(c) Suggest two treatments and two preventive measures for this infection. (d) Non-toxic strains of bacteria can acquire toxin genes from viral genome. Briefly describe the process during which the toxic genes from virus are incorporated into bacterial chromosome.

27. After experiencing recurrent bacterial infections, you diagnose your patient, Mrs. Watts, with non immune mediated neutropenia.
