Abstract

Infectious Laryngotracheitis (ILT) is a viral respiratory disease of poultry caused by Gallid herpesvirus 1 leading to severe economic losses. The aim of the current study was to isolate and identify ILT virus in suspected outbreaks of one broiler flock (farm 1) and three layer flocks (farms 2,3 and 4) located in Tripoli. Samples of trachea were collected and preserved in transport media for viral isolation and some were preserved in 10% neutral formalin for histopathology. Broiler and Layer flocks were serologically monitored and tested for the presence of antibodies by ELISA against ILTV at first days old and later at slaughter age for broilers and before the onset of production for layers in which total of 290 blood samples were collected from six poultry farms (3 broiler flocks and 3 layer flocks).
