Abstract:
Objective To find out the distribution and changing trend of pathogens in positive blood cultures. Methods To analyze 183 isolates from 2010 blood specimens then the results were compared with the relative clinical data. Results A total of 183 strains were isolated from all blood specimens, of which 139 strains (76.0%) were identified as pathogens, where 69 strains (49.6%)being Gram-positive cocci, 57 strains (41.0%) gram-negative bacilli, and 13 strains (9.4%) fungi, respectively. The other 44 strains (24.0%) were contaminated. The major pathogens in 139 strains were Coagulase-negative staphylococci (40 strains, 28.8%), Pseudomonas aeruginosa (17 strains, 12.2%), Escherichia coli (15 strains, 10.8%), fungi 13 strains (9.4%) and Staphylococcus aureus (9 strains, 6.5%). Conclusion The dominant pathogens in positive blood cultures were gram-positive cocci, while gram-negative bacilli cultures were becoming less.
