Antibacterial Evaluation of Deodorant X and Bacterial Identification of Axilla in Young Adult Males via Clinical Trials

---

ody odour is an undesirable trait caused by the presence of certain bacteria including
Staphylococcus spp. and Corynebacterium spp. interacting with specific components in sweat, in
which the bacteria produce malodorous volatile compounds. Deodorant is a personal hygiene
product that has the function to combat body odour by way of many mechanisms, one of which is
the inhibition of bacterial growth. The objective of this study is to evaluate the antibacterial
properties of deodorant X adult male subjects between the ages of 18-22, as well as identify what
bacteria may be responsible for body odour production, and whether or not the deodorant can
inhibit the growth of these bacteria. Methods used for the clinical trial included the swab sample
collection from pre-conditioned axillary areas, one of them control and the other treated, and for
the antibacterial study, the Miles and Misra method was used to obtain the CFU/mL values from
the control and treated axilla. Gram-staining of bacterial colonies grown on MSA agar were used to
select for Staphylococcus spp. Results demonstrate that the deodorant tested reduced bacterial
growth but results were not statistically significant. Furthermore, results of bacterial identification
revealed that Staphylococcus aureus, and other Staphylococcus species beside S. aureus such as S.
hominis and S. epidermidis were also part of the normal microflora of young adult male axilla.
Thus, results can conclude that though the antibacterial effect of the deodorant is not significant, it
did reduce bacterial growth, and certain bacteria identified were the species responsible for the
production of body odour.
