Rapid preliminary diagnosis of anaerobic bacterial infections. I. Natural fluorescence of pus, purulent fluids and dressing under UV radiation]

For evaluation of usefulness of natural fluorescence of clinical materials in UV radiation as rapid diagnostic method of infections with anaerobes, 405 samples of pus, bloody-purulent fluids, blood, wound secretions, dressings and other materials were investigated. Occurrence of red-brick UV fluorescence of clinical materials was compared with results of culture aimed at isolation of non-sporeforming anaerobes from "B. melaninogenicus group (P. melaninogenica, P. intermedia and P. saccharolytics). Significant correlation red-brick fluorescence of clinical materials resulting from UV irradiation with presence in these materials of anaerobes such as P. melaninogenica, P. intermedia and P. asaccharolytics was detected. Investigation of clinical materials with application of fluorescence in UV radiation lasts only 1-2 minutes and together with preparation and microscopical inspection which is Gram-stained--only 15-20 min. Positive results of this test may constitute a basis for rapid, preliminary identification of the etiologic factor and for direction of chemotherapy in the early period of infection.
