Use this rapid latex agglutination test for detection and presumptive serogrouping of Salmonella
from Selenite Broth and solid culture media. Wellcolex Color Salmonella can also be used for the presumptive identification of Salmonella
serogroups A, B, C, D, E, and G, and the Vi antigen using just two reagents.
- Identifies major groups of Salmonella
- Utilizes advanced color technology for clear, easy-to-read species and/or serogroup identification
- Provides accurate, reliable results in less than three minutes
- Quickly eliminates negative samples when used as primary culture screening method
To perform Wellcolex Color Salmonella, a sample from a Selenite F broth culture (18 to 24 hours incubation) or a suspension of bacteria from solid agar is reacted with two test reagents, consisting of a mixture of suspensions of red, blue and green latex particles, each of which is coated with antibody specific for different Salmonella serogroups.
In the presence of homologous antigen one of the colors in the mixture will agglutinate, and the identity of the antigen is indicated by the color of the aggregated particles with a contrasting change in the color of the background. Each combination is easily distinguished from the others and from a negative result in which the particles remain in smooth greyâ€‘brown suspension, and the occasional nonâ€‘specific result in which all the particles agglutinate into greyâ€‘brown aggregates against a cleared background.
