RÉSUMÉ

Antibacterial activity of Lingzhi or Reishi medicinal mushroom, Ganoderma lucidum, collected from Central India was evaluated against four bacterial pathogens. Ethyl alcohol and water extracts of fruit body powder were tested using the disc diffusion method against Staphylococcus aureus, Klebsiella pneumoniae, Bacillus cereus, and Pseudomonas aeruginosa. It was noted that the aqueous extract inhibited growth of pathogenic bacteria. The combined effect of fruit body extract with synthetic antibiotic discs was found to increase the activity significantly more than the antibiotics alone. The present study is an attempt to assess antibacterial activity of extracts of G. lucidum singly and in combination. The combination of G. lucidum with commercial antibiotics proves that it enhances antibacterial activity.
