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.

Researchers discover how infectious bacteria can produce genetic variants among siblings

A research team from the University of Tübingen and the German Center for Infection Research is investigating how pathogens influence the immune response of their host with genetic variation.
