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 a unique technique to fight hospital-borne disease

A study team developed an early-stage therapy that sabotages the pump and restores antibiotic efficiency by disclosing the structure of a protein needed by bacteria to pump out antibiotics.

Accurate diagnosis of bacterial superinfection pneumonia could help avoid antibiotic overuse

Only 21 percent of patients with severe pneumonia caused by SARS-CoV-2 (the virus that causes COVID-19) have a documented bacterial superinfection at the time of intubation, resulting in potential overuse of antibiotics, according to new research published online in the American Thoracic Society's American Journal of Respiratory and Critical Care Medicine.
