Abstract EN
Dengue is one of the major public health concerns in the world.
Since all the four serotypes are actively circulating in Mexico, there is a need to develop an efficient diagnosis system to improve case management of the patients.
There exist few studies evaluating the use of the NS3 protein as a protective antigen against dengue virus (DENV).
In this paper we show the expression of a recombinant NS3 protein from all serotypes of dengue virus (GST-DVNS3-1-4) and report a reliable “in-house detection system” for the diagnosis of dengue infection which was field-tested in a small village (Tezonapa) in the state of Veracruz, Mexico.
The fusion proteins were immunogenic, inducing antibodies to be able to recognize to antigens up to a 1 : 3200 dilution.
The purified proteins were used to develop an in-house detection system (ELISA) and were further tested with a panel of 239 serum samples.
The in-house results were in excellent agreement with the commercial kits with κ=0.934±0.064 (95% CI = 0.808–1.061), and κ=0.872±0.048 (95% CI = 0.779–0.965) for IgM and IgG, respectively.
The agreement between the NS1 antigen detection versus the rNS3 ELISA, κ=0.837±0.066 (95% CI = 0.708–0.966), was very good.
Thus, these results demonstrate that recombinant NS3 proteins have potential in early diagnosis of dengue infections.
