Q. Because you love to work with children, you accept a job offer at a local pediatric clinic. A concerned mother brings her daughter who had eye infection (pink eye, caused by gram-negative bacteria). The doctor prescribes her Cephalosporin antimicrobial drug. After a few days, the mother returned to the clinic and complained that the medicine did not help her daughter. This time, the physician prescribes Penicillin antimicrobial drugs. However, based on your knowledge in microbiology 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 a Streptomycin antimicrobial drug as eye drops?  3) If the same bacteria develop resistance to Streptomycin, describe the bacteria's possible resistance method against this antimicrobial drug?

Reproductive system infection

The biological process through which parents produce new children is called reproduction. A reproductive system is a group of internal and external organs that collaborate to allow males and females to reproduce. Many experts believe that the reproductive system is one of the most important systems in the body due to its crucial function in the survival of the species. Among the body's basic systems, the reproductive tract is the one that differs the most between sexes, and it is also the only one that does not operate until puberty.
