Serum Escherichia coli, 2 ml, DENKA SEIKEN, Japan

Escherichia coli is a group of gram-negative sticks belonging to the Enterobacteriaceae family and is considered one of the bacteria of the normal intestinal microflora of humans. Their serological types are determined by a combination of a somatic antigen (O group: O1-O173) and flagella (H type: H1-H56) antigens.

E. coli causing intestinal infectious diseases, including diarrhea, acute gastritis or colitis, are pathogenic E. coli and are divided into the following 4 groups according to differences in pathogenicity; enteropathogenic E. coli (EPEC), enteroinvasive E. coli (EIEC), enterotoxigenic E. coli (ETEC), and enterohemorrhagic E coli (EHEC). Although the identification of pathogenic E. coli requires testing their pathogenicity, pathogenic E. coli often have specific serotypes; consequently, the definition of serogroup and serotype is necessary for the screening of pathogenic E. coli.

O and H serum are liquid products containing specific agglutinins for E. coli serotyping. O-group of sera is prepared by hyperimination of healthy pigs (polyvalent serums) or healthy rabbits (monovalent serums) with reference strains of microorganisms of each serotype, inactivated by formalin, heated at 56 ° C for 30 minutes. Cross-agglutinins are removed by absorption and antiseptic filtration. For the preparation of H-sera, healthy rabbits were immunized with E. coli flagella. Group O-serums are used for the O-serotipation test by agglutination on the glass, and H-sera for H-serotyping by agglutination in the test tubes.

 NECESSARY USE

Determination of serotypesE. coli

 PRINCIPLE OF DEFINITION

When this reagent is mixed with E.coliis strain with an antigen corresponding to the reagent, the antigen-antibody reaction causes agglutination formation. The reaction is taken into account macroscopically to determine each serotype.Delivery time: 5 days
