RESUMO

Rotavirus A is the main agent of viral gastroenteritis worldwide and has an important role in morbity and mortality from children up to five years old, in developing countries. This study aimed to detect the agent in children from the birth to one year old. It also aimed to analyze the positivity correlation about the primary infection age group, seasonality, and characterization of the positive samples through of eletropherotyping profile and G and P genotyping. The study analyses samples from 119 children, but only 34 of them were enrolled in the prospective study. The Rotavirus A detection was performed by EIERA and PAGE that allowed the definition of the viral eletropherotypes. The genotyping G and P was performed by RT-nested-PCR. It was observed that four children were positive to Rotavirus A, and three of them were from the prospective study. The infection occurred when they were five and six months old. Another child was infected when it was three months old, but it did not continue in the research. Fifteen of the 119 children had gastroenteritis and 12 were part of the prospective study. Two children had more than one diarrheic episode during the study, including one of the children who was rotavirus positive. One child did not present gastroenteritis even though the sample was positive. The four positive samples were detected by EIERA and two of them were also detected by PAGE. This methodology also characterized these samples as identical with long pattern (bbea). None of the four Rotavirus A positive samples could be genotyped for G or P. The four positive samples were detected in different months of the year (January, March, August and September), therefore, it couldnt be characterized as seasonal. The knowledge acquired throughout this study added to the ones that already exist shall help the undergoing virus prevention strategies worldwide.
