实验动物无菌动物生活环境及粪便标本的检测方法 - During the past decade , escherichia coli o157 : h7 has evolved from a clinical novelty to a global public - health concern . the strains of e . coli o157 : h7 was isolated from sporadic diarrheal patient in 1980s , outbreaks caused by e . coli o157 : h7 have been observed in 1999 and 2000 in some areas
我国1987年首次从腹泻病患者粪便标本分离到大肠杆菌o157 ： h7 ， 1999年在某些地区发生了大肠杆菌o157 ： h7引起的暴发， 2000年疫区有扩大的趋势。 - A dna fragment of 348 - bp amplified from the b subunit gene was cut into two dna fragment of 216 and 132 - bp by haelli . endonuclease restriction analysis of the plasmid content with psti showed that strainas with the same result of southern - blot with spesific probe had the different cleavage pattern . the isolated 285 - bpand 348 - bp dna was ligated with plasmid puc18 . the ligation mixture was used to transform e . coli jm109and the transformants were plated on lb agar containing antibiotics . plasmid dna containing cloned genes were used for direct sequencing
提示1999年的疫情由不同的病原菌引起。另外使用针对志贺毒素2及其变种的引物对进行pcr检测、细菌染色体pst和pcr产物的hae 、 ras酶切分析，以及pcr产物的序列分析，发现2000年从江苏省徐州市患者和家畜家禽粪便标本分离的大肠杆菌o157 ： h7菌株仅仅携带slt2vha基因。 - We found that sit variant gene ( slt2vha ) was identified in strains e . coli o157 : h7 isolated from patients and dung beetles 2000 in xuzhou city , jiangsu province . the primers used for stx2 variant analysis are shown in tablel . genomic dna restriction fragments digested by pstiwere sonthern - blotted and hybridized with an stx2 - specific dna probe . the probe was prepared fromed a 285 - bp pcr productof the strain 882364 stx2 gene obtained by using the specific primer pair ( tablel )
2000年在江苏省徐州市铜山县腹泻病患者的粪便标本分离的10株产生志贺毒素的菌株以及从蜣螂肠道分离到的4株产生志贺毒素的大肠杆菌o157 ： h7 ，属于另两个pfge型，和1986 、 1987 、 1988年在徐州市腹泻病患者的粪便标本分离的菌株pfge图谱不同。
