“…Reports have shown that essential oils having eugenol, carvacrol and thymol (phenolic compounds) had maximum antibacterial performances and T. vulgaris have been identified to contain thymol (Ismail et al 2012). This is not surprising as the antimicrobial nature of many edible plant extracts have been demonstrated (Benbelaïd et al 2013;Radulovic et al 2013). Nzeako et al (2006) had earlier reported on antimicrobial activity of T. vulgaris against Pseudomonas aeruginosa, Salmonella spp and Staphylococcus aureus at various dilutions.…”

This study examined the antibacterial activity of Thymus vulgaris on multiple antibiotic resistant (MAR) Vibrio parahaemolyticus and Vibrio fluvialis isolated from shrimps. The ethanol extract of T. vulgaris antibacterial properties was assessed using the agar diffusion method. Survival of test organisms in shrimp meat using different concentrations of T. vulgaris was done using standard method. The quantitative and qualitative phytochemical tests of T. vulgaris extract were determined. The ethanol extract had antimicrobial activities on the test organisms showing 20.00 ± 0.0 and 23.00 ± 0.0 mm zone of inhibition on V. parahaemolyticus and V. fluvialis respectively. T. vulgaris completely decreased microbial load of V. parahaemolyticus and V. fluvialis in 150 and 60 min, respectively. The phytochemical screening for the ethanol extract reported phenol, alkaloids, tannin, saponin, anthraquinone flavonoid and cardiac glycoside as 51. 76, 26.60, 6.76, 54.33, 30.35 89.65 and 18.23 mg/100 g, respectively. This study reveals the antibacterial property of T. vulgaris on the MAR Vibrio species.

Medicinal plants constitute natural source of antimicrobial drugs that will provide essential compounds to fight against disease. In this study, the antibacterial activity of ethanol extracts of Moringa stenopetala, Thymus serrulatus, and Terminalia brownii were investigated against selected pathogenic Gram positive and Gram negative bacteria. In vitro antibacterial activities of the ethanol extracts were tested at a concentration of 50, 25, and 12.5 mg/ml by using agar disc diffusion method and zone of inhibitions were determined. Furthermore, minimum inhibitory concentrations were determined for plants that showed antibacterial activity (>15 mm zone of inhibition). The results indicated that only T. serrulatus and T. brownii exhibited antimicrobial activity against one or more test pathogens. Both extracts of these plants showed strong and dose dependent activity when compared with M. stenopetala which demonstrated no activity. Interestingly, T. serrulatus showed broad spectrum activity against the tested bacteria. Therefore, ethanol extracts of T. serrulatus and T. brownii showed promising antimicrobial activity justifying their usage in traditional medicine.

“…Preliminary evaluation of the antimicrobial activity was carried out by modified Kirby-Bauer's agar method [17,34]. In Petri dishes casted by solid medium, Mueller-Hinton agar (Fluka®, India) for bacteria or Sabouraud agar (Fluka®, India) for yeasts, and preinoculated by swabbing of standardized microbial suspension (10 8 CFU/mL), Whatman filter paper discs (6 mm diameters) impregnated with 10 µL of extracts were placed on the surface of agar.…”

“…For essential oil [34] [17], 10 initial concentrations were prepared similarly, excepting for the concentration fork was started from 80.00 to 0.15 (mg/mL), and we have used dimethyl sulfoxide at 10% instead of Tween 80 as emulsifier. So, in a 96-well microplate, the 10 final concentrations were defined between 8.000 and 0.015 (mg/mL).…”

“…Against this serious problem, research for alternative antibiotics must be continued and all possible strategies should be explored [16]. Among the available solutions, plant secondary metabolites are promising and wealthy sources for new effective antimicrobials, which are without side effects [17], unlike most of presently used antibiotic.…”
