Objective  To investigate the change of pathogenic distribution and drug resistance in peritoneal dialysis associated peritonitis (PDAP). Methods  The clinical data of all the patients undergoing continuous ambulatory peritoneal dialysis and suffered from PDAP between January and December in 2014 was retrospectively collected, and the pathogens, drug resistance, outcomes and underlying causes were analyzed. Results  A total of 64 patients had 72 cases of PDAP. Only 36 strains (50.0%) had positive culture results, among which 24 strains (66.7%) were Gram-positive bacteria strains, 7 strains (19.4%) were Gram-negative bacteria strains, and 5 strains (13.9%) were fungi. For Gram-positive bacteria strains, the resistance rates to vancomycin, linezolid and rifampicin were all 0%; the resistance rate to levofloxacin, gentamycin and cefazolin was 14.3%, 26.3% and 50.0%, respectively. For Gram-negative bacteria strains, the resistance rates to amikacin and imipenem were both 0%; the resistant rate to gentamycin, ceftazidime, levofloxacin and ampicillin was 28.6%, 28.6%, 42.9% and 100.0%, respectively. Conclusions  The pathogenic spectrum and drug resistance in PDAP have been markedly changed. Selection of antibiotics should be chosen according to the characteristic of the pathogenic spectrum and drug resistance of each center. Great effort is still needed to improve the culture positive rate of the effluent dialysate and to improve the recovery rate of peritonitis.
