Yersinia Enterocolitica IgM ELISA Kit
INTENDED USE
Human Yersinia enterocolitica IgM ELISA kit is intended for measuring in-vitro quantitative concentrations of human IgM-class antibodies against Yersinia enterocolitica (Yersinia-IgM) using serum or plasma. This assay has a minimum analytical sensitivity limit of 1.02 U/ml.
BACKGROUND
Yersinia enterocolitica consists of 11 other species: Y. enterocolitica, Y. pseudotuberculosis, Y. kristensenii, Y. mollaretii, Y. aldovae, Y. intermedia, Y. frederiksenii, Y. bercovieri, Y. pestis, Y. ruckeri and Y. rohdei. It is member of the Enterobacteriaceae family and is a gram-negative bacterium which is bacillus shaped. Y. enterocolitica can cause Yersiniosis disease and this is found to be an animal-borne disease which is usually present in human, pig, bird, cattle and deer. It can cause a number of symptoms such as enterocolitis, acute diarrhea, pseudoappendicitis, terminal ileitis and mesenteric lymphadenitis. Methods that have been used to study Yersinia enterocolitica infections include; colonoscopy, tube agglutination, analysing stool cultures, computed tomography scanning imaging studies, radio-immunoassays and enzyme-linked immunosorbent assays.
