Yersinia Enterocolitica IgG ELISA Kit

INTENDED USE

Human Yersinia enterocolitica IgG ELISA kit is a protocol designed for analysing in-vitro amounts of human IgG antibodies to Yersinia enterocolitica (Yersinia-IgG) using samples of serum and plasma. This assay has a minimum analytical sensitivity limit of 1.92 U/ml.

BACKGROUND

Yersinia enterocolitica is a bacillus shaped, gram negative bacterium which belongs to the Enterobacteriaceae family. The genus Yersinia also is made of 11 other species Y. pseudotuberculosis, Y. intermedia, Y. enterocolitica, Y. rohdei, Y. aldovae, Y. bercovieri, Y. kristensenii, Y. mollaretii, Y. ruckeri, Y. pestis and Y. frederiksenii. Enterobacteriaceae have been identified to cause pseudoappendicitis, terminal ileitis, enterocolitis, mesenteric lymphadenitis and acute diarrhea, which can also lead to fatal sepsis if it is spread systemically.

Yersiniosis disease can be caused by Y. enterocolitica infection, predominately an animal-borne disease occurring in humans, cattle, deer, pig and birds. Some of the common test which can be used to diagnose this infection include; observing stool cultures, tube agglutination, joint aspiration in specific cases, colonoscopy, computed tomography scanning imaging studies, enzyme-linked immunosorbent assays and radioimmunoassays.
