Overnight exposure of Salmonella enterica serovar Typhimurium to sublethal amounts of Origanum vulgare essential oil (OV) and carvacrol (CAR) did not result in direct and cross-bacterial protection. Cells subcultured with increasing amounts of OV or CAR survived up to the MIC of either compound, revealing few significant changes in bacterial susceptibility.

Satureja wiedemanniana (Lallem.) Velen (Lamiaceae) is an endemic species of Turkey. Aerial parts of the plant collected from eleven different localities in Turkey were subjected to hydrodistillation to yield essential oils which were analysed by a GC/MS system. Carvacrol, thymol, p-cymene and gamma-terpinene were found as the main constituents. Antibacterial evaluation of the oils was also carr...

a 3 × 2 factorial experiment was conducted to investigate the effect of thymol + carvacrol (0, 100 and 200 mg/kg) on ileal microbial population and jejuna and ileal histomorphology of broilers fed carboxy methyl cellulose (cmc: 0 and 2%) containing diet. each of the 6 dietary treatments was replicated 5 times with 12 chicks each from 0 to 42 days of age. there was no interaction effect of cmc a...

We evaluated the ability of the natural, plant-derived acaricides nootkatone and carvacrol to suppress Ixodes scapularis Say and Amblyomma americanum (L.) (Acari: Ixodidae). Aqueous formulations of 1 and 5% nootkatone applied by backpack sprayer to the forest litter layer completely suppressed I. scapularis nymphs through 2 d. Thereafter, the level of reduction gradually declined to < or =50% a...

Effects of essential oil compounds (EOC) on feed intake, ruminal fermentation, growth performance, and carcass characteristics were determined using 60 lambs (24.6± 0.77 kg initial live weight, LW) fed either a barleyor corn grain-based diet without supplementation (control), or supplemented with 0.2 g/kg (DM basis) of carvacrol (CAR) or cinnamaldehyde (CIN). The experimental diets were arrange...

Aim: To evaluate the cardiovascular effect of carvacrol treatment in a D(+)galactose accelerated aging model, investigating effects on vascular reactivity, oxidative stress, and systolic blood pressure (SBP).&#x0D; Methodology: Eight-week-old male Wistar rats (Rattus norvegicus) were used for oral eight weeks. Organ baths reactivity studies (FEN, ACh, NPS), fluorescence microscopy to detect rea...

an experiment was conducted to study the effects of enzyme and phytogenic product (thymol+carvacrol) on the ileal microbial population and jejuna and ileal histomorphology of broilers fed wheat based diet. the experiment was conducted as a 2 × 3 factorial arrangement with 2 levels of enzyme endofeed w (0 and 0.05%) and 3 levels of next enhance 150® (0, 100 and 200 mg/kg). each of the 6 dietary ...

background & aim: the genus thymus belonging to the family of lamiaceae and consist over 215 different species throughout the word. eighteen species grow naturally in iran of which four species are endemic. experimental: this reseach has been carried in medicinal plants research station in yazd province with the coordinates of longitude and latitude 55 31 49 northly, 27 15 54 east to heigh of 1...

This study aimed to evaluate the antimicrobial efficacy of combination ?-polylysine (?-PL) and carvacrol (Car) against foodborne pathogens, Escherichia coli Staphylococcus aureus. The minimum inhibitory concentrations (MICs) ?-PL E. S. aureus were 25 ?g/mL (320 ?g/mL) 12.5 ?g/mL), respectively. Checkerboard assays showed that Car exerted synergistic effects with fraction concentration index (FI...
