Yersinia Enterocolitica IgA ELISA Kit

  • Created on the 28 September, 2017.


Human Yersinia enterocolitica IgA ELISA kit can be used for determining in-vitro quantitative levels of human IgA class antibodies against Yersinia enterocolitica using plasma or serum samples. This assay has a minimum analytical sensitivity limit of 1.02 U/ml.


Yersinia enterocolitica is a member of the Enterobacteriaceae which is a gram-negative bacillus shaped bacterium. The genus of the Yersinia includes 11 other speices, where are Y. enterocolitica, Y. pseudotuberculosis, Y. pestis, Y. intermedia, Y. bercovieri, Y. frederiksenii, Y. rohdei, Y. mollaretii, Y. ruckeri, Y. kristensenii and Y. aldovae. Y. enterocolitica infection is responsible for causing the disease yersiniosis, this is essentially an animal-borne disease which occurs in humans and many other animals such as pig, cattle, deer and birds. Enterobacteriaceae have been found to cause acute diarrhea, enterocolitis, mesenteric lymphadenitis, pseudoappendicitis and terminal ileitis, if it is spread systemically then it can lead to fatal sepsis. There are many tests which can be carried out in order to diagnose a Yersinia enterocolitica infection. For example, using a stool culture (to confirm presence of pathogen), enzyme-linked immunosorbent assays, tube agglutination, ultrasonography, radioimmunoassays, colonoscopy, computed tomography scanning imaging studies and joint aspiration in specific cases.


The minimum detection sensitivity level of IgA antibodies to  Yersinia enterocolitica using current human Yersinia enterocolitica IgA ELISA kit was 1.02 U/ml. The dynamic range for this assay is 1.0 – 200.0 U/ml.
