Two hundred and fourty eight strains of Pseudomonas aeruginosa isolated from clinical materials at department of bacteriology in the National Medical Center and Han-il Hospital during January to November in 1973, were typed serologically by Homma's agglutination method utilizing a routine of 13 standard sera. in addition, their susceptibitily to several kinds of antibiotics were determined.
The following results were obtained:
One hundred seventy eight strains (71.77%) were typable with an occurrence of type ?? in 41 strains (16.53%), type ?? in 36 (14.52%), type T₃in 24 strains (9.68%) and small numbers of strains were distributed in other types. Seventy strains (28.23%) were nontypable.
The rate of isolation of Pseudomonas by clinical materials was shown as 49.19% in pus, 16.53% in sputum and 8.87% in urine: the isolation rate of 1.21-3.15% was shown in other clinical materials 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 assensitive antibiotics to Pseudomonas aeruginosa, there were observed resistances of 2.44-10.5% and 16.69-57.8%. Moreover, any particular relationship between serotype and the sensitivity of antibiotics was not identified.
