Antibiotics P1, P2 (cell wall synthesis inhibitors), and Q1, Q2 (protein synthesis inhibitors) are equally hydrophilic and moderately toxic to humans. Staphylococcus is known to develop resistance to all these antibiotics. An experimenter tested these antibiotics against a recent pathogenic strain of Bacillus. A high density of Bacillus culture was spread on a nutrient agar plate. Filter paper discs, each soaked in P

Options

  1. AQ2 would be the preferred antibiotic for therapy against this Bacillus infection.
  2. BIf P 2 is a new generation antibiotic derived from P 1 , then long term use of P 2 is likely to remain highly
  3. CThe combination of P1 and P2 will not lead to antibiotic resistance in the Bacillus.
  4. DThe combination of P1 and Q2 is least likely to lead to antibiotic resistance in the Bacillus.

Correct answer

D. The combination of P1 and Q2 is least likely to lead to antibiotic resistance in the Bacillus.
