Genus “Marek’s Disease-like Viruses”

Genus “Marek’s Disease-like Viruses”

Type Species

Gallid herpesvirus 2

(GaHV-2)

Distinguishing Features

Nucleotide sequences or predicted amino acid sequences of members of the genus form a distinct lineage within the subfamily. Members of the genus have been found only in birds and are the only members of the subfamily associated with malignancy. Production of infectious extracellular virus appears to be limited to feather-follicle epithelium. All current members cross-react serologically.
