DuPont develop faster campylobacter screening test
AUSTRALIA - DuPont Qualicon has released a new test for detecting Campylobacter in poultry that shortens PCR processing time and introduces quantified results by species. This new assay was designed specifically for the BAX® System Q7 instrument and takes advantage of powerful real-time PCR capabilities.

Using enhanced software and multiple probe technology, the BAX® System Q7 differentiates the presence of three species of harmful Campylobacter — C. jejuni, C. coli and C. lari — in a single test. Beyond detection, the system also determines concentration levels and reports the number of colony forming units per milliliter (cfu/mL) for each species in the sample.
The Qualicon BAX® System real-time PCR assay for Campylobacter jejuni/coli/lari enables the Q7 instrument to detect target concentrations as low as 104 cfu/mL, with or without a 24-hour enrichment period. Validated on ready-to-eat poultry and carcass rinses, the system can process up to 96 samples per batch in less than 90 minutes.
"Poultry processors now have a way to quickly find out if pathogenic Campylobacter are present in their products and at what levels," said Kevin Huttman, president of DuPont Qualicon. "Compared with waiting up to five days for culture results, this new BAX® system assay can significantly speed up product release decisions in the poultry industry."
