Researchers from the University of Tsukuba show that antibiotic resistance can be transferred between Staphylococcus bacteria by a process known as natural transformation … A bacteria called Staphylococcus aureus is widespread and generally harmless, but can cause infections known as “opportunistic infections”. These occur when the bacteria take advantage of certain situations, such as a weakened immune system or the presence of an open wound, to cause a harmful infection. These infections become particularly dangerous when the bacterial strain is resistant to treatment with antibiotics. Strains of Staphylococcus aureus known as MRSA, which are resistant to an antibiotic called methicillin, are becoming a significant problem worldwide. Now, a team from the University of Tsukuba have revealed the mechanism by which this methicillin resistance can be passed between bacteria … read more
