Silver Bullet Trials on EMS in Sinaloa


Following the identification of the bacterium that causes EMS/AHPNS, Dr. Donald Lightner’s research team at the University of Arizona conducted an experiment in conjunction with the Silver Bullet Water Treatment Company to test the effectiveness of the Silver Bullet system for eliminating Vibrio parahaemolyticus.  The Silver Bullet system has been effectively used to eliminate bacteria in HVAC (heating, ventilation, and air conditioning) systems and livestock drinking water systems by using a proprietary oxygenated gas to generate a powerful biocide in the water.  While the research team was confident the system would eliminate V. parahaemolyticus bacteria, it needed verification that it would not harm live shrimp larvae.  Consequently, in early September 2013, Dr. Lightner’s research team inoculated water in several test containers with V. parahaemolyticus and then introduced live shrimp larvae into the containers.  The Silver Bullet’s proprietary gas was then injected into the test containers.  Test results showed that the gas resulted in drastic drops in V. parahaemolyticus counts over a six-day period while leaving shrimp larvae unharmed.


As a result of the successful testing at the University of Arizona, Cuauhtemoc Castro, Sub-Secretary of Fisheries in the state of Sinaloa, Mexico, urged Silver Bullet to test the effectiveness of its system on a shrimp farm.  Testing was conducted by Drs. Bruno Gomez and Sonya Soto of the Federal Research Center on Nutrition and Development (CIAD) with the help Sergio Escutia, CEO of Aquastrat, a seafood company in Mazatlan, Sinaloa, Mexico.  In December 2013, test results determined that the Silver Bullet system was able to reduce and control Vibrio growth in an active commercial shrimp farm while maximizing shrimp survival.


Dr. Bruno Gomez said, “From our 47-day commercial field study and laboratory analysis of the Silver Bullet system, we found that Silver Bullet was able to reduce Vibrios with over 93.3% and 100% shrimp survival rates in a mesocosm environment”.


Silver Bullet is currently conducting additional tests to further verify these findings with CIAD’s lab in Sonora, Mexico.
