Describe three main mechanisms antibiotic resistance.
|
a. Inherit the genes from their forerunners
b. Genetic mutation will spontaneously produce resistance or strengthen existing resistance c. Bacteria will gain a defense against an antibiotic by taking up resistance genes from other bacterial cells in the vicinity |
|
|
How do bacteria acquire the “resistance genes” needed to carry out one or more of the mechanisms described above?
|
a. One bacterium will pass resistance trait to others by giving them a useful plasmid that contains resistant DNA
b. When a bacterium dies another bacterium can take up its contact c. Can also be extracted from one bacterial cell and injected into another. d. Bacteria contain specialized transposons called integrons. Integrons can consist of several different resistance genes which are passed to other bacteria. These genes provide the bacteria with resistance. |
|
|
How does the use of antibiotics (especially broad spectrum) promote resistance?
|
a. It kills healthy “non-viral” and viral bacterium which then reduces the competition of the resistant bacterium cells, allowing them faster proliferation and making them even harder to kill.
|
|
|
Why are antibiotic susceptible bacteria actually more likely to “outcompete” resistant bacteria when antibiotic drugs are stopped?
|
a. Because they are not being killed by the antibiotic, which forces the resistant bacteria to divert some of their energy from reproduction to maintaining antibiotic-fighting traits.
|
|
|
Review the recommended actions of physicians and consumers to limit resistance (on the last page of the article.) Can you think of specific nursing actions that should be added to that list?
|
a. Encourage patients to wash hands and take their full course of antibiotics
b. Educated patients on the importance of taking antibiotics only when needed c. Suggest alternatives to constantly using antibacterial products d. Suggest ways to stay healthy and keep up good bacterial flora. |
