Seven major bacterial isolates were obtained and purified. Their 16S rRNA genes were amplified by PCR for sequencing and their identities were determined with homology comparisons. Five of the seven isolates belong to Actinomycetales including Kocuria KD139, Rhodococcus KD140, Rhodococcus KD142, Arthrobacter KD230, and Arthrobacter KD232; one is classified as Bacillus d KD178; and another one as Stenotrophomonas KD237. The phylogenetic tree was also constructed based on the analysis of 16S rRNA gene sequences.

通过对分离菌株的16S rRNA基因序列进行分析，发现其中5株细菌分别属于放线菌目的考克氏菌属(KD139)、红球菌属(KD140和KD142)和节杆菌属(KD230和KD232)， 1株细菌属于杆菌目的芽胞杆菌d属(KD178)，另外1株细菌属于黄色单孢菌目的寡食单胞菌属(KD237)；同时我们构建了系统进化树，确定分离菌株的相对进化地位。

Methods Two arrays of isolates were used to evaluate the reliability of ChromID ESBL. One array contained 285 clinical isolates in which the ESBLs-producing feature was screened by confirmatory tests recommended by Clinical and laboratory Standards Institute. The other array contained 28 enterobacterial isolates with their ESBLs gene and producing enzyme feature being confirmed previously.

用2组肠杆菌科细菌进行评估，一组为285株上海地区检出的临床分离株，这些菌株已用美国临床实验室标准化研究所推荐的确证试验确认了是否产ESBLs，另一组28株产ESBLS肠杆菌科细菌，在以前的研究工作中已确认了这些菌株的产酶特性和ESBLs。

Based on the higher alcohols and lactic acid metabolism theory, a method was developed to low higher alcohols capability Saccharomyces cerevisiae strains by screening high lactic acid dehydrogenization enzyme activity in this study.

本研究对Y1110菌株及其出发菌株、突变等株16株不同来源的酵母菌株进行全基因组RAPD分析，建立并优化了酵母RAPD扩增体系和分型系统，从20条随机引物中筛选出了3条具有较好的扩增多态性，共扩增出34条RAPD谱带，多态性为85.3％；获得了稳定清晰的RAPD指纹图谱。

Results The whole genome of CVB4 jlu06 strain consisted of 7 395 nucleotides encoding 2183 amino acids, which showed high homologies to other CVB4 strains, with the mutations of 10 amino acids. Phylogenetic analysis proved that CVB4 jlu06 strain showed close relationship to HumanCB4 and POLG_CXB4 strains while showed remote relationship to CXB2 strain. Unlike other non-diabetogenic strains, CVB4 jlu06 strain showed common amino acids with diabetogenic strains at 4 sites in 3A region of non-structural protein.

结果 CVB4 jlu06株基因组全长7395个核苷酸，编码2183个氨基酸，与其他CVB4株的同源性较高，且发生了10个氨基酸的变异，与HumanCB4和POLG_CXB4亲缘关系较近，与CXB2亲缘关系较远；CVB4 jlu06株与具有潜在致糖尿病性病毒株，在非结构蛋白3A区4个位点有共同的氨基酸，与非致病毒株不同。

中文摘要：本研究应用标准单因子血清，对四川不同地区规模化猪场分离的16株猪源致病性沙门氏菌进行了血清型鉴定，鉴定出鼠伤寒沙门氏菌(O：1，4，5，12；H1：i；H2：1，2)6株、猪霍乱沙门氏菌(O：6，7；H1：c；H2：1，5)5株、肠炎沙门氏菌(O：1，9，12；H1：g，m；H2：-)3株、德尔俾沙门氏菌(O：1，4，[5]，12；H1：f，g；H2：[1，2])2株。

Analysis is antagonist on the virulence of Erwinia carotovora showed that either the strain culture broth.or the crude enzymes of the strains have the ability to quench the quorum-sensing and attenuate the virulence of Erwinia carotovora.

它们的粗酶液也都具有很强的AHL降解能力，且菌株R1的能力要优于菌株X1。菌株对欧文氏胡萝卜软腐致病菌的拮抗研究表明，无论是菌株X1和R1的菌液本身还是菌株的粗酶液，对致病菌都具有拮抗作用，都能比较明显的抑制软腐病病害。
