This seems to have progressed over the past day and is accompanied by increased urge and frequency. The emergency room physician obtains a urinalysis which demonstrates the following: SG: 1.010, Leukocyte esterase: Positive, Protein: Trace, pH: 7.5, RBC: Negative. Nitrite: Negative. A urease test is performed which is positive. What is most likely cause of UTI in this patient?
