Many protozoan parasites (Trichomonas, Leishmania, Giardia, Plasmodium, Entamoeba, Nagleria, Eimeria, Cryptosporidium) are infected with viruses. These viruses do not infect vertebrates, but their double-stranded RNA genomes are sensed by the innate immune system, leading to inflammatory complications of protozoan infections. Trichomonas vaginalis is a protozoan parasite that infects the genitourinary ...

On episode #206 of the science show This Week in Virology, Vincent, Alan, Dickson, and Kathy discuss how the innate immune response to viral infection influences the production of pluripotent stem cells, and the diverse mobilome of giant viruses. You can find TWiV #206 at www.microbe.tv/twiv.

The Koala retrovirus (KoRV) continues to spread within Australia, according to results of a new analysis of a larger sample size from a wider geographical range than was previously studied. Blood or tissue samples were collected from koalas in different regions of Australia, and polymerase chain reaction (PCR) was used ...
