Evaluation of in-vitro and in-vivo antimicrobial potential of Typha elephantina leaves extracts using Cyprinus carpio as a research model.

Present study investigate the in-vitro antibacterial and antifungal potential of Typha elephantina leaves aqueous extract (T. Eaq), ethanolic extract (T. Eeth) and methanolic extract (T. Emth) at different dosages against selected bacteria and fungi using dis diffusion method and Potato Dextrose Agar method. The study was also proceeded in- vivo against one strain of fungi (Aspergillus niger) using aqueous (T. Eaq) extract only. In-vitro study showed that Citrobacter freundii was highly sensitive while Salmonella typhimurium was the least among all. The antifungal activity was dose dependent and differs according to the fungal strain. Aspergillus niger was highly sensitive in order of aqueous extract (T. Eaq), ethanolic extract (T. Eeth) and methanolic extract (T.Emth), followed by Alterneria solani, Candida albicans and Aspergillus ustus. The in-vivo antifungal study was carried using Cyprinus carpio which were first infected with Aspergillus niger and then treated with (T. Eaq) at different doses. During in-vivo study various hematobiochemicl parameters and bio-accumulative stress of some heavy metals were assessed. Highly significant (P<0.05) remedial effects were observed at day 21st of treatment with extract at 100mg/ kg body weight. Differential accumulation was found i.e in skin the accumulation was highest followed by intestine gills and muscles tissues. Liver showed least accumulation.
