Antibiotic Resistance

Cards (6)

  • When bacteria evolve to become able to survive exposure to antibiotics, we say that they have developed: 
    Antibiotic resistance
  • Describe in detail how antibiotic resistance arises?
    A population of a bacteria infect somebody
    That person takes antibiotics to kill the bacteria
    Some bacteria have (or get) a random mutation that makes them less susceptible to the antibiotic than others (or completely resistant to it)
    The antibiotics kill all the bacteria except those that are resistant
    The resistance strains of bacteria now have more resources to grow and multiply 
    More mutations may arise, leading to greater resistance
  • To reduce the rise and spread of antibiotic resistance, should we increase or decrease the use of antibiotics?
    decrease use
  • Are antibiotics effective at treating viral diseases?
    no they treat bacteria
  • Give 3 reasons antibiotic resistance is becoming more common?
    Doctors often prescribe antibiotics in cases where they aren't necessary. For example, mild or viral infections
    Many people don't take the full course of antibiotics, so not all the bacteria are killed
    Huge amounts of antibiotics are given to farm animals in order to make them grow faster
  • Why is the spread of antibiotic resistance a problem?
    If more bacteria are resistant to antibiotics, we won't be able to treat those infections 
    This means more people will die of bacterial infections
