Question: What are superbugs?


  1. A superbug is a strain of bacteria that is resistant to more than 3 types of prescribed antibiotics.

    the most common are MRSA (methicilin resistant staphylococcus aureus), pseudomonas aeruginosa, and streptococcus pneumoniae.

    normal bacteria turn into “super” bugs when they are exposed to antibiotics a lot. when this happens it can turn on genes to make more pumps to get rid of the drugs. it can also mutate so other pumps can get the drug out of the cell. Because bacteria can divide as fast as every 20 minutes, they have a much faster mutation rate than humans. ie they can evolve super fast into superbugs!



  1. a super bug must be really scary


  2. trainmain, they can be very scary to the people who catch them, and for the doctors trying to treat them
