Macacine gammaherpesvirus 4 (McHV-4), commonly known as rhesus lymphocryptovirus (RLV), is a species of virus in the genus Lymphocryptovirus, subfamily Gammaherpesvirinae, family Herpesviridae, and order Herpesvirales.[1]
In nature, Macacine gammaherpesvirus 4 infects rhesus macaques (Macaca mulatta).
Comparison with Human gammaherpesvirus 4
[edit]Its genetic structure has been fully sequenced and found to be highly homologous with that of Human gammaherpesvirus 4, commonly known as Epstein-Barr virus, at 65%. The structural proteins are highly conserved, while genes expressed during Human gammaherpesvirus 4 latent infection are much less well conserved. Even in cases where genes have low homology, the Macacine gammaherpesvirus 4 infection genes are functionally interchangeable with Human gammaherpesvirus 4 genes.[2]
Macacine gammaherpesvirus 4 infection in rhesus monkeys resembles Human gammaherpesvirus 4 infection in humans in several respects:
- Oral transmission,
- Atypical lymphocytosis
- Lymphadenopathy
- Activation of CD23+ peripheral blood B cells
- Sustained serologic responses to lytic and latent Human gammaherpesvirus 4 antigens
- Latent infection in the peripheral blood
- Virus persistence in oropharyngeal secretions
These features make the rhesus lymphocryptovirus potentially useful for studying the pathogenesis, prevention, and treatment of Human gammaherpesvirus 4 infection and associated oncogenesis.[3]

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
