Germaphobes, maybe you're on to something.
Sickness-causing bacteria and viruses can lurk on surfaces long after they're expelled in an infected person's sneeze or snot. Some can even stay on a surface for months, given the right conditions. While the ability of these microorganisms to actual... Read More
microbes in the environment: there are about 4 to 5 different colonies of bacteria which is growing in agar plate; sample from library toilet seat. (front view) Read More
Slime production by Staphylococcus epidermidis on Congo Red agar; demonstrated by black colored colonies. Slime production is one of the most important virulence factors produced by Coagulase negative Staphylococci.
The colonies of slime non-producing strains remain pink to red.
ANN ARBOR, Mich. -- Like a collection of ragtag villagers fighting off an invading army, the mix of bacteria that live in our guts may band together to keep dangerous infections from taking hold, new research suggests. Read More
Physarum polycephalum, slime mold, grown in a large perti plate on moist paper towels using oatmeal as the food source. Culture was grown in the dark at room temperature. The paper towel was moistened every day with tap water. After 3 week’s the culture formed sporangia (fruiting bodies). Im... Read More

While not original art, it’s still a fun piece. BBL’s CHROMagar Orientation agar is the canvas for this piece of agar art. Chromogens in the agar release a colored compound when hydrolyzed by specific enzymes allowing certain bacteria to appear different colors on it. The brown color is Proteus... Read More
The days when antibiotics worked reliably and scientists could assume they worked directly—like popping a balloon—are fading. As resistance mounts, understanding how antibiotics really work could be the key to sustaining their efficacy. Read More
Starch agar contains high molecular weight starch molecules (soluable starch). When Iodine is added it reacts with starch to produces a dark brown/purple color. A zone of clearing forms around organisms that produce the exoenzyme amylase after addition of iodine. This plate was incubated for ... Read More
Scientists are one step closer to understanding how a normally harmless fungus changes to become a deadly infectious agent. Read More
Phytoplankton may be microscopic, but that doesn’t mean we can’t see them. Just look up: These little critters are brightening up cloudy days around the world. Read More
Results of analysing air by Using Merck Millipore Mas 100 Eco Air Sampler. Here i used DRBC agar and i got some molds. It was 100 lt volume. there is no yeast but we can see clearly molds. Read More
BLOOMINGTON, Ind. -- Health experts have warned for years that the overuse of antibiotics is creating "superbugs" able to resist drugs treating infection. Read More
Prions are fascinating, enigmatic, and might teach us not only about rare prion diseases like Creutzfeld-Jakob disease, mad cow disease, or scrapie, but also about other more common neurodgenerative diseases. Two studies published on July 2nd in PLOS Pathogens report progress with novel tools an... Read More

In this third installment of my "Mu-Tube" video series about microbiology and microbiology education, I discuss how I was initially labeled a "microbial supremacist" as a joke, and then embraced the title with enthusiasm. I also show many examples of the microbiology-related art I use to encour... Read More

To better understand the importance of gut bacteria in human health, researchers measured the time it takes food to move through the gastrointestinal tract, called gut motility, in mice—in a way that mimics the dietary effects of world travel. Read More
