Flesh-eating bacteria claims life of Florida woman

A Florida woman died late last week from flesh-eating bacteria two weeks after cutting her leg while walking along the coast. Carolyn “Lynn” Fleming, 77, lived in Ellenton and visited Coquina Beach, near St. Petersburg, on June 14. While wading in the water, she stumbled and suffered a small cut her on her left shin,

Take two E. coli and call me in the morning: Synthetic bacterial memory circuits enable microbial diagnostics for sensing biomolecules in the gut

Millions of people take capsules of probiotics with the goal of improving their digestion, but what if those bacteria were also able to detect diseases in the gut and indicate when something is awry? New research from the Wyss Institute at Harvard University and Harvard Medical School (HMS) has created an effective, non-invasive way to

Widely available antibiotics could be used in the treatment of ‘superbug’ MRSA

Some MRSA infections could be tackled using widely-available antibiotics, suggests new research from an international collaboration led by scientists at the University of Cambridge and the Wellcome Sanger Institute. Since the discovery of penicillin, the introduction of antibiotics to treat infections has revolutionised medicine and healthcare, saving millions of lives. However, widespread use (and misuse)

Bacteria in our body determine health and disease

Role of microorganisms in the human underestimated so far There is a powerful and invisible Kingdom, which ruled largely undetected in the human body, about health and illness, decides. The speech is from the human Microbiome, i.e., the total number of microorganisms that colonize in a human. These billions of micro live support beings, and

Cranberry extract makes the bacteria more susceptible to antibiotics

Interaction between cranberry and bacteria discovered The large-fruited cranberry is better known under its English name of Cranberry. The relatives of the blueberry and cranberry contains plenty of vitamins and minerals. The berry is said to have a healing effect on urinary tract infections. The scientific evidence was lacking to date. Now a canadian research

Manuka honey to kill drug-resistant bacteria found in cystic fibrosis infections

Manuka honey could provide the key to a breakthrough treatment for cystic fibrosis patients following preliminary work by experts at Swansea University. Dr Rowena Jenkins and Dr Aled Roberts have found that using Manuka honey could offer an antibiotic alternative to treat antimicrobial resistant respiratory infections, particularly deadly bacteria found in Cystic Fibrosis (CF) infections.

Common food additive found to affect gut microbiota: Titanium dioxide nanoparticles E171 may impact human health

University of Sydney research provides new evidence that nanoparticles, which are present in many food items, may have a substantial and harmful influence on human health. The study investigated the health impacts of food additive E171 (titanium dioxide nanoparticles) which is commonly used in high quantities in foods and some medicines as a whitening agent.

Health: Raw poultry never wash off!

Health experts advise including raw poultry meat wash Poultry meat wash before eating, thoroughly is definitely wrong, so health experts have expressed recently. In the past, it has been said often the other way around, that one should always wash poultry meat. By the Washing of the poultry prior to cooking it can.but health-threatening germs

How ‘superbug’ E. coli clones take over human gut

A ‘superbug’ clone of E. coli has evolved to prevent itself from becoming so dominant that it could potentially wipe out the bacteria from existence, scientists led by the University of Birmingham have discovered. The researchers investigated how and why a clone of E. coli called ST131 — dubbed a ‘superbug’ because it is resistant

Sexual behavior may influence gut microbiome: Researchers say men who have sex with men have unique microbiomes, may impact immune system

A person’s sexual behavior could affect their microbiome and immune system, potentially elevating their risk of HIV infection, according to a new study from researchers at the University of Colorado Anschutz Medical Campus. The study was published last week in the journal PLOS Pathogens. The microbiome, a community of microbes in the gut, play a

New mechanism used by bacteria to evade antibiotics: Surprise survival mechanism could lead to retooled drugs to treat infectious diseases

As bacteria continue to demonstrate powerful resilience to antibiotic treatments — posing a rising public health crisis involving a variety of infections — scientists continue to seek a better understanding of bacterial defenses against antibiotics in an effort to develop new treatments. Now, researchers at the University of California San Diego who combine experiments and

How a common oral bacteria makes colon cancer more deadly

Researchers at the Columbia University College of Dental Medicine have determined how F. nucleatum—a common oral bacteria often implicated in tooth decay—accelerates the growth of colon cancer. The study was published online in the journal EMBO Reports. The findings could make it easier to identify and treat more aggressive colon cancers. It also helps explain

Science Puzzling Out Differences in Gut Bacteria Around the World

THURSDAY, Feb. 14, 2019 — Scientists say nearly 2,000 previously unknown types of bacteria in the human gut have been identified. The human gut hosts many species of microbes, collectively referred to as the gut microbiota. Scientists are working to identify the individual species and understand the roles they play in human health. While investigators
