The growth of antimicrobial resistance is creating a crisis in public health. Patients with a severe infection experience an increase in mortality risk measured in hours, but the current gold standard diagnostic for antibiotic susceptibility can take 2-5 days or longer because it relies on culturing bacteria.  Day Zero Diagnostics is developing a rapid, sequencing-based diagnostic that identifies, within hours, both the species and the antibiotic resistance profile of a bacterial infection. Day Zero Diagnostics was founded in May of 2016. We are located at the Harvard Life Lab and Harvard iLab, and also have strong collaborations with the labs of Dr. Doug Kwon at the Ragon Institute of MGH, MIT and Harvard and Dr. Mehmet Toner at MGH.
