Multilocus analysis of Gallid herpesvirus 1 in layer chickens in Iraq.

ABSTRACT:

Background and aim

Infectious laryngotracheitis virus (ILTV) causes a highly pathogenic respiratory disease that affects poultry. It is also known as Gallid herpesvirus 1. ILT prophylaxis measures often include using live attenuated vaccines. The live attenuated vaccine can, however, lead to the formation of new strains of ILTV as a result of vaccine reversion and recombination with field strains. Therefore, this study was performed to explore the multilocus variation of ILTV strains of field and vaccine origin. Samples were tested from two distinctive geographical areas in Iraq as little is known about the ILTV genetic diversity within these areas.

Materials and methods

The polymerase chain reaction method was utilized to generate sequencing templates of six highly p
