What superbugs are there?By Guy Tsafnat - July 20, 2015, 4 PM
“Superbug” is a nickname given to infections for which there are no antibiotics because they can resist any antibiotic we have to fight them. Usually, this is because the bacteria are resistant to the antibiotic drug. Bacteria resist antibiotics in a variety of forms such as having walls that don’t allow the drug into them and producing enzymes that break down the drug before it can damage them. To do that, the bacteria need to have specific genes. Sometimes, combinations of genes make the bacteria resistant to more than one antibiotic and even all known ones. MRSA (AKA “golden staph”) is a common example. Usually this infection is acquired in a hospital and especially in intensive care units. It is the oldest and most widely spread superbug of the species staphylococcus aureus.
