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.

Study points to a possible new approach for treating MRSA superbug

A study released in STEM CELLS Translational Medicine, by researchers at the Baker Institute for Animal Health, part of Cornell University's College of Veterinary Medicine, Ithaca, N.Y., details in a relevant ex vivo model how treating wounds with the secretion of a type of stem cell called mesenchymal stromal cell (MSC) effectively reduced methicillin-resistant Staphylococcus aureus – better known as MRSA viability and stimulated the surrounding skin cells to build up a defense against the bacterial invader.

Boeing tested air purifiers like those widely used in schools. It decided not to use them in planes.

Aerospace giant Boeing tested two kinds of ionization technologies — like those widely adopted in schools hoping to combat covid — to determine how well each killed germs on surfaces and decided that neither was effective enough to install on its commercial planes.
