Infectious diseases represent a significant cause of mortality across the world in both developed and developing countries. Sepsis is one such disease that presents everywhere. It causes between six and nine million deaths a year globally, representing a significant cause of death across the world. Sepsis often requires intensive care over several weeks so even when a full recovery is made, the costs are huge to both the individual and the health system. However, it is chronically underestimated as an issue worldwide. Treatment of sepsis requires administration of appropriate antibiotics as early as possible. However, broad-spectrum antibiotics are administered at the hospitals until the infecting bacterial species is identified. This is because current identification methods rely on the time-consuming blood culture. A novel 'Tm Mapping method' has been developed to identify the bacterial species in about three hours without the need for blood culture.
