This negatively-stained transmission electron micrograph (TEM) revealed the presence of Rubella virus virions, as they were in the process of budding from the host cell surface to be freed into the host’s system, thereby, producing an enveloped virus particle, which means that after budding, the...

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

This microscopy image provided by Dr. Carl June, shows immune system T-cells, center, binding to beads which cause the cells to divide. The beads, depicted in yellow, are later removed, leaving pure T-cells which are then ready for infusion to the cancer patients. Scientists are reporting the fi... Read More

This is an image of Clostridium difficile colonies grown on cycloserine mannitol agar after 48 hours.
C. difficile, an anaerobic gram-positive rod, is the most frequently identified cause of Antibiotic-Associated Diarrhea (AAC). It accounts for approximately 15-25% of all episodes of AAC.
