Studies on Pseudomonas Aeruginosa Isolated from Chronic Wounds / 대한정형외과학회잡지

ABSTRACT

49 strains of Pseudomonas aeruginosa were isolated from chronic wounds associated with orthopedic surgical field at Taegu armed forces general hospital. In the present report, authors have studied the Pyocin type of isolated strains by Gillies and Govans method. Also observed various interrelationship in associaton with Pyocin type, Pyocyanine formation, Oxidase reaction and antibiotic sensitivity. The results were obtained as follows; 1) Among the 49 strains tested in term of pyocin type, 41 strains(81.6%) were found to be typable and 8 strains (16.4%) to be untypable. Among the pyocin type of 41 typables, unclassified type was the most prominent type 17 strains (41.5%) and followed by type I(11 strains), 10 (3 strains), 5 (2 strains) and other type. 2) In the relationship among pyocyanine formation, oxidase reaction and pyocin type, no definite conclusion can be reached due to the paucity of tested strains except that more strains belong to the pyocin type I of the Pyocyanine negative strains. 3) In antibiotic sensitivity of isolated strains tested by plate dilution method, most of all strains were resistant to Kanamycin and Neomycin but few strains were moderate sensitive to Colistin, Polymyxin B, and Terramycin. 4) The Pyocin type of isolated strains were not related with antibiotic sensitivity to Colistin, Polymyxin B and Terramycin substantially.
