Protection of ornamental gold fish Carassius auratus against Aeromonas hydrophila by treating Ixora coccinea active principles

Effect of Henna (Lawsonia inermis) extract on the immunity and survival of common carp, Cyprinus carpio infected with Aeromonas hydrophila

“…Similar results were found in Carassius auratus fed crude extracts and purified fractions of Ixora coccinea incorporated in diet (Anusha et al 2014).…”

“…In another study, among various doses of an aqueous extract of Polygonum minus leaf, intraperitoneally injected to African catfish, Clarias gariepinus, only the dose of 15 mg kg -1 BW of plant extract could significantly improve lysozyme activity 2 days post-treatment (Veerasamy et al 2014). Similar results of elevated lysozyme activity following herbal treatments have been reported Wu 2003, 2004;Rao et al 2006;Yin et al 2006;Anusha et al 2014).…”

“…Previously, enhancement of phagocytic and NBT activities following administration of herbal products in fish species have been reported in a number of studies (Rao et al 2006;Sahu et al 2007;Punitha et al 2008;Pratheepa et al 2010;Sharma et al 2010;Behera et al 2011;Uthayakumar et al 2014b;Anusha et al 2014).…”

“…Similarly, Quil-A, a fraction from Quillaja saponaria Molina, has enhanced serum bactericidal activity in Salmo gairdneri Richardson (Grayson et al 1987). In addition, an increase in serum bactericidal activity in tilapia (Divyagnaneswari et al 2008) in Indian major carp (Rao et al 2006), in common carp (Alishahi and Abdy 2013) and in ornamental gold fish (Anusha et al 2014) has reported after the administration of various herbal extracts.…”

“…Similar results were found in Carassius auratus fed crude extracts and purified fractions of Ixora coccinea incorporated in diet. Following challenge with highly virulent A. hydrophila AHV-1 the control diet fed fishes succumbed to death within 5 days at 100 % mortality whereas crude extracts and purified fractions fed groups survived 60 and 80 %, respectively, after 10 days (Anusha et al 2014).…”
