Infectious Laryngotracheitis

Wednesday, September 13, 2017

(NY) Infectious laryngotracheitis (ILT – herpesvirus) associated with respiratory signs was confirmed by histopathology (intranuclear inclusions) following necropsy of a 3-month old chicken from a multi-age and multi-species flock of 50 that were all showing respiratory distress. Gross lesions of a caseous exudate blocking the proximal trachea was typical of ILT.
