Two hundred and fourty eight strains of Pseudomonas aeruginosa isolated from clinical materials at Department of Bacteriology in National Medical Center and Han-il Hospital during January to November in 1973, were typed serologically by Hommo's agglutination method utlizing a routine set of 13 standard sera. In addition, their susceptibitily to several kinds of antibiotics were determind. The following results were obtained; One hundred seventy eight strains(71.77%) were typable with an occurence of type $T_8$ in 41 strains(16.53%), type $T_5$ in 36(14.52%), type $T_3$ in 24 strains(9.68%) and small numbers of strains were distributed in lither types. Seventy strains(28.23%) were nontypable. The rate of isolation of Pseudomonas by clinical meterials was shown as 49.19% in ous, 16.53% in sputum and 8.87% in urine; the isolation rate of 1.21-3.15% was shown in other clinical meterals and the definite distribution rate could not be observed in the serotype by different materials. Majorities of strains used in this experiment of isolates were resistant to common antibiotics but Gentamycin and Carbenicillin, known relatively as sensitive antibiotics to Pseudomonas aeruginosa, were observed resistance of 2.44-10.5% and 16.69-57.8%. Moreover any particular relationship between serotype and the sensitivity of antibiotics was not identified.
