DB 3 – Biology: Antibiotic Resistance Antibiotic Resistance Part How Antibiotic Resistance Relate to Natural Selection Some bacteria are resistant to antibiotics. A good example is the Staphylococcus aureus resistance to antibiotic methicillin. Within a strain of bacteria, there are those that are weak and the antibiotic eliminates them with ease. Immunologically stronger bacteria survive the exposure to antibiotics and subsequently transfer the resistance traits to their off springs (Gibson and Gibson, 2009).

Therefore, the generations of resistant bacteria continue though natural selection.Action of People that Lead to Antimicrobial Resistance One fundamental trend that promote antibiotic resistance is repeated use if the same drug. Medical practitioners should change the drug where minimal or no improvement is evident in a patient. This help to kill the bacteria resistant to the previous antibiotic. Improper use of a given antibiotics also contribute to resistance. Patients who stop medication after observing a slight improvement expose themselves to resistance from the diagnosed bacteria.

Therefore, doctors must ensure their patients complete the dosage of a given antibiotic. In instances where the uses of antibiotics are widespread, the pathogen in question is likely to develop resistance as they mutate (CDC, 2014). Violation of antibiotic use in the above ways triggers the bacteria to develop resistance in different ways. Part 2The one sure way to tackle antibiotic resistance is to use antibiotics smartly. Smart use of antibiotic entails avoiding compromise in the use of antibiotic for treatment.

There are personal interventions that one can take to avoid the spread of antibiotic resistant pathogens, key being avoiding exposure. The sign found in restrooms is important as far as antibiotic resistance is concerned. It contributes to the fight against antibiotic resistance. It significantly creates awareness.
