BACKGROUND/AIMS: To study the distribution and drug resistance of pathogens causing blood stream infections (BSIs) and provide the evidence for clinical therapy after liver transplantation. METHODOLOGY: Blood samples were processed by the BACTEC 9120 blood culture system. Species identification was performed using the Vitek-2 system. The drug susceptibility of pathogens was performed using the ATB FUNGUS 3 system. RESULTS: One hundred and twenty six episodes of BSIs occurred in 69 patients between January 31, 2003 and January 31, 2014. The gram-positive bacteria emerged as major pathogens and constituted 48.4% of all pathogens (61/126). The most common bacilli were Enterobacter spp and Enterococcus spp followed by S. aureus. The gram-negative bacteria were relatively sensitive to carbapenems and the gram-positive bacteria were relatively sensitive to glycopeptides and oxazolidone antibiotics. The drug resistance of fungi to amphotericin B, flucytosine, voriconazole and caspofungin was not found. CONCLUSION: In liver transplantation, gram-positive bacteria caused BSls more frequently than gram-negative bacteria. The resistance rate of bacteria to antibiotics was high while the rate was low in fungi.
