The antibacterial and physiological effects of pure and nanoencapsulated Origanum majorana essential oil on fish infected with Aeromonas hydrophila

New Tricks for Old Guys: Recent Developments in the Chemistry, Biochemistry, Applications and Exploitation of Selected Species from the Lamiaceae Family

“…O. majorana EO and its nanocapsules were evaluated recently for their antibacterial activity in silver catfish, Rhamdia quelen, infected with Aeromonas hydrophila. [265] All treatments improved the survival of infected fish, but authors suggest daily baths containing 20 μL/L EO or 5 μL/L nanoencapsulated EO for five consecutive days because these are the lowest effective concentrations tested which did not interfere with the metabolic parameters of the animals. The in- [266] All treatments showed antibacterial activity, and in almost all cases, the activity of the nanoemulsions was superior to their essential oil counterparts.…”

“…The administration of EO in the diet is becoming an interesting tool also in aquaculture, with the aim of exploiting above all the antimicrobial activity of these phytocomplexes. O. majorana EO and its nanocapsules were evaluated recently for their antibacterial activity in silver catfish, Rhamdia quelen , infected with Aeromonas hydrophila . All treatments improved the survival of infected fish, but authors suggest daily baths containing 20 μL/L EO or 5 μL/L nanoencapsulated EO for five consecutive days because these are the lowest effective concentrations tested which did not interfere with the metabolic parameters of the animals.…”

Chemical composition and insecticidal potential of different Origanum spp. (Lamiaceae) essential oils against four stored product pests

“…Different activities of Origanum spp. such as antioxidant (Dutra et al, 2019), cytotoxic (Coccimiglio et al, 2016), antimicrobial (Lesjak et al, 2016;Reyes-Jurado et al, 2019), anti-acetylcholinesterase (Abou-Taleb et al, 2016;Hajlaoui et al, 2016;López et al, 2018), antibacterial (da Cunha et al, 2018;Wijesundara & Rupasinghe, 2018), repellent (Govindarajan et al, 2016;La Pergola et al, 2017;Giatropoulos et al, 2018), antifungal (Vinciguerra et al, 2018), allelopathic (Boukaew et al, 2017), phytotoxic (Ibáñez & Blázquez, 2018;Grul'ová et al, 2019) insecticidal (Kim et al, 2016;Szczepanik et al, 2018;Benelli et al, 2019) have been determined in a number of studies.…”
