MicroPhage is a medical devices company that has developed advanced diagnostic technology for detection of bacterial infections and their antibiotic susceptibility. The company’s novel mechanism uses bacteria-specific viruses (bacteriophages) that serve as markers to identify specific bacteria in patient samples. The bacterial viruses are then used in conjunction with antibiotics to identify what drugs the patient’s infecting bacteria is susceptible to. Due to the high reproduction rates of viruses, the company’s diagnostic products produce results in one to four hours as compared to one to two days in traditional culture assays, providing doctors with the ability to more quickly develop therapeutic regimens, a key factor in treating infections. The fast identification of specific bacteria, as well as the bacteria’s antibiotic susceptibility, is essential for the successful treatment of active infections.
