Abstract:Objective To understand the distribution and drug resistance of pathogenic bacteria in Chongzuo City, and to grasp the situation of bacterial resistance change in this region, and provide a basis for the rational application of antibacterial drugs. Methods Data of clinical isolation pathogenic bacteria composition and drug resistance in 7 general hospitals from 2014 to 2016 were analysed. A total of 172 367 samples of pathogenic microorganisms were collected, in which 18 256 strains of bacteria were isolated. The paper method or minimal inhibitory concentration (MIC). method were used to determine the sensitivity of antibiotics. The test and judgment standards were applied according to the Clinical & Laboratory Standards Institute (CLSI) standards of each year. WHONET5.6 software was used for statistical analysis of data. Results From 2014 to 2016, Gram-positive bacteria accounted for 24.3% and Gram-negative bacteria 75.7% of clinical isolates pathogenic bacteria in Chongzuo area. The Gram-positine Racteria ranked first in the isolated pathogens from 2014 to 2016 were Staphylococcus aures, and the second were Staphlococcus epidermidis; the Gram-negatiue becteria in the isolated pathogens ranked in the top five were Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Acinetobacter baumannii, Enterobacter cloacea. From 2014 to 2016, the detection rates of methicillin-resistant Staphylococcus aureus (MRSA) were 18.3%, 24.9%, 26.0% respectively, vancomycin-resistant Enterococcus faecalis were 2.8%, 0.0%, 0.0% respectively, and vancomycin-resistant Enterococcus faecium was not detected. From 2014 to 2016, the detection rates of penicillin- resistant Streptococcus pneumoniae (PRSP) and erythromycin-resistant Streptococcus pneumoniae (ERSP) were 67.6%, 68.9%, 68.2% and 92.3%, 96.5% 94.4%, respectively. The third generation of cephalosporins-, carbapenems- and quinolones-resistant Escherichia coli were 51.1%, 47.8%4, 5.2%; 0.9%, 0.7%, 0.4%; and 42.2%, 44.6%, 40.9%, respectively. The resistant rates of Klebsiella pneumoniae to the third generation of cephalosporins were 31.0%, 26.6%, 23.6%, and Klebsiella pneumoniae to carbapenems were 0.7%, 2.0%, 1.8%. The detection rates of carbapenems-resistant Pseudomonas aeruginosa and carbapenems-resistant Acinetobacter baumannii were 6.5%, 14.4%, 11.9% and 25.4%, 42.3%, 38.6% respectively. Conclusion It is serious of bacteria resistant to antibiotics in Chongzuo City. From 2014 to 2016, the detection rate of MRSA shows an increase trend, PRSP was higher than the average levels of Guangxi and China, and the drug resistance rate of carbapenems increased rapidly. Management of antimicrobial application and monitoring of bacterial resistance should be strengthened.
