New 'interspecies communication' strategy between gut bacteria and mammalian hosts uncovered
Bacteria in the gut do far more than help digest food in the stomachs of their hosts, they can also tell the genes in their mammalian hosts what to do. A study published today in Cell describes a form of 'interspecies communication' in which bacteria secrete a specific molecule -- nitric oxide -- that allows them to communicate with and control their hosts' DNA, and suggests that the conversation between the two may broadly influence human health.

Chemical added to consumer products impairs response to antibiotic treatment
Triclosan exposure may inadvertently drive bacteria into a state in which they are able to tolerate normally lethal concentrations of antibiotics -- including those antibiotics that are commonly used to treat urinary tract infections (UTIs). (2019-02-21)

Cocktail of common antibiotics can fight resistant E. coli
Scientists from the Novo Nordisk Foundation Center for Biosustainability have discovered that a combination of two common antibiotics is able to eliminate multi-drug resistant E. coli causing urinary tract infections.

Cervical microbiome may promote high-grade precancerous lesions
Infections with a Human Papillomavirus (HPV) cause 99 percent of cervical cancer cases, and the disease's first sign is often the appearance of precancerous lesions on a woman's cervix. But bacteria may play an important role, too. New research suggests that the cervical microbiome may influence HPV infection more than researchers previously thought. (2019-02-19)

High fat diet linked to unfavorable changes in gut bacteria and inflammatory triggers

Suicide system in tuberculosis bacteria might hold key to treatment
Tuberculosis (TB) is one of the top ten causes of death worldwide. The genome of the bacterium that causes TB holds a special toxin-antitoxin system with spectacular action: once the toxin is activated, all bacterial cells die, stopping the disease. An international research team co-led by the Wilmanns group at EMBL in Hamburg investigated this promising feature for therapeutic targets. They now share the first high-resolution details of the system in Molecular Cell. (2019-02-18)

Tuberculosis: Commandeering a bacterial 'suicide' mechanism

NUS marine scientists find toxic bacteria on microplastics retrieved from tropical waters
A team of marine scientists from the National University of Singapore had uncovered toxic bacteria living on the surfaces of microplastics (which are pieces of plastic smaller than 5 millimetres in size) collected from the coastal areas of Singapore. These bacteria are capable of causing coral bleaching, and triggering wound infections in humans. The team also discovered a diversity of bacteria, including useful organisms - such as those that can degrade marine pollutants like hydrocarbons - in the plastic waste. (2019-02-11)

Hard-to-detect antibiotic resistance an underestimated clinical problem
When antibiotics are used to treat bacteria susceptible to them, the treatment usually works. Nevertheless, the antibiotic chosen is sometimes ineffective.

Better assessing bacteria sensitivity to antibiotics could change how drugs are prescribed
We rely on antibiotics to treat bacterial infections, but the rise of antibiotic-resistant bacteria forces doctors and patients to contend with shifting treatment plans. Furthermore, current laboratory tests to determine what bacteria is causing a particular infection takes days to complete and can be too late for the patient. Mechanical engineers in Korea recently developed a microchip antibiotic testing platform that takes only six to seven hours to determine the appropriate medication. (2019-02-05)

New anti-CRISPR proteins discovered in soil and human gut
Scientists from the Novo Nordisk Foundation Center for Biosustainability (DTU) have found four new anti-CRISPR proteins that are distributed across different environments. The new study published in Cell Host & Microbe suggests that some anti-CRISPR proteins are more widespread in nature than previously anticipated. These anti-CRISPRs can potentially be used to regulate the activity of CRISPR-Cas9 systems better in the future. (2019-02-05)

Whopping big viruses prey on human gut bacteria
Sequencing gut microbiomes typically turns up new microbes and other denizens of the intestinal tract, including viruses or phages that prey on these microbes. A new UC Berkeley study has discovered the largest phages every found in humans, with genomes 10 times the average and larger than the genomes of the smallest bacteria. They target bacteria found primarily in people eating non-Western diets. Their large size blurs the line between life and non-life. (2019-01-28)
