- Clinical application: A 44-year-old man with HIV is receiving antibiotics through a intravenous catheter. The antibiotics are to help treat a kidney infection. The patient develops a fever. Subsequent cultures from the patient's blood, the needle tip, and from the insertion site all show growth of an organism with large oval-shaped cells. The cells reproduce by budding.
