Abstract: Four hundred ninety-nine strains of Pseudomonas aeruginosa isolated from various non-human materials in a workmen's hospital, 201 strains of patient origin in this hospital, and 71 patient's strains obtained in other two control hospitals (771 strains all told) were typed serologically and by pyocine-typing methods of Gillies-Govan and of Darrell-Wahba. Those three tests were conducted three times at an interval of one week, and results were determined as a rule in agreement of at least two results in every method. All strains, except 136 non-agglutinable ones, could be typed serologically in the following order: Types 7, 8, 6, 5, 13, etc. Pyocine-types ranking high were Types 1, 10 and 3 by the G-G method, and similarly Types B, D and F by the D-W method. There is relation between serotypes and pyocine-types to a certain degree, and, judging from the result of the investigation, it is worth notice that the G-G method for pyocine-typing is usefull for subtyping some serotypes. The typing results of patient's strains obtained at the workmen's hospital differed surely from those obtained at the control hospitals. Tbere was no significant difference, however, between types of P. aeruginosa isolated from the pathological materials and those obtained from non-human sources (room-air, furnitures and other hospital equipments) in the hospital. The similarity may be mentioned about the data concerning wards from No.1 to No.7, where the patients were admitted in each separate class of disease. The isolation rates of P. aeruginosa among the words above, however, are fairy different one another, where Ward 2, a special institution of spinal injury indicates the greatest isolation percentage. The combination typing data of strains obtained at the workmen's hospital have been presented in detail in tables separately along each kind of material, dating, and location. Although it was impossible for the author make clear an epidemiological route of infection or of disemination of this organism, the contamination affairs from the patients to environments have been demonstrated in fairly number of cases, especially in cases with spinal injury and complication of uro-genital infections.
