Marek’s disease virus (MDV), an alphaherpesvirus of poultry, causes Marek’s disease and is characterized by visceral CD4+TCR??+ T-cell lymphomas in susceptible hosts. Immortal cell lines harbouring the viral genome have been generated from ex vivo cultures of MD tumours. As…

Transmission of viruses from the commercial poultry to wild birds is an emerging paradigm of livestock–wildlife interface. Here, we report the identification and isolation of vaccine strains of avian paramyxovirus serotype 1 (APMV1) and avian coronaviruses (ACoV) from…

PML nuclear bodies (PNBs) are proteinaceous structures which predominantly reside inside the nuclei of mammalian cells. Their antiviral effects on a wide range of DNA and RNA viruses are shown. Viruses have evolved a diverse range of mechanisms to overcome the antiviral…

The number and diversity of viral sequences that are identified in metagenomic data far exceeds that of experimentally characterized virus isolates. In a recent workshop, a panel of experts discussed the proposal that, with appropriate quality control, viruses that are known…

Influenza A virus infections are a global health threat to humans and are endemic in pigs, contributing to decreased weight gain and suboptimal reproductive performance. Pigs are also a source of new viruses of mixed swine, avian, and human origin, potentially capable of…

Bioluminescence is a powerful tool in the study of viral infection both in vivo and in vitro. Foot-and-mouth disease virus (FMDV) has a small RNA genome with a limited tolerance to foreign RNA entities. There has been no success in making a reporter FMDV expressing a…

Crimean-Congo haemorrhagic fever virus (CCHFV) is a zoonotic virus transmitted by Hyalomma ticks, the immature stages of which may be carried by migratory birds. In this study, a total of 12 Hyalomma ticks were recovered from five of 228 migratory birds trapped in Spring…

Marek's disease virus (MDV) is an alphaherpesvirus that induces T-cell lymphomas in chickens. Natural infections in vivo are caused by the inhalation of infected poultry house dust and it is presumed that MDV infection is initiated in the macrophages from where the infection…

H9N2 avian influenza viruses are enzootic in poultry across Asia and North Africa where they pose a threat to human health, both as zoonotic agents and as potential pandemic candidates. Poultry vaccination against H9N2 viruses has been employed in many regions, however…
