- Abstract
Simple Summary: Marek's disease (MD) is caused by herpesvirus and is a common disease of chickens, usually characterized by tumors in various tissues. Lately, numerous studies have also shown an increasing incidence of the disease in turkeys. This report describes various clinical signs and pathological changes in three different flocks of commercial turkeys in Slovenia. Molecular analysis confirmed the presence of identical Marek's disease virus (MDV) strains in all three cases and showed that the MDV detected is most similar to the MDV detected in chickens in Tunisia. Marek's disease (MD), caused by Mardivirus gallidalpha 2 (GaAHV-2), also known as MD virus (MDV), is a lymphoproliferative disease that primarily affects chickens. Recently, MDV has been detected in lymphomatous tumors in turkeys in various countries. Between 2021 and 2023, three cases ranging from no to severe clinical disorders (depression, lameness, and increased mortality) occurred in commercial turkey flocks in Slovenia. In all cases, MDV was detected by PCR in DNA samples extracted from organs developing tumor infiltrations. Sequencing and phylogenetic analysis of the meq gene revealed that the GaAHV-2 detected has molecular features of a very virulent pathotype and genetic similarity with GaAHV-2 detected in chickens in Tunisia. This is the first report of MDV in commercial turkeys in Slovenia.
