“…multifiliis infection under in vivo conditions. Zhang et al (2013) Reducing the infection prevalence and intensity by increasing the TA concentration may be due to the higher number of hydroxyl groups in the reaction environment and thus the formed complexes with extracellular and water-soluble proteins in the cell membrane (Athanasiadou & Kyriazakis, 2004;Gharibzahedi & Mohammadnabi, 2016). Although the theronts were eradicated at almost the same range of TA dose under the in vitro and in vivo experiments, a longer exposure time in the in vivo trials shows that a natural bioactive compound in laboratory studies may be more efficient to control the infection.…”

The in vitro antiparasitic effect of polyphenol tannic acid (TA) on Ichthyophthirius multifiliis theronts and tomonts was evaluated. In vitro antiparasitic assays revealed that TA in a dose- and time-dependent pattern through the damage of parasite plasma membrane could be 100% effective against I. multifiliis theronts at concentrations of 8 and 11 ppm during all the exposure times (45-270 min). The tomonts proliferation was completely inhibited by penetrating TA (at least 15 ppm for 22-hr exposure) into encysted tomont across the cyst wall. However, 10 ppm TA could result in a ninefold decrease in the population of live tomonts compared to the control group (p < 0.05). Although at theront concentrations of over 6,000 per zebrafish (Danio rerio), a 100% prevalence of ichthyophthiriasis during a 5-day exposure was recorded, results of in vivo tests showed that the parasite that pretreated up to 10 ppm TA for 70 min had not any capability to infect the studied zebrafish population. The acute toxicity (96 hr-LC ) of TA for zebrafish was 19.51 ppm. Thus, TA can be considered as a natural therapeutant to safely and efficiently improve the health of aquatic systems by controlling ichthyophthiriasis.

“…2). We have recently found total phenolic content of NEO was 319.3 ± 5.7 mg gallic acid/g extract according to the Folin-Ciocalteu method [40]. Caffeic acid derivatives, especially, chlorogenic and 2-O-caffeoylmalic acid (71.5-76.5%) are the main phenolics in U. dioica leaves [41].…”

“…These phenolic derivatives at high concentrations medium can breakdown the microbial cells via their interaction with proteins present in the cytoplasmic membrane and leakage of ions and other cell content [4]. Use of NEO and NEs loaded with this phenolic rich-ingredient had a strong antibacterial activity on some pathogens especially Gram-positive bacteria [40]. Antibacterial activities of the most dominant constituents present in NEO; such as, neophytadiene, phytol, ␤-ionone and hexahydrofarnesyl acetone had been also reported [42].…”

“…Similar to other previous researches, the higher turbidity of the emulsion meant the larger droplet size. Gharibzahedi et al (2016) showed the effect of droplet size on the nanoemulsion turbidity by a model. In that model, when the droplet size was lower than 100 nm, the increase of particle diameter has risen the turbidity.…”

As many spices essential oil, black pepper (Piper nigrum) oil, which produced by steam distillation has shown the antimicrobial activity in many researches. However, essential oil was often hydrophobic and dispersed incompletely in food matrix. In our work, an oil-in-water nanoemulsion of black pepper oil was prepared by high speed homogenization method. In order to well disperse essential oil in water, the surfactant polyoxyethylene sorbitan monooleate (Tween 80) was utilized with the surfactant:oil ratios from 1:3 to 2:1. The other component of the nanoemulsion was soya oil, the high chain triglycerides in soya oil prevented the Oswald ripening of essential oil droplets by increasing their hydrophobicity. After changing the component concentration, the nanoemulsion was the most stable with 20 % oil phase, 6:4 pepper oil -soya oil ratio and 1:1 surfactant oil ratio. At 9,000 rpm and 30 minutes stirring, the average droplet size was 61.9 nm with 0.462 PdI (polydispersity index). After 30-day storage, the particle size increased to 87 nm at ambient temperature and 130 nm at 5 o C.
