Biomacromolecules of chitosan - Bacopa saponin based LipL32 gene delivery system for leptospirosis therapy.

Leptospirosis is a severe bacterial infectious disease caused by the organisms belonging to the genus of Leptospira. The chitosan/Bacopa saponin/tripolyphosphate (CS/BS/TPP) nanoparticles conjugated with recombinant DNA vaccines were designed against Leptospirosis. Chitosan, a polysaccharide is suitable for delivery of drug, and gene due to its bio-compatible and biodegradable properties.

Prevention of quorum-sensing-mediated biofilm development and virulence factors production in Vibrio spp. by curcumin.

The increasing occurrence of disease outbreaks caused by Vibrio spp. and the emergence of antibiotic resistance has led to a growing interest in finding alternative strategies to prevent vibriosis. Since the pathogenicity of vibrios is controlled in part by quorum-sensing (QS) system, interfering with this mechanism would prevent the pathogenicity of vibrios without developing resistance.
