Positive samples for N. mikurensis in the qPCR assay were further validated with a nested PCR assay (Figure 1). The nPCR included primers targeting the 16S rRNA gene of N. mikurensis, to amplify a 1259-bp-long amplicon (Table 1). The 25 μL reactions of the first round of amplification consisted of 12.5 μL Supreme NZYTech Taq 2× Green Master Mix (NZYTech), 0.5 μL of each of the primers Neo_16S_95_F/Neo_16S_1393_R (10 μM, Table 1), and 9 μL RNAse free water.
