What test will differentiate between Salmonella enteridis and Shigella sonnei?
To differentiate between Salmonella enteritidis and Shigella sonnei, the triple sugar iron (TSI) agar test can be used. Salmonella enteritidis typically produces hydrogen sulfide (H2S), resulting in black colonies on TSI agar, while Shigella sonnei does not produce H2S and will not change the color of the agar. Additionally, biochemical tests such as urease and indole tests can further help distinguish between the two, as Shigella sonnei is urease negative and indole positive, while Salmonella enteritidis is urease negative and indole negative.
