High-tech approach to combat sepsis

When Jason Martin gives a talk about his research, he begins with the dramatic story of Mariana Bridi da Costa: The young Brazilian supermodel died from severe sepsis in January after amputation of both her hands and feet failed to stop its spread.

Rhinosinusitis may be a factor in toxic shock syndrome in children

Rhinosinusitis (infection and inflammation in the sinus passages surrounding the nose) appears to be a primary factor in about one-fifth of toxic shock syndrome cases in children, according to a report in the June issue of Archives of Otolaryngology-Head & Neck Surgery.

Discovery shows potential for new severe asthma treatment

Scientists from King's College London and Imperial College London believe they have discovered a key element in the development of chronic asthma. Their research has been published in a new paper in the journal Proceedings of the National Academy of Sciences to explain why the structure and function of asthmatic airways are changed or ''remodelled'' and how this contributes to chronic asthma.

Dangerous liaisons: bacterial 'sex' causes antibiotic resistance

Some disease-causing bacteria are becoming resistant to antibiotics because they have peculiar sex lives, say researchers publishing new results today in the journal Science.

Bioprocess increases vaccine yield

Empa researchers have managed to adapt a process for manufacturing certain vaccines - in particular that against Haemophilus influenzæ bacteria - for use in bioreactors, with the result that the yield is enhanced enormously.

New insights into causes of multiple sclerosis

Over 100,000 people suffer from multiple sclerosis in Germany alone. Despite intensive research, the factors that trigger the disease and influence its progress remain unclear.

Cocaine and heroin increase permeability of the placenta

Cocaine and heroin increase permeability of the placenta. Researchers writing in BioMed Central's open access journal Reproductive Biology and Endocrinology have shown that exposure to the drugs causes an increase in the passage of some chemicals into the fetus.

GlaxoSmithKline opens pneumonia vaccine plant In Singapore

Drug maker GlaxoSmithKline (GSK) on Tuesday opened a $600 million plant in Singapore that is slated to begin producing vaccines to fight pneumonia-causing bacteria in 2011, Reuters reports.

New understanding of structure of bacteria responsible for traveler's diarrhea

Researchers at Boston University School of Medicine (BUSM), the Naval Medical Research Center and the National Institutes of Health, have solved the structure of thin hair-like fibers called "pili" or "fimbriae" on the surface of bacteria that cause traveler's diarrhea.

New discovery about mycobacteria – implications for tuberculosis research

A close relative of the microorganism that causes tuberculosis in humans has been found to form spores. This is a sensational finding because researchers have long been convinced that these kinds of bacteria - the mycobacteria - were incapable of forming spores.

New antibiotics could come from a DNA binding compound that kills bacteria in 2 minutes

A synthetic DNA binding compound has proved surprisingly effective at binding to the DNA of bacteria and killing all the bacteria it touched within two minutes.

Discovery 'significant step' in understanding leukaemia drug resistance

Scientists have pinpointed an enzyme responsible for breaking down and inactivating a key childhood leukaemia drug, which could help to explain why around 20 per cent of patients do not respond to therapy. Their findings are published in the Journal of Clinical Investigation.

Drug-resistant tuberculosis a very real threat in the Pacific region

Health officials in the Pacific are concerned about two new strains of tuberculosis - multi drug-resistant tuberculosis (MDR-TB) and extensively drug-resistant tuberculosis (XDR-TB) - both strains have been found to be resistant to the two most powerful drugs that have been used to treat tuberculosis (TB) for the past five decades.

Experimental drug five times more effective against MDR-TB than conventional therapy

A Johnson & Johnson-run study found that its experimental drug TMC207 could make conventional tuberculosis treatment five times more effective against multi-drug resistant TB (MDR-TB) because it cleared traces of the TB bacteria in the sputum of 48 percent of study volunteers after eight weeks, Reuters reports (Emery, Reuters, 6/3). The results were published on Wednesday in the New England Journal of Medicine.

One in four nursing home residents carries Methicillin-resistant Staphylococcus aureus

Methicillin-resistant Staphylococcus aureus (MRSA) is a major problem in nursing homes with one in four residents carrying the bacteria, a study by Queen's University Belfast and Antrim Area Hospital has found.

Discovery of two proteins may lead to more effective treatment of endocarditis and infections associated with implants

A research team at the Faculty of Odontology at Malmö University in Sweden has discovered two new proteins that are of importance to the survival of bacteria and their colonization of the human body. Besides enhancing our knowledge of the ability of bacteria to spread, the findings may also lead to more effective treatment of endocarditis and infections associated with implants.

Discovery of new genetic immune disorder in children

Your immune system plays an important function in your health - it protects you against viruses, bacteria, and other toxins that can cause disease. In autoinflammatory diseases, however, the immune system goes awry, causing unprovoked and dangerous inflammation.

Promising antimicrobial agent kills viruses, stimulates immune system

A promising antimicrobial agent already known to kill bacteria can also kill viruses and stimulate the innate immune system, according to researchers at National Jewish Health.

Soap-sniffing sensors that monitor health-care workers' hand hygiene by detecting sanitizer or soap fumes

Call it a breathalyzer for the hands. Using sensors capable of detecting drugs in breath, new technology developed at University of Florida monitors health-care workers' hand hygiene by detecting sanitizer or soap fumes given off from their hands.

Researchers examine 'invading' bacteria in DNA - advanced warfare on the most elemental of levels

Researchers at Texas A&M University's Artie McFerrin Department of Chemical Engineering have discovered how certain types of bacteria integrate the DNA that they have captured from invading enemies into their own genetic makeup to increase their chances of survival.
