Molecular 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 کاملControl of thymidine kinase synthesis in IHD vaccinia virus-infected thymidine kinase-deficient LM cells.
The synthesis of vaccinia virus-induced thymidine kinase is normally arrested several hours after infection. In thymidine kinase-deficient LM cells infected with IHD strain of vaccinia virus, arrest occurs whether or not viral DNA synthesis is inhibited. With virus inactivated by UV irradiation, enzyme synthesis takes place, but arrest is abolished. It is suggested that an early viral genetic f...
متن کاملPlaque autoradiography assay for the detection and quantitation of thymidine kinase-deficient and thymidine kinase-altered mutants of herpes simplex virus in clinical isolates.
A plaque autoradiography assay to detect and quantitate thymidine kinase (TK) mutants of herpes simplex virus type 1 (HSV-1) and HSV-2 in clinical samples is described. This method utilizes the selective incorporation of [125I]iododeoxycytidine, a pyrimidine analog selectively phosphorylated by the HSV TK. Only cells infected with TK-competent virus will efficiently incorporate iododeoxycytidin...
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 کاملAnalysis of the nucleotide sequence of DNA from the region of the thymidine kinase gene of infectious laryngotracheitis virus; potential evolutionary relationships between the herpesvirus subfamilies.
We have sequenced a 5.4 kb region of the genome from the avian herpesvirus infectious laryngotracheitis virus (ILTV) and identified genes homologous to the thymidine kinase (TK) gene, the capsid p40 gene of herpes simplex virus type 1 (HSV-1), a gene encoding a protein antigenic in Epstein-Barr virus infections plus one other highly conserved gene encoding a protein implicated in cell fusion in...
