NewsSource of sticking power for emerging fungal pathogen is uncovered
A previously uncharacterized adhesin protein specific to a human fungal pathogen plays a crucial role in the fungus’s ability to colonize a variety of living and non-living surfaces, and in its virulence, according to a new study.

FeaturesBiodeterioration and bioconservation of Mayan historical monuments: two sides of a coin
How understanding the microbiology of ancient sites is allowing researchers to preserve cultural heritage.

NewsOral health deteriorates before and after bariatric surgery
Researchers who analyzed saliva, oral microbiota and dental health of volunteers before and after gastroplasty found an increase in caries and periodontitis, as well as alterations in salivary inflammatory markers.

NewsEfficient oil-eating bacteria cooperate to maximize dining capacity
Researchers find an oil-degrading bacterium Alcanivorax borkumensis forms biofilms that consume the oil by surrounding and adhering strongly to the oil-water interface.

NewsCargo system inhibits E.coli biofilms with a fraction of the antibiotic dose
Scientists have designed a bacteria-targeted cargo system that is capable of inhibiting a quinolone resistant Escherichia coli biofilm using much lower levels of antibiotic. The researchers, from Koç University School of Medicine in collaboration with College of Science, Department of Chemistry, encapsulated the antibiotic ciprofloxacin into superparamagnetic iron oxide nanoparticles ...

NewsFatty acids govern cannibalism in beneficial rhizosphere bacterium
A new study reveals that bacillunoic acids-mediated cannibalism enhances biofilm formation in Bacillus velezensis SQR9.

NewsEngineered microbe targets fungal scourge of golf courses
A patented beneficial microbe is found to be promising for disarming fungal pathogens that affect turfgrass.

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.

NewsBioleaching bacteria exploit cracks to form biofilms on REE rocks
Bioleaching bacteria home in on and around grooves and crevices in rare earth element-bearing rocks and form biofilms, potentially offering a route to making the process more efficient, a new study shows.

NewsHospital infection shows dual colonisation strategy
Researchers have uncovered why one of the most dangerous nosocomial pathogens, Pseudomonas aeruginosa, is so difficult to combat - it follows a dual strategy, with some bacteria colonizing the tissue surface while others spread in the body.

NewsBioactive glass doped with silver delivers longer-lasting antimicrobial wound protection
Researchers at the University of Birmingham have demonstrated that silver retains antimicrobial activity for longer when it is impregnated into ‘bioactive glass’, and shown for the first time how this promising combination delivers more long-lasting antimicrobial wound protection than conventional alternatives.

NewsEarly warning sensor changes colour when wound becomes infected
A team at Queen’s University Belfast have developed a non-invasive sensor that changes colour when a wound becomes infected, alerting healthcare staff hours before symptoms become visible to the eye.

NewsCholera bacteria form aggressive biofilm to kill immune cells
Resarchers have discovered that the bacterial pathogen that causes cholera forms a novel type of bacterial community on immune cells: an aggressive biofilm that is lethal for the cells.

NewsBacterial species teams with Streptococcus to boost tooth decay
Researchers have discovered that a bacterial species called Selenomonas sputigena can have a major role in causing tooth decay.

NewsUltrasound helps break bacterial barriers in chronic treatment-resistant wounds
Researchers have developed a new strategy combining palmitoleic acid, gentamicin, and non-invasive ultrasound to improve drug-delivery into chronic wound infections.
-
NewsBacteria evolve antibiotic resistance quickly by rejigging pumps
Bacteria can rapidly evolve resistance to antibiotics by adapting special pumps to flush them out of their cells, according to new research from the Quadram Institute and University of East Anglia.

NewsDynamics of biofilm in backwashed sand filters
Scientists have uncovered the temporal dynamics of both the concentration of micropollutants and the microbial community in sand filters after backwashing, to indicate the optimal intervals for backwashing slow sand filters for micropollutant removal from drinking water.

NewsPhage delivers double whammy against biofilms
A novel bacteriophage isolated from sewage water not only kills its target bacteria in the Klebsiella oxytoca complex but was unexpectedly found to be capable of disrupting biofilms produced by these bacteria.
-
NewsBacteria’s antibiotic-evading super polymers do best in harsh conditions of the gut
New research has shown that gut bacteria’s extracellular appendages known as F-pili are stronger in the turbulent conditions of the gut, helping the bacteria transfer resistance genes to each other more efficiently and to clump into ‘biofilms’ – protective bacterial consortia – that help them fend off antibiotics.

NewsMultiple species band together in polymicrobial biofilms to defeat bacterial vaginosis treatments
Scientists will have to rethink their approach to treating bacterial vaginosis due to the presence of a multi-species biofilm that complicates testing.
