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

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

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

From The Program of 1st Annual Meeting Society of American Bacteriologists, 1899

Wouldn’t you be tempted to attend such a session if it were part of a current-day ASM meeting? The first five papers ever delivered to a meeting of the Society of American Bacteriologist (now the ASM) are so utterly relevant to our concerns that they could be delivered now. No changes to the ti... Read More

Rhizopus microsporus

Rhizopus microsporus
It causes human mucormycosis and bovine mycotic abortion.
It is distinguished from R.arrhizus by its shorter stalk, and smaller sporangia and spores.
Variant forms
Var.oligosporus : has elongated columellae ; spores less obviously striated.
Var.rhizopodiformis : has ... Read More

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

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

Physar polycephalum

This is a slime mold by the name of Physarum polycephalum. Part of him crept out of the petri dish that had been mistakenly written on with a blue wet erase marker. During growth, I wrap these plates up in foil because the slime mold needs complete darkness to grow. The foil and the humidity ... Read More
