Staphylococcus aureus News and Research

RSS

Staphylococcus aureus is a spherical bacterium (coccus) which on microscopic examination appears in pairs, short chains, or bunched, grape-like clusters. These organisms are Gram-positive. Some strains are capable of producing a highly heat-stable protein toxin that causes illness in humans.

New AI models quickly find compounds that target Lyme bacteria

Tufts University researchers are using AI and machine learning to more quickly identify potential narrow-spectrum antibiotics to prevent and treat Lyme disease, thanks to a generous gift from an alumnus that sped up their timeline by two to three years.

How DNA and life experiences leave distinct marks on the human immune system

Using single-cell epigenomic profiling of immune cells from 110 individuals, researchers show that genetic variation and environmental exposures shape the human immune system through distinct DNA methylation mechanisms. Genetic effects concentrate within gene bodies of memory cells, while environmental exposures primarily remodel regulatory regions in naive immune cells.
