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...
متن کاملInfectious rous sarcoma virus and reticuloendotheliosis virus DNAs.
An efficient and quantitative assay for infectious Rous sarcoma virus and reticuloendotheliosis virus DNAs is described. The specific infectivities of viral DNA corresponded to one infectious unit per 10(5) to 10(6) viral DNA molecules. Infection with viral DNA followed one-hit kinetics. The minimal size of infectious Rous sarcoma virus DNA was approximately 6 million daltons, whereas the minim...
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 کاملReticuloendotheliosis virus sequences within the genomes of field strains of fowlpox virus display variability.
Nine field strains of fowlpox virus (FPV) isolated during a 24-year span from geographically diverse outbreaks of fowlpox in the United States were screened for the presence of reticuloendotheliosis virus (REV) sequences in their genomes by PCR. Each isolate appeared to be heterogeneous in that either a nearly intact provirus or just a 248- or 508-nucleotide fusion of portions of the integrated...
