Beschreibungen/Notizen

• The oil, aqueous infusion and decoction of oregano (Origanum vulgare), of the family Limiaceae, were assessed for antibacterial activity against 11 different genera of Gram-ve bacilli viz., Aeromonas hydrophila, Citrobacter sp., Enterobacter aerogenese, Escherichia coli, Flavobacterium sp., Klebsiella ozaenae, K. pneumoniae, Proteus mirabilis, Pseudomonas aeruginosa, Salmonella typhi, S. paratyphi B, Serratia marcescens and Shigella dysenteriae, by disc diffusion method. Oregano oil exhibited the highest activity against Citrobacter species with mean zone of inhibition of 24.0 mm plus minus 0.5. The aqueous infusion also showed significant inhibitory activity against Klebsiella pneumoniae (20.1 mm plus minus 6.1 SD), Klebsiella ozaenae (19.5 mm plus minus 0.5 SD) and Enterobacter aerogenes (18.0 mm). Besides, all isolates were found resistant to the aqueous decoction of oregano seeds.
