In vivo antioxidant activities of the ethanolic extract of Zehneria scabra leaves on Salmonella enteritidis infected quails
Antioxidants are substances which are capable of protecting the body from damages caused by free radicals. A variety of free radical scavenging antioxidants exists in the body and many of them are derived from plant sources. The aim of the present study was to investigate the antioxidant activity of the absolute ethanolic extract of Zehneria scabra leaves on Salmonella enteritidis infected quails. Salmonella enteritidis infected quails were treated every day with different doses of plant
... ses of plant extract (9, 18 and 37 mg/ kg or oxytetracyclin 20 mg/ kg). After 12 days of treatment, the results showed that the different doses of this extract contributed in curing the infected quails, healing marked by the absence of Salmonella in animal's cloacal swabs cultured on SS Agar. On the other hand, treatment with different doses of plant extract resulted in a relative and significant (p < 0.05) decrease in the level of tissues antioxidant parameters such as CAT, SOD, POD, MDA and NO as compared to the animals of the negative control group. These results showed that the absolute ethanolic extract of Z. scabra leaf possess antioxidant and antisalmonellal properties necessary to eradicate the free radical produced during avian salmonellosis infection.
