Abstract

Rotavirus, adenovirus, norovirus and astrovirus are considered to be among the major causes of sporadic cases and outbreaks of acute gastroenteritis globally. Rapid and accurate identification of enteric viruses is still a challenge for the clinical laboratory. Recently, several molecular platforms for the detection of viral enteric pathogens have become available. In this study, the diagnostic accuracy of InGenius Gastrointestinal Viral (GV) Elite Panel, a newly developed one-step multiplex real-time RT-PCR assay simultaneously detecting rotavirus, adenovirus and astrovirus, was evaluated retrospectively analyzing an archival collection of 128 stool samples of children hospitalized with acute gastroenteritis. The overall sensitivity and specificity for the GV assay was 100% and 96.2% for rotavirus, 96.9% and 100% for astrovirus, 100% and 100% for adenovirus, respectively. The InGenius GV assay showed a high concordance with the reference methods and was able to detect all tested genotypes of rotavirus (including G1, G3, G4, G9 and G12P[8] and G2P[4]), adenovirus and astrovirus (AstV-1 and 2). Studies of considerable sample size are required to determine robust Cycle threshold cut-off values to effectively correlate infection to disease. These preliminary results suggest that InGenius GV assay can be recommended as a valuable method for accurate diagnosis of epidemic and sporadic gastroenteritis.
