    Salmonella Antisera

    SSI Diagnostica has more than 75 years of experience with research and production of Salmonella antisera, and we offer a range of products with strong portfolio breadth and depth to facilitate accurate identification as specified by the Kaufmann-White Scheme.
    Salmonella is often linked with food safety issues, and it is the leading cause of food poisoning. In compromised patients it can even lead to death. Therefore, it is important to get fast and reliable results.
