[Rapid preliminary diagnosis of anaerobic bacterial infections. I. Natural fluorescence of pus, purulent fluids and dressing under UV radiation]. / Szybka, wstepna diagnostyka zakazen bakteriami beztlenowymi. I. Fluorescencja naturalna ropy, plynów ropnych i opatrunków pod wplywem promieniowania UV.

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.

Investigation of the presence of volatile and non-volatile fatty acids (C1-C6) in pus, purulent fluids and dressing by application of gas chromatography]. / Szybka wstepna diagnostyka zakazen bakteriami beztlenowymi. II. Badanie obecnosci lotnych i nielotnych kwasów tluszczowych (C1-C6) w ropie, plynach ropnych i opatrunkach przy zastosowaniu chromatografii gazowej.

Studies were performed in the years 1986-1990 and dealing with 405 clinical materials originating from infections within the abdominal cavity, maxilla, reproductive organ, post-operative wounds as well as dressings, extremities, blood, bile and other types of material and usefulness of analysis by gas chromatography of presence of lower fatty acids in materials for rapid and preliminary diagnostics with strictly anaerobic bacteria was confirmed. Presence in chromatograms of isobutyric, butyric isovaleric, valeric, isocaproic and caproic acid, and partly of propionic acid, is a good indication of infection with strictly anaerobic bacteria. Moreover, presence of succinic acid may suggest presence of anaerobic infection, similarly as presence in chromatograms of three or more various lower fatty acids. Rapid, approximative diagnosis of anaerobic bacteria by application of gas chromatography is worth of broader application. Investigation of clinical material by this method lasts only 1-2 hours and obtained results my present a basis for preliminary diagnosis of the etiological factor and for direction of chemotherapy, which is very important in most early period of treatment of infections.
