摘要:
分析美国1996—2016 年间人源、动物源和肉类中主要病原菌类别及耐药性,探讨抗菌药使用量与耐药性的关联性,并对我国抗菌药的使用及人源菌株耐药性进行分析,比较两国间在抗菌药使用和细菌耐药性方面的差异。在美国近19 万株病原菌中,29%来源于病人,71%来源于动物及其制品,其中,在动物源菌株中不同动物的比例为鸡41%、牛13%、火鸡9%、猪8%;在动物样本和患病病人样本中检出率最高的均是沙门菌(分别占45%和66%),在畜禽肉样品中检出率最高的是肠球菌属(42%),说明在美国沙门菌是动物和人致病或携带的主要食源性病菌。从我国2016 年人源性致病菌数据来看,以致病性大肠埃希菌和金黄色葡萄球菌为主。耐药性数据显示,美国主要使用的6 类抗生素和我国主要使用的4 类抗生素皆存在较高水平的耐药率,两国较少使用的氨基糖苷类药物也出现高耐药率。但由于我国缺乏长期而系统的耐药性监测数据,因而这种比较显得牵强。因此,建议卫生部门、农业部门和食品药品监督管理机构整合资源,加强对动物养殖、肉类食品、临床病人以及相关环境中耐药菌株的分布与耐药性进行系统监测和数据整合,及时调整用药相关政策,以便从源头上控制细菌耐药性的产生,并在食物链中遏制耐药致病菌、耐药菌和耐药基因的传播,保障国民健康和公共卫生安全。

Abstract:
Systemic analyses were conducted on the major groups of pathogenic bacteria and antimicrobial resistance patterns during 1996—2016 from the dataset of the USA National Antimicrobial Resistance Monitoring System. Potential links between consumption of antimicrobials and patterns of antimicrobial resistance were discussed. Bacterial pathogens of patients and antimicrobial resistance data in 2016 from CHINET (China Antimicrobial Resistance Surveillance Network) were also retrieved for comparative purpose and correlated with consumption of antimicrobials in China. Of 190 365 strains in the USA database, 29% were from human patients, and 71% were from animals and their meat samples. Percentage of isolates from animals and meat was further attributed from high to low as follows: chicken 41%, cattle 13%, turkey 9% and pig 8%. The pathogen of highest prevalence in animals and human patients was Salmonella (45% and 66% , respectively). Animal meat was dominated by Enterococcus spp. (42%). Salmonella was the main pathogen in animals and humans in the United States. Of the pathogens from human patients in 2016 in China, pathogenic Escherichia coli and Staphylococcus aureus were predominant. Resistance data suggested that high resistance was seen in commonly used drugs in six classes of antimicrobials in the United States and four classes of antimicrobials in China. High resistance rate was also observed in aminoglycosides that were not commonly used in both countries. Nevertheless, such comparison appears to be farfetched due to lack of long-term systemic surveillance data in China. Integration of resources from the national health departments, agricultural departments and food administrations, therefore, is highly recommended for coordinated efforts to monitor resistant bacterial species via food-chain from food animals, meats, human patients. Such data could be linked with the use of antimicrobials in human clinical settings and food animal for policy makers to propose guidelines for prudent or restricted use of certain antimicrobials. This would eventually safeguard the general public from threats of resistant pathogens by decreasing antimicrobial resistant pathogens, antimicrobial bacteria and antimicrobial resistant genes via food-chain.
