Genetic variability of the Avian leukosis virus subgroup J gp85 gene in layer flocks in Lower Egypt.

ABSTRACT:

Aim

This study aimed to determine the prevalence of layer flock tumor disease in Lower Egypt during the period of 2018-2019 and to undertake molecular characterization and determine the genetic diversity of all identified viruses.

Materials and methods

Forty samples were collected from layer chicken located in six governorates of Lower Egypt during the period of 2018-2019. Samples were taken from tumors in different organs. Tumor tissues were identified by histopathological sectioning and then further confirmed by a reverse-transcription polymerase chain reaction. Finally, genetic evolution of Avian leukosis virus (ALV-J) gp85 gene was studied.

Results

All the study samples were negative for Marek's disease virus, reticuloendotheliosis virus, ALV (A,B,C
