Genetic analysis of Streptococcus pyogenes reveals multiple mutations, including a key change in the fhuB gene, that influence the bacteria’s ability to cause severe invasive infections.
Gliding multicellular cyanobacteria results from cellular coordination, the loss of which results in the collapse of orderly back-and-forth movement of filaments and in filament buckling.
A pioneering Bolivian seroepidemiological study employed innovative serological and neutralization assays as highly effective complements to genomic surveillance, delivering critical insights into SARS-CoV-2 variant circulation and informing public health strategies.
Dysregulated myelopoiesis is identified as a driver of nutritionally acquired immunodeficiency that persists after refeeding and nutritional recovery, indicating exposure to food scarcity may be an immunologic risk factor.
In methicillin-resistant Staphylococcus aureus, evolution of bacteriophage resistance causes trade-offs that re-sensitize the bacteriato β-lactam antibiotics.
A single β-lactam exposure rapidly drives stable multidrug resistance in RecA-deficient bacteria through an SOS-independent mechanism involving oxidative stress-induced mutagenesis and antibiotic-driven selection.
