Infectious laryngotracheitis virus (ILTV) causes acute upper respiratory tract disease in chickens. Attenuated live ILTV vaccines are often used to help control disease, but these vaccines have well documented limitations, including retention of residual virulence, incomplete protection, transmission of vaccine virus to unvaccinated birds and reversion to high levels of virulence following bird...
Infectious Laryngotracheitis (ILT) is an acute highly contagious respiratory disease of chickens. It has significant economic importance due to mortalities and the decrease in egg production. In this study, twenty nine samples from different layer farms were collected outbreaks that occurred waset province, Iraq, at period November 2021 till March 2022 detect ILTV by molecular test through real...
(1) The technique of chorioallantoic membrane inoculation has been applied to the study of the virus of infectious laryngotracheitis as it occurs amongst Australian poultry. (2) When suitably diluted suspensions of virus are inoculated, isolated foci or pocks appear whose macroscopic form and histological structure is characteristic. The numbers of these foci may be used as a measure of the amo...
Infectious laryngotracheitis (ILT) is an acute and highly contagious respiratory disease of chickens caused by an alphaherpesvirus, infectious laryngotracheitis virus (ILTV). Recently, full genome sequences of wild-type and vaccine strains have been determined worldwide, but none was from Europe. The aim of this study was to determine and analyse the complete genome sequences of five ILTV strai...
Infectious laryngotracheitis (ILT) disease is an acute highly contagious viral disease leading to massive economic losses to the national poultry industry. This study aimed to identify the most accurate and rapid diagnostic methods to rescue layer poultry farms from intense outbreaks in Egypt. Fifty pathological specimens were collected and subjected to virus isolation (VI), histopathology, dir...
