- hospital bug
Bacterial pathogen that is resistant to many common antibiotics. These types of germs increasingly spread in hospitals, where a lot of antibiotics are prescribed, and patients with a weakened immune system are particularly at risk. One much-feared example are MRSA's, the methicillin-resistant strains of Staphylococcus aureus. Only one of a handful of reserve antibiotics that may only be prescribed in rare exceptions will help with this bacterium.
