Cross-section through the center of a three-dimensional (3D) reconstruction of P22 phage, which is a virus that infects Salmonella bacteria. P22 contains many copies each of nine different viral proteins and a single copy of a double-stranded DNA genome (shown in green). The centrally located po... 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
I comment a bit, as an educator, about the loss of Carl Woese. Not only the importance of his discoveries, but how he went about his work, remains of great value. Read More
Culturing microbes on nutrient plate and testing for different kind of microbes on specific environment areas. This inoculated nutrient plate that was left for a period of 14 days showed the present of a few different kind of fungus species. It’s common to think that the human palm contains more... Read More
One of the most famous pictures of the Vaadhoo Island comes from a night where dots of light seemed to float to the shore. They made the cost look like it was covered in stars.
At night, it is not uncommon for Bio-luminescent microbes called Phytoplankton to be seen along the coast, though even... Read More
A spore from the bacterium Bacillus subtilis shows four outer layers that protect the cell from harsh environmental conditions.
Bacillus subtilis is a ubiquitous bacterium commonly recovered from water, soil, air, and decomposing plant residue. The bacterium produces an endospore that allows... Read More

Coxsackie viruses. Coloured transmission electron micrograph (TEM) of a group of Coxsackie viruses. These viruses were named after the town in the USA where they were isolated. They are entero- viruses, part of the Picornaviridae group. This group contains small, non-enveloped, icosahedral- shap... Read More

Echinococcus granulosus is a tapeworm parasite that in its larval form can cause hydatid disease, which is characterized by cysts forming within the victim's body. In order to complete its lifecycle, the tapeworm must infect two hosts, a carnivore and a herbivore.
The adult form of Echinococc... Read More

This transmission electron micrograph (TEM) revealed the ultrastructural appearance of a number of virus particles, or “virions”, of a hantavirus known as the Sin Nombre virus (SNV).
In November 1993, the specific hantavirus that caused the Four Corners outbreak was isolated. Using tissue fro... Read More
Listeria monocytogenes has a particular tropism for the central nervous system. To gain knowledge about the immune response elicited by L. monocytogenes in the brain, we used a rat ex-vivo organotypic nervous system culture as a model for Listeria infection. Brain sections were maintained severa... Read More
Physarum polycephalum, slime mold, grown in a large perti plate on moist paper towels using oatmeal as the food source. Culture was grown in the dark at room temperature. The paper towel was moistened every day with tap water. After 3 week’s the culture formed sporangia (fruiting bodies). Image ... Read More
