Abstract

LUCHS, Adriana et al. Rotavirus G2P[4] and G2P[4]+[6] infections during norovirus gastroenteritis outbreak: summer season 2010, Brazil. Rev. Soc. Bras. Med. Trop. [online]. 2013, vol.46, n.2, pp.227-230. ISSN 0037-8682.  http://dx.doi.org/10.1590/0037-8682-1162-2013.

Introduction

This study aimed to monitor the seasonality of rotavirus infection, and gain insight into the variability of Brazilian strains.

Methods

A total of 28 stool samples were analyzed from 698 revised cases of gastroenteritis during a norovirus outbreak in the summer of 2010 in Guarujá, Brazil. Diagnosis was performed using enzyme-linked immunosorbent assay (ELISA), reverse transcription polymerase chain reaction (RT-PCR), and sequencing.

Results

Rotavirus infection was detected in 17.9% (5/28) of samples; 4 samples were G2P[4] genotype, and one G2P[4]+P[6] genotype. G2 and P[4] sequences showed a genetic relationship to strains from India and Russia, respectively.

Conclusions

The seasonal pattern of rotavirus may be a consequence of human activity apart from climate factors.
