Table 1. Virus isolation from the stool specimens from healthy children.
| Isolatesa | Stool specimens (N = 330) | ||
|---|---|---|---|
| Virus | Types of infected cell lines | Number of CPE-positive samples (n)b | Isolation rate (%) |
| PVs | RD and L20B | 4 | 1.2 |
| NPEVs | RD | 14 | 4.2 |
| NPEVs | HEp-2c | 26 | 7.9 |
| NPEVs | RD and HEp-2c | 19 | 5.8 |
| Total NPEVs | 59 | 17.9 | |
| Total EVs | 63 | 19.1 | |
a PVs, polioviruses; NPEVs, Non-polio enteroviruses; EVs, enteroviruses
b CPE, cytopathic effects; Given the fact that 19 specimens produced isolates on both cell lines, a total of 78 NPEV isolates were obtained.
