Abstract-Aromatic and medicinal plants are an important source of antimicrobial molecules, especially in volatile extracts. The genus Thymus is considered among the richest in essential oils. In this context, this work focuses on the extraction of the organic compound by steam soxlhet of a species endemic; Thymus numidicus L. from Bouira. On the other hand, the determination of the antimicrobial activity of this organic compound. In this study, we have used these microorganisms; Echerichia coli, Pseudomonas fluorescence, Staphylococcus aureus, Aspergillus fumigatus, Candida albicans, and Aspergillus niger. The antimicrobial activity was tested by agar diffusion technique and calculation of the minimum inhibitory concentrations (MICS). The results showed a very good antimicrobial activity on the bacteria and no effect on yeasts and molds tested.

The increase in antibiotic resistance has resulted in decreasing number active antimicrobial agents available to treat infections by multi-drug resistant (MDR) bacteria. The aim of this study was to determine the antimicrobial activity of the extracts of Glaucium elegans and Saffron (Crocus sativus) onios plant species against Escherichia coli, Staphylococcus aureus, Salmonella enteritidis, Bacillus anthracis and Proteus by disc diffusion method. The methanol extract of G. elegans was found to have a significant antibacterial efficiency (p≤0.05) as compared to the methanol extract of onios plant. These finding pinpoint the efficiency of these extracts to inhibit microbial growth. The bactericidal activity described here represents an added safety value for G. elegans possesses the significant antibacterial activity. Article Info

“…In the case of MBC, all the isolates except one P. mirabilis strain showed MBC/ MIC values of ≤ 2 demonstrating the bactericidal effect of cinnamon oil. Generally, an agent can be considered bactericidal when the MBC/MIC ratio is < 4 and bacteriostatic when it is > 4 ( Kone et al 2004). The MIC and MBC profile of clove oil was observed to be similar to cinnamon oil with the exception of P. aeruginosa.…”

Essential oils are plant extracts that have been used for their antimicrobial properties for centuries. The keeping of turtles as pets exhibits a growing trend worldwide but these animals are known to harbour a range of pathogenic bacteria. In the current study, we assessed eight essential oils as alternative antibacterial agents against nine species of pet turtle-borne Gram-negative bacteria, namely Aeromonas caviae, A. dhakensis, A. hydrophila, Citrobacter freundii, Morganella morganii, Proteus mirabilis, P. vulgaris, Pseudomonas aeruginosa and Salmonella enterica. Except for Pseudomonas aeruginosa, all other bacterial species showed high susceptibility to six essential oils, namely oregano, cinnamon, clove, lemongrass, lavender and eucalyptus oils in descending order of efficacy. Minimum inhibitory concentrations and minimum bactericidal concentrations values of the essential oils against all tested species except for P. aeruginosa showed low heterogeneity, showing that these essential oils can effectively control the growth of nearly all the tested. However, most of the tested bacteria were multiple-antibiotic-resistant as determined in the antibiotic disc diffusion test, with multiple-antibiotic-resistant index values of ≥ 0.2 for most of the strains. Therefore, with regards to their in vitro activity in controlling growth of multi-drug resistant bacteria, we can classify oregano, cinnamon, clove, lemongrass, lavender and eucalyptus essential oils as effective antibacterial agents. Thus, prospective application of these essential oils in controlling and treating these bacteria should be considered.
