Lipid Agar

Lipid Plate/Tributyrin Agar used to test for an organisms ability to produce the exoenzyme lipase which breaks down the lipids in the agar creating a clear zone around the organism. (A) Serratia marcesens, lipid hydrolysis, indicated by a zone of clearing around the growing colony, as well as th... Read More

Starch Agar

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

These Renderings of HIV Show That a Deadly Virus Can Be Beautiful

For those of us who are normal, non-scientist people, an image of a virus doesn't necessarily hold any meaning. Which floating orb is a healthy cell? And which one is the actual virus? The CGSociety recently invited artists to create renderings of the HIV virus in blood—and the winning images ar... Read More

Vincent van Gogh's "The Starry Night" #agarart2015

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

Molecular 'kiss of death' flags pathogens

DURHAM, N.C. -- Many bugs that make us sick -- bacteria, viruses, fungi and parasites -- hide out in our cells in protective little bubbles called vacuoles. To clear an infection, the immune system must recognize and destroy these vacuoles while leaving the rest of the living cell intact. Read More

Strategies to decrease bacterial colonization

Among the bacterial infections that are most difficult to treat, chronic infections associated with bacterial biofilms are one of the most hazardous. Bacterial biofilms are densely packed communities of microbial cells surrounded with secreted polymers. In her doctoral thesis, chemist Shoghik Ha... Read More

3 ANTIBIOTICS GANG UP TO KILL DEADLY STAPH

As a trio, three antibiotics that aren’t individually effective against a drug-resistant staph infection killed the deadly pathogen in test tubes and mice. Read More

VIRUSES FROM NEWBORN GUT ARE NEW TO SCIENCE

Shortly after a baby’s birth, bacteria aren’t the only invaders to colonize the gut. Viruses move in, too, according to new research. Read More

Role of breast cell infection in flu transmission between mothers and breast-feeding ferrets

Influenza is known as an infectious respiratory disease, but a study published on October 8th in PLOS Pathogens suggests that infected cells in breast tissues could play a role in virus transmission from mothers to breast-feeding infants and vice versa using a ferret model. Read More

You'll Want To Wash Your Hands Immediately After Reading This (Infographic)

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

Aquaspirillum serpens

A simple stain done on a stock culture of Aquaspirillum serpens to look at cell shape. This culture was grown in TSB at room temperature, ~21 degrees C, for several months. Aquaspirillum is a slow grower normally found in pond water. A characteristic spiral rod can be seen in the center of ... Read More

Some vaccines support evolution of more-virulent viruses

Scientific experiments with the herpesvirus such as the one that causes Marek's disease in poultry have confirmed, for the first time, the highly controversial theory that some vaccines could allow more-virulent versions of a virus to survive, putting unvaccinated individuals at greater risk of ...

Shoe Swab

Unknown organism isolated from a swab taken off the bottom of a shoe. Students were asked to swab something in the classroom. One swab was done on the bottom of a shoe and incubated on a TSA plate for 48 hrs at 37 degree’s C. The organism was difficult to scrape so a small chunk of the organis... Read More

Cartography of the Human Body

Artist Sonja Bäumel explores the skin microbiome in her project Cartography of the Human Body. Bacteria isolated from Bäumel’s skin were characterized and grown individually, then used to reconstruct an artificial microbiome with many layers of differently-colored species. Giant petri dishes gre... Read More

Bioluminescent art: Beautiful bacteria glow in the dark

HIV cure research: NIH scientists create 2-headed protein to deplete HIV reservoir

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
