NewsResearchers discover genetic collaboration in harmful algae
A breakthrough study of freshwater harmful algal communities led by Dave Hambright, a Regents’ Professor of Biology at the University of Oklahoma, has discovered that complementary genes in bacteria and algae living in the same algal colonies coordinate the use and movement of nutrients within the colony. This research, funded ...

NewsScientists map role of Porphyromonas gingivalis in chemotherapy resistance
A new paper describes how the bacterium Porphyromonas gingivalis interferes with chemotherapy-induced mitophagy, allowing oral cancer tumors to become resistant to the drug’s effects.

NewsRecombinant protein offers potential as TB booster vaccine
No new vaccine has yet surpassed BCG, which is a highly effective live vaccine and is very effective in preventing tuberculosis in children. Creating a booster vaccine to strengthen immunity in adults is considered a promising and realistic option.

NewsTreating the gut-brain connection with B vitamins could help treat Parkinson’s Disease, study finds
Researchers found a reduction in the gut bacteria of genes responsible for synthesizing essential B vitamins and identified a relationship between the lack of these genes and low levels of agents that help maintain the integrity of the intestinal barrier.

NewsResearchers discover how a deadly strain of salmonella fine-tunes its infection tactics
A new study investigates how pathogens like salmonella change their disease characteristics under fluid shear conditions like those they encounter in our bodies during infection.

NewsStudy shows a high-fat diet may fuel anxiety by disrupting gut bacteria
A new study found that in animals, a high-fat diet disrupts resident gut bacteria, alters behavior and, through a complex pathway connecting the gut to the brain, influences brain chemicals in ways that fuel anxiety.

NewsGiant deep-sea vent tubeworm symbionts use two carbon fixation pathways to grow at record speeds
New research sheds light on how a giant hydrothermal vent tubeworm living in the deep ocean coordinates the two functional carbon fixation pathways used by its symbiotic bacteria to sustain themselves and their host.

NewsTemperature could be the new weapon in the battle against antibiotic resistance
Scientists have found that a small increase in temperature from 37 to 40 degrees Celsius drastically changes the mutation frequency in E. coli bacteria, which facilitates the development of resistance.

NewsBerberine could treat eczema-exacerbated staph infections
Eczema, a skin inflammatory disease that causes dry, itchy and inflamed skin, affects millions worldwide. Eczema is associated with an altered skin microbiome and higher colonization by Staphylococcus aureus. Source: NIAID/NIH Scanning electron micrograph of methicillin-resistant Staphylococcus aureus(MRSA, brown) surrounded by cellular debris. A new study, ...

NewsUpper surface of coastal waters can accumulate bacteria and antibiotics
Antibiotics in the uppermost water surface, known as the sea surface microlayer, can significantly affect the number of bacteria present and contribute to the adaptation of marine bacteria against widely used antibiotics. In new research presented at ASM Microbe, scientists directly assessed the potential effects of antibiotics ...

NewsPlant bacteria deploy phage elements to wipe out the competition
A new study has found that plant bacterial pathogens are able to repurpose elements of their own phages to wipe out competing microbes, suggesting such elements could someday be harnessed as an alternative to antibiotics.

NewsDiscovery of ancient microfossil sheds light on adaptive evolution of sulfate-reducing bacteria
A 518-million-year-old microbial fossil from China identified as an ancient sulfate-reducing bacterium sheds light on the adaptive evolution of sulfate-reducing bacteria in response to Earth’s oxygenation events.

NewsSyphilis cases are rising, but many people don’t know the symptoms
Syphilis cases are on the rise around the globe, but many Americans don’t know the symptoms. Just over half know that a case of syphilis can be permanently cured and most either mistakenly think there is a vaccine to prevent it or are unsure.

NewsStudy reveals role of fathers in seeding the microbiota of newborns
A new paper shows the important contributions that fathers make to the composition of microbes colonizing a baby’s gut, and confirms that maternal fecal microbiota transfer (FMT) in babies born by C-section can help to correct microbiota disturbances.

NewsInnovative phage lysin HY-133 enters phase I clinical study
HYpharm’s innovative preventive agent HY-133 has reached the first clinical trial phase. HY-133 is specifically effective against Staphylococcus aureus including multi-resistant strains and is intended to combat its colonisation in the nose.

NewsTwo types of polymicrobial infections in chronic lung diseases
Chronic lung diseases are often accelerated and exacerbated by polymicrobial infections. An international study team led by MedUni Vienna has identified two types of these so-called dysbioses in cystic fibrosis. They display distinct ecology and are also likely to respond differently to treatment. The study was published in the journal ...

NewsVirus-like nanoparticles control multicellular organization and reproduction of host bacteria
Researchers examining Streptomyces davawensis, an actinomycete species, discovered that it produces virus-like particles that facilitate host reproduction.

NewsTwo ways that members of the microbiome fight salmonella infections
Researchers have identified two mechanisms through which Klebsiella bacteria combat the spread of salmonella in the gut.

NewsSoil bacteria respire more CO2 after sugar-free meals
Researchers have tracked the pathways of a mixture of plant waste as it moves through bacteria’s metabolism to contribute to atmospheric CO2. Microbes respire three times as much CO2 from lignin carbons compared to cellulose carbons, they say.

NewsBartonella DNA found in blood of patients with psychosis
A new study has found that patients diagnosed with schizophrenia or another psychotic disorder are three times more likely to have Bartonella DNA in their blood than adults without these disorders.
