Abstract:
Zika (ZIKV), Dengue (DENV) and Chikungunya viruses (CHIKV) co-circulate in the same geographical areas during the same seasonal period through the same biting arthropods. Therefore a rapid sensitive and specific molecular assay for these viruses would be a considerable help in the disease management and the epidemiological survey. We developed a one-step multiplex real-time PCR for the simultaneous detection of these viruses. Intra and inter-reproducibilities varied from 0.41% to 3.29% and from 1.13% to 4.93% for each virus respectively. The specificity was 100%. Whole blood, plasma and urines were used for comparison with commercially available monoplex assays (RealStar® kits, Altona Diagnostics GmbH, Hamburg, Germany). The concordance was 96%, 92.9% and 95.7% for ZIKV, DENV and CHIKV respectively. No cross reaction and no PCR inhibition were observed for any of the clinical samples. This test can thus be used as a rapid molecular assay for ZIKV, DENV1-4 and CHIKV infections.

Homogeneous Equilibria for Gaseous Reactions
For gas-phase reactions, the equilibrium constant may be expressed in terms of either the molar concentrations (Kc) or partial pressures (Kp) of the reactants and products. A relation between these two K values may be simply derived from the ideal gas equation and the definition of molarity. According to the ideal gas equation:
Reaction Mechanisms
For instance, the decomposition of ozone appears to follow a mechanism with two steps:
