    Abstract

    The axillary microflora of 34 male subjects were studied in relation to their underarm odour intensity. The predominant groups of micro-organisms were aerobic coryneforms, Micrococcaceae and propionibacteria. There was no competition for habitat between these groups (Fisher's exact test P greater than 0.05). There was an association between the population density of aerobic coryneforms and the intensity of odour (Spearman, P = 0.001). Dominance of aerobic coryneforms within the axillary microflora was associated with high odour intensity (chi 2, P = 0.005). An in-vitro odour model was developed using a diethyl ether extract of axillary skin incubated with test bacteria. Underarm odour was produced exclusively by aerobic coryneform bacteria. Of aerobic coryneforms, 71.4% were odour producers and these were identified as Corynebacterium xerosis.
