Blastocystis Parasite Blog

Our bodies are made up by cells containing our own DNA. Plus 10 times as many with foreign DNA. The bacteria found on our skin, and inside our organs (intestine, vagina, mouth, nose, etc.) are referred to as our “microbiome”, outnumber our own cells by 10 to 1, and make up a vital organ with ind...

Suzanne writes (re Aphids):


The best way to get rid of aphids in the garden (the ants in my yard love to herd them onto my okra) is a sharp stream of water from the hose. Aphids wash right off! They don't tend to come back right away, either.

Receptor for new coronavirus-EMC identified

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...

Pandoravirus, bigger and unlike anything seen before

The discovery of the giant Mimivirus and Megavirus amazed virologists (and also many others). Their virions (750 nanometers) and DNA genomes (1,259,000 base pairs) were the biggest ever discovered, shattering the notions that viruses could not be seen with a light microscope, and that viral geno...
