Although studies on the chemistry of odors are expanding to identify the chemical structures of odorous substances, there are no universal standards as yet to measure odor and intensity of bromidrosis. Clinical evaluation can be made on a subjective scoring from 0 to 3 prior to prescription of an antiseptic soap. In order to appreciate the correlation between the intensity of bromidrosis (BI) and bacterial activity, a study was carried out with both clinical and bacterial assessment in thirty patients with axillary or plantar BI. Odor intensity was evaluated by two physicians using a score from 0 to 3 (i.e. absent, minor, moderate, major), meanwhile bacterial composition and density were assessed before and after 10 days of hygiene using an antiseptic detergent (trichlocarbanilide) provided on the first visit. Baseline count of diphtheroids/cm2 was 35.104 and baseline micrococci average was 32.104/cm2. At the end of the study, the reduction of odor intensity was observed in 20 patients (67%) without any change in sweat production. The clinical improvement correlated with a reduction of both micrococci (70%) or diphtheroids (73%) as compared with initial data. In patients presenting persistant bromidrosis, the bacterial count/cm2 did not significantly decrease and remained above 104 diphtheroids/cm2. Thus, this study suggests that body odor may be at least indirectly correlated to microbia counts with a bacteria threshold of BI ranging around and above 104.
