• On the basis of strong epidemiologic evidence, influenza and parainfluenza viruses are responsible for significant morbidity and mortality in young infants and children and in persons with chronic medical conditions. (1)(4)(26)(27)(35). • On the basis of research evidence, influenza vaccines are effective in preventing disease in high-risk individuals. (8)(17)(18). • On the basis of strong re...
A 3698 bp region of the genome of infectious laryngotracheitis virus (ILTV) was sequenced and found to contain the entire glycoprotein gB gene and the C-terminal region of a gene homologous to the ICP 18.5 protein gene of herpes simplex virus type 1. The ILTV gB gene encoded a protein with an Mr of 100K possessing all the characteristics of a transmembrane glycoprotein. Alignment of the ILTV gB...
Endosomal toll-like receptor-21 and -9 sense CpG DNA activating production of pro-inflammatory mediators with antimicrobial effects. Here, we investigated the induction of antiviral response of in ovo delivered CpG DNA against infectious laryngotracheitis virus (ILTV) infection. We found that in ovo delivered CpG DNA significantly reduces ILTV infection pre-hatch correlating with the expression...
Infectious Laryngotrachitis (ILT) is an acute respiratory disease with high morbidity and low mortality in poultry. ILT is caused by Gallid herpesvirus 1 (GaHV-1), a member of the Iltovirus genus and family Herpesviridae. It resulted in notable economic losses due to decreasing the growth rates, egg production, and increasing the mortality in commercial poultry, especially layer flocks, and usu...
Infectious laryngotracheitis virus (ILTV; Gallid herpesvirus 1) is an alphaherpesvirus that causes acute respiratory disease in chickens. The role of glycoprotein G (gG) in vitro has been investigated in a number of alphaherpesviruses, but the relevance of gG in vivo in the pathogenicity of ILTV or in other alphaherpesviruses is unknown. In this study, gG-deficient mutants of ILTV were generate...
Recombination between herpesviruses has been seen in vitro and in vivo under experimental conditions. This has raised safety concerns about using attenuated herpesvirus vaccines in human and veterinary medicine and adds to other known concerns associated with their use, including reversion to virulence and disease arising from recurrent reactivation of lifelong chronic infection. We used high-t...
