Abstract

With the rapid dissemination of Zika virus (ZIKV) in the Tropical world and its entry in Brazil, a rapid strategy with interaction of different scientific areas is necessary in order to understand better the infection pathogenesis. A significant number of studies performed in Brazil are destined towards understanding ZIKV biology; nevertheless, specific efforts are necessary for the development and improvement of the screening methods as to obtain a diagnostic procedure with easy access, performance and at the same time of a low cost. This proposal has the objective to develop and validate a multiplex molecular platform for the confirmatory and discriminatory diagnosis of ZIKV and Dengue virus (DENV) using real-time PCR method. The study predicts also the production and characterization of reagents like endogenous control (avian metapneumovirus) and quantified ZIKV positive control (copies/mL). This study involves the participation of researchers from different institutions: the Blood Center of Ribeirão Preto, Emergency Pediatric Unit at the Faculty of Medicine of Ribeirão Preto, University of São Paulo and Faculty of Zootechnics and Food Engineering, USP (research institution). We believe that the multicenter and multidisciplinary approach will be an efficient strategy for the development and validation of a robust molecular platform for the discriminatory diagnosis of ZIKV and DENV. Additionally, we believe that the establishment of a diagnostic definition of ZIKV infection will permit to study in details the biology of ZIKV, responsible for the Brazilian outbreak and contribute for the better understanding of the pathogenesis of the infection and development of vaccines of immunobiologics.
