Project Summary

Increasing pressure on the use of antibiotics in animal production due to concerns of antibiotic resistance in human pathogens is demanding the development of alternative strategies to maintain the animal health and efficient production. The iodination of water has been identified as a means to improve animal performance, particularly in the poultry industry. Iodine has been used as an antimicrobial agent under several applications, however, it is unclear how water iodination and what concentration results in improved animal performance. We hypothesize that iodinated water can improve performance either by reducing pathogen load, or by altering the intestinal microbial community. BioLargo Water, Inc., specializes in leveraging iodine chemistry for applications in water treatment. To further develop iodinated water as a useful strategy in animal production, it is key that the impacts of iodinated water on the population of microbes in the intestinal tract (microbiota) including endemic pathogens are identified. Through this initial collaboration Biolargo Water and the lab of Dr. Willing will come together to study how iodionated water impacts the normal microbial population of poultry, and the effect on enteric pathogens including Salmonella. We will also determine whether there is any effect on the functioning of the intestinal tract including alterations in innate immunity and mucosal defense.
