Abstract

The ethanol extracts obtained from the leaves of Stachys sylvatica L. (Lamiaceae) were evaluated for their antibacterial activity against some human eye pathogens by disc diffusion method against hospital isolates of Bacillus cereus, Pseudomonas aeruginosa, Klebsiella pneumoniae, Staphylococcus capitis, Staphylococcus aureus, Staphylococcus epidermidis, Moraxella nonliquefaciens and Cutibacterium acnes. Besides, Penicillin, Ampicillin and Tobramycin as antibacterial antibiotics were used as a positive reference standard to determine the sensitivity of the isolates. The extracts showed a potential antibacterial effect against Staphylococcus capitis, Moraxella nonliquefaciens and Cutibacterium acnes, with inhibition zones of 22.4 mm, 21.6 mm and 20.2 mm, respectively. The extracts also exhibited a moderate effect against the other bacterial isolates. The plant may be useful in the treatment of eye infections.
