ResumoHE virus of infectious laryngotracheitis (LT) produced cytopathogenic effect (CPE) and plaques in chick-embryo fibroblast and respiratory epithelium.1 However, Buthala, et a.3 was unable to find CPE with LT virus in chick-embryo kidney cells, although the virus proliferated in the cell culture. The present study had three objectives: 1. to study the effect of LT virus in chick-embryo kidney cells and its ability to produce CPE and plaques, 2. to attempt the isolation of the virus by plaque method from chickens artificially or naturally infected with LT virus, 3. to study the differences between plaques formed by LT virus, chick-embryo-lethalorphan (CELO) virus and Newcastle disease (ND) virus.
