Analytical specificity of ZIKV RT-LAMP in mosquito samples. Crude lysates of uninfected A. aegypti were spiked with different arboviruses (DENV 1–4, YFV, CHIKV and ZIKV) circulating in Brazil so the final concentration would be 106 PFU per reaction. Spiked samples were then assayed by ZIKV RT-LAMP. The amplification products were observed by naked eye under natural light (A), under UV irradiation (B) and agarose gel electrophoresis (C). M: molecular weight marker. NTC (non-template control): water.
