NewsBacteria-fighting viruses team up to treat drug-resistant superbugs
Researchers screened a library of bacteriophages to find combinations of the viruses that can work together to fight antibiotic-resistant Klebsiella pneumoniae infections.

NewsScientists can pinpoint bacterial needle in haystack using fluorescence
Bacterial troublemakers are able to survive antibiotics and are not detected by diagnostic antibiotic resistance testing. A new method has been developed to look at single bacteria and to find the antibacterial resistant ones, or the troublemakers, among them.

NewsScientists reveal how doxycycline for STI prevention affects the gut microbiome
Taking a dose of the oral antibiotic doxycycline after a high-risk sexual encounter has dramatically reduced the incidence of sexually transmitted infections (STIs) in places where the strategy is being tried. Source: NIAID Capsules of the antibiotic doxycycline Despite its effectiveness, the new strategy, known ...

NewsGut bacteria engineered to act as tumor GPS for immunotherapies
Cancer researchers have engineered gut derived E. coli bacteria to express immune-activating cytokines on their surfaces, with the idea that the bacteria would move into tumors and induce potent immune responses.

NewsNovel Pseudomonas species supports plant growth at high altitudes
Scientists have discovered a new Pseudomonas species isolated from cold Himalayan soil that helps to promote plant growth, offering potential as a bio-inoculant for sustainable agriculture in high-altitude regions.

NewsStudy identifies potential novel drug to treat tuberculosis
A new study demonstrates that a novel semi-synthetic compound can be derived from natural compounds to produce potent activity against Mycobacterium tuberculosis, including multi-drug resistant strains.

NewsWastewater bacteria can break down plastic for food
Researchers have discovered how cells of a Comamonas bacterium break down plastic for food. First, they chew the plastic into small pieces, then secrete an enzyme that breaks down the plastic further, and finally use a ring of carbon atoms as a food source.

NewsPlant compound used in traditional medicine may help fight tuberculosis
A compound found in African wormwood — a plant used medicinally for thousands of years to treat many types of illness — could be effective against tuberculosis, according to a new study.

NewsFilament structure activates and regulates CRISPR-Cas ‘protein scissors’
Researchers have revealed the structure of the CRISPR-Cas ‘protein scissors’ found in bacteria and provided mechanistic details on how they function.

NewsScientists study how a bacterium becomes a permanent resident in a fungus
To study the beginnings of endosymbiosis between two organisms, a team of researchers initiated such partnerships in the laboratory and observed what exactly happens at the beginning of a possible endosymbiosis.

NewsResearchers unravel mystery of dormancy in food pathogens for more effective elimination
The detection tests commonly used to check for the absence of microbes in hospitals or the agri-food industry are based on microbial growth, i.e. the laboratory cultivation of microorganisms from a sample to be checked. If no micro-organisms appear during culturing, the sample is considered safe. Source: INRAE ...

NewsResearchers identify likely culprit that turns classical Klebsiella pneumoniae into a drug-resistant killer
A hypervirulent strain of Klebsiella pneumoniae can infect and severely sicken otherwise healthy people. Researchers have identified a likely culprit that is causing the hypervirulence.

NewsBacterial contamination and microplastics threaten Colombia’s largest and most productive coastal lagoon
A study warns of the presence of potentially pathogenic bacteria in microplastics extracted from water, sediments and the digestive tract of fish in the Ciénaga Grande de Santa Marta, the largest and most productive coastal lagoon system in the Colombian Caribbean.

NewsStudy shows how emissions from Brazilian Pantanal’s soda lakes contribute to climate change
Characterized by high pH and salinity, these soda lakes have practically dried up because of rising temperatures, changing rainfall patterns, and wildfires. The study shows how the local microbial community influences greenhouse gas emissions.

NewsResearchers discover mechanism driving immune perturbations after severe TB infections
Rsearchers have discovered a mechanism that drives the long-term decline in immune response that is observed after tuberculosis (TB) has been successfully treated.
-
NewsPromising TB therapy safe for patients with HIV
A therapy showing promise to help control tuberculosis (TB) does not interfere with combined antiretroviral therapy (cART), according to new research.

NewsSwedish research on antibiotic pollution becomes UN declaration after 17 years
In 2007, researchers at the University of Gothenburg, Sweden published the first in a series of studies showing massive pollution with antibiotics from pharmaceutical factories in India. In connection with the ongoing UN General Assembly in New York, a declaration was approved that underlines the risks and calls for measures ...

NewsPresence of bacteria in soil makes flowers more attractive to pollinators
Bacteria that live in soil and help roots fix nitrogen can boost certain plants’ capacity to reproduce by enhancing the attractiveness of the plant’s flowers to pollinators via a relationship known as mutualism that is widespread in plants and animals.
