Abstract
Many bacterial and fungal strains are involved in wound infectious diseases as most of these strains become resistant to the most commonly used synthetic drugs in Himalayan region. Plant based natural products seem to be an alternative to this problem. The aim of this investigation was to evaluate the In vitro antibacterial and antifungal activities of 30 medicinal plants used in folk recipes by Himalayan people to treat wound infections against multi-drug resistant pathogens. In total of six medically important Myco-bacterial strains Streptococcus pyogenes, Staphylococcus aureus, Klebsiella pneumoniae, Pseudomonas aeruginosa, Candida albicans and Aspergillus niger were tested against methanolic plant extracts at 5 mg/ml concentration using agar disc well diffusion method to determined Minimum inhibitory concentrations (MICs).The plant extracts showed varied levels of MICs against test microorganisms. The strongest antibacterial activity was reported in methanolic extract of Cynadon dactylon (L.) Pers. against Klebsiella pneumoniae with 20.67±1.36 mm MICs, while Candida albicans was considered to be the most resistant pathogen with MICs9.6±0.57 mm. The findings were compared with results obtained using standard antibiotics, amoxicillin, ciprofloxacin, cefotaxime, fluconazole and itraconazole at conc.5mg/ ml. The results provide an evidence of folk medicinal uses of plants among the Himalayan communities to treat wounds. Further research needs to be carried out to identify the active molecules and evaluate the in vivo antibacterial and antifungal activities as well as toxicity level with clinical trials to use full potential of these plants for drug discovery development to control wounds globally.
