00:01 All right, so to answer this question, i'm just going to go through our provided answer choices and kind of just talk through them.

00:07 I think that would be the easiest way to kind of go about combating this question.

00:11 So in looking at strategies to help reduce the risk of developing antibiotic resistance, looking at letter a, using antibiotics only one appropriate.

00:23 This is true.

00:25 It very well indeed does reduce the risk of antibiotic resistance.

00:31 Lately, antibiotics have been prescribed more and more often, and it's this increased usage that is allowing these bacteria to mutate, giving them more chances to mutate, allowing them to become stronger and stronger.

00:46 So it's important to only use them when medically deemed necessary.

00:51 A really important implication in this is not using them to treat viral infections.

00:58 Obviously, an antibiotic is going to treat a bacterial infection, but it is not going to treat or benefit a viral infection.

01:07 So this is just one example of using antibiotics inappropriately that is directly leading to this antibiotic resistance when we could prevent it.

01:18 Letter d, using the drugs as directed, and this is true.

01:22 It's very important, especially in taking the full course of the antibiotic.

01:30 A lot of the times were prescribed, you know, like a two -week course of an antibiotic.

01:34 If you take a few days, you start to feel better.

01:37 So you stop taking the antibiotic.

01:39 But in this case, all you have done is you've given the antibiotic a chance to kill off the weak bacteria, but the strongest bacteria or maybe the bacteria that are a little bit mutated still exist.

01:51 So these bacteria are still able to reproduce, mutate, the infection is going to continue.

02:00 Letter c, using more than one antibiotic at a time for difficult to treat organisms...
