The Army is soliciting white papers for research on controlling polymicrobial environments, specifically developing bacteriophage-infused hygiene wipes to prevent urinary tract infections in female warfighters. The work involves phage-compatible formulation development, thermal stability and preservative testing, prototype wipe production, and regulatory compliance under MoCRA. A single contract is anticipated with a 12-month base period plus two 12-month option periods. White papers will be evaluated on scientific merit, management approach, program importance, and proposed cost, with selected offerors potentially invited to submit full proposals. No budget amount is specified.
