Figure 1

Colorimetric test using all primer sets on positive controls (PC) and non-template controls (NTC). A visible color change from red to yellow develops in PC tubes in the colorimetric identification, and negatives remain red. The color development was observed before (0 min) and after the reaction (between 30 and 60 min). The green circle denotes the earliest color development in the PC reaction tubes. The red circles represent the NTC reactions that led to the earliest misamplification.
