At a magnification of 1125X, this photomicrograph revealed some of the ultrastructural morphology exhibited by a Histoplasma capsulatum fungal macroconidium. The reproductive spores produced by H. capsulatum can be either macroconidia or microconidia. It is the macroconidia that exhibits finger-... 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
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

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.
