Newly found bacteria fights climate change, soil pollutants
Cornell University researchers have found a new species of soil bacteria that is particularly adept at breaking down organic matter, including the cancer-causing chemicals that are released when coal, gas, oil and refuse are burned.
Designer Probiotic Treatment for Cancer Immunotherapy
Columbia Engineers have engineered probiotics to safely deliver immunotherapies within tumors, including nanobodies against two proven therapeutic targets—PD-L1 and CTLA-4. Continuously released by bacteria, the drugs continue to attack the tumor after just one dose, facilitating an immune response resulting in tumor regression. The versatile probiotic platform can also be used to deliver multiple immunotherapies simultaneously, enabling the release of effective therapeutic combinations within the tumor for more difficult-to-treat cancers like colorectal cancer.
Study: Diet Makes a Difference in Fight Against Hospital-Acquired Infection
Popular diets low in carbs and high in fat and protein might be good for the waistline, but a new UNLV study shows that just the opposite may help to alleviate the hospital-acquired infection Clostridioides difficile. The results appeared in a study published Feb. 11 in mSystems, an open access journal of the American Society for Microbiology.
Drug Lord’s Hippos Make Their Mark on Foreign Ecosystem
Scientists published the first assessment of the impact that invasive hippos imported by drug lord Pablo Escobar are having on Colombian aquatic ecosystems. The hippos are changing the area’s water quality by importing large amounts of nutrients and organic material from the surrounding landscape.
New Portable Tool Analyzes Microbes in the Environment
Imagine a device that could swiftly analyze microbes in oceans and other aquatic environments, revealing the health of these organisms – too tiny to be seen by the naked eye – and their response to threats to their ecosystems. Rutgers researchers have created just such a tool, a portable device that could be used to assess microbes, screen for antibiotic-resistant bacteria and analyze algae that live in coral reefs. Their work is published in the journal Scientific Reports.
Disarming bacteria with mucus and phages
Millions of people are treated with antibiotics each year for infections or as a preventative measure. Two teams of NIBIB-funded scientists have been working to find alternative solutions for treating bacterial infections, especially antibiotic-resistant bacteria.
‘Are Noncommunicable Diseases Communicable?’ Rutgers Experts Available to Discuss Paper in Science Today
New Brunswick, N.J. (Jan. 16, 2020) – Rutgers professors Maria Gloria Dominguez-Bello and Martin J. Blaser are available to discuss a paper in the journal Science today on whether diseases long thought to be noncommunicable – such as cardiovascular diseases, cancer…
Surprising Beauty Found in Bacterial Cultures
Researchers at University of California San Diego have discovered that when certain microbes pair up, stunning floral patterns emerge.
Delivering TB Vaccine Intravenously Dramatically Improves Potency, Study Shows
Worldwide, more people die from tuberculosis than any other infectious disease, even though the vast majority were vaccinated. The vaccine just isn’t that reliable. But a new Nature study finds that simply changing the way the vaccine is administered could dramatically boost its protective power.
Trial Suggests Babies in Intensive Care Can be Better Protected From Parental Bacteria
For sick or prematurely born babies spending their first days of life in a hospital’s neonatal intensive care unit (NICU), the soothing voice and gentle touch of a loving parent can have a tremendous impact toward a positive outcome — that is, unless mom or dad’s visit leaves the infant with something extra: a dangerous bacterial infection.
Why It Matters: Prescription for Disaster
Bacteria are becoming increasingly resistant to antibiotics. A major cause is their overuse in both humans and animals. At the same time, a lack of financial incentives is setting back efforts to discover new classes of antibiotics. The problem is both global and local, and without new initiatives, many common medical conditions could become deadly once again.
Gut Bacteria Found to Have a Shocking Secret
Scientists studied how the bacteria transport electrons across their cell wall. The bacteria use a method that’s different from other, known electricity-producing bacteria. They also found that hundreds of other bacterial species use this same process.
Hard as a rock? Maybe not, say bacteria that help form soil
Research published this week by University of Wisconsin–Madison scientists shows how bacteria can degrade solid bedrock, jump-starting a long process of alteration that creates the mineral portion of soil.
Superbug battle: Bacteria structure may be key to new antibiotics
Cornell researchers have uncovered the structure of a regulatory mechanism unique to bacteria, opening the door for designing new antibiotics targeted to pathogens.
Probiotic Bacteria: A Double-Edged Sword
Israeli and American scientists have discovered that administering probiotics in hospital intensive care units may lead to blood infections, and in some cases the adverse effects could outweigh the potential benefits.
Bird bacteria is key to communication and mating
Birds use odor to identify other birds, and researchers at Michigan State University have shown that if the bacteria that produce the odor is altered, it could negatively impact a bird’s ability to communicate with other birds or find a mate.
Bacterial Lifestyle Steers the Evolution of Antibiotic Resistance
How bacteria live – whether as independent cells or in a communal biofilm – determines the course of their evolution, with implications for drug-resistant infections.
Many cooks don’t spoil the broth: Manifold symbionts prepare their host for any eventuality
Deep-sea mussels, which rely on cooperative symbiotic bacteria for their food, harbor a surprisingly high diversity of these bacterial “cooks”: Up to 16 different bacterial strains live together in the mussel’s gills, each with its own abilities and strengths. Thanks to this diversity of symbiotic bacterial partners, the mussel is prepared for all eventualities. The mussel bundles up an all-round carefree package, a German-Austrian research team including Jillian Petersen from the University of Vienna and Rebecca Ansorge and Nicole Dubilier from the Max-Planck-Institute for Marine Microbiology now reports in Nature Microbiology.
Scientists Discover New Antibiotic in Tropical Forest
Scientists from Rutgers University and around the world have discovered an antibiotic produced by a soil bacterium from a Mexican tropical forest that may help lead to a “plant probiotic,” more robust plants and other antibiotics. Probiotics, which provide friendlier bacteria and health benefits for humans, can also be beneficial to plants, keeping them healthy and more robust. The new antibiotic, known as phazolicin, prevents harmful bacteria from getting into the root systems of bean plants, according to a Rutgers co-authored study in the journal Nature Communications.
High Levels of Fecal Bacteria Found in Lower Raritan River
New Brunswick, N.J. (Sept. 17, 2019) – High levels of fecal bacteria have often been found at six new water sampling sites in the lower Raritan River since May, according to a Rutgers-coordinated monitoring program that included more than 20…

UniSA nano scientists stop superbugs in their tracks
A team of researchers led by the University of South Australia has discovered a way to find and beat superbugs, providing a critical breakthrough against many deadly infectious diseases.
