NewsNew cholera substrains in Bangladesh uncovered by genomic surveillance
Researchers have uncovered two new cholera substrains in a displaced refugee population in southern Bangladesh, where a pre-emptive mass vaccination campaign of over one million refugees was successful in preventing an epidemic.

NewsResearchers discover novel biomarker for sepsis severity
Scientists have identified a novel biomarker that could change the way sepsis is approached and treated.

NewsScorpionfish protein kills drug-resistant bacteria from patients with cystic fibrosis
A scorpionfish protein effectively kills antibiotic-resistant bacteria from patients with cystic fibrosis, escaping an immune response that renders the human version of the protein ineffective.
-
NewsDual wavelengths of light effective against antibiotic-resistant bacterium
Scientists have combined two light wavelengths to deactivate a bacterium that is invulnerable to some of the world’s most widely used antibiotics, giving hope that the regime could be adapted as a potential disinfectant treatment.

NewsResearchers uncover mechanisms underlying Helicobacter pylori-induced gastric cancer
A new study shows how oncoprotein CagA from Helicobacter pylori disrupts Wnt/PCP signalling and promotes gastric carcinogenesis.

NewsApplied Microbiology International announces new president
Professor Jack Gilbert has taken over the reins from Professor Brendan Gilmore as President of Applied Microbiology International (AMI).

NewsScent dogs can detect COVID-19 more rapidly and accurately than current tests
Scent dogs may represent a cheaper, faster and more effective way to detect COVID-19, and could be a key tool in future pandemics, a new review of recent research suggests.

NewsOmicron subvariant BA.5 efficiently infects lung cells
Over the course of evolution of Omicron subvariants, viruses may arise that regain the ability to effectively spread in the lung and cause severe illness in risk patients and people with insufficient immunity, a new study suggests.

NewsBioluminescent bacteria coordinate signalling to colonize squid’s light organ
Researchers reveal how bioluminescent bacteria coordinate their behaviour to colonize the Hawaiian bobtail squid through cellular signaling and cues from the environment.

NewsMerck Prize boosts work on automated air sensor for pandemic pathogens
The $540,000 will fund Khalid Salaita through the next phase of research into an air sensor that can continuously monitor indoor spaces for pathogens that can cause pandemics.

NewsBacteria discreetly living in throat are primary source of Strep A transmission
Breakthrough research has found that Group A Streptococcus (GAS) infections are more likely transmitted from asymptomatic throat carriage than skin-to-skin contact in communities with high rates of infection.

News‘Green’ jobs and roles in emerging STEM industries are not accessible to all, says AMI-sponsored report
A new report looking at the distribution of STEM skills across the UK has found that roles in new and emerging STEM industries are disproportionately concentrated in London and the South East.

NewsBacterial protein may contribute to reduced fertility and birth defects
Scientists have published new findings that emphasize the crucial role of the urinary and genital tract microbiota in adverse pregnancy outcomes and genomic instability that originate in the womb during foetal development.
-
NewsResearchers craft ‘origami DNA’ to control virus assembly
Researchers have used DNA ‘origami’ templates to control the way viruses are assembled. The global team behind the research, published in Nature Nanotechnology, developed a way to direct the assembly of virus capsids – the protein shell of viruses - at physiological conditions in a precise and programmable manner. ...

NewsDiscovery of new gene unveils sex determination in green algae
Scientists determine how female and male reproductive cells develop in volvocine algae.
-
NewsCell wall of Lyme disease pathogen causes lingering symptoms
The National Institutes of Health awarded a College of Agriculture and Life Sciences researcher $2.7 million to understand how the cell wall of the Lyme disease-causing pathogen makes people sick.
