| 摘 要： | 为了解河南省某地区社区健康人源及动物(鸡、猪)源肠球菌种属分布及对多种抗菌药物的耐受情况,以及研究不同来源肠球菌的流行分布和抗菌药物耐药表型特点,本试验应用肠球菌选择性培养基对220份人源及动物源粪便样本进行肠球菌的分离培养,并对分离菌株采用16S rDNA序列分析结合API生化板条进行种属鉴定,纸片扩散法对分离肠球菌进行9种抗菌药物的敏感性检测.肠球菌分离及鉴定结果显示肠球菌总分离率、粪肠球菌分离率及屎肠球菌分离率在人源、鸡源、猪源3种来源间均差异显著(P<0.05):肠球菌总分离率为70.91%(156/220),猪源肠球菌分离率最高(86.00%),人源肠球菌分离率最低(62.63%),且人源与猪源肠球菌分离率差异显著(P<0.018);人源粪便样本中分离率最高的为屎肠球菌(31.36%),鸡源、猪源肠球菌中粪肠球菌分离率最高,分别为28.17%和32.00%.抗菌药物敏感性结果显示肠球菌对多种药物的耐药率在人源、鸡源、猪源3种来源间差异显著(P<0.05),且3种来源肠球菌的多药耐药率差异有统计学意义(P<0.05).人源肠球菌对红霉素(69.35%)、环丙沙星(37.10%)、氨苄西林(19.35%)等抗菌药物耐药率较其他来源的肠球菌要高;鸡源肠球菌对四环素(88.24%)、氟苯尼考(11.76%)、氯霉素(21.57%)等抗菌药物耐药率较其他来源的肠球菌要高;猪源肠球菌对抗菌药物耐药率总体较低,且其多药耐药率(7.84%)也低于人源(35.48%)及鸡源肠球菌(30.19%).提示,健康人及动物粪便样本中肠球菌种属分布不同及对抗菌药物耐药率有差别,并对多种常见抗菌药物耐药率较高,有关部门应加强社区人群及动物等非临床来源肠球菌耐药检查、监测,进而更好的了解中国耐药肠球菌的流行现状,更有效的控制耐药肠球菌的传播.

| Abstract: | The assay was aimed to evaluate the differences of prevalence and drug resistance of Enterococcus species among human, broilers and swines in Henan province, China. Totally 220 stool samples were collected, and identified by 16S rDNA sequence analysis and the Rapid ID 20 Strep System. There were significant differences among the total isolation rate of Enterococcus, isolation rate of E.faecalis, isolation rate of E.faecium in 3 different origins (P<0.05).A total of 156 (70.91%) Enterococcus spp. isolates were recovered. The isolation rate of Enterococcus from swine origin was the highest (86.00%), while human origin was the lowest (62.63%), There were significant differences between the isolation rates of swine and human origns (P<0.018). The most predominant specie was E.faecium (31.36%) in human, while in broilers and swines were E.faecalis (28.17% and 32.00%, respectively). All isolates were sensitive to vancomycin and teicoplanin. The resistant rate of many multidrug-resistant (MDR) of the isolates from human, broilers and swines were statistically significant (P<0.05).The resistant rates of isolates from human origin Enterococcus spp.to erythromycin (69.35%), ciprofloxacin (37.10%) and ampicilin (19.35%) were higher than those from broiler origin and swine origin. The isolates resistant rates to tetracycline (88.24%), florfenicol (11.76%) and chloramphenicol (21.57%) from broiler origin Enterococcus spp. were higher than those from the other two origins, respectively. The MDR rates of human (35.48%) and broiler (30.19%) origins isolates were higher than swine origin (7.84%). The observation in this study suggested that the prevalence and drug resistance of Enterococcus spp. from human, broilers and swines in Henan province were different, and the MDR isolates were prevalent in various origins Enterococcus. More attention should be given on investigation and research of the resistance of Enterococcus among human and animals to better understand the epidemic of the antidrug-resistant Enterococcus and minimize the spread of it effectively. |
