Product Summary and Explanation
Overgrowth of nuisance or contaminating organisms can be a major problem when recovery of a specific organism or species is desired. This is particularly true of Salmonella isolation media where overgrowth of Proteus, Providencia and Pseudomonas can dramatically interfere with the detection and isolation of Salmonella.
In 1990, Miller and Tate described a new medium, XLT4 Agar, for isolating Salmonella. Miller and Tate evaluated the sensitivity of the medium by detecting and isolating Salmonella using fecal-contaminated farm samples containing high numbers of competing bacteria. In proceeding studies, Miller and Tate4 reported that XLT4 Agar significantly improved the recovery of non-typhi Salmonella from chicken and farm environmental drag-swab samples. XLT4 Agar can be used clinically to screen stool samples for non-typhoid Salmonella.
