BACKGROUND Newcastle disease virus represents APMV-1 and is the most characterized among all APMV types. The F protein cleavage site sequence is a well-characterized determinant of NDV pathogenicity in chickens. In this study, the sequences of fusion protein (F) gene of three Newcastle disease virus (NDV) strains isolated from outbreak in chickens in the(More)

Introduction protein (M), phosphoprotein (P), and nucleoprotein (NP), in the order 3'-NP-P-M-F-HN-L-5', [4,5]. NDVs Newcastle disease is a highly contagious and fatal were classified into three major pathotypes based on(More)
Rabbit hemorrhagic disease is an acute fatal highly contagious viral infectious disease that causes high losses among rabbitries. The disease was first reported in China in 1984 and later on in Saudi Arabia in 1996. The aim of this study was to investigate the emergence and pathogenicity of new rabbit hemorrhagic disease virus (RHDV) strains in Saudi(More)
AIM The aim of this study was to demonstrate the genomic features of Meq gene of Marek's disease virus (MDV) recently circulating in Saudi Arabia (SA). MATERIALS AND METHODS Two poultry flocks suffering from mortalities and visceral tumors were presented to the Veterinary Teaching Hospital, King Faisal University, SA. Subjected to different diagnostic(More)
