Untapped Plant Microbiome Could Help Feed Billions

The Human Microbiome Project revealed tens of trillions of microbes residing in and on humans. Now scientists are taking a census of plant microbes—and not just the hundreds of billions found in soils. Distinct microbial communities live inside roots, on leaves and within flowers, and all in all... Read More

Vials of E. coli found in Ark. apartment

Vials of E. coli bacteria found in the refrigerator of a Jonesboro apartment have been safely removed, authorities said.

A maintenance man cleaning out the unit at the Willow Creek Apartments on Friday found 25 vials marked "E. coli" in a foam box in a refrigerator, officials said. The mainte... Read More

Plants prepackage beneficial microbes in their seeds

Plants have a symbiotic relationship with certain bacteria. These 'commensal' bacteria help the plants extract nutrients and defend against invaders -- an important step in preventing pathogens from contaminating fruits and vegetables. Now, scientists have discovered that plants may package thei... Read More

D- Zone Test for phenotypic detection of Inducible clindamycin Resistance

A positive D test indicates that the presence of macrolide-inducible resistance to clindamycin produced by an inducible methylase enzyme that alters the common ribosomal binding site for macrolides, clindamycin and the group B streptogrammins (quinupristin). This cross-resistance, called the ML... Read More

UEA researchers discover Achilles’ heel in antibiotic-resistant bacteria

Scientists at the University of East Anglia have made a breakthrough in the race to solve antibiotic resistance.

New research published today in the journal Nature reveals an Achilles’ heel in the defensive barrier which surrounds drug-resistant bacterial cells.

The findings pave the way f... Read More

Gelatin Hydrolysis

Pseudomonas aeruginosa, Escherichia coli and Serratia marcescens were inoculated into gelatin agar using the stab method and incubated for 1 week at 37 degree’s C. If the organism has gelatinase then it can break down the gelatin (protein) into polypeptides and then amino acids which can then ... Read More

Scientists Call for Investigation of Mysterious Cloud-like Collections in Cells

About 50 years ago, electron microscopy revealed the presence of tiny blob-like structures that form inside cells, move around and disappear. But scientists still don’t know what they do — even though these shifting cloud-like collections of proteins are believed to be crucial to the life of a c... Read More

Drugs fail to reawaken dormant HIV infection

Scientists report that compounds they hoped would "wake up" dormant reservoirs of HIV inside immune system T cells -- a strategy designed to reverse latency and make the cells vulnerable to destruction -- have failed to do so in laboratory tests of such white blood cells taken directly from pati...

Deadly Human Pathogen Cryptococcus Fully Sequenced

DURHAM, NC - Within each strand of DNA lies the blueprint for building an organism, along with the keys to its evolution and survival. These genetic instructions can give valuable insight into why pathogens like Cryptococcus neoformans -- a fungus responsible for a million cases of pneumonia and... Read More

Second American infected with Ebola

A second American aid worker in Liberia has tested positive for Ebola, according to the Christian humanitarian group she works for.

Nancy Writebol is employed by Serving in Mission, or SIM, in Liberia and was helping the joint SIM/Samaritan's Purse team that is treating Ebola patients in Monr... Read More

Printable Biotechnology

Cells, biological circuits, and individual biomolecules organize themselves and interact with the environment. Use of these capabilities in flexible and economically efficient biotechnological production systems is in the focus of the "Molecular Interaction Engineering" (MIE) project. It is the ... Read More

A recent study of biofilm formation in an archaeon revealed a fascinating form of social motility

A study of biofilm formation in the model haloarchaeal species Haloferax volcanii has led to the observation of a fascinating example of coordinated social motility (and of cellular differentiation and gene transfer). Haloferax volcanii was first isolated from Dead Sea sediment in 1975, but was ... Read More

Antibiotics may help Salmonella spread in infected animals, scientists learn

Some people infected with pathogens spread their germs to others while remaining symptom-free themselves. Now, investigators at the Stanford University School of Medicine believe they may know why.

When the scientists gave oral antibiotics to mice infected with Salmonella typhimurium, a bacte... Read More

Why a bacterium got its curve — and why biologists should know

Drawing from his engineering background, Princeton University researcher Alexandre Persat had a notion as to why the bacteria Caulobacter crescentus are curved — a hunch that now could lead to a new way of studying the evolution of bacteria, according to research published in the journal Nature ...

Amphibian communities collapse in wake of viral outbreak

Two closely related viruses that have been introduced to northern Spain in recent years have already led to the collapse of three different species of amphibian -- the common midwife toad, the common toad, and the alpine newt -- in the protected area of Picos de Europa National Park. In all, six... Read More

Sauerkraut: bacteria making food

Last week my husband needed some jars for cooking purposes. Tesco sell jars for somewhere around £3 each. However they also sell large jars full of sauerkraut for £1 each. Which means that last weekend we had an awful lot of sauerkraut to try and get through.

I’m not a great fan of sauerkraut... Read More

A Glass of Milk After Eating Sugary Cereals May Prevent Cavities

Washing down sugary breakfast cereal with milk after eating reduces plaque acid levels and may prevent damage to tooth enamel that leads to cavities, according to new research at the University of Illinois at Chicago College of Dentistry. Read More
