CDIA^TM Human Shigella Dysenteriae Rapid test (DTSXYZ5)

General Description

Clinical syndromes in humans caused by infection with Shigella are divided into S. dysenteriae, S. flexneri, S. boydii and S. sonnei, and a range of clinical syndromes, including diarrhoeal disease, fever and stomach cramps. Shigellosis are associated with poor sanitation, contaminated food and water, and crowded living conditions and usually resolves in 5 to 7 days. The predominant serogroups of Shigella are particularly common and it causes recurrent problems in settings where hygiene is poor and can sometimes sweep through entire communities. Shigella Dysenteriae Rapid test kit provides a rapid detection of Shigella dysenteriae directly from the fecal samples.

Principle

The Shigella Dysenteriae Rapid test is a qualitative lateral flow immunoassay for the detection of Shigella dysenteriae antigen in fecal samples. The membrane is pre-coated with monoclonal antibodies against Shigella dysenteriae antigens on the test line region. During testing, the reacts with the particle coated with anti-Shigella dysenteriae antibodies which was pre-dried on the strip. The mixture moves upward on the membrane by capillary action. In the case of a positive result the specific antibodies present on the membrane will react with the mixture conjugate and generate a coloured line. A green coloured line always appears in the control line and serves as verification that sufficient volume was added, that proper flow was obtained and as an internal control for the reagents.
