As a closer view of PHIL 12265, this photograph depicts the colonial morphology displayed by Gram-negative Yersinia pestis bacteria, which was grown on a medium of sheep's blood agar (SBA), for a 72 hour time period, at room temperature. Y. pestis is the bacterium responsible for causing the inf... Read More

Living in the guts of worms are seemingly innocuous bacteria that contribute to their survival. With a flip of a switch, however, these same bacteria transform from harmless microbes into deadly insecticides.

In the current issue of Science, Michigan State University researchers led a study t... Read More

Bacterial genomes differ dramatically in size: from 140Kb to 13Mb (those numbers might be off now...please let me know if something has broken the record. Yes, I know the lower estimate can change based on semantics, but there are a bunch in that range). Although we have some clues as to how sel... Read More

Scientists' finding is a major breakthrough in understanding a decades-old problem of how bacteria detect environmental changes.

A team of scientists led by Assistant Professor Ganesh S Anand and Professor Linda J. Kenney from the National University of Singapore (NUS) Department of Biologica... Read More

In the first field study of its kind researchers at Royal Holloway, University of London and the University of Oxford have investigated the competitive dynamics of pathogenic and non-pathogenic strains of bacteria.

Bacteria are increasingly seen as living and interacting in groups and sharing... Read More

Scientists studying loss of bone and muscle mass among astronauts find that spaceflight’s effects on microscopic worms may help them live longer.

The researchers discovered that spaceflight suppresses accumulation of toxic proteins that normally accumulate within aging muscle.

In addition,... Read More

Insects have been around for almost 400 million years. That’s plenty of time for evolution to fashion countless horrific deaths for them. Case in point: some insects die because a little worm vomits glowing bacteria inside their bodies.

The worm is Heterorhabditis bacteriophora, a microscopic... Read More

Across the horizon and miles out to sea toward the north, the Atlantic Ocean's own spring and summer ritual is unfolding: the blooming of countless microscopic plant plankton, or phytoplankton.

In what's known as the North Atlantic Bloom, an immense number of phytoplankton burst into color, f... Read More

A new global study mapping human-animal diseases like tuberculosis (TB) and Rift Valley fever finds that an "unlucky" 13 zoonoses are responsible for 2.4 billion cases of human illness and 2.2 million deaths per year. The vast majority occur in low- and middle-income countries.

The report, wh... Read More

I’ll confess, I never quite thought about what happens when you get millions of a single kind of bacteria all together in one place and take a nice long sniff. I did not think it would ever be pleasant. I was wrong.

This level of olfactory whimsy, then, was totally new to me: Pseudomonas aeru... Read More

An investigation led by UCSF has found that the risk of female-to-male HIV transmission is increased three fold for women with bacterial vaginosis, a common disorder in which the normal balance of bacteria in the vagina is disrupted.

The new research assessed the association between bacterial... Read More

At one time or another, every human goes through the rather introverted and personal experience of omphaloskepsis.

The term, better known as navel-gazing, originally described the act of self-reflection through a complete physical and mental focus on the bellybutton. The practice has been rec... Read More

Happy Fourth of July! In honor of this historic holiday we’ve compiled a list showing how infectious diseases and vaccines have affected the lives of our most heralded leaders – the American presidents. These concise accounts are evidence that diseases can strike anyone, anywhere at any time, an... Read More

Bloodstream infections caused by the MRSA superbug may be on the decline in communities across the U.S., according to a large study of military personnel.

Previous data from the Centers for Disease Control and Prevention show a drop in infections contracted in healthcare settings. But the tra... Read More

Scientists at the University of Texas Health Science Center San Antonio are investigating a potential new drug that could improve learning and memory during aging -- thanks to Easter Island?

The drug, called rapamycin, comes from isolated bacterial products in the soil of the Polynesian islan... Read More

In the search for new life, scientists have studied the depths of the ocean and the lips of steaming volcanoes. They've looked on Mars and the moons of Jupiter, and even planets beyond this solar system.

A team of dentists and scientists from Newcastle University are developing a new product from a marine microbe to protect dentures, teeth and gums from bacteria in the mouth.

They are using an enzyme isolated from a marine bacterium Bacillus licheniformis found on the surface of seaweed which... Read More
