Antibiotics

Bacteria that cause typhoid fever are becoming increasingly resistant to common antibiotics worldwide, a new analysis indicates. Resistant strains of Salmonella enterica serovar Typhi (S Typhi) — almost all originating in South Asia — have spread across borders nearly 200 times since 1990. Until now, analysis has been limited by…

It is essential to quickly identify the infection and select the right combination of sensitive…

Diversity is an omnipresent element in clinical practice: in the genome, in the environment, in patients' lifestyles and habits. Precision medicine addresses the variability of the individual to improve diagnosis and treatment. It is increasingly used in specialties such as oncology, neurology, and cardiology. A personalized approach has many objectives,…

The findings are presented at ASM Microbe 2022, the annual meeting of the American Society for Microbiology. In a recent…

Robust disease surveillance, vaccine manufacturing and distribution, and antibiotics management are tools that should be strengthened. A young woman reacts as a health worker injects her with the Ebola vaccine, in Goma, Democratic Republic of Congo. We've learned many lessons about the spread of disease; now we need to strengthen…

Using advanced microscopy techniques, researchers at Karolinska Institutet and Stockholm University in Sweden have visualized in unprecedented detail the machinery that the cells' powerhouses, the mitochondria, use to form their proteins. The results, which are published in Nature, raise hopes of more specific antibiotics and new cancer drugs in the…

A model has been developed to help the Food Standards Agency (FSA) assess the risk for consumers from AMR associated bacteria in food. Antimicrobial resistance (AMR) is where microorganisms survive antimicrobial treatments such as antibiotics and make infections more difficult to treat. To test the tool on various pathogens and…
