Discovery of new way for bacteria to transfer toxic genes to unrelated bacterial species

In a laboratory experiment, the scientists from NYU School of Medicine discovered that Staphylococcus aureus, a notorious bacterium that causes toxic shock syndrome and many other types of infections and is the scourge of hospitals nationwide due to its growing antibiotic resistance, could co-opt viral parasites as secret pipelines for transferring toxin genes to vastly different bacterial species.

New report shows high Clostridium difficile infection rates in U.S. hospitals

Consumers Union called on hospitals today to take more aggressive steps to protect patients from Clostridium difficile (C.-diff.) infections in light of a new report showing that they are much more common than previous estimates had indicated. As the rate of hospital acquired C.-diff. infections has jumped in recent years, an increasing number of patients have developed antibiotic-resistant strains of the infection that are more difficult to treat and more deadly.
