Abstract:
Objective To understand the distribution and antimicrobial resistance of pathogenic bacteria isolated from patients in the department of infectious diseases in Xiangya Hospital.Methods The distribution and antimicrobial susceptibility testing results of pathogenic bacteria isolated from patients in this department in 2011 -2015 were analyzed retrospectively.Results A total of 560 strains were isolated during 5 years,of which gram-posi-tive bacteria and gram-negative bacteria accounted for 44.1 % (n =247)and 55.9%(n =313)respectively.69.8%(81/116)of coagulase-negative staphylococcus and 24.3%(9/37)of Staphylococcus aureus were methicillin-resistant (MRCNS,MRSA)respectively.Enterococcus was highly susceptible to vancomycin,linezolid,and phosphonomy-cin (>81 %).Enterobacteriaceae remained highly susceptible to carbapenems (88.9%-100.0%),and was suscep-tible to amikacin,cefoperazone/sulbactam,and piperacillin/tazobactam (>84%).Acinetobacter baumannii was the major isolated multidrug-resistant organism (MDRO),isolation rate of imipenem-resistant Acinetobacter baumannii increased from 50.0% in 2011 to 77.8% in 2015,its resistance rate to imipenem was 64.9%.Conclusion The majority of clinically isolated pathogenic bacteria from this department is gram-negative bacilli,and detection rate of MDROs showed an upward trend;antimicrobial agents should be chosen according to distribution and antimicrobial resistance of pathogenic bacteria.
