河北省各地各有关部门坚决落实党中央、国务院有关非洲猪瘟防控的决策部署,各负其责、通力配合,积极优化防控策略,明确"三式管理(养殖企业"密罐式"管理、屠宰企业"高压式"管理、官方兽医"问责式"管理)、三大行动(大清理大清洗大消毒行动、生猪运输车辆全程监管行动、养殖屠宰企业建档升级行动)"的常态化防控措施,细化工作内容、时间安排、工作方式,不断创新完善养殖、屠宰、运输及无害化处理等环节的非洲猪瘟防控全程监管工作机制,全面打好非洲猪瘟疫情持久战,全省非洲猪瘟等重大动物疫情形势稳定,有效保障了全省生猪生产和市场稳定供应.

This study was conducted to identify the species origin of 91 samples of frozen fish products and highly processed, pre-packaged fish products collected from supermarkets using DNA barcoding technique based on homologous sequence analysis of the COI and 16S rRNA genes.The results confirmed that both COI and 16S rRNA gene sequencing were useful for species authentication of fish products. The species origin of 66 of 79 (83.54%) frozen fish products and 7 of 12 (58.33%) highly processed, pre-packaged fish products was consistent with the product claims, which indicated that some problems such as mislabeling and ambiguous ingredient designation of fish products existed in the fish market. This research can provide technical support for the supervisory authorities concerned .

档案的收集与整理是档案管理的基础性工作,一个档案管理机构的管理水平如何,最主要的是看其库存档案保管质量和库存档案利用价值的高低.提高档案的管理水平,就必须首先做到高水准的收集与整理工作. 1 档案材料的收集 1.1档案管理的重要性.档案工作的特点是“做起来不起眼,整起来很麻烦,用起来离不开,时间长了用起来更重要”.档案工作的性质决定了干这一行的人要具有踏实肯干、无私奉献的精神.

【OBJECTIVE】The resistance to metalaxyl of Phytophthora infestans was assessed in the four provinces of main potato production and cross-resistances of metalaxyl with propamocarb and cymoxanil were also examined;【METHOD】The resistance to metalaxyl of P.infestans was assessed by an in vitro radical growth assay on fungicide-amended media and cross-resistances of metalaxyl with propamocarb and cymoxanil were estimated through comparison of virulence of three fungicides;【RESULTS】Metalaxyl-resistant isolates generally occurred in three provinces of Sichuan,Hebei and Heilongjiang provinces except Yunnan and the frequencies of metalaxyl-resistant strains were 16.7%,24.0% and 100% in Sichuan,Hebei and Heilongjiang provinces,respectively.Tests of virulence of three fungicides shown that virulences of cymoxanil to metalaxyl-resistant and sensitive isolates were very high and virulences of propamocarb to these two kinds of isolates were very low,which indicating cross-resistances of metalaxyl with propamocarb and cymoxanil did not exist;【CONCLUSION】Metalaxyl-resistant isolates of P.infestans generally occurred in China.Cymoxanil could substitute metalaxyl for controlling potato late blight because it was highly virulent to P.infestans and did not exist cross-resistances with metalaxyl.
