Preliminary studies on activity of Ocimum sanctum, Drynaria quercifolia, and Annona squamosa against Neisseria gonorrhoeae.

BACKGROUND

Despite the progressive increase of antimicrobial resistance of Neisseria gonorrhoeae worldwide, there are limited reports of alternative remedies from plants.

GOAL: The aim of the current study was to screen 3 plants, Ocimum sanctum, Drynaria quercifolia, and Annona squamosa, for activity against Neisseria gonorrhoeae.

STUDY: By disc diffusion method, extracts of these 3 plants were screened for activity against Neisseria gonorrhoeae; their antimicrobial activity was calculated as percentage inhibition and compared with penicillin and ciprofloxacin.

RESULTS

The extracts of all 3 plants caused inhibition of Neisseria gonorrhoeae clinical isolates and World Health Organization (WHO) strains, more so than the multidrug resistant Neisseria gonorrhoeae.

CONCLUSION

Neisseria gonorrhoeae clinical isolates and WHO strains were sensitive to extracts of Ocimum sanctum, Drynaria quercifolia, and Annona squamosa. This motivates us to isolate the active component/second from the 3 plants.
