infectious hypodermal and hematopoietic necrosis virus meaning
A subfamily of DNA arthropod viruses,in the family PARVOVIRIDAE. The host range includes members of Dictyoptera,DIPTERA,LEPIDOPTERA,Odonata,and ORTHOPTERA. There are three genera: DENSOVIRUS,Iteravirus,and Brevidensovirus. Densovirus-like viruses also infect and multiply in crabs and shrimp.
- Infection with WSSV differs from other described penaeid infections Yellowhead virus ( YHV ) and Infectious Hypodermal and Hematopoietic Necrosis virus ( IHHNV ) in the described histological findings as YHV has a reduced tissue specificity, infecting only the intestinal epithelial tissues and IHHNV causes intranuclear occlusions that stain eosinophillic but do not change over the course of the infection.
