GREENSBORO, NORTH CAROLINA, US, October 29, 2020 /EINPresswire.com/ -- After studying the existing science as a North Carolina start-up, Kepley BioSystems focused on two objectives in 2018: First, to prove that horseshoe crabs could be sustainably husbanded in aquaculture, and second, that a meticulously harvested substrate from their blood could offer a breakthrough in clinical diagnostics. Both goals would require overcoming daunting barriers that faced earlier efforts while expanding on the established role of horseshoe crab “blue blood” for medical sterility testing.

Undeterred, the group concentrated on addressing the growing threats from antimicrobial resistance and sepsis – and from the annual biomedical industry capture of several hundred thousand horseshoe crabs from their habitats with up to 30% mortality. The former posed an increasingly urgent need for rapid testing for bacteremia with parts-per-trillion sensitivity in human medicine, and the latter required an alternative to current practices to help protect this ancient species while ensuring drug and device safety.

Kepley documented this research in four articles, with the final two publications today and last week. From a far-reaching assessment of the study of horseshoe crabs to date, the group went on to prove novel approaches to feeding them and ensuring their wellbeing, while developing low-impact harvesting protocols for sustainable aquaculture. This alternative to wild capture could help secure the vital resource on which millions of patients depend for sterile, safe implantable medical devices and injectable drugs every year. It could also help ensure ample test supplies for a breakthrough in rapid patient screening to guide timely treatment of bacterial and fungal infections – and mitigate the risks of antimicrobial resistance when treating septicemia.

The first two publications made important contributions to the literature and spanned many disciplines, including: aquaculture, animal feed, infectious disease, diagnostic medicine, and ecology. And the last two round out the specifics with respect to sustainable husbandry, promising disruptive ecological and clinical benefits.

Since the inception of the pandemic, an area of particular interest has been coinfections leading to bacterial sepsis in the management COVID-19 patients with viral pneumonia, especially when blood culturing is impracticable. It has also been widely reported that sterility testing of SARS-CoV-2 vaccines could intensify pressures that further threaten the horseshoe crab viability as a species.

Kepley BioSystems horseshoe crab research has been generously supported by the National Science Foundation and the NC Sea Grant Agency, to date. The company is seeking investors and commercialization partners in diagnostics, aquaculture and agricultural feedstocks.
