Abstract
|
|
|
The susceptibility test and serotyping of pseudomonas aeruginosa isolated in natural, hospital environment and patients were done.
Antibiotic drugs used in test were commercial agents being sold in drug stores. Patient strains showed very high resistance rates of 87% to carbenicillin, 69.7% to cefoperazone and hospital strains showed higher resistant rates of 16.8% to carbenicillin, 21.5% to cefoperazone than wild strains susceptible completely.
All strains resisted to gentamicin and kanamycin and the resistant rate accessed to 100% respectively.
Wild strains and hospital strains were relatively susceptible to amikacin and tobramycin, high cost aminoglycosides, but patient strains resisted highly to both drugs. Resistance rate of each drug was 78.3% and 100%.
There was no significant difference in multiple drug resistance by serotypes.
Numbers of tested drugs which wild strains were multiply resistant were 9 to 12 and patients and hospital strains showed multiple resistance of 9 to 16 of drugs.
Serotypes of patient strains were mainly B, E, G, A types but I types were main serotypes of hospital and wild strains and G, E, A, types followed sequently. H. J, K. L, M, N types had not been typed in any groups at all.
