[Analysis of microorganisms isolated from febrile neutropenic children with neoplastic disease].
The microbiological evaluation of the blood was carried out as a continued monitoring of the microorganism culture using the colourmetric system VITAL 200 (bio-Mérieux). There have been analysed 4660 bacteriological research results of the peripheral blood, blood from Broviac and from Broviac liquid of the children suffering from cancer treated in the years 1997-2000 in the Pediatric, Hematology and Oncology Clinique of the State Clinical Hospital in Bydgoszcz. There have been gained 1032 positive cultures from KZZ, KZB, PZB. There have been recognized 259 bacteremia and 22 fungemia by the children with fever in the neutropenia period. In the analysed four years in the blood dominated Gram-positive bacteria. Among Gram-positive bacteria there were mostly Staphylococcus spp. (42.5%), mostly CNS, fewer numerous were Streptococcus spp. (14.5%) and Corynebacterium spp. (5.9%). Among Gram-negative bacteria mostly were isolated Acinetobacter spp. (25.6%), Pseudomonas spp. (9.7%), E. coli (13.8%), Enterobacter spp. (13.9%), Klebsiella spp. (9.2%). There were observed few infections by strains resistant to many antibiotics, S. maltophilia, B. cepacia, E. faecium, S. haemolyticus. All strains Staphylococcus spp. were sensitive to vancomycin. There have not been found Enterococcus spp. resistant to glycopeptides. Most active against Gram-positive rods were carbapenems and aminoglycosides.
