Abstract
Hytrosaviridae is a family of large, rod-shaped, enveloped entomopathogenic viruses with dsDNA genomes of 120-190 kbp. Hytrosaviruses (also known as salivary gland hypertrophy viruses) primarily replicate in the salivary glands of adult dipteran flies. Hytrosaviruses infecting the haematophagous tsetse fly and the filth-feeding housefly are assigned to two genera, Glossinavirus and Muscavirus, respectively. Whereas muscavirus infections are only overt, glossinavirus infections can be either covert or overt. Overt infections are characterized by diagnostic salivary gland hypertrophy and cause either partial or complete infertility. This is a summary of the International Committee on Taxonomy of Viruses (ICTV) Report on the family Hytrosaviridae, which is available at ictv.global/report/hytrosaviridae.
