Utility of two novel multiplexing assays for the detection of gastrointestinal pathogens - a first experience

Springerplus. 2013 Dec;2(1):106. doi: 10.1186/2193-1801-2-106. Epub 2013 Mar 12.


Background: Cause for gastroenteritis range from viral, bacterial to parasitic pathogens. Rapid Multiplexing techniques like ProGastro_SSCS and xTAG_GPP can detect broad panels of pathogens simultaneously. We performed a field test with a total number of 347 stool samples from adult hospitalized patients that were tested with the Luminex xTAG GPP assay; of the 157 samples positively tested for at least one pathogen by xTAG GPP a total number of 30 samples was retested with the ProGastro SSCS assay. Assays were compared to standard routine diagnostics.

Findings: Multiplexing significantly reduced the time to the initial identification of a pathogen. Moreover, multiplexing detected pathogens for which a diagnostic assays was not requested by the physician and thus may be an important tool for avoiding nosocomial outbreaks.

Conclusion: This first frontline approach with these assays approves their utility compared to conventional microbiological methods.
