Thermo Fisher, DR0620M, Escherichia coli O157 Latex Test

Name: Escherichia coli O157 Latex Test
Brand: Thermo Fisher
SKU: DR0620M

Quantity: 100 Tests/Kit, Unit Size: Each, A latex agglutination test for the identification of E. coli serogroup O157. Certain strains of Escherichia coli have been implicated in cases of haemorrhagic colitis (HC) and haemolytic ureamic syndrome (HUS). It has been shown that these strains produce a vero-cytotoxin (VT). The E coli serotype most frequently isolated from HC and HUScases is O157:H7. Isolation of this serotype from a diarrhoeal stool particularly with the presence of blood is indicat

Description

Quantity: 100 Tests/Kit
Unit Size: Each
Use this dry latex test designed to demonstrate by slide agglutination E. coli strains possessing the O157 serogroup antigen. The test is best used in conjunction with Sorbitol MacConkey Agar. E. coli O157:H7 strains do not ferment sorbitol and, therefore, give colorless colonies on this medium. The majority of E. coli isolates do ferment sorbitol and give characteristic pink colonies. Sorbitol MacConkey Agar should be used as the primary screen. Non-sorbitol fermenting colonies can then be tested with the latex reagents to determine whether the isolate belongs to the O157 serogroup and, therefore, a potential verotoxin-producing strain.
• Pre-dispensed reagents eliminate extra steps for faster time to result
• Room temperature storage for up to two years simplifies inventory
• Blue latex particles are sensitized with reactive (positive) and non-reactive (negative) antibodies and dried onto reaction cards for convenience Not all products are available for sale in all territories.

Question: How many tests are included?

Answer:The kit provides 100 tests.

Application Note

The Escherichia coli O157 Latex Test is a rapid slide-agglutination assay for confirmation of E. coli strains that express the O157 serogroup antigen. Colonies are first cultured on appropriate plated media, then mixed with the latex reagents to observe visible agglutination. The method is useful for screening colonies suspected of belonging to the O157 serogroup, including isolates recovered during investigation of hemorrhagic colitis and related food or clinical microbiology workflows. This kit provides 100 tests and is commonly paired with selective culture media such as Sorbitol MacConkey Agar during the identification process. The assay identifies the O157 antigen and should be integrated with the laboratory’s broader confirmation scheme when strain characterization beyond serogroup is required. The latex format provides a simple, rapid confirmation step without specialized instrumentation.
