Growth Kinetics and Transmission Potential of Existing and Emerging Field Strains of Infectious Laryngotracheitis Virus
Attenuated live infectious laryngotracheitis virus (ILTV) vaccines are widely used in the poultry industry to control outbreaks of disease. Natural recombination between commercial ILTV vaccines has resulted in virulent recombinant viruses that cause severe disease, and that have now emerged as the dominant field strains in important poultry producing regions in Australia. Genotype analysis usi...
متن کاملReplication 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...
متن کاملMolecular biology of avian infectious laryngotracheitis virus.
Infectious laryngotracheitis virus (ILTV) is an alphaherpesvirus that causes an economically important chicken disease, which results in delayed growth, reduced egg production, and also frequently in death of the animals. After acute infection of the upper respiratory tract, the virus can establish latency in the central nervous system, and subsequent reactivations can lead to infection of naiv...
متن کاملDifferentiation 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...
