A total of 67 patients with blood system diseases and infectious complications were examined. During the period of the examination 139 microorganisms were isolated. Of these gram negative microorganisms constituted 51%, gram positive microorganisms--34.8% and fungal flora--14.2%. Most frequently the following gram negative microorganisms were isolated from the patients: Pseudomonas sp. (including P. aeruginosa), Klebsiella pneumoniae, Escherichia coli, Haemophilus influenzae. All isolated microorganisms retained sensitivity to imipenem, with the exception of individual strains of Pseudomonas sp.; the latter exhibited sensitivity to amicacin and ceftazidim. Cefotaxime was active with respect to 75% of K. pneumoniae strains and all E. coli strains, ciprofloxacin was active with respect to 43% of E. coli strains, 80% of K. pneumoniae strains and 83.4% of Pseudomonas sp. strains, cefepim was active with respect to 85.7% of Pseudomonas sp. strains and all E. coli strains, ceftazidim was active with respect to all Pseudomonas sp. and E. coli strains. 75% of K. pneumoniae strains, 77.8% of Pseudomonas sp. strains and 86% of E. coli strains retained sensitivity to amicacin. 25% of K. pneumoniae strains required testing for ESBL production. |
