Certain viral infections are known to increase or decrease HIV-1 replication or viral load, perhaps by competing with the same receptors, or via immune and other effects.Many autoantibodies in HIV-1 infection also target the immune network and this may well contribute to pathology. Read More
Whether or not the retrovirus XMRV is a human pathogen has been debated since the virus was first described in 2006. The answer is now clear: the results of Blood XMRV Scientific Research Group, along with a partial retraction of the 2009 Science paper describing identification of the retrovirus... Read More
Life in a high-pressured environment with practically nothing to eat might be ok for high-fashion models, but it’s an unlikely lifestyle choice for a single cell whose usual overriding goal is to become two cells. Yet the largest living ecosystem on Earth—the deep biosphere—is comprised of micro... Read More
Merry Youle of Small Things Considered has authored a post that looks at Thiomargarita spp.
"Non-motile Thiomargarita was first discovered in 1999 off the Namibian coast, thus was named T. namibiensis. Its cells are large spheres, arranged in chains, each chain enclosed in a mucous sheath. Av... Read More
Today is World Tuberculosis Day.

The hunt continues for novel antiviral agents especially against the pandemic H1N1 virus. In this article, a drug that has been used to fight HIV infection and vesicular stomatitis now appears to have the potential to block influenzavirus infection by inhibiting neuraminidase. This may be yet ... Read More
