Intended Use
XLT4 Agar is specifically formulated to be used in conjunction with Tergitol 4 for the effective isolation of non-typhi Salmonella species. This medium is essential in clinical microbiology for detecting these bacteria, particularly in fecal samples.
Product Summary and Explanation
The challenge of overgrowth by non-target bacteria can significantly hinder the recovery of Salmonella species, which is a critical concern during isolation procedures. Common contaminants such as Proteus, Providencia, and Pseudomonas can obscure the presence of Salmonella, complicating diagnosis and analysis.
Introduced by Miller and Tate in 1990, XLT4 Agar was designed to address these issues. The performance of this medium has been extensively validated through research involving fecal-contaminated farm samples, where it demonstrated a notable capability for isolating Salmonella, regardless of high concentrations of competing microorganisms. Subsequent studies revealed that the use of XLT4 Agar considerably enhanced the recovery rates of non-typhoid Salmonella from sources such as poultry and agricultural environments, including drag-swab samples.
Furthermore, XLT4 Agar serves a vital role in clinical settings, allowing healthcare professionals to effectively screen stool specimens for non-typhoid Salmonella, ensuring accurate diagnosis and enhanced patient care.
