Development of Enhanced Primer Sets for Detection of Norovirus

Table 6

Sensitivity of NV GI using each primer set.

Positive specimens	NKI F/R/F2	GI F1/R1/F2	SRI 1/2/3
GI.3	3	3	—
GI.4	6	2	4
GI.6	5	4	1
GI.8	1	—	1
GI.15	1	—	—
GI	1	1	—
Clinical samples; ( = 18)	17 (94.4%)^*	10 (58.8%)	6 (33.3%)
GI.3	4	3	—
GI.6	1	—	—
Environmental samples ( = 6)	5 (83.3%)	3 (50.0%)	0 (0%)
Total ( = 24)	22 (91.7%)	13 (54.2%)	6 (25.0%)

All values < 0.05 are by -test except for environmental samples (GI F1/R1/F2 and NKI F/R/F2).
Environmental samples were not detected by SRI 1/2/3 primer.
^*Percentage is NV detection/NV positive ratio.
