FIGURE 2.

Swabs were collected from genitals and their surrounding skin surfaces in patients with and without incontinence‐associated dermatitis. A, The photos show an example of the urea medium after bacterial cultivation. To determine the urease activity in each swab, three classification strata (strong, weak, and almost none/none) were determined by the degree of colour change in the agar medium from yellow to red. B, The urease activity based on the three classification strata was compared between two groups.
