Bacteria's "suicidal" immune system boosts antibiotic power against cholera

Bacteria have an immune system that protects them against viruses known as bacteriophages. A research team from the Universities of Tübingen and Würzburg has now shown how this immune system enhances the effect of specific antibiotics against the cholera pathogen Vibrio cholerae.

New Omicron variants relearn immunity dodging tricks

Recent SARS-CoV-2 variants such as BA.4 and BA.5 developed abilities missing from the first Omicron variants that allowed them to overcome humans' innate immunity, according to research from UCL.

Swedish blood donor study reveals high prevalence of undiagnosed TBE infections

The number of infections by the tick-borne TBE virus that are not detected by health services is far higher than previously assumed.

Researchers uncover role of persister cells in antibiotic resistance

Antibiotic overuse can lead to antibiotic resistance, but classic antibiotic resistance might not completely explain why antibiotics sometimes fail.

Gum bacteria fuel COPD through immune cell activation

Severe gum disease has been linked to the progression of chronic obstructive pulmonary disease, or COPD, but an understanding of how the connection plays out in the immune system remains unclear.

Drug-resistant Candida: Study uncovers evolutionary tricks of a fungal pathogen

Global fungal infections, which affect one billion people and cause 1.5 million deaths each year, are on the rise due to the increasing number of medical treatments that heighten vulnerability.

New molecule targets key protein in autoimmune diseases

Scientists from Scripps Research have developed a small molecule that blocks the activity of a protein linked to autoimmune diseases, including systemic lupus erythematosus (SLE) and Crohn's disease.

Blocking sugar molecules stops flu virus spread in mice

Scientists have long known that some viruses and bacteria begin infections by latching first onto sugar molecules on the surfaces of cells lining the sinuses and throat of mammals, including humans.

New algorithm proves to be a powerful tool for detection and identification of novel bacterial organisms

Researchers developed the NOVA algorithm to systematically analyze bacterial isolates unidentified using traditional methods such as matrix-assisted laser desorption ionization-time of flight mass spectrometry and partial 16S rRNA gene sequencing using whole genome sequencing.

SARS-CoV-2 BA.2.86 shows increased lung targeting despite vaccine effectiveness

New research shows that the recently emerged BA.2.86 omicron subvariant of the virus that causes COVID-19 can be neutralized by bivalent mRNA vaccine-induced antibodies in the blood, which explains why this variant did not cause a widespread surge as previously feared.
