NewsThe geometry of life: Physicists determine what controls biofilm growth
The fitness of a biofilm is largely impacted by the contact angle that the biofilm’s edge makes with the substrate - and this geometry has a bigger influence on fitness than anything else, including the rate at which the cells can reproduce.

NewsE. coli variant may cause antimicrobial resistance in dogs and humans
Researchers studying antimicrobial-resistant E. coli – the leading cause of human death due to antimicrobial resistance worldwide – have identified a mechanism in dogs that may render multiple antibiotic classes ineffective.

NewsKenyan crop contamination outbreak inspires grad student to improve rice storage
A new study shows that proper rice storage conditions to reduce aflatoxin risk after harvest include a temperature below 20 degrees Celsius, or 68 degrees Fahrenheit, and relative humidity below 75 per cent.

NewsMost Salmonella illnesses from chicken caused by few products with high levels of virulent strains
A new study shows that few products with high levels of very virulent Salmonella strains are responsible for most of the illnesses from raw chicken parts, suggesting regulation efforts should focus on detecting and preventing high-risk contamination.

NewsAdvanced imaging reveals how a parasitic ‘kiss’ alters cell metabolism
Researchers have described how Toxoplasma infection changes host cell metabolism over the course of infection using the power of optical metabolic imaging (OMI) for the first time.
-
NewsRespiratory bacteria ‘turns off’ immune system to survive
Researchers have identified how a common bacterium is able to manipulate the human immune system during respiratory infections and cause persistent illness.

NewsNIH funds consortium to accelerate development of new TB treatments
A new consortium has been awarded a five-year, $31 million grant from the National Institutes of Health’s National Institute of Allergy and Infectious Diseases to accelerate the development of faster, more effective treatment regimens for tuberculosis.

NewsPhage-derived enzyme targets biofilms to mitigate acute graft-versus-host disease
Scientists investigating acute graft-versus-host disease probe gut microbiome to detect presence of a bacteriophage-derived enzyme known as endolysin, exhibiting potent antibacterial activity specifically targeting E. faecalis.

NewsNew plasma jet technology effectively treats fungal nail infections
Researchers used portable pulsed cold air plasma jet device to kill Trichophyton rubrum in nails. They established a nail model of onychomycosis infection, and then used PP-CAPJ to treat nails of different thicknesses.

OpinionOnce-subtropical Vibrio infections on the move along coastlines
As new stretches of coastline become vulnerable to potential Vibrio outbreaks in a warming aquatic environment, Applied Microbiology International member Elizabeth Archer examines how human health is inextricably linked with ocean health.
-
NewsWHO updates laboratory biosecurity guidance
WHO recently issued updated guidance for national authorities and biomedical laboratories to manage biological risks, including strengthening of cybersecurity measures and reducing risks from new technologies.

NewsResearchers develop predictive model for cross-border COVID spread
A study on the spread of infections across Nordic borders from spring until the end of 2020 sheds light on the efficacy of cross-border travel restrictions, helping to better understand which measures actually make a difference.
-
NewsScientists uncover molecular basis of how potential anti-Covid drug binds to viral N-glycan
Researchers evaluating the potential of naturally occurring pradimicin A (PRM-A) as a new anti-SARS-CoV-2 drug that suppresses SARS-CoV-2 transmission investigated how exactly PRM-A binds to the viral N-glycans.

NewsPublic fails to appreciate risk of consuming raw milk, survey finds
Fewer than half of U.S. adults know that drinking raw milk is less safe than drinking pasteurized milk and many Americans do not understand the risks of consuming raw milk, according to a new health survey.

NewsSRI is developing a new malaria treatment that aims to protect from the disease
The injectable formulation is affordable, easily administered, and could potentially provide months of protection from the potentially fatal disease.

News Bacteria detected in tattoo and permanent makeup inks
Researchers have detected anaerobic and aerobic bacteria in commercial tattoo and permanent makeup inks. The findings demonstrate that the inks could be a source of human infections.

NewsSurvey finds many have misconceptions about sexually transmitted infection risk
Sexually transmitted infections (STIs) are on the rise in the U.S., including an 80% increase in syphilis over a five-year period, but a new survey finds many Americans have misconceptions on how STIs are spread and who should be treated.

NewsDiagnostic stewardship approach to C. diff reduces unnecessary testing
Revised rules for when Clostridioides difficile tests could be ordered helped to reduce inappropriate testing by 20%, which in turn can help rein in the overtreatment of patients.
