چکیده
UNLABELLED Acute Otitis Externa is an inflammation of the outer auditory meatus, and according to popular saying, medicinal plant extracts can be used in its treatment. AIM to assess the in vitro antimicrobial activity of the following plants: Aleolanthus suaveolens; Caryophyllus aromaticus; Cymbopogon citratus; Matricaria chamomila; Pithecellobium avaremotemo; Plectranthus amboinicus and Ruta graveolens on the germs that cause otitis externa. MATERIALS AND METHODS the minimum inhibitory concentration of extracts and oils from these plants was obtained from otitis externa samples. RESULTS Staphylococcus aureus in 10 cultures, Pseudomonas aeruginosa in 8, Pseudomonas aeruginosa and Staphylococcus aureus together in 5 cultures and Candida albicans and Candida krusei in 4 cultures. P. aeruginosa was resistant to all oils and extracts tested; extracts from A. suaveolens, P. avaremotemo and R. graveolens were inactive; the essential oil from C. aromaticus and M. chamomila were active against 3 strains of S. aureus and the Candida strains; seven of the S. aureus strains were sensitive to the P. amboinicus extract; however, the oil was inactive against 4 S. aureus strains and the Candida strains were sensitive to the R. graveolens essential oil. CONCLUSION depending on the etiological agent, some plants presented satisfactory results, however we still need more detailed studies in order to better use these plants.
