Description

Nucleotide to the O-antigen-specific of Shigella bogdii 8 types and intestinal bacteria O143
Technical field
The present invention relates to the complete nucleotide sequence of control O-antigen synthetic gene cluster in Shigella bogdii 8 types (Shigella boydii 8), particularly relate in Shigella bogdii 8 types oligonucleotide in the control O-antigen synthetic gene cluster, can utilize these oligonucleotide of O-antigen-specific Shigella bogdii 8 types and the intestinal bacteria O143 (Escherichia coliO143) in human body and the environment and identify O-antigen in these pathogenic bacterium quickly and accurately.
Background technology
Shigellae is the pathogenic bacterium that grow up along with the human evolution, can attack colon film epithelial cell, causes self limiting pyogenic infection focus, causes human bacillary dysentery.Human have higher susceptibility to Shigellae, only need be less than the infection that ten bacterium just can cause the people, children and adult easy infection, particularly children, easily cause acute poisoning dysentery, and the O-antigen of Shigellae is the one of the main reasons that Shigellae causes disease.
O-antigen is the O specific polysaccharide composition in the gram negative bacterium lipopolysaccharides, and it is made up of many multiple oligosaccharide unit.The antigenic building-up process of O-is studied clearlyer: by glycosyltransferase nucleoside diphosphate monose is transferred on the fat molecule that is fixed on the cell inner membrance earlier, then in the inboard synthesis of oligose unit of inner membrance, the antigenic oligosaccharide unit of O-is transferred to the inner membrance outside by the transhipment enzyme again, then aggregate into polysaccharide by polysaccharase, be connected to again and form lipopolysaccharide molecule [Whitfield, C. (1995) " Biosynthesis of lipopolysaccharide Oantigens " .Trends in Microbiology.3:178-185 on the glycolipid molecule; Schnaitman, C.A.andJ.D.Klena. (1993) " Genetics of lipopolysaccharide biosynthesis inentericbacteria " .Microbiological Reviews, 57 (3): 655-682].Coding is responsible for the generally adjacent arrangement on karyomit(e) of gene of all enzyme molecules of O-antigen synthetic, form a gene cluster [Reeves, P.R., et al. (1996) " Bacterial polysaccharide synthesis and genenomenclature " Trends in Microbiology, 4:495-503].In Shigellae, intestinal bacteria and Salmonellas, O-antigen gene [Lei Wang.et al (2001) " Sequence analysis of four Shigella boydii O-antigen loci:implicationfor Escherichia coli and Shigella relat ionships " .Infection andImmunity, 11:6923-6930 bunch between galF and gnd gene; Lei Wang and Peter Reeves (2000) " TheEscherichia coli O111 and Salmonella enterica O35 gene clusters:geneclusters encoding the same colitose-containing O ant igen are highlyconserved " .Journal of Bacteriology.182:5256-5261].The O-antigen gene bunch contains three genoids: sugared synthesis path gene, glycosyltransferase gene, oligosaccharide unit treatment gene.The required nucleoside diphosphate monose of enzymic synthesis O-antigen of wherein sugared synthesis path genes encoding; Thereby the enzyme of glycosyltransferase gene coding forwards nucleoside diphosphate monose and other molecule to and makes monose aggregate into oligosaccharide unit on the monose; The oligosaccharide unit treatment gene comprises transhipment enzyme gene and pol gene, and they transfer to the bacterium inner membrance outside with oligosaccharide unit, and repolymerization becomes polysaccharide.Glycosyltransferase gene and oligosaccharide unit treatment gene only are present in the gene cluster of carrying these genes.The difference of monose in the O-antigen, between monose between the difference of link button and the oligosaccharide unit difference of link button constituted the antigenic diversity of O-, and link button between synthetic, the monose of monose and the link button between the oligosaccharide unit are by the Gene Handling in the O-antigen gene bunch, so the O-antigen gene bunch has determined O-antigenic synthetic, has also determined the antigenic diversity of O-.
Because O-antigen is extremely strong antigen, be one of important paathogenic factor of Shigellae, it has extremely strong diversity again simultaneously, and this enlightens us can study a kind of Shigellae and good, highly sensitive method of the antigenic specificity of O-thereof of detecting quickly and accurately.With surperficial polysaccharide is that the serology immune response of target has been used to somatotype and the evaluation to bacterium always since the thirties in last century, is unique means of identifying pathogenic bacterium.This diagnostic method needs a large amount of antiserum(antisera)s, and the antiserum(antisera) general classes is incomplete, quantity not sufficient, and also there are some difficulties in a large amount of antiserum(antisera)s in preparation with in storing.On the other hand this method length consuming time, sensitivity is low, loss is high, poor accuracy, so, generally believe that now this traditional serology detection method will be that the modern molecular biology method replaces.1993, Luk, J.M.C et.al has identified the O-antigen [Luk of Salmonellas with the specific nucleotide sequence of Salmonellas (S.enterica) O-antigen gene bunch by PCR method, J.M.C.et.al. (1993) " Selective amplification ofabequose and paratose synthase genes (rfb) by polymerase chain reactionfor identification of S.enterica major serogroups (A; B; C2; andD) ", J.Clin.Microbiol.31:2118-2123].Luk, the method for et.al is with corresponding to Salmonellas serotype E 1, D1 obtains the oligonucleotide special to the Salmonellas of different serotypes after the nucleotide sequence of the CDP-abequose in the A, the O-antigen of B and C2 and the synthetic gene of CDP-tyvelose is arranged.1996, Paton, the A.W et.al serotype [" Molecularmicrobiological investigation of an outbreak of Hemolytic-UremicSyndrome caused by dry fermented sausage contaminated with Shiga-liketoxin producing Escherichia oli " .J.Clin.Microbiol.34:1622-1627] of having identified the toxogenic E.coli O111 of a strain at the oligonucleotide that comes from the wbdI gene of the O-antigen-specific of E.coli O111, but afterwards studies show that Paton, the usefulness of A.W et.al comes from the oligonucleotide of wbdI gene and identifies that the method for the serotype of E.coli O111 has false positive results to occur.Bastin D.A.and Reeves, P.R. think, this is because the wbdI gene is sugared synthesis path gene [the Bast in D.A.andReeves of a supposition, P.R. (1995) Sequence and analysis of the O antigen gene (rfb) cluster of Escherichia coli O111.Gene 164:17-23], and have this sugar in the antigenic structure of the O-of other bacterium, so sugared synthesis path gene is not a high special for O-antigen yet.
Shigellae has 46 kinds of serotypes, intestinal bacteria have 166 kinds of different O-antigens, the two sibship is very near, and it is that intestinal bacteria and Shigellae are total that 12 kinds of O-antigens are arranged, wherein Shigella bogdii 8 types just have identical O-antigen [Ewing with intestinal bacteria O143, W.H. (1986) " Edwardsand Ewing ' s identification of the Enterobacteriaceae " .ElsevierScience Publishers, Amsterdam, The Netherlands; T.cheasty, et al. (1983) " Antigenic relationships between the enteroinvasive Escherichiacoli antigens O28ac; O112ac; O124, O136, O143; O144; O152and O164andShigella O antigens " J.clin Microbiol, 17 (4): 681-684], traditional serotype method can not be distinguished them.
