Thermo Scientific™ Escherichia coli O157 Latex Test
Rapidly confirm E. coli serogroup O157 from colonies cultured on plated media by latex agglutination.
Manufacturer: Thermo Scientific™ DR0620M
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
