Identification of 21 genes of infectious laryngotracheitis virus using random sequencing of genomic DNA.
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...
متن کاملMolecular biology of avian infectious laryngotracheitis virus.
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...
متن کاملDiscordant results from hepatitis C virus genotyping by procedures based on amplification of different genomic regions.
We compared the results of genotyping hepatitis C virus (HCV) either by PCR amplification of the core region or by hybridization of PCR-amplified products of the 5' untranslated region (5'UTR assay). Serum samples from 144 Italian anti-HCV-positive patients (106 drug abusers and 38 patients with chronic viral liver disease but no history of drug abuse) were studied. The original core region ass...
متن کاملAvian infectious laryngotracheitis.
Avian infectious laryngotracheitis (ILT) herpesvirus continues to cause sporadic cases of respiratory disease in chickens world-wide. Sources of transmission of ILT infection are three-fold, namely: chickens with acute upper respiratory tract disease, latently infected 'carrier' fowls which excrete infectious laryngotracheitis virus (ILTV) when stressed, and all fomites (inanimate articles as w...
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...
