Satureja Bachtiarica

Streptococcus iniae is among the major pathogens of a large number of fish species cultured in fresh and marine recirculating and net pen production systems. Ten Iranian medicinal plants were assessed for their antimicrobial activity against Streptococcus iniae isolates obtained from diseased Oncorhynchus mykiss (Salmonidae; Walbaum, 1972) collected from fish farms in Iran. The antibacterial activity of ethanol extracts of Punica granatum, Quercus branti, Glycyrrhiza glabra and essential oils of Heracleum lasiopetalum, Satureja bachtiarica, Thymus daenensis, Myrtus communis, Echinophora platyloba, Kelussia odoratissima and Stachys lavandulifolia against Steptococcus iniae was evaluated by disc diffusion and serial dilution assays. Most of the extracts and essential oils showed a relatively high antibacterial activity against Streptococcus iniae. Of the plants studied, the most active extracts were those obtained from the essential oils of Satureja bachtiarica, Echinophora platyloba, Thymus daenensis and the ethanol extract of Quercus branti. Some of the extracts were active against Streptococcus iniae. Two essential oils showed lower MIC values; Heracleum lasiopetalum (78 ?g/ml) and Satureja bachtiarica (39 ?g/ml). The essential oil of Satureja bachtiarica could be an important source of antibacterial compounds against the Streptococcus iniae isolated from rainbow trout.

Multiresistant Strains

In infectiology, some essential oils (EOs) are able to competewith antibiotic therapy and even surpass it; it is in this context that a study of the chemical composition and the antibacterial power of the EOs of three aromatic and widely used medicinal plants in traditional medicine was conducted which are Satureja calamintha subsp. nepeta (L.) Briq, Lavandula multifida L., and Mentha pulegium L. The extracted EO yields were of the order of 2.6%, 0.12%, and 5.29% for Satureja calamintha, Lavandula multifida, and Mentha pulegium, respectively. The obtained EOs were analyzed by gas chromatography coupled with mass spectrometry (GC/MS). The results of these analyses showed that Lavandula multifida contains carvacrol as a majority compound (70.65%); by contrast, the pulegone is the majority compound of Satureja calamintha and Mentha pulegium that contain about 87.04% and 71.97%, respectively. The EOs with the pulegone as predominant compound (Mentha pulegium and Satureja calamintha) showed higher antibacterial activity when tested against some multiresistant strains, compared to those with the carvacrol as major compound. In conclusion, this study may open up prospects for the formulation of phytomedicines against resistant and nonresistant bacteria incriminated in nosocomial infections.
