RESUMO
ãMalodorants in the human axilla are produced from human biogenic precursors by axillary bacterial enzymes. In the present study, we used pyrosequencing analysis to identify the axillary bacterial microbiota of 13 Japanese male subjects with cumin-like, spicy body odor (C type), and 9 with milky, skin-based body odor (M type). Anaerococcus, Corynebacterium, and Staphylococcus predominated in both C- and M-type subjects, followed by Moraxella and Peptoniphilus. These genera accounted for 96.2-99.9% of the total bacterial population, except in the microbiota of one C-type subject. However, the axillary bacteria in C-type subjects were more abundant than that in M-type subjects. These results suggest that the level of colonization by axillary bacteria is important for the production of malodorants.
