The purpose of this study was to compare pathogens isolated from lower respiratory specimens and blood cultures from patients hospitalised at Clinic of Haematology, Clinical center, Skopje, Macedonia, during two year period (September, 2000 – September, 2002).


85 patients hospitalised at Clinic of Haematology were chosen for having positive microbiological findings both in sputum and in blood culture. Cultivation, isolation, identification and antimicrobial susceptibility testing were made using standard microbiological laboratory methods.


Sputum isolates were: Candida albicans 25, Streptococcus pneumoniae 17, Pseudomonas aeruginosa 16, Candida spp. 11, Klebsiella spp. 11, Staphylococcus aureus 8, E. coli 7, Acinetobacter spp. 4, Haemophilus influenzae 4 and Streptococcus pyogenes 2. Blood isolates were: Staphylococcus coagulase-negative 30, Staphylococcus aureus 15, E. coli 10, Pseudomonas aeruginosa 9, Enterococcus 6, Klebsiella spp. 6, Acinetobacter spp .4, Candida spp. 2 and Candida albicans 1. Nineteen 19 patients had identical findings both in their sputa and blood cultures: Pseudomonas aeruginosa 5, Staphylococcus aureus 5, Klebsiella spp. 3, Acinetobacter spp. 2, E. coli 1 and Candida albicans 1. Their bacterial antimicrobial susceptibility testing showed similar resistance pattern.


Candida and Gram-negative bacilli were predominant pathogens from lower respiratory tract samples. Gram-positive cocci (Staphylococcus) were main pathogen in blood cultures. Identical findings together in sputa and blood cultures in 19 patients showing similar resistance pattern have same origin.
