However, staph bacteria can also cause serious and sometimes fatal infections, such as bloodstream infections, surgical woun...

Bacteria use host's immune response to their competitive advantage

...llions of bacteria live within the recesses of our noses and upper respiratory tracts, waiting for a chance to infiltrate and infect. But long before these bacteria break through our immune defenses, they must first compete against other bacterial species to colonize the mucus-lined surfaces of our noses. ...

Doctors should stop prescribing antibiotics for the common cold, review advises

...ven days or less or with colds that included runny noses with colored discharge for 10 days or less. The patients had been given either antibiotics or placebo.

Nose odors and mouth odors: The brain distinguishes

...ir experiments, they inserted small tubes into the noses of volunteers such that one tube ended at the nostrils and the other ended farther back in the nasal passage near the throat, where odors from the mouth would originate. As they introduced odors into one tube or the other, they scanned the subject's ...

Reducing antibiotic use lowers rates of drug-resistant bacteria

...lled pneumococci, are commonly found in children's noses and throats, and can result in ear infections, sinusitis, pneumonia and even meningitis. Many pneumococcal infections are treated with penicillin, but resistance to the drug is making the microbes more difficult to control. Researchers in France te...

Pillows - a hot bed of fungal spores

...scovered millions of fungal spores right under our noses - in our pillows. Aspergillus fumigatus, the species most commonly found in the pillows, is most likely to cause disease; and the resulting condition Aspergillosis has become the leading infectious cause of death in leukaemia and bone marrow tra...

Smell of success for nanobiosensors

... IST programme, will ultimately lead to electronic noses based on natural olfactory receptors that could be...d nanobiosensors to mimic the way human and animal noses respond to different odours. This new nose biosensor is unusual in how it's made. By placing a lay...

MRSA vaccine shows promise in mouse study

...s "Staph," is common, found on the skin and in the noses of an estimated 30 percent of people worldwide. It is a frequent source of skin infections, which can usually be treated without antibiotics, but it can also cause serious surgical wound infections, bloodstream and bone infections, or pneumonia. The...

New technology to speed up research into Huntington's disease

...ce learnt to touch the correct stimulus with their noses and were able to learn the correct stimulus to obtain a reward by day 10. The researchers also demonstrated that when the stimuli were reversed (so the stimulus that had previously been correct was now incorrect), HD mice struggled with the task a...

Breathing easy: When it comes to oxygen, a bug's life is full of it

... They are not, because they do not breathe through noses or mouths. Instead, insects draw in oxygen through holes in their bodies known as spiracles and pump the oxygen through a system of increasingly tiny tubes (tracheae) that deliver oxygen directly to tissues and muscles. Insects typically have a pair ...

Baby fish 'smell their way home'

...ween about 9 and 14mm long, already have developed noses ?but the question was whether they could use them to recognise what the home reef smelt like, when they left it only a day or so after hatching." The team exposed tiny fish larvae in a tank to pure streams of water from four different reefs. To t...

New research shows sharks use their noses and bodies to locate smells

...y marine biologists, sharks can not use just their noses to locate prey; they also need their skin – specifically a location called the lateral line. The lateral line is an organ used by all fish to detect, with exquisite sensitivity, movement and vibration in the surrounding water. According to the resear...
