- Q. Because you love to work with children, you accept a job offer at a local pediatric clinic. A concerned mother brings herdaughter who had eye infection (pink eye, caused by gram-negative bacteria). The doctor prescribes her Cephalosporinantimicrobial drug. After a few days, the mother returned to the clinic and complained that the medicine did not help herdaughter. This time, the physician prescribes Penicillin antimicrobial drugs. However, based on your knowledge inmicrobiology class answer:1) why Cephalosporins does not eliminate the bacteria? 2) why do you think the Penicillin antimicrobial drugs will not help the little girl, and the physician should prescribe aStreptomycin antimicrobial drug as eye drops? 3) If the same bacteria develop resistance to Streptomycin, describe the bacteria's possible resistance method against thisantimicrobial drug?arrow_forwardDoctors prescribe synergistic drug combinations to treatbacterial infections.
