Microscopic analysis of candidiasis on the tongue dorsum of mice. Scores obtained from optical microscopy of histological sections stained by PAS after 24 h of the treatment with essential oil of M. alternifolia or physiological solution for the control group (n = 10 per group). Scores were attributed according to Junqueira et al. 2005: Score 1 (1 to 5 yeasts/hyphae), Score 2 (6 to 15 yeasts/hyphae), Score 3 (16 to 50 yeasts/hyphae), and Score 4 (more than 50 yeasts/hyphae). There were no significant differences between the groups treated with M. alternifolia oil and control (Mann-Whitney test, P = 0.2596).
