Aims:
Skin burns remain a noteworthy general medical issue throughout the world, as it boosts a condition of immuno-suppression. The present research aimed to evaluate the efficacy of Syzygium aromaticum extracts, silver sulphadiazine
ointment, and different commercially available topical antibiotics against pathogenic bacteria, isolated from the skin of
burn patients.
Methodology and results:
A total of 124 clinical pus samples were collected from the skin of burn patients, admitted to
two different tertiary care burn units at Peshawar, Pakistan. From these pus samples, 6 bacterial isolates from burned
skin (Staphylococcus epidermidis, Streptococcus, Klebsiella, Enterobacter, Bacillus and Pseudomonas spp.) were
isolated, while 4 different bacterial isolates (Staphylococcus epidermidis, Staphylococcus aureus, Bacillus and
Streptococcus spp.) were isolated from unburned skin via conventional culturing techniques. Further, antibacterial
assays were performed to compare the efficacy of S. aromaticum extracts (methanolic and aqueous extract), silver
sulphadiazine ointment, and different commercially available antibiotics against tested bacteria. It was observed that
both methanolic and aqueous extracts of S. aromaticum were effective at all concentrations against all the tested
bacteria. In addition, all the tested antibiotics expressed substantial activity against most of the bacterial isolates. While
silver sulphadiazine ointment was observed to be less potent against isolated bacteria as compared to S. aromaticum
extracts.
Conclusion, significance and impact of study
It was concluded that both aqueous and methanolic extracts of S.
aromaticum were effective antimicrobial agents and could be used as an alternative to control bacterial infections of burn
patients. This study would help to distinguish the risk factors of bacterial pathogenicity in burn patients and would also
provide a guideline to utilize medicinal plants and their extracts to minimize the chances of antibiotic resistance
phenomenon in burn patients.
