| Outline of Final Research Achievements |
The diagnosis of pneumonia is still difficult now. We observed Gram stained slides of sputum collected from patients with pneumonia for observation with an optical microscope using a dedicated camera that can analyze spectral data in detail. With this camera we were able to obtain data dividing the image in the neutrophils every 5 nm in the wavelength range of 400 to 1000 nm of light. By analyzing the obtained data with dedicated software, it is possible to distinguish differences in color tone that can not be discerned by human eyes. It was shown that the difference in color can be distinguished and classified as the difference in activation of neutrophils.
