The bacteria that cause cholera grab genes from other organisms in a particularly predatory and precise way, new research finds: They spear neighboring cells with a kind of poison-tipped spike.
Bacteria often grab genes from other organisms and incorporate that DNA into their own genomes. But... Read More
Chinese researchers have discovered what they say is the first ‘virological penicillin’ – MIR2911, a molecule found naturally in a Chinese herb called honeysuckle.
Honeysuckle (Lonicera japonica) is a well-known Chinese herb. In Traditional Chinese Medicine, it has been used to effectively tr... Read More
The multidrug-resistant, incredibly contagious Shigella has popped up in 32 US states in the past year. The bacteria infect your intestines and trigger crampy rectal pain, bloody or mucus-laced diarrhea and vomiting. What can you do? Vigilant hygiene. And if you do get sick, go for an over-the-c...

Delftia acidovorans (formerly Comamonas acidovorans) is an aerobic gram-negative rod. It is unique because produces an orange color in the medium with the addition of Kovac's indole because of the production of anthranilic acid from typtone, though the organism is biochemically indole-negative. ...

Unknown fungal isolated contaminant found on MAC. MAC plate was incubated for 2 months at 4 degrees C once fungal growth was seen. This colony seemed to emerge from the agar and had a 3D appearance. The center of the colony had what seemed to be hyphal growth while the edges had a hard waxy un... Read More
PROVIDENCE, R.I. [Brown University] -- A new study provides evidence from lab experiments that a drug already used in people to fight tapeworms might also prove effective against strains of the superbug MRSA, which kills thousands of people a year in the United States. Read More
Many different microbes can cause pneumonia, and treatment may be delayed or off target if doctors cannot tell which bug is the culprit. A novel approach—analyzing a patient's breath for key chemical compounds made by the infecting microbe—may help detect invasive aspergillosis, a fungal infecti... Read More
Let's face it: colonoscopies are pretty unpleasant. But what if you could eat a spoonful of yogurt to check for cancer rather than enduring that procedure? MIT professor Sangeeta Bhatia is working on engineered bacteria that detects colorectal cancer. Read More
Rivers and streams could be a major source of antibiotic resistance in the environment.
The discovery comes following a study on the Thames river by scientists at the University of Warwick’s School of Life Sciences and the University of Exeter Medical School.
The study found that greater n... Read More

New results from a safety and immunogenicity study, which included a challenge phase to test efficacy, indicate that a live attenuated enterotoxigenic Escherichia coli (ETEC) vaccine candidate, given in combination with a novel adjuvant, provided significant protection against disease. This repr... Read More
It may come as a bit of a surprise to learn that bacteria have an immune system - in their case to fight off invasive viruses called phages. And like any immune system - from single-celled to human - the first challenge of the bacterial immune system is to detect the difference between "foreign"... Read More
This picture was taken in early October 2014 in the Washington, DC metro area. The temperature that week had been in the mid-70's during the day to the low 60's at night (Fahrenheit), and it hadn't been too humid. This had grown at the base of a tree, and was very large -- my hand is in there fo... Read More
Methylobacterium aquaticum strain NO00 (KR920749) grown over rice grain. It can produce phytohormones and other beneficial metabolites for the plant. M. aquaticum is a plant growth promoting (PGP) bacteria". Its pink-biofilm, can help with water-stress and protect the plant against pathogens. Read More
Bacteria are as individual as people, according to new research by Professor Peter Young and his team in the Department of Biology at the University of York. Bacteria are essential to health, agriculture and the environment, and new research tools are starting to shed more light on them.

Engineered E. coli can store long-term memories of chemical exposure, other events in their DNA.
MIT engineers have transformed the genome of the bacterium E. coli into a long-term storage device for memory. They envision that this stable, erasable, and easy-to-retrieve memory will be well su... Read More
Rob Knight is a pioneer in studying human microbes, the community of tiny single-cell organisms living inside our bodies that have a huge — and largely unexplored — role in our health. “The three pounds of microbes that you carry around with you might be more important than every single gene you...
