Bacterial infection takes hold in the body when a pathogenic microorganism delivers toxins to healthy cells. One way bacteria accomplish this is by releasing vesicles, which act as tiny envelopes transporting toxins and other virulence factors to host cells. These toxins allow the bacteria to "m...

A urine specimen was collected by catheterized patient and sent to our Mycology laboratory for fungi research.
Small and translucid colony have grown on Sabouraud Agar (50mg chloramphenicol) culture after a week.
Microscopic analysis was performed and unusually shaped, swollen and large organ... Read More
Zika's hypothesized attraction to human neural stem cells may come from its ability to hijack a protein found on the surface of these cells, using it as an entryway to infection. In Cell Stem Cell on March 30, researchers at the University of California, San Francisco show that the AXL surface r... Read More
In this blog post, I describe how I had students create their own cartoon depicting microbiological ideas and concepts that most tickled their fancy. I did this on their final exam, and the students came up with really interesting and entertaining ideas. IT's always interesting to see what stu... Read More
Individuals with a psychiatric disorder involving recurrent bouts of extreme, impulsive anger--road rage, for example--are more than twice as likely to have been exposed to a common parasite than healthy individuals with no psychiatric diagnosis. Read More
Engineers have developed a rapid, low-cost genetic test for Zika. The $2 device, about the size of a soda can, doesn’t require electricity or technical expertise and only needs a bit of saliva. Read More
Researchers at University of California, San Diego School of Medicine have discovered that HIV infection of human immune cells triggers a massive increase in methylation, a chemical modification, to both human and viral RNA, aiding replication of the virus. The study, published February 22, 2016... Read More
With over half the U.S. population infected, most people are familiar with the pesky cold sore outbreaks caused by the herpes virus. The virus outsmarts the immune system by interfering with the process that normally allows immune cells to recognize and destroy foreign invaders. How exactly the ... Read More
Antibiotics have proven to be a valuable weapon in the fight against infectious bacteria. However, due to the excess use of antibiotics in conventional treatments, overtime antibiotics have become less effective. Read More
This holiday deer is a beautiful Christmas gift from our microbiology department. It was drawn with live bacteria: S. marcescens, S. aureus and S. epidermidis. Read More
A three-dimensional 'map' of a critical protein that malaria parasites use to invade human red blood cells could lead to a vaccine countering the most widespread species of the parasite. Read More
Some kids & I have been swabbing their classroom, and this colony caught my eye, or is it two colonies living in a mutualistic relationship. Perhaps this is commensalism as the red one seems to really like the yellow one. Or perhaps it is the same colony of microbes, somehow producing two differ... Read More
Organism: Micrococcus luteus, media: blood agar, colony: golden color
Micrococcus luteus is a Gram-positive, to Gram-variable, nonmotile, Coccus, saprotrophic bacterium that belongs to the family Micrococcaceae. M. luteus can produce a special pigment that is capable of absorbing wavelengths fr... Read More
Unknown fungal contaminant seen on Mueller Hinton agar after several months at refrigerated temperature. Colony had a white non-spore forming apron around the edges with green spore formation seen on the inner layer/center. Read More
Viruses have proven to be wily foes. Attempts to fend off viruses that cause the common cold or flu have failed, and new viral outbreaks such as dengue, Ebola, or Zika continue to elude drugs.
Given these challenges, scientists are tackling the problem from a different angle. The want to boos... Read More
DURHAM, N.C. -- Researchers at Duke Health are fine-tuning a test that can determine whether a respiratory illness is caused by infection from a virus or bacteria so that antibiotics can be more precisely prescribed. Read More
Every year one of every 10 people worldwide—mostly children and the poor—suffer from some kind of foodborne disease. Read More
New research demonstrates how climate change and the immune reaction of the infected individual can affect the long-term and seasonal dynamics of parasite infections. The study, led by Penn State University scientists, assessed the infection dynamics of two species of soil-transmitted parasites ... Read More
New research with a hydrogel and an antioxidant aims to make condoms both better and something people will actually want to use. Read More
