The beauties and the bugs: A scenario for designing flower strips adapted to aphid management in melon crops
Publication date: September 2019Source: Biological Control, Volume 136Author(s): Alexandra Schoeny, Antoine Lauvernay, Jérôme Lambion, Christophe Mazzia, Yvan CapowiezAbstractFlower strips appear to be a promising lever for promoting pest control but a careful selection of the plant species used is needed prior to implementation to avoid possible negative side effects. In the case of open field melon crops, the main pitfall would be to generate aphid and aphid-borne virus reservoirs near the crops. Combining biotests under controlled conditions and data from the literature, we assessed 18 candidate plant species, and rul...

Effect of low ‐ or high‐CP diet with cold‐pressed oil supplementation on growth, immunity and antioxidant indices of growing quail
In conclusion, quails fed a diet containing 24% or 26% CP or diets supplemented with Mar or Thy oils or both exhibited improvement in the performance, lipid profile, immunity and antioxidant capacity without any detrimental impacts on the other studied parameters.

Herbs and Spices- Biomarkers of Intake Based on Human Intervention Studies – A Systematic Review
AbstractCulinary herbs and spices have been used as both food flavoring and food preservative agents for centuries. Moreover, due to their known and presumptive health benefits, herbs and spices have also been used in medical practices since ancient times. Some of the health effects attributed to herbs and spices include antioxidant, anti-microbial, and anti-inflammatory effects as well as potential protection against cardiovascular disease, neurodegeneration, type 2 diabetes, and cancer. While interest in herbs and spices as medicinal agents remains high and their use in foods continues to grow, there have been remarkably...

Unveiling the Antifungal Potential of Two Iberian Thyme Essential Oils: Effect on C. albicans Germ Tube and Preformed Biofilms
Conclusion
This study highlights the antifungal potential of two Iberian endemic thyme species: T. camphoratus and T. carnosus. Of relevance, the results demonstrated that both oils were able to inhibit the growth of Cryptococcus neoformans and several dermatophyte strains. Moreover, the oils were very effective in inhibiting C. albicans germ tube formation at concentrations well below the MIC and in a much higher extend than fluconazole, an antifungal drug widely used in the clinic. Finally, T. carnosus oil was more effective in decreasing yeast mitochondrial activity and disrupting preformed biofilms in C. albicans. Ove...

The effect of an addition of marjoram oil on stabilization fatty acids profile of rapeseed oil
Publication date: Available online 9 April 2019Source: LWTAuthor(s): Radosław Kowalski, Grażyna Kowalska, Urszula Pankiewicz, Artur Mazurek, Marzena Włodarczyk-Stasiak, Monika Sujka, Jakub WyrostekAbstractCurrently, natural antioxidants and substances with a protective effect on fatty acids are used more and more often instead of synthetic compounds that may have a negative impact on human health. This is related to the prevailing trend of promoting healthy and organic food. Essential oils are interesting in this respect because studies confirm their antioxidant properties. The aim of this study was to analyse the effec...

Molecules, Vol. 24, Pages 1270: In Vitro Activity of Essential Oils against Saprolegnia parasitica
Mancianti
Saprolegnia spp. water molds severely impact fish health in aquaculture, fish farms and hobby fish tanks colonizing mature and immature stages of fishes, as well as eggs. Considering that there are no drugs licensed for treating and/or control the organism, efficient and environmental low-impact methods to control these oomycetes in aquaculture are needed. The aim of the present report was to evaluate the in vitro sensitivity of Saprolegnia parasitica to essential oils (EOs) from Citrus aurantium L., Citrus bergamia Risso et Poiteau, Citrus limon Burm. f., Citrus paradisi Macfad, Citrus sinensis Osbeck, Cinna...

Molecules, Vol. 24, Pages 1161: Antibacterial and Biofilm Inhibitory Activity of Medicinal Plant Essential Oils Against Escherichia coli Isolated from UTI Patients
In this study, we have investigated the antibacterial activity of five medicinal plant essential oils against UTIs caused by E. coli using disc diffusion and minimal inhibition concentration (MIC) methods. In addition, biofilm inhibitory action of oils was realized by crystal violet. Gas chromatography–mass spectrometry (GC–MS) analysis showed a variability between oils in terms of compound numbers as well as their percentages. Antibacterial activity was observed only in cases of Origanum majorana, Thymus zygis and Rosmarinus officinalis, while Juniperus communis and Zingiber officinale did not ...

Marjoram extract down-regulates the expression of Pasteurella multocida adhesion, colonization and toxin genes: A potential mechanism for its antimicrobial activity.
This study provides an in vitro research framework to investigate the antibacterial activities of 5 herbal (marjoram, garlic, onion, cinnamon and black seed) oil extracts against 16 multidrug-resistant (MDR) and virulent P. multocida serogroup A isolates recovered from dead and clinically diseased rabbits. Pathogenicity of the screened isolates was further proven experimentally and was verified by PCR analyses of 5 randomly selected virulence genes encoding attachment and colonization proteins (ptfA, pfhA, and omp87), sialidases (nanB) and dermonecrotoxin (toxA). A total of 12 P. multocida isolates were highly pathogenic w...

A database-driven approach identifies additional diterpene synthase activities in the mint family (Lamiaceae) [Metabolism]
Members of the mint family (Lamiaceae) accumulate a wide variety of industrially and medicinally relevant diterpenes. We recently sequenced leaf transcriptomes from 48 phylogenetically diverse Lamiaceae species. Here, we summarize the available chemotaxonomic and enzyme activity data for diterpene synthases (diTPSs) in the Lamiaceae and leverage the new transcriptomes to explore the diTPS sequence and functional space. Candidate genes were selected with an intent to evenly sample the sequence homology space and to focus on species in which diTPS transcripts were found, yet from which no diterpene structures have been previ...
