This photomicrograph depicted a number of Gram-positive, endospore-forming Bacillus anthracis bacteria. B. anthracis is the pathologic microorganism responsible for the disease “anthrax”, an acute infectious disease, which most commonly occurs in wild and domestic vertebrates (cattle, sheep, goa...

On a dark-blue background, this illustration provides a 3D graphical representation of a generic influenza virion’s ultrastructure, and is not specific to a seasonal, avian or 2009 H1N1 virus. A portion of the virion’s outer protein coat has been cut away, which reveals the virus’ contents, and ... Read More

This 1975 transmission electron micrograph (TEM) revealed the presence of a number of infectious bronchitis virus (IBV) virions, which are Coronaviridae family members, and members of the genus Coronavirus. IBV is a highly contagious pathogen, which infects poultry of all ages, affecting a numbe... Read More

The New Scientist has published a nifty gallery of "psychedelic"-like images of human viruses. Many of them are from Government agencies so they are public domain. Click "source" to view the entire collection.
This negative stained transmission electron micrograph (TEM) shows recreated 1918 influenza virions that were collected from supernatants of 1918-infected Madin-Darby Canine Kidney (MDCK) cells cultures 18 hours after infection.
To separate these virions, the MDCK cells are spun down (centrif... Read More
