Prebiotics may be new weapon in the fight against childhood obesity

There may soon be a new tool in the fight against childhood obesity. Prebiotics reduce body fat in children who are overweight or obese by altering their gut microbiota, according to new research published in Gastroenterology, the official journal of the American Gastroenterological Association.

Greater gut bacteria diversity linked to longer progression-free survival in metastatic melanoma patients

The blend of bacteria in the digestive tract of metastatic melanoma patients is associated with disease progression or delay in patients treated with immunotherapy, researchers at The University of Texas MD Anderson Cancer Center report at the 2017 annual meeting of the American Society of Clinical Oncology.

Study finds increasing susceptibility of Staphylococcus aureus in U.S. hospital patients

Findings from a study that looked at susceptibility trends of Staphylococcus aureus in U.S. hospital patients showed that key antibiotics used to treat the bacteria became more active over the course of the study, a rare occurrence.

UTI treatment with antibiotics for older adults may be more harmful than previously thought

In a new research paper published in the Journal of the American Geriatrics Society, Thomas E. Finucane, MD, of the Johns Hopkins Geriatrics Center at Johns Hopkins in Baltimore, suggests that prescribing antibiotics for urinary tract infections (or "UTIs") may often be avoided among older adults.

Bacterial cell factories produce enzymes that can be used as active ingredients in drugs

Researchers at the Novo Nordisk Foundation Center for Biosustainability in Denmark have developed a method of producing P450 enzymes - used by plants to defend against predators and microbes - in bacterial cell factories. The process could facilitate the production of large quantities of the enzymes, which are also involved in the biosynthesis of active ingredients of cancer drugs.

Microbiologist explores new methods for analyzing fecal pollution in water

In a project supported by the Austrian Science Fund FWF, the microbiologist Andreas Farnleitner is looking at new methods for analyzing faecal pollution in water. Using DNA analytics, the scientist aims to develop comprehensive and simple methods to determine the extent and origin of faecal pollution.

UCSB biologists develop new antimicrobial susceptibility test to transform the way antibiotics are tested

When a patient is prescribed the wrong antibiotic to treat a bacterial infection, it's not necessarily the physician who is at fault. The current antibiotic assay -- standardized in 1961 by the World Health Organization and used worldwide -- is potentially flawed.

Study reveals key role of gut microbiota in treatment with classic diabetes medication

A clearer picture of how the classic diabetes medication metformin works has emerged. A recent study at Sahlgrenska Academy and University of Girona indicates that the clinical effect - control of blood glucose - is achieved through modulation of the gut microbiota.

MGH scientists show how Shigella survives journey from mouth to the colon

Surviving the treacherous journey through the human body from the mouth to the colon takes a special kind of bacterial pathogen.

TB germs' metabolic 'escape pathways' may be neutralized by new drugs to shorten duration of therapy

New research suggests the bacteria that cause tuberculosis alter their metabolism to combat exposure to antimicrobials, and that these metabolic "escape pathways" might be neutralized by new drugs to shorten the troublesome duration of therapy.

CRISPR may not be as foolproof as earlier believed – gene editing tech leads to unwanted mutations

CRISPR-Cas9 is a revolutionary new gene-editing technology that has been called “molecular scissors” and has been one of the handiest tools for genetic engineers in the recent times. It makes cutting and pasting gene sequences almost as easy as it sounds. CRISPR has been hailed as a breakthrough in genetic engineering.

Amped up antibiotic to fight resistant bacteria finally a reality

Resistant bacteria have been a menace killing thousands worldwide. Bacteria causing pneumonia, tuberculosis, wound and skin infections, gonorrhea have notably undergone major changes to evade the current armament of antibiotics that physicians have to fight them with.

New study finds dramatic reorganization of the gut caused by weight loss surgery

Obesity, already a global epidemic, is on the rise. Over one-third of the U.S. population is currently afflicted, according to the Centers for Disease Control and the monetary costs alone are approaching $150 billion dollars annually.

Yearlong study creates detailed map of microbial colonization in a newly opened hospital

A 12-month study mapping bacterial diversity within a hospital - with a focus on the flow of microbes between patients, staff and surfaces - should help hospitals worldwide better understand how to encourage beneficial microbial interactions and decrease potentially harmful contact.

Frequent recreational cannabis use linked to increased risk of gum disease

Columbia University dental researchers have found that frequent recreational use of cannabis--including marijuana, hashish, and hash oil--increases the risk of gum disease.

Drug market problems lead to shortage of essential antibiotics for treating sick children

Antibiotics used to treat a variety of common bacterial infections are becoming more difficult to access, mostly because the drugs are less profitable for manufacturers to produce and market, say experts.
