determine bacteria is growing the bacteria on agar and then identify the bacteria via the API system (analytical profile index). In some medical cases, 24 hours is too long to wait, especially if a patient needs antibiotics. Raman spectroscopy uses laser light to excite a spectrum specific to each molecule. This molecular specificity enables Raman spectroscopy to identify the species of bacteria without a lengthy growth period. Raman spectroscopy is non invasive and only needs one bacterium for detection. It is therefore faster than growing bacteria and identifying via the API system.
From other research groups we know that Raman spectroscopy is able to classify bacteria, albeit with limited breadth of bacterial types. The next step is to implement imaging techniques to make the identification even faster, so that those techniques can be used in hospitals to determine pathological bacteria, so that the treatment can be given faster. Furthermore, when a hospital is unsure whether the patient has a disease caused by bacteria usually they start treating the patient with antibiotics in case they are infected. If identification only take a few hours instead of two to three days, doctors would only prescribe antibiotics when necessary, thus decrease the risk of multiresistant bacteria.
