Gram-negative bacteria pose a particular challenge to any enterprising phage. First the phage is met by the outer membrane (OM)—a barrier to surmount that also can be used as a convenient handgrip for adsorption. Next hazard is the nuclease-infested periplasm with its jungle of peptidoglycan. An... Read More
The benefits and risks of "gain-of-function" research into highly pathogenic microbes with pandemic potential must be evaluated, scientists say. A group of over 50 researchers has called on the European Commission to hold a scientific briefing on research that involves engineering microbes to m... Read More
HPV self-testing is as effective as tests done by doctors, according to a Lund University study. Simple HPV home tests could therefore complement existing screening programmes, and identify more women at risk for cervical cancer.
Sweden has a system of regular gynaecological smear tests, whic... Read More
Microbiologists are trying to work out whether use of antibiotics on farms is fuelling the human epidemic of drug-resistant bacteria.
The sight of just one boot coming through the doorway cues the clatter of tiny hoofs as 500 piglets scramble away from Mike Male. “That's the sound of healthy ... Read More
A new approach to treating antibiotic-resistant infections has been developed by University of Wollongong (UOW) and University of New South Wales’ (UNSW) researchers who have patented the new technology and entered into commercialization discussions with two French pharmaceutical companies.

A fungus that decimates white pines has mutated and can now infect immune and resistant plants, say researchers.
This change is alarming to researchers, growers, loggers, and forest managers.
White pine blister rust (WPBR) infects white pines and Ribes, a plant genus that include gooseberr... Read More
A universal infant vaccination campaign in China has led the Hepatitis B virus (HBV) to more than double its rate of "breakout" mutations. These mutations may enable the virus to elude the vaccine, necessitating new vaccination strategies. Researchers at the Chinese Centers for Disease Control a... Read More
New research presented at the 4th American Society for Microbiology (ASM) Conference on Salmonella today demonstrates culture-independent identification and strain typing of multiple Salmonella serotypes directly from enriched food samples using PathoGenetix’s Genome Sequence Scanning (GSS) tech...

The coronavirus that’s killed 71 people was detected in three camels in Qatar, supporting a thesis that the animals may be a source of human infection.
The dromedary camels were identified in a barn about 19 miles northwest of Doha owned by a 61-year-old man who was diagnosed in October with ... Read More

Gut bugs can change the way our brains work, offering new ways to relieve problems like stress, anxiety and depression, say two leading professors
We acquire our intestinal microbes immediately after birth, and live in an important symbiotic relationship with them. There are far more bacteria... Read More
Michael Laub studies the complex interactions that underlie cells’ responses to their environment. Bacteria encounter a constant barrage of ever-changing temperature, acidity and chemical stimuli from their environment. The cells must absorb all of this information and choose the correct respons... Read More

The NDSU Department of Veterinary and Microbiological Sciences researchers discovered that B-phenylethylamine, or PEA, reduced the number of cells of Escherichia coli in a beef broth. PEA is a substance found in chocolate in trace amounts. Health food stores sell it in pill form to improve peopl... Read More
The lack of data on the effectiveness of medicines available to doctors and researchers is "of extreme concern" say a group of MPs.
The Public Accounts Committee is calling for all data on drugs being prescribed in the UK to be made available.
It also says the government spent £424m stockp... Read More
Working with a synthetic gene circuit designed to coax bacteria to grow in a predictable ring pattern, Duke University scientists have revealed an underappreciated contributor to natural pattern formation: time.
In a series of experiments published Oct. 8, 2013, in the journal Molecular Syste... Read More
There is much that should be remembered about those days of intensive exploratory work and much of it using very simple methods and instruments. There was a remarkable amount of sharing of current work and results without much concern for primacy, which was automatically recognized. Communicatio... Read More
A doctoral research project studying the bacterium Brucella pinnipedialis, which commonly occurs in hooded seals, found that this bacterium does not cause disease in hooded seals, as other Brucella bacteria do in other species.
The occurrence of the bacterium B. pinnipedialis in hooded seals ... Read More
Italian officials should not go ahead with expensive clinical tests of an unproven stem-cell therapy that has no good scientific basis.
The Italian government is planning to oversee a clinical trial of a controversial stem-cell therapy. There are many reasons for the trial to be stopped — and... Read More
Rather than destroying bacteria to fight infections, a University of Illinois at Chicago researcher is trying to "tweak" their savvy communication networks and block the signals that lead to infection and disease.
Researchers have known for several decades that bacteria communicate through a ... Read More
