The relative efficacy of the isolated pure compound, extracted from Carica papaya seed has been tested against live fish, Channa punctatus infected with pathogenic strains of KlebsiellaPKBSG14 (gene bank accession no.KJ162158) at a dose of 0.75 CFU/ml in vivo. The isolated compound has been characterized by chromatography and mass spectroscopy studies using FTIR, 1HNMR and 13c NMR to identify as well as to determine the nature of the pure compound. This study revealed the extracted biological molecule is oleic acid, a long chained saturated fatty acid (LFAs) with a molecular formula C18H34O2. Later this compound was analyzed for its efficacy as an antibacterial agent in vivo through cytotoxicological and genotoxicological assays. A dose of 0.5 mg/kg and 1 mg/kg b.w of isolated pure oleic acid has been tested and it showed effective result in regard to DNA fragmentation, comet tail length and toxicity biomarkers like ROS generation. The results of in vivo studies showed similar effects on spleen cells with regard to cell viability by PI staining, cell cycle analysis and also Annexin-FITC assay. Thus, the overall results suggest that oleic acid increases drug bioavailability and thereby has a better chemo-preventive action against bacterial infection in vivo.
