Abstract

The primary cause of morbidity and mortality is the soft tissue infections after bacterial infection with saltwater exposure. Bacteriophages were being considered to be bacteria that absorb viruses, so active bacteriophages can be applied theoretically to prevent bacterial infections. Chitosan, a partly deacidified natural polymer derived from a crustacean shell or fungus, which has antimicrobial potential. The present study aims to investigate bacterial and chitosan antibacterial activity against isolates of marine water. Five lytic phages in the allocated area of Shah Alam, Malaysia were isolated from marsh water and tested against five different seawater-isolated bacterial strains. Phage and disk diffusion experiments are used to assess the sensitivity profiles of the five isolated strains of marine water. The five isolates of bacteria, including small plaques and chitosan, were found to be susceptible to isolated phage.
