为了解2013-2017年间广东省猪源葡萄球菌的耐药情况及多重耐药基因cfr的流行现状,采集生猪养殖场和交易市场猪鼻腔拭子分离葡萄球菌,采用琼脂稀释法测定分离菌株对14种抗菌药物的敏感性,并用PCR检测mecA和cfr基因的携带情况。结果显示,在采集的4099份样品中分离到葡萄球菌1485株,其中金黄色葡萄球菌173株。猪源葡萄球菌对红霉素、四环素、泰妙菌素、克林霉素、沃尼妙林和氟苯尼考耐药严重,耐药率分别为91.0%、90.2%、87.7%、84.6%、84.6%及82.0%,对利福平和利奈唑胺相对敏感,未发现万古霉素耐药菌株;庆大霉素、四环素、红霉素和环丙沙星的耐药率呈现逐年上升的趋势。在1485株葡萄球菌中,mecA和cfr的检出率分别为39.9%和12.3%。cfr阳性菌株常携带多种耐药基因,cfr基因的遗传背景也呈现多样化。结果表明,广东省猪源葡萄球菌的耐药情况严重,cfr的检出率高,应加强养殖业中抗菌药物的规范和合理使用,减缓耐药性的产生和传播。  相似文献

日本环境友好型生活方式的立法培育经验及对我国的启示   总被引:1,自引:0,他引:1  
促进公众形成环境友好型的生活方式,是建设环境友好型社会的必然要求。环境资源问题在中国和日本均已成为制约经济和社会进一步发展的瓶颈。日本在培育国民形成环境友好型生活方式方面取得了很好的成效。从法律上来看,该国的经验在于制定了完备的立法体系,并在责任分配、教育说服、公众行为的引导和综合性法律调整四个方面规定了切实有效的法律制度。我国的相关立法不完善,制度的建设也存在欠缺。因此,在技术层面上定向地借鉴日本的成熟经验,按照我国的经济基础、环境状况、环境文化和国民生活方式等基本国情,逐步完善相关的立法和制度是必要的。实践证明也是可行和有效的。  相似文献

The horizontal displacement of the human body resulting from fatal fall from a height is an important variable commonly used to inversely determine the cause or identify other forensic aspects of the fall. When examining the horizontal displacement, the wind effect is generally ignored. This technical note reports analytical modeling of the falling process, utilizing previous measurements of wind force acting on the human body, for determining the functional relationship between the wind speed and the horizontal displacement in the falling process. The result reveals that it does not take extremely rare wind conditions to cause a considerable shift of the human body, highlighting the importance to consider wind as a factor in investigations of fatal falls.  相似文献

Species identification of necrophagous insects found on a dead body is an essential key in applying medicolegal entomology to the estimation of postmortem interval (PMI). Due to limited morphological identification of insect evidence, several studies have identified species using molecular information such as DNA markers. While considerable cytochrome c oxidase subunit I (COI) gene sequence data of necrophagous fly species have been collected and annotated, those of necrophagous beetle species have not. Since necrophagous beetles such as Dermestes species have a larval period longer than that of flies, beetles are useful in even the late decomposition phase in estimating minimum PMI. To obtain the full-length COI gene sequences of six Dermestes species collected from South Korea, we designed primers for polymerase chain reaction amplification and sequencing. The obtained full COI nucleotide sequences were used for performing phylogenic analysis and comparison with previously reported sequences. The results demonstrated that the COI gene sequences could be used to identify forensically important Dermestes species in South Korea.  相似文献

This study proposed and confirmed three ways in which college students can perceive shared agency and two ways in which they can perceive non-shared agency with parents when pursuing educational goals in college. Differences and similarities were examined among participants from four ethnic backgrounds (N = 515; 67% female): East Asian American, Southeast Asian American, Filipino/Pacific Islander American, and European American. Results indicated that Asian American youth reported higher levels of non-shared agency with parents (i.e., parental directing and noninvolvement), lower levels of shared agency (i.e., parental accommodation, support, or collaboration), and poorer college adjustment compared to European Americans. However, ethnic similarities were found whereby perceived shared agency in education with parents was associated with college adjustment. Multiple mediation analyses also indicated that our model of shared and non-shared agency with parents explained differences in college adjustment between Asian and European Americans, though more strongly for comparisons between European and East Asian Americans. Our results suggest that parents continue to be important in the education of older youth but that continued directing of youth’s education in college can be maladaptive.  相似文献

This article investigates South Korean views on how to deal with the two major security issues regarding North Korea: its nuclear threat and regime instability. In this Special Section, the article analyzes the ongoing debate in South Korea over the government's policy toward North Korea in regard to these two issues. It argues that uncertainties about these two major issues are shaping the regional order in East Asia. In particular, the different levels of cooperation between South Korea and the United States may affect the regional security order in East Asia. In analyzing policy options available to South Korea, the riskiest option would be to employ early preemptive attacks and accelerate the collapse of North Korea given the security dilemma-driven action?reaction in East Asia. Given that the role of China has become the most crucial factor in dealing with North Korea, the most promising strategy would be to reinforce guarantees of extended nuclear deterrence and prompt a soft-landing unification.  相似文献
