Question
A scientist tested three antibiotics on the growth of Staphylococcus aureus, a bacterium that causes infections in humans.These are their results:The scientist concluded that cloxacillin is the best antibiotic to use for all bacterial infections.Why might the scientist's conclusion be wrong?Choose a reason from the options below.Even at the lowest concentration, cloxacillin killed the most bacteria.Kanamycin has the smallest clear zone, despite being at the highest concentration.They only tested the antibiotics on Staphylococcus aureus.Cloxacillin has the largest clear zone.
Solution
The scientist's conclusion might be wrong because they only tested the antibiotics on Staphylococcus aureus. This means that while cloxacillin may be effective against this particular type of bacteria, it may not be as effective or could even be ineffective against other types of bacteria. Therefore, it would be incorrect to conclude that it is the best antibiotic for all bacterial infections based solely on this experiment.

Which of the following statements is true concerning Alexander Fleming and his antimicrobial discovery? View Available Hint(s)for Part A Immediately following its discovery, the first antibiotic was mass produced and made readily available to the public. The first antibiotic was discovered by accident when a contaminating mold killed a culture of Staphylococcus aureus. Alexander Fleming discovered the first antibiotic, bacitracin, made by the bacterium Bacillus. Alexander Fleming sought an antimicrobial compound that could be used as an alternative to amputation in patients who suffered from gas gangrene caused by Clostridium perfringens.
