A 70-year-old woman presented with chronic ulcerative nodules on her lower extremities at the outpatient clinic. A tender red nodule developed on her left anterior tibial region a month ago, which gradually enlarged; spontaneous ulceration of the nodule and occasional pain were reported. The lesions did not respond to topical antibiotics, and more nodular lesions appeared in the mid-calf area (Figure 1) and spread to her toes. Her medical history included kidney transplantation 6 years ago and chronic tinea pedis. 1.1 What disease is this woman affected by? (2 points) 1.2 What is this pathogen feeding on? (2 points) 1.3 What is the treatment for this infection? (2 points)

A 65-year old woman has been hospitalized for 3 weeks for chronic obstructive pulmonary disease (COPD) when she develops lung pain and exacerbation of her shortness of breath.

A 45-year-old woman is admitted to the hospital with an unremitting sore throat. She has undergone radical mastectomy for breast carcinoma and recently underwent adjuvant chemotherapy. Two weeks before, she received a seven-day course of amoxicillin-clavulanic acid (Augmentin) for a recurrent urinary tract infection. Examination of her palate reveals several patches of white, creamy, curd-like lesions on the tongue and other mucosal surfaces. What is the most likely infection this patient has? Which of the following may be used to treat the patient? Ketoconazole, Fluconazole, Nystatin, Clotrimazole, or All of the above.
