NewsNew bacterial blueprint will help fight antibiotic resistance
Scientists have gained high-res structural insights into a key bacterial enzyme, which may help chemists design new drugs to inhibit it and thus suppress disease-causing bacteria.
-
NewsScientists uncover secrets of bacteria threatening Vidalia onion production
Researchers have confirmed which genes in the bacterial pathogen Pantoea ananatis high virulence cluster are essential and which genes contribute partially to a disease that causes rotting symptoms in Vidalia onions.

NewsAlarming antibiotic resistance discovered in war-torn Ukraine
Microbiologists investigating bacterial resistance among the war-wounded Ukrainian patients treated in hospitals have warned that the entire European region is under threat after finding that many were affected by bacteria that exhibited an extremely high level of antibiotic resistance.

NewsNatural molecule added to toothpaste may help prevent plaque and cavities
Scientists have discovered that 3,3′-Diindolylmethane (DIM), a naturally occurring molecule also known as bisindole, reduces the biofilms that produce plaque and cavities by 90% and is also found to have anti-carcinogenic properties.

NewsNearly half of TB cases in prisons worldwide go undetected
In the first global assessment of tuberculosis among incarcerated people, a new study found consistently high TB case rates and low case detection in prisons.
-
NewsNew enzyme designed using Antarctic bacteria and computer calculations
For the first time, researchers have succeeded in predicting how to change the optimum temperature of an enzyme using large computer calculations and based on a cold-adapted enzyme from an Antarctic bacterium.
-
NewsFuture medicines could feature ingredients targeting bacterial motility and chemotaxis
Future medicines will probably be made up of a cocktail of compounds that inhibit different bacterial targets, including some that act against their motility and chemotaxis mechanisms, a new review suggests.

OpinionMicrobial hydrogen cycling - the good, the bad and the ugly
With global populations looking likely to top 10 billion by the year 2050, the practices that we use to grow food need to adapt in kind - and what better way is there but to harness the innate power of microbes!

News‘Hospital pathogen’ widespread in Vietnam’s environment
A pathogen considered to be a cause of hospital infection is widespread in Vietnam, turning up in farm soil and pig faeces as well as hospital beds and toilet floor surfaces, with 70% of isolates found to be resistant to at least one class of antimicrobials.

NewsMicroneedle array with antibacterial nanoparticles targets acne
Researchers have designed a new microneedle patch engineered with ultrasound-responsive zinc-based metal-organic framework (MOF) antibacterial nanoparticles, promising pain-free delivery to treat bacterial infection on skin tissue and facilitate skin repair.
-
NewsMolecular insights may inform new treatments for drug-resistant TB
Researchers have used state-of-the-art imaging to examine two new compounds that target ATP synthase, potentially stopping TB bacteria from producing the energy they need to survive.
-
NewsResearchers can use ultrasound to control orientation of small particles, including bacteria
Using ultrasound technology and a nozzle, scientists have separated, controlled and ejected different particles based on their shape and various properties, with implications for drug delivery and bioprinting.

NewsD-amino acids play role in cholera bacterium’s bid to escape
Cholera bacteria use specific D-amino acids to escape unfavourable niches and form complex ecological systems, a new study shows.
-
NewsStreptomycetes reveal their arsenal of signalling compounds
Streptomyces bacteria produce a group of signalling molecules that trigger a variety of processes, a new study shows.
-
NewsSmall ruminant farms could spread human diarrhoea causing bug
Goat and sheep dairy farms are a potential transmission source for a bacteria that can cause human gastroenteritis, according to a new study.

NewsStudy unveils gene expression of photosynthetic symbiont in marine diatom
A new study explores the genetic expression of a photosynthetic symbiont that lives inside an abundant marine organism.
-
NewsRule-breaking anoxic bacteria infected with viruses
Researchers investigating why green and purple bacteria in northeast Washington didn’t obey the usual rules found they had genes in their metagenome that came from viruses.
-
NewsLupus flare-ups linked to Ruminococcus blautia gnavus blooms in gut
A new study found that bacterial blooms of the gut bacterium Ruminococcus blautia gnavus occurred at the same time as disease flare-ups in five of 16 women with lupus of diverse racial backgrounds studied over a four-year period.
