Secrets to the Danish success in combating antimicrobial resistance

The global consumption of antimicrobial agents for animals is almost twice the size of human consumption. Since the mid-1990s, Denmark has reduced animal consumption of antimicrobial agents by 60% without reducing its agricultural output. In a comment in the journal Nature, Professor Frank Møller Aarestrup, the National Food Institute, Technical University of Denmark, gives his explanation of the success of the Danish efforts.

Big challenges from antibiotic resistant bacteria

Antibiotic resistant bacteria are increasing and spreading at an alarming speed. The bacterial evolution is overwhelming our antibiotic defense. More and more bacteria are becoming resistant to antibiotics resulting in fatal consequences for millions of people. We need common action and responsibility for the development of new effective antibiotics and to stop antibiotic misuse.

UMass Amherst biochemist receives NIH grant to map molecular structure of bacterial needle

Biochemist Alejandro Heuck at the University of Massachusetts Amherst recently received a five-year, $950,000 grant from the National Institutes of Health to map the molecular structure of a needle-like tool used by deadly bacteria to drill holes in mammalian cell walls.

Inhibiting immune response during initial multi-drug therapy could speed TB treatment time

Inhibiting a key immune response in mice during initial multi-drug treatment for tuberculosis could - paradoxically - shorten treatment time for the highly contagious lung infection according to new research from Johns Hopkins Children's Center and the Center for TB Research.

RapidChek- SELECT Salmonella highly sensitive to the presence of S. Typhi vaccine in stool

Salmonella Typhi (S. Typhi) is the causative agent of typhoid fever, a serious health threat resulting in some 22 million new cases yearly and approximately 217,000 fatalities. A number of novel vaccine candidates using live attenuated strains of Salmonella are being developed, but care must be taken to ensure the bacteria are not excreted into the environment following vaccination.

Flu immunity depends on number of viruses involved during initial infection

Not only does the type of flu virus affect a patient's outcome, but a new research report appearing in the Journal of Leukocyte Biology suggests that the number of viruses involved in the initial infection may be important too.

Oral health may be linked to HPV status of head and neck cancer

The chronic oral inflammatory disease periodontitis may be associated with human papillomavirus status in individuals with head and neck squamous cell carcinoma, report researchers.

TB research finds body’s own response helps TB bacteria survive

Inhibiting a key immune response in mice during initial multi-drug treatment for tuberculosis could — paradoxically — shorten treatment time for the highly contagious lung infection according to new research from Johns Hopkins Children’s Center and the Center for TB Research. Shorter duration of drug therapy is key, researchers say, to increase treatment compliance for the growing global health threat posed by the disease.

Dietary fiber can improve gastrointestinal health

A University of Illinois study shows that dietary fiber promotes a shift in the gut toward different types of beneficial bacteria. And the microbes that live in the gut, scientists now believe, can support a healthy gastrointestinal tract as well as affect our susceptibility to conditions as varied as type 2 diabetes, obesity, inflammatory bowel disease, colon cancer, and autoimmune disorders such as rheumatoid arthritis.

Nanosphere receives FDA marketing approval for Verigene GP Blood Culture Nucleic Acid Test

The U.S. Food and Drug Administration today allowed marketing of the first nucleic acid test that can identify 12 different bacterial types known to cause bloodstream infections.

New type of micromachine can penetrate tissue and overcome cellular barriers

Microscopically small submarines that can swim through our blood to clear out clogged arteries or destroy malignant tumors. This concept may sound utopian, but it isn’t. Various micro- and nanomachines have in fact already been developed.

Scientists identify novel mechanism behind bacterial pathogenesis

Scientists have identified a new mechanism of bacterial pathogenesis. The results of the research project, partly funded by the Academy of Finland, have been published in the journal Proceedings of the National Academy of Sciences of the United States of America (PNAS).

Link between bacterial vaginosis and female-to-male HIV transmission risk

An investigation led by UCSF has found that the risk of female-to-male HIV transmission is increased three fold for women with bacterial vaginosis, a common disorder in which the normal balance of bacteria in the vagina is disrupted.

Biological filter to remove estrogens from waste water and drinking water

A biological filter to remove estrogens from waste water and drinking water. The 15 Bielefeld students submitting this project to the 'international Genetically Engineered Machine competition' (iGEM) at the Massachusetts Institute of Technology (MIT) in Boston, USA are setting their sights high.

Survey of home healthcare practices related to infection control

A healthy boy was infected with antibiotic-resistant bacterium that was traced to his mother's nurse's bag left in the family's car after his mother's home healthcare visit to a patient with the same infection. Although the boy's infection and the patient's infection were never DNA tested, the coincidence was remarkable.

Researchers create endothelial cells with blood-brain barrier qualities

The blood-brain barrier -- the filter that governs what can and cannot come into contact with the mammalian brain -- is a marvel of nature. It effectively separates circulating blood from the fluid that bathes the brain, and it keeps out bacteria, viruses and other agents that could damage it.

Benefits of green banana flour-based pasta for people with celiac disease

People with celiac disease struggle with limited food choices, as their condition makes them unable to tolerate gluten, found in wheat and other grains. Researchers from the University of Brazil have developed a gluten-free pasta product from green banana flour, which tasters found more acceptable than regular whole wheat pasta.

Surprising link between dietary fat and cholesterol absorption

Buttery shrimp. Fried eggs. Burgers and fries. New research suggests there may be a biological reason why fatty and cholesterol-rich foods are so appealing together.

Scientists identify novel animal reservoir for tick-borne diseases

A team of scientists at Washington University in St. Louis has been keeping a wary eye on emerging tick-borne diseases in Missouri for the past dozen years, and they have just nailed down another part of the story.

First study to demonstrate that microbes are specific to their host species

Gut bacteria's key role in immunity is tuned to the host species, researchers have found, suggesting that the superabundant microbes lining our digestive tract evolved with us-a tantalizing clue in the mysterious recent spike in human autoimmune disorders.
