Title: Purification and characterisation of Vibriophage isolated from Mangalavanam mangrove
Author: Archana,Kishore; Dr.Sarita,Bhat G
Abstract: The temperate, filamentous phage ФMV -5 isolated from Mangalavanam mangrove of Kochi, using the environmental strain of Vibrio sp. MV-5 shares many similar properties with other marine phage isolates, while also remaining unique. The study has revealed that the interaction of temperate phages and the microbial population in the marine environment may contribute significantly to microbial genetic diversity and composition by conversion and transduction and which requires greater study.Prophages contribute a substantial share of the mobile DNA of their bacterial hosts and seem to influence the short-term evolution of pathogenic bacteria. Automated methods for systematic investigation of prophages and other mobile DNA elements in the available bacterial genome sequences will be necessary to understand their role in bacterial genome evolution. In the past, phages were mainly investigated as the simplest model systems in molecular biology. Now it is increasingly realized that phage research will be instrumental in the understanding of bacterial abundance in the environment. One can predict that phage research will impact diverse areas such as geochemistry and medicine. Success will largely depend on integrative multidisciplinary approaches in this field. Clearly, further studies are required to understand how vibriophages interact with Vibrios to promote this organism's acquisition of the critical genes which alter its virulence or adaptation to its environmental niche.It is evident from this study and comparison with those reports cited above that vibriophage ФMV-5 is a previously unreported bacteriophage. It is recommended that the minimum requirement for reporting a new phage should be novel morphological markers and a description of host range, both of which have been achieved in this study.
