Microorgansims isolated from the blood of patients hospitalized in clinical hospital department

The aim of the study was the microbiological analysis of blood cultures made in the Microbiological Diagnostics Lab in the period of 2003−2007. In the conducted studies a retrospective analysis of the evaluation of results of blood culture tests was made. The studies were conducted in the Microbiological Diagnostics Lab at the clinical Hospital No. 1 in Lublin. Blood for culturing was obtained from all departments of the hospital. For blood culturing, an automatic system of microorganisms’ growth detection was used, and the identification as well as drug resistance tests were made according to the recommendations of the National Recommendation Centre for Microorganic Drug Resistance. Generally, in the years of 2003–2007, 7049 of blood cultures were prepared. In total, in the given period, 1125 disease causing microorganisms were detected. The analysis did not evaluate the secondary isolates from the same patient. A secondary isolate was a subsequent culture of the same microorganism of the same antibiotic pattern in the period of 21 days. In the studies, the questionnaire by the authors was used for the collection of microbiological data.
