Question

tuberculosis is a bacterial infection that can be treated with antibiotics. in some regions, individuals with tuberculosis had one antibiotic treatment but were unable to have the necessary follow up antibiotic treatments. this led to the development of much more deadly strains of tuberculosis. this is a case of ______.

a antibiotic resistance

b antibiotic strength

c bacterial shortage

d none of the above

Explanation:

Antibiotic resistance occurs when bacteria evolve to withstand the effects of antibiotics. In this case, incomplete antibiotic treatment allowed tuberculosis bacteria to survive and develop strains resistant to the antibiotic, matching option a. Option b (antibiotic strength) refers to the potency of the drug, not the bacteria's adaptation. Option c (bacterial shortage) is incorrect as the issue is about bacteria evolving resistance, not a lack of bacteria.

Answer:

a. antibiotic resistance
