Evaluation of the novel DiaSorin LIAISONCampylobacter assay for the rapid detection of Campylobacter spp.

Introduction: Campylobacter spp. infection is one of the leading causes of foodborne diarrhoeal illness in humans worldwide. The purpose of this study was to evaluate the DiaSorin LIAISONCampylobacter assay for human campylobacteriosis diagnosis.

Methodology: A total of 645 stool samples from 640 patients suspected of having gastrointestinal infection were included. A stool culture was simultaneously performed with the DiaSorin LIAISONCampylobacter assay to detect the presence of Campylobacter spp.

Results: Taking the conventional culture to be the perfect gold standard, sensitivity and specificity rates of the DiaSorin LIAISONCampylobacter assay were 100% and 97.7%, respectively; and 99.1% and 98.6%, respectively, when taking the culture to be the imperfect gold standard (Bayesian Model).

Conclusion: This new assay might be a useful tool especially for the screening of negative results.
