is ubiquitous in most parts of the world where poultry are reared and is able to spread very rapidly in nonprotected birds. It is shed via both the respiratory tract and the faeces and can persist in the birds and faeces for several weeks or months. Although strict biosecurity and working with a one-age system are essential control measures, normally vaccination is an essential tool to increase the resistance of the chickens against challenge with IBV strains. This paper presents an overview of the history and current situation of IBV in Asia, Africa, Australia and Latin America, including the control measures necessary to control it.
