Full Name: Yersinia Enterocolitica IgA ELISA Kit
Sample Type: Serum, Plasma
Sensitivity: 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 this 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.
Human Yersinia enterocolitica IgA ELISA kit can be used for determining in-vitro levels of human IgA class antibodies against Yersinia enterocolitica (Yersinia-IgA) using plasma or serum samples. This assay has a minimum analytical sensitivity limit of 1.02 U/ml.
All reagents supplied need to be stored at 2 °C – 8 °C, unopened reagents will retain reactivity until expiration date. Do not use reagents beyond this date.
