PMRV joins XMRV as possible etiologic agent of ME/CFS

From Virlogy Blog:

PMRV joins XMRV as possible etiologic agent of chronic fatigue syndrome

And this may help people understand why XMRV and PMRV are almost identical.



In a nutshell? Xenotropic (XMRV or Xenotropic Murine Leukemia Virus Related Virus) means the MLV infects humans but not mice. Polytropic (PMRV, or Polytropic Murine Leukemia Virus Related Virus) means it can infect both. Or better reported by Mindy at CFS Central: "Polytropic viruses infect the original host—in this case mice—as well as other species, whereas xenotropic viruses like XMRV infect species other than the original host."

No worries. Very soon, they will assign a better gammaretrovirus name.
