IDENTIFICATION AND CHARACTERIZATION OF NOVEL LIVE ATTENUATED VACCINE STRAINS OF INFECTIOUS LARYNGOTRACHEITIS by

Development of an Attenuated Live Virus Vaccine against Sheep Pox

Differentiation of field isolates and vaccine strains of infectious laryngotracheitis virus by DNA sequencing.

Two different regions of the infected cell protein 4 (ICP4) gene of infectious laryngotracheitis virus (ILTV) were amplified and sequenced for characterization of field isolates and tissue culture-origin (TCO) and chicken embryo-origin (CEO) vaccine strains. Phylogenetic analysis of the two regions showed differences in nucleotide and amino acid sequences between field isolates and attenuated v...

Replication Kinetic of Infectious Laryngotracheitis Virus in Embryonic Chicken Neural Stem Cell

Background and Aims: Infectious laryngotracheitis virus (ILTV) infection causes a highly contagious respiratory disease in poultry leads to significant economic losses in the poultry industry. The genomic and antigenic characteristics between virulent and vaccine strains of ILTV are very similar. The ability of embryonated chicken neural stem (CNS) cell for differential diagnosis of ILTV strain...
