 The malodour generation of a persons armpit is caused by the bacteria thriving on that armpit. In order to alter or reduce once bad body odour, the living microbial community on the armpit of a non-malodorous person will be transmitted or up scaled and transmitted to the armpit of a malodorous person. The odour is evaluated by a trained smelling panel, the bacteria living on the armpit is examined by means of molecular techniques. The microbial transplantation and its follow-up happens under the supervision of a medical doctor.
