Abstract:
Objective To understand the antimicrobial resistance of clinically isolated Enterococcus spp.in Hunan Province.Methods Surveillance data of Enterococcus spp.resistance from member units of Hunan Provincial Anti-microbial Resistance Surveillance System from 2012 to 2021 were collected.Data were cleaned according to a unified method,and WHONET 5.6 software was adopted for statistical analysis.Results From 2012 to 2021,a total of 110 652 non-repetitive Enterococcus spp.strains were included in the analysis,mainly Enterococcus faecalis and Enterococcus faecium,accounting for 46.9%(n=37 774)and 45.9%(n=36 968),respectively,followed by En-terococcus avium(2.5%,n=1 982),Enterococcus gallinarum(1.8%,n=1 428),and Enterococcus casseliflavus(1.5%,n=1 185).The main specimen sources of Enterococcus spp.was urine(51.8%,n=57 350),followed by secretions(9.6%,n=10 660)and bile(8.5%,n=9 377).From 2012 to 2021,the resistance rates of Enteroco-ccus faecalis to ampicillin,teicoplanin,and vancomycin were 5.5%-12.0%,1.3%-2.0%,and 0.6%-1.4%,respectively.The resistance rates of Enterococcus faecium to ampicillin,teicoplanin,and vancomycin were 69.2%-85.0%,1.5%-2.8%,and 0.7%-2.5%,respectively.Except for linezolid and minocycline,the resistance rates of Enterococcus faecium to tested antimicrobial agents were all higher than those of Enterococcus faecalis.The re-sistance rates of Enterococcus faecalis and Enterococcus faecium to vancomycin decreased from 1.4%and 2.1%in 2012 to 0.6%and 0.7%in 2021,respectively,presenting a decreased trend.Conclusion Clinically isolated En-terococcus spp.maintain high antimicrobial susceptibility to vancomycin and teicoplanin.Resistance rates of Entero-coccus faecalis and Enterococcus faecium to vancomycin present decreased trends.
