(Extra Credit: 5 Points): A bacterial cell of the species Calhounia oropharyngius is attached to the mucosal membrane lining of the oropharynx in a patient, where it resides normally as part of the harmless microbiome under normal conditions. The cell attaches with fimbriae protein spikes on its surface. The patient is being treated for a cancerous tumor in the oral cavity and receives gamma-irradiation therapy to kill the cancer cells. Following one of the treatments, the bacterial cell divides, and one of its daughter cells now has fimbriae proteins that attach to the mucosal membrane lining of the lower respiratory tract, deep in the lungs (as well as to the original location in the oropharynx). As this daughter cell with the new trait divides, a large population of cells adheres in the lungs, and the patient develops severe pneumonia. Explain what you think happened in this scenario. Your answer should explain how the bacterial cell’s exposure to gamma-irradiation led to changes in fimbriae protein spikes on the surface. Your explanation should be based on the genetic processes we studied in the unit. Finally, state whether you think this scenario is an example of natural selection, and defend your answer. View the scoring rubric for this question, and be sure to include all details.
