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 examine how superbug fights last-resort antibiotics

Antibiotic resistance is one of the biggest threats to global health, food security, and development today. A new study shows how superbugs adapt to combat 'last-resort antibiotics'.
