The recent Ebola outbreak in West Africa has claimed more than 11,300 lives and starkly revealed the lack of effective options for treating or preventing the disease. Progress has been made on developing vaccines, but there is still a need for antiviral therapies to protect health care workers a... 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
Scientists have shown how a parasitic worm infection common in the developing world increases susceptibility to tuberculosis. The study demonstrated that treating the parasite reduces lung damage seen in mice that also are infected with tuberculosis, thereby eliminating the vulnerability to tube... 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
Unknown organism, possible Bacillus spp, seen on a hand print after hand washing. TSA plate was grown at 37 C for 24 hours then left at refrigerated temps for 4 weeks. Organism was a light brown and mat. The center of the growth was smooth with rhizoid like growth on the edges which were mucoid... Read More
Washington, DC – November 18, 2015 – Coconut oil may be effective at combating infection with Candida albicans, according to a study published November 18th in the American Society for Microbiology’s new open access journal mSphere. The study found that coconut oil consumption reduced gastrointe... Read More

A study on the potential of SARS-virus-like bat coronaviruses to cause human disease has reawakened the debate on the risks and benefits of engineering viruses. Let’s go over the science and then see if any of the criticisms have merit. Read More
Although there has been some movement toward more judicious use of antibiotics, there are still people who take the drugs thinking it will help the common cold, and dentists who regularly prescribe antibiotics for patients prior to some common oral surgeries like third molar extraction.
These... Read More
Bacterial resistance to antimicrobial agents is a significant problem for both human and veterinary medicine, but little research has been done on the prevalence or mechanisms of resistance in horses and other companion animals, and how such resistance might impact human health. Read More
I would like to see a Twitter hash tag for microbiologically themed Jack-o-Lanterns for Hallowe'en!
In my Microbiology course here at the University of Puget Sound, my student Ruth created this bacteriophage inspired pumpkin art.
#HappyMicrobialHalloween, everyone! Read More
A new study reveals that many European hospitals fail to routinely test people who may be at risk of an HIV-infection. If tests were more widely offered in the healthcare system, fewer HIV-patients would go unnoticed, especially in Northern Europe. Read More
Recent research published in the Journal of Bacteriology is focused exactly on this question: how do bacteria transfer antibiotic resistance genes? In the current article, Drs. Dominic Poulin-Laprade and Vincent Burrus examine the mechanism of gene transfer in Vibrio cholerae, the bacterium that... Read More
Unknown organism, possible yeast or Bacillus, seen on a hand print after hand washing. TSA plate was grown at 37 C for 24 hours then left at refrigerated temps for 4 weeks. Organism was light yellow and mucoid . There are numerous rings of growth (looks like layers of rope) with lobate margins.... Read More
I enjoy mixing Hallowe'en with my classes. In this blog post, I show how my microbiology students do exactly that, with humor and style. In addition, my freshman writing students do the same with their course on symbioses and parasitism. Enjoy...and #HappyMicrobialHalloween! Read More
Unknown organism, possible yeast, seen on a hand print after hand washing. TSA plate was grown at 37 C for 24 hours then left at refrigerated temps for 4 weeks. Organism was light yellow, mat in the center and mucoid towards the outside. There are several rings of growth with each ring havin... Read More
The Nature of Death explores the possibilities of life being created through death. With the growth of similar looking bacteria in my samples, I am able to exhibit that life grows post-mortem and allows beautiful nature to coalesce around it. Having taken samples of gravestones of a U.S. World W... Read More
Extracellular vesicles are membrane-bound structures that are released away from cells into the environment. These vesicles carry signaling molecules, nutrient scavenging molecules, immune-modulating molecules – the list goes on and on. Every cell type examined produces vesicles, too: bacterial,... Read More
