Laryngotracheitis Virus in Chickens
Infectious laryngotracheitis can be produced in chickens as an experimental model of severe nonfatal rhinitis and sinusitis. Inoculated intranasally into unanesthetized baby chicks it remains limited to the nasal fossa, produces acute desquamation of all nasal epithelia, results in functional recovery of the respiratory epithelium, but leaves important residual abnormalities. From the earliest ...
متن کاملHistopathology of Infectious Laryngotracheitis in Chickens
1. The characteristic lesions of infectious laryngotracheitis are ordinarily restricted to the respiratory tract and are most pronounced in the larynx and trachea. Sometimes the eyelids are affected. A certain percentage of the cases are associated with bronchitis and peribronchitis, pneumonic areas and hemorrhages in the lung, while the involvement of the nasal passages, communicating sinuses,...
متن کاملThe role of mucosal antibody in immunity to infectious laryngotracheitis virus in chickens.
The role of mucosal antibody in recovery from a primary infection and resistance to reinfection with infectious laryngotracheitis (ILT) herpesvirus was studied in bursectomized chickens, which were unable to synthesize specific antibodies. Viral antigen in the infected trachea was assessed by indirect immunofluorescence on tissue sections and by ELISA. The ability of bursectomized chickens to r...
متن کاملDetection of infectious laryngotracheitis virus (Gallid herpesvirus-1) from clinically infected chickens in Egypt by different diagnostic methods
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...
متن کاملMethylome Analysis in Chickens Immunized with Infectious Laryngotracheitis Vaccine
In this study we investigated the methylome of chickens immunized with Infectious laryngotracheitis (ILT) vaccine derived from chicken embryos. Methyl-CpG binding domain protein-enriched genome sequencing (MBD-Seq) method was employed in the detection of the 1,155 differentially methylated regions (DMRs) across the entire genome. After validation, we ascertained the genomic DMRs distribution an...
