An elderly femаle pаtient hаd been admitted fоr a hip replacement. The patient seemed tо be recоvering well until she developed redness, increased swelling, and purulent discharge at the surgical site. The wound was cultured and results from microbiological testing revealed that the infection was caused by Staphylococcus aureus. The patient successfully completed the course of antibiotic therapy, and within a few days, all signs of infection had subsided. The patient was progressing well with physiotherapy, and was planning for discharge when the patient suddenly began to experience diarrhea. On the first day, the patient had two loose bowel movements. By the second day, the episodes of diarrhea were occurring every 2 to 3 hours. The stools were watery and foul-smelling and contained large amounts of mucus. The patient complained of mild abdominal pain and cramping, and she subsequently developed a fever. The physician was notified, and a stool specimen was collected for laboratory testing. The stool culture came back showing that the patient’s diarrhea was actually caused by the Clostridium difficile. The patient was placed on contact isolation and was started on intravenous metronidazole (Flagyl). With this treatment, the diarrhea gradually slowed and finally stopped. Repeat cultures performed after the metronidazole therapy was completed showed that the infection had been successfully cleared. QUESTION: What are risk factors for this patient to develop Clostridium difficile infection (2.5 points)? Also give the Domain and type of microorganism C. diff is (2.5 points).
