Bananas contain a substance that, when changed slightly by scientists, shows promise to fight a wide range of viruses, including the flu. Read More
Watch the pilot episode of BioFilms in which we explore some creepy microbes just in time for Halloween. Learn how algae can suffocate a pond of all its life, discover the vampire bacterium known as Vampirococcus who literally sucks the life out its victims, and watch out for those sweet Hall...

In this blog post (and fourth "Mu-Tube" video), I explore the idea that all animals and plants have evolved as part of a microbial world, and thus microbes are a part of us. I do this by having my undergraduate students explore two recently publications by Dr. Margaret McFall-Ngai,and recording... Read More
A common denizen of the undergraduate microbiology laboratory, Serratia marcescens is well known for the production of a bright red pigment, prodigiosin. Prodigiosin has been investigated over many years for its possible antimicrobial, antifungal, and even antitumor effects. Still, the relevan... Read More
Washington, DC – October 23, 2015 - A phage showed strong anti-microbial activity against a type of food-borne bacterium that often kills infants after infecting them via infant formula. Phages are viruses that infect only bacteria. The research is published October 23 online in Applied and Envi... Read More
Plague infections were common in humans 3,300 years earlier than the historical record suggests, reports a study published October 22 in Cell. By sequencing the DNA of tooth samples from Bronze Age individuals from Europe and Asia, the researchers discovered evidence of plague infections roughly... 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
Methicillin Resistant Staphylococcus aureus (MRSA) isolated from animals. The organism was grown on seven different agar medium. On blood agar (Centre), it forms small to medium sized colonies surrounded by weak beta-hemolysis. It shows diverse types of color in different chromogenic medium- pin... Read More
Scientists have identified a gene that could potentially open the door for the development of new treatments of the lethal disease sepsis. Read More
Scientists at the National Institutes of Health (NIH) have created a protein that awakens resting immune cells infected with HIV and facilitates their destruction in laboratory studies. The protein potentially could contribute to a cure for HIV infection by helping deplete the reservoir of long-... Read More
At the request of a friend, they wanted me to draw a "Petri fish". Hektoen agar, Salmonella typhimurium, E. coli.
Unknown organism seen on a hand print after washing with soap and water grown on a TSA plate for 24 hrs, room temperature for a day and several days at refrigerated temp. Organism was a pale yellow with raised rhizoid growth in the center some of it matt and some mucoid, edges were undulate. Read More
We took a few swabs around school - a few cultures have grown up that I am unable to identify. The first is this orange culture, which came from our water fountains (photo is 3 days after the sample was taken). Read More

A small grape leaf was pressed/printed onto a large TSA plate incubated for 48 hrs at 37 degree's C, then place at refirigerated temps for 3 days. The result was a mix of yeast (yellow/orange) , several Bacillus spp and a variety of other unknown organisms. The outline of the leaf is not that ... Read More
