VALUTAZIONE DI DUE TEST IMMUNOCROMATOGRAFICI PER LA DIAGNOSI DI INFEZIONE DA ROTAVIRUS
2017
Obiettivo dello studio: Valutare l’efficienza diagnostica di due tecniche immunocromatografiche (IC) utilizzate per la ricerca di antigeni di Rotavirus di gruppo A (RVA) nei campioni fecali: CerTest Rotavirus+Adenovirus (Biotec) e Vikia Rota+Adeno (bioMérieux). relazione Entrambe le tecniche IC sono state confrontate con la PCR RealTime, considerata il gold standard per la diagnosi delle enteriti da RVA. I RVA sono i principali agenti eziologici di gastroenterite acuta (AGE) nei bambini al di sotto dei 5 anni di età, con elevati tassi di morbilità e mortalità nelle diverse aree geografiche. Metodi impiegati: Uno studio retrospettivo è stato eseguito su 2096 campioni fecali, raccolti dal 200…
Waterborne Norovirus outbreak at a seaside resort likely originating from municipal water distribution system failure
2018
AbstractIn May 2016 a Norovirus (NoV) gastroenteritis outbreak involved a high school class visiting a seaside resort near Taormina (Mascali, Sicily). Twenty-four students and a teacher were affected and 17 of them showed symptoms on the second day of the journey, while the others got ill within the following 2 days. Symptoms included vomiting, diarrhoea and fever, and 12 students required hospitalisation. Stool samples tested positive for NoV genome by Real-Time polymerase chain reaction assay in all 25 symptomatic subjects. The GII.P2/GII.2 NoV genotype was linked to the outbreak by ORF1/ORF2 sequence analysis. The epidemiological features of the outbreak were consistent with food/waterbo…
Performance analysis of two immunochromatographic assays for the diagnosis of rotavirus infection
2017
Group A rotaviruses (RVAs) are the primary cause of acute gastroenteritis (AGE) in young children worldwide. Several commercial tests including latex agglutination, enzyme-linked assays (ELISA) and immunochromatographic tests (ICT) have been developed for the diagnosis of RVA infection. In the present study, the performance of two commercially available one-step chromatographic immunoassays, CerTest Rotavirus + Adenovirus (Biotec S.L, Zaragoza, Spain) and Vikia Rota-Adeno (bioMerieux SA, Lyon, France) were retrospectively evaluated using Real-time PCR as reference test. Re-testing by Real-time PCR of 2096 stool samples of children hospitalized with AGE previously screened by ICTs (1467 by C…
Performance evaluation of gastrointestinal viral ELIte panel multiplex RT-PCR assay for the diagnosis of rotavirus, adenovirus and astrovirus infecti…
2019
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 ac…
