Answer :
Answer: Gene therapies
Explanation:
The resistance problem to antibiotic X is caused by the evolution and transfer of genes that confer resistance to antibiotic X into bacteria Y. The acquisition of such resistance genes by bacteria Y complicates disease treatment, hence the need to seek alternatives.
The course of treatment that would most likely help a patient suffering from a disease caused by the newly developed strain of bacteria Y described in the question is gene therapy. Gene therapy aims to enhance the response of the immune system to infection. Another alternative is to use bacteriophage antibiotics to provide antimicrobial defenses and support.
