Study provides insight into why individual mycobacteria respond differently to antibiotics

Tuberculosis is one of the most common infectious diseases in the world, infecting almost 10 million people each year. Treating the disease can be challenging and requires a combination of multiple antibiotics delivered over several months.

Studies shed more light on relation between bacteria, immune system and antibiotics

Antibiotics and the immune system are the two forces that cope with bacterial infections. Now, two studies from Isabel Gordo's laboratory, at Instituto Gulbenkian de Ciência, show for the first time that resistance to antibiotics and to the immune system is interconnected in bacteria.

New test strip can rapidly, cost-effectively detect disease pathogens

At present, bacteria, fungi or viruses can generally only be detected with certainty by way of elaborate laboratory tests or animal experiments. The food and pharmaceutical industries would like to have faster tests to check their products.

Inhalable ibuprofen holds potential to treat cystic fibrosis

Ibuprofen: You can buy it at any drug store, and it will help with that stabbing headache or sprained ankle. One of the ways it does so is by reducing inflammation, and it is this property that may also help patients with cystic fibrosis.

New supplement could help reduce urge to consume high-calorie foods

Eating a type of powdered food supplement, based on a molecule produced by bacteria in the gut, reduces cravings for high-calorie foods such as chocolate, cake and pizza, a new study suggests.

AHR plays role in modulating the body's innate immune response to viral infections

A receptor, first known for its role in mediating the harmful effects of the environmental pollutant dioxin in our body, is now understood to play other important roles in modulating the innate immune response.

Wolbachia bacterium can prevent mosquitoes from transmitting Zika virus

Researchers at the University of Wisconsin-Madison have confirmed that a benign bacterium called Wolbachia pipientis can completely block transmission of Zika virus in Aedes aegypti, the mosquito species responsible for passing the virus to humans.

Resistant starch in diet improves balance of gut bacteria, decreases cholesterol

The secret ingredient is in the flour, but its impact lies within the gut. Adding resistant starch to the diets of people with metabolic syndrome can improve bacteria in the gut, according to research from South Dakota State University.

New research identifies flaws in LM-method for Lyme disease

A new microscopy technique (LM-method) developed to detect Lyme disease is unable to distinguish infected patients from healthy controls, yielding false-positive results that could lead doctors to over-diagnose a patient, according to new research published in the journal Infectious Diseases.

Study links alpha-defensin genes to IgA nephropathy risk

A gene which forms part of our body's first line of defence against infection may be associated with an increased risk with a type of kidney disease, research involving academics at The University of Nottingham has discovered.

Researchers find main cause of necrotizing enterocolitis-related lung damage in preemies

Johns Hopkins researchers report they have figured out a root cause of the lung damage that occurs in up to 10 percent of premature infants who develop necrotizing enterocolitis, a disorder that damages and kills the lining of the intestine.

Allergy-causing immune cells play life-saving role in deadly C. difficile infection

Researchers at the University of Virginia School of Medicine have identified immune cells vital for protecting us from potentially fatal C. difficile infection. Surprisingly, those cells are often vilified for their role in causing asthma and allergies. But when it comes to C. difficile, they could be the difference in life and death.

Experts receive NIH grant to study why some HIV-infected individuals resist TB

Case Western Reserve University School of Medicine experts and colleagues in the United States and Africa have received an $11 million, five-year NIH grant to understand why some people living with HIV in Africa avoid becoming infected with the bacterium that causes tuberculosis (TB) despite exposure to high-TB-risk circumstances.
