Patents Phage that Kills Vibrios


Dr. Indrani Karunasagar, director of research at the UNESCO Centre for Marine Biotechnology, has received a patent for “the process of preparing a consortium of bacteriophages for controlling luminous bacterial disease in shrimp larvae.”  Bacteriophages are viruses that infect, replicate and kill bacteria.


Regarding the difficulties associated with the application of phages, like strain specificity and rapid clearance by the immune system, Indrani said those difficulties can be overcome with careful management.  She said the advantages of bacteriophages “stems from their ability to remain only as long as the host bacterium is present,” adding that “no serious side effects have been reported with the phage consortia developed by her research group.’’  Phage research leading to a commercial product and patent has been the result of over two decades of intense study using molecular tools.
