Acute Laryngotracheitis can be defined as subacute viral illness characterized by low grade fever, barking cough, inspiratory stridor and expiratory rhonchi. It is also known as infectious croup. Croup is an old Scottish word for sore throat with harsh breathing. It is seen in children between 3 month to 3 years of age (mean age 18 months)(l). Boys are more frequently affected. It occures more ...

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 ...

UNLABELLED Infectious laryngotracheitis (ILT) is a highly contagious acute respiratory disease of chickens caused by infectious laryngotracheitis virus (ILTV). The disease is controlled mainly through biosecurity and vaccination with live attenuated strains of ILTV and vectored vaccines based on turkey herpesvirus (HVT) and fowlpox virus (FPV). The current live attenuated vaccines (chicken embr...

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.

A boy with subglottic narrowing secondary to laryngotracheitis presented with noisy breathing. Acoustic measurements of tracheal sounds at standardized air flows correlated well with the clinical course and with spirometric assessments. This indicates the potential value of respiratory sound characterization in patients with upper airway obstruction.

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...
