When you're hard drive fails, you order a new one online and then swap it out. Why can't we do that for biological parts as well? From DNA robots and "organs-on-a-chip" to nanobristles that grab-and-release drugs, this slideshow explores the two major goals of synthetic biology: to build new bio... Read More
Unknown fungal isolated contaminant found on MAC. MAC plate was incubated for 2 months at 4 degrees C once fungal growth was seen. This colony seemed to emerge from the agar and had a 3D appearance. The center of the colony had what seemed to be hyphal growth while the edges had a hard waxy un... Read More
CORVALLIS, Ore. - The creation and sustainment of "safe spaces" may play a critical role in community-based HIV prevention efforts by providing social support and reducing environmental barriers for vulnerable populations, a new study from an Oregon State University researcher has found. Read More

Nitrate reduction test for the reduction of nitrate in nitrate media, to determine if the bacteria contains nitrate and/or nitrite reductase. Organism were incubated for 48 hr's at 37 degree's in nitrate media then reagents added.
Nitrate broths after the addition of 10 drops re... Read More
The immune system exercises constant vigilance to protect the body from external threats--including what we eat and drink. A careful balancing act plays out as digested food travels through the intestine. Immune cells must remain alert to protect against harmful pathogens like Salmonella, but th... Read More
This paper addresses some fundamental unanswered questions in microbiology: is the cytoskeletal cell division ring a major driving force for bacterial cytokinesis as it is for eukaryotes? If so, what is the mechanism? If not, what process is the major driving force?
One key technique that we ... Read More
Bacteriophages were named because it appeared that the bacteria were being eaten by something. Here is a healthy E. coli strain (MG1655) that was mixed with a suspension of P1 phages and poured onto an agar plate. As the lawn of cells grew and covered the whole surface, plaques can be seen where... Read More
Unknown organism, possible Bacillus spp, washed hand print done on a TSA plate. Organism was the size of a dime, muciod/ rhizoid in the center and mat/smooth at the outer edges. Read More
In this blog post, I show a science-cartoon by the great "Beatrice the Biologist" that illustrates an important point in my freshman introductory cell and molecular biology course: no matter how tired we might be, we are incredibly busy on a cellular level! Beatrice is a fine artist who underst... Read More
Contrary to current medical dogma, researchers at University of California, San Diego School of Medicine and Skaggs School of Pharmacy and Pharmaceutical Sciences report that the common antibiotic azithromycin kills many multidrug-resistant bacteria very effectively -- when tested under conditio...

This negatively-stained transmission electron micrograph (TEM) revealed ultrastructural morphology of the Middle East Respiratory Syndrome Coronavirus (MERS-CoV), which was formerly known as novel coronavirus.
(MERS-CoV) was identified in 2012 as the cause of respiratory illness in people. Inve... Read More
Unknown Fungal Contaminant found on TSA plate that had been refrigerated for 1 month. Colony was raised in the center with deep groves around the colony. Green spore formation was seen in the middle with white non-spore forming hyphae towards the edges. Read More

The Lyme disease spirochete, Borrelia burgdorferi, is an obligate parasite that cycles between ticks and vertebrate hosts. B. burgdorferi alters the proteins expressed on its outer surface, depending on the state of each host. Here, we used immunofluorescent antibodies to identify spirochetes th... Read More
