The efficiency of hepatitis C virus (HCV) transmission by sexual activity remains controversial. We conducted a cross-sectional study of HCV-positive subjects and their partners to estimate the risk for HCV infection among monogamous heterosexual couples. A total of 500 anti–HCV-positive, human ... Read More

Researchers from the University of Toronto and SickKids Research Institute announced today that they have successfully mapped the genes in the fungus that causes Dutch Elm Disease. The researchers believe this is the first time the 30 million DNA letters for the fungus Ophiostoma ulmi have be... Read More
Without microbiology there would be no viral videos, because, after all, without microbiology there would be no viruses! Sure, there could be "voluminous views videos" but a term like that doesn't have the same visceral impact as a "viral video".

Hi Drs. Despommier and Racaniello,
This week you wondered why the immune-activating receptor for Toxoplasma gondii, TLR11, is present in mice but not in humans. You noted that it looks like there's no selective pressure keeping it around in us an... Read More
Viruses are obligate intracellular parasites, which means that they must enter a cell to reproduce. As virions are too large to diffuse passively across the plasma membrane, cellular pathways for uptake of extracellular materials provide entry routes. The first step in entry is adherence of viru...
