| Mucormycosis usually presents as a progressive infection with significant angio-invasion. Mucormycosis due to Mucor irregularis (formerly Rhizomucor variabilis var. variabilis), however, is exceptional in causing chronic cutaneous infection in immunocompetent humans, ultimately leading to severe morbidity if left untreated. More than 90 % of the cases known to date were reported from Asia, mainly from China. The nearest neighbour of M. irregularis is the saprobic species M. hiemalis. The aim of this study was to evaluate the taxonomic position, epidemiology, and intra- and inter-species diversity of M. irregularis based on 21 strains (clinical n = 17) by multilocus analysis using ITS, LSU, RPB1 and RPB2 genes, compared to results of cluster analysis with... |

| The automated Bioscreen C system was used for growth of four Mucor hiemalis strains isolated from the soil in the Juréia-Itatins Ecology Station (JIES), São Paulo state, in liquid culture media containing different carbon (2%) and nitrogen (1%) sources, pH 5.0, at 25ºC, and agitated at 150 rpm for 5 days. The medium containing only one nitrogen source had been added with 2% glucose. The readings were taken at lambda = 540 nm, at 2-hour intervals, up to five days. The results were compared using the Friedman Test (alpha = 5%). The best growth was obtained for strains M1, M2 and M3, reaching the log phase in 60 hours. The best carbon sources varied according to the strain, and yeast extract proved to be the best nitrogen source. Sodium acetate inhibited the... |
