The clean catch urine plated on cystine lactose electrolyte deficient agar showed the growth of single type of bacterial colonies in the concentration more than 105 cfu/mL after 24 hrs of aerobic incubation at 37 C (Figure 1). The colonies grown were around 2 to 3 mm in diameter, convex, nonlactose fermenting, round, glistening, and smooth and produced violet nondiffusible pigment (Figure 1).
