We report here the first genome sequence of infectious laryngotracheitis virus isolated in Peru from tracheal tissues of layer chickens. The genome showed 99.98% identity to the J2 strain genome sequence. Single nucleotide polymorphisms were detected in five gene-coding sequences related to vaccine development, virus attachment, and viral immune evasion.

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...

The large amounts of feathers produced by the poultry industry, that is considered as a waste was explored for possible uses in various industries, such as meals for animals, biofuels, biodegradable plastic materials, combating water pollution and more. That review mentions these uses, but concentrate on the utilization of feathers for the diagnosis of viral infections and for monitoring vaccin...

For detection of infectious laryngotracheitis virus (ILTV) antibody, glycoprotein B-, C-, and D-based enzyme-linked immunosorbent assays (B-, C-, and D-ELISAs, respectively) were developed. The B- and D-ELISAs showed enhanced detection of anti-ILTV antibodies in infected chickens compared to that of the commercial ELISA. Furthermore, the D-ELISA was efficient in detecting seroconversion with ve...

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...

The aim of the study was to evaluate effectiveness PCR-RТ method using PCR-RТ-IS test system for etiological diagnosis whooping cough in examination patients with infectious respiratory pathology prolonged and contact persons. 113 children aged from 1 month 17 years, 11 months 29 days, 146 family members were examined. Regardless initial diagnosis, all examined by bacteriological, molecular gen...

DNA from infectious laryngotracheitis virus (ILTV) was randomly sheared and cloned into the M13 bacteriophage. Clones containing ILTV DNA were sequenced and the predicted amino acid sequences were compared to the known sequences of other herpesviruses using computer analysis. Twenty-one ILTV genes were identified, 20 by comparison to varicella-zoster virus and 19 by comparison to herpes simplex...
