Characterization of putative pathogenic isolated from ballast water.

Background And Aim: is ubiquitous in marine-associated environments and has been increasingly recognized as a significant human pathogen that can cause serious infections mainly associated with exposure to seawater and ingestion of raw seafood. This study aimed to isolate and characterize from ballast water of ships berthed at Port Klang, Malaysia.

Materials And Methods: Ballast water was sampled from nine ships docked at Port Klang, Malaysia.

An ultrasensitive hollow-silica-based biosensor for pathogenic Escherichia coli DNA detection.

A novel electrochemical DNA biosensor for ultrasensitive and selective quantitation of Escherichia coli DNA based on aminated hollow silica spheres (HSiSs) has been successfully developed. The HSiSs were synthesized with facile sonication and heating techniques. The HSiSs have an inner and an outer surface for DNA immobilization sites after they have been functionalized with 3-aminopropyltriethoxysilane.
