Captivate™ O26

Product Code: CAP003

Immunomagnetic Separation beads for the concentration and isolation of Escherichia coli O26 from food, animal feed, beverages, pharmaceutical or environmental samples.

Captivate™ O26 are magnetisable particles, coated with specific antibody, intended for the concentration and isolation of Escherichia coli O26 from food, animal feed, beverages, pharmaceutical or environmental samples.

Since E. coli O157:H7 was first identified, shiga-toxin producing Escherichia coli (STEC, also referred to as VTEC - verocytotoxin-producing E. coli) of various serotypes have become an increasing concern for public health. Numerous outbreaks have been attributed to STEC serotypes and symptoms may includes bloody or acute diarrhoea, and/or the development in some patients of Haemolytic Ureamic Syndrome (HUS) and Thrombotic Thrombocytopenic Purpura (TTP).

Non-O157 VTEC are associated with the following: fresh meat; ready-to-eat fermented meats (e.g. salami, pepperoni); fresh produce (ready-to eat pre-cut vegetables and sprouted seeds); raw and low heat-treated milk and derived dairy products; and in the hides and fleeces of cattle, sheep and goats.

Conventional isolation methods commonly use enrichment followed by isolation on Rhamnose MacConkey Agar either with or without cefixime and potassium tellurite. However, competing flora may obscure E. coli O26 colonies thereby giving rise to false negative results. Immunomagnetic separation offers a way of rapidly separating E. coli O26 from non target bacteria, resulting in improved rates of isolation.
