Hemato – Immunological and biochemical parameters, skin antibacterial activity, and survival in rainbow trout (Oncorhynchus mykiss) following the diet supplemented with Mentha piperita against Yersinia ruckeri

The potential benefits of Mentha longifolia on growth performance and innate immunity parameters in Caspian kutum ( Rutilus frisii kutum )

“…The administration of dietary feed additives, such as medicinal plants, as alternates to antibiotics, has increased in response to recent dramatic growth seen in the aquaculture industry worldwide (Adel et al., 2020; Citarasu, 2010; Ghehdarijani et al., 2016; Saleh, Ismail, Sayed, Zaghloul, & Saleh, 2020; Santos et al., 2019). Furthermore, the increase noticed in the use of these additives is due to the fact that they can be easily prepared, they are cheap, and they have limited undesirable effects on either fish or the environment (Adel, Pourgholam, et al, 2016; Adel, Sakineh Yeganeh, Dadar, Sakai, & Dawood, 2016; Banaee, Sureda, Mirvaghefi, & Rafei, 2011; Van Hai, 2015). In connection with the earlier studies (Adel, Abedian Amiri, et al, 2015; Adel, Safari, et al, 2015; Banaee et al., 2016; Heydari et al., 2020), ML incorporated with fish diets in the current study positively influenced the Caspian kutum by both promoting their immune responses (more evidently at the mucosal surface which is the first line of defence) and boosting their growth performance significantly.…”

“…Epidemics and pathogens such as Lactococcus garvieae , Streptococcus iniae , Yersinia ruckeri and Aeromonas hydrophila can in some cases lead to economic bankruptcy (Adel, Pourgholam, Zorriehzahra, & Ghiasi, 2016; Chen, Li, Yao, & Zhang, 2019; Halimi, Alishahi, Abbaspour, Ghorbanpoor, & Tabandeh, 2020). Although antibiotics can reduce the bacterial burden of the environment, excessive use of antibiotics can be harmful.…”

“…Systemic infection of fish to opportunistic bacteria such as L. garvieae , S. iniae , Y. ruckeri and A. hydrophila usually leads to internal bleeding, subcutaneous haemorrhage, edema as well as accumulation of infectious fluids in abdomen and affects vital organs such as the liver, spleen and kidney(Adel, Pourgholam, et al, 2016; Chen et al., 2019; Halimi et al., 2020). Therefore, measuring blood biochemical parameters, immunological factors and serum bactericidal activity can indicate the health status of fish dealing with pathogens.…”

Practical diets with essential oils of plants activate the complement system and alter the intestinal morphology of Nile tilapia

“…Recently, some authors have shown that peppermint EO has antiparasitic effect against Ichthyophthirius multifiliis (Valladão et al., ) and monogeneans (Costa et al., ; Hashimoto et al., ; Malheiros, Maciel, Videira & Tavares‐Dias, ), and when used in water did not cause negative effects on fish haematology (Hashimoto et al., ). The enhancement of haematological and immune parameters was observed in rainbow trout, Oncorhynchus mykiss (Walbaum) (Adel, Pourgholam, Zorriehzahra & Ghiasi, ), and Caspian white fish, Rutilus frisii kutum (Kamenskii) (Adel, Amiri, Zorriehzahra, Nematolahi & Esteban, ), fed with ethanolic extract of peppermint, and in Asian seabass, Lates calcarifer (Bloch), fed with a powder of peppermint leaves (Talpur, ). Recently, Ribeiro et al.…”

A novel screening method for the detection of Pseudoalteromonas shioyasakiensis, an emerging opportunistic pathogen that caused the mass mortality of juvenile Pacific abalone (Haliotis discus hannai) during a record-breaking heat wave

“…For example, the skin-secreted mucus of sea bream and sea bass was shown to block or limit bacterial growth (i.e., lytic activity) based on 24 h growth curves (Sanahuja et al, 2019); the skin-secreted mucus ofSalmosalar had high levels of NK-lysin, and strong bacteriostatic properties (Valero, Cortes, & Mercado, 2019); and the skin-secreted mucus of Amphiprionclarkii showed robust time-and dose-dependent bactericidal and antiparasitic activity (H. Wang, Tang, Zhang, & Ding, 2019). In addition, skin mucus showed higher antimicrobial activity against tested pathogens in experimental rainbow trout with beneficial dietary additive (Adel, Pourgholam, Zorriehzahra, & Ghiasi, 2016;Mansouri Taee, Hajimoradloo, Hoseinifar, & Ahmadvand, 2017). It was also shown that stressed corals produced mucus with higher bioactive content and increased antibacterial activity (Wright, Strader, Genuise, & Matz, 2019); that the mucus ofEiseniafoetida exhibited strong antimicrobial activity against human bacterial and fungal pathogens (Andleeb et al, 2016); and thatHelix aspersa mucus had strong antibacterial effects on Pseudomonasaeruginosa and weak effects on Staphylococcusaureus (Fuochi et al, 2017).…”
