Microbes in the Environment

Microbes are everywhere; they live in us and on us. They can't be seen with our naked eyes, thus we tent to neglect that they're there or even existed. Some microbes are harmful and some are not. However, we must learn to avoid contaminating sterile media and materials with these microbes. In th... Read More

Fuzzy Frosty

This smiling Frosty is no ordinary snowman—he's made entirely of mold.

The living artwork is the creation of Stephanie Mounaud, an infectious disease researcher at the J. Craig Venter Institute (JCVI) in Rockville, Maryland.

For the last several Christmases, Mounaud has used the different ... Read More

Protein that delays cell division in bacteria may lead to idenfication of new antibiotics

Bacteria adjust to wide fluctuations in food supply by controlling how big they get and how often they divide. Scientists at Washington University in St. Louis have just worked out the control system E. coli use to delay division so they can bulk up when food suddently becomes abundant. What can... Read More

Lyme Disease Bacteria, Borrelia burgdorferi

The Lyme disease spirochete, Borrelia burgdorferi, is an obligate parasite that cycles between ticks and vertebrate hosts. B. burgdorferi alters the proteins expressed on its outer surface, depending on the state of each host. Here, we used immunofluorescent antibodies to identify spirochetes th... Read More

ASM GM 2014 - Where Pathogens Can Linger on Airplanes

Many air travelers are concerned about the risks of catching a disease from other passengers given the long time spent in crowded air cabins. New research shows disease-causing bacteria can linger on surfaces commonly found in airplane cabins for days, even up to a week. Participants discuss ... Read More

Blood agar/Hemolysis

Three organisms inoculated onto blood agar, straight line inoculation, to demonstrate hemolysis. From top to bottom:
Streptococcus pyogenes: beta, complete lysis of red blood cells, clear area around colony growth.
Streptococcus bovis: alpha, incomplete lysis of red blood cells, green area ... Read More

Exoenzyme activity

Ms. Karen Alarcon, 3rd yr - BS Biology student from St. Paul University Quezon City, Philippines is doing an exercise on exoenzyme screening by select bacterial isolates. On the picture, bacteria on starch agar flooded with iodine was analysed for the production of exoenzyme amylase. Read More

Nematode Host Meets Bacterial Pathogen

This image shows the nematode host Caenorhbaditis elegans encountering the bacterial pathogen S. marcescens. Natural selection imposed by the co-evolving pathogen led to the evolution and maintenance of bi-parental sex in the host population.

The host and the pathogen were experimentally co-e... Read More

Assortment in colony biofilms

Effect of founder cell density on the spatial pattern formation in colony biofilms.
The colony biofilms were obtained by following the protocol described in van Gestel et al (2014) ISME Journal (doi: 10.1038/ismej.2014.52). Briefly, GFP and mKATE2 labeled Bacillus subtilis strain were mixed in ... Read More

Microbe vs. Mineral - A Life and Death Struggle in the Desert

Although the bursts of rainbow colors in this photograph are mesmerizing, microbes fight for their lives in the background. Chemist Michael P. Zach of the University of Wisconsin-Stevens Point, snapped this image of a salt sample he collected in a hot, arid valley near Death Valley National Park... Read More
