NewsGenetic sequencing uncovers unexpected source of pathogens in floodwaters
Local rivers and streams were the source of the Salmonella enterica contamination along coastal North Carolina after Hurricane Florence in 2018 – not the previously suspected high number of pig farms in the region.
-
NewsResearch addresses mystery of why diversity in plant species causes higher farming yield
A new study shows how a boost in agricultural yield comes from planting diverse crops rather than just one plant species - soil pathogens harmful to plants have a harder time thriving.

NewsGenetics of host plants determine what microorganisms they attract
Plants often develop communities with microorganisms in their roots, which influences plant health and development. It is unclear whether genetic variation in the host plants plays a role in recruitment of these microbes.

NewsAMR leads to more deaths and illnesses in the WHO African region than anywhere else
More than 1.05 million deaths were associated with antimicrobial resistance (AMR) and 250,000 deaths were attributable to AMR in the WHO African region, posing an unprecedented health threat.

NewsNew weapon against the super tough C diff bacteria shows promise
A researcher has demonstrated that a newer generation tetracycline antibiotic, Omadacycline, may be a promising tool in combating the resilient bacteria Clostridioides difficile (C diff), which causes an infection often picked up in hospitals.

NewsScientists discover Ebola virus uses tunnelling nanotubes to infect cells
A new study indicates that Ebola virus creates and uses intercellular tunnels to move from cell to cell within the human body and evade treatments.
-
NewsGiant bacterium uses unique processes to power itself
Scientists have for the first time described the full genome of one species of the Epulopiscium family of giant bacteria, which they’ve named Epulopiscium viviparus.

NewsKeto diet protects against epileptic seizures by changing gut microbiome
Researchers have demonstrated that the changes the high-fat, low-carbohydrate ketogenic diet causes in the human gut microbiome can confer protection against seizures in mice.
-
NewsLittle bacterium may make big impact on rare-earth processing
Scientists show that genetically engineering Vibrio natriegens could improve the efficiency for the purification of elements found in smartphones, computers, electric cars and wind turbines, and could even boost global economic supply chains.

NewsPhotodynamic action weakens resistance to antibiotics in bacteria that attack airways
A study of photodynamic inactivation (PDI) showed it has a novel capacity to modify bacterial sensitivity to antibiotics according to dosage, reducing the resistance and persistence of both standard and clinical strains.
-
NewsResearchers discover how to sabotage antibiotic-resistant ‘superbugs’
Scientists say they have learned how to sabotage a key piece of machinery that pathogens use to infect their host cells, and have developed a test to identify the next-generation drugs to target this vulnerable cellular machinery.

NewsB cell deficient patients gain protective T cell immunity after SARS-CoV-2 vaccination, infection
Researchers found that vaccinated B cell-deficient individuals had significantly reduced risk of moderate and severe disease in comparison to those who were not vaccinated, despite an absence of anti-spike antibody responses.
-
NewsToothbrushing tied to lower rates of pneumonia among hospitalized patients
Researchers found that hospital-acquired pneumonia rates were lower among patients who received daily toothbrushing compared to those who did not.
