Table 4. Detection of MNV in the intestines of mice that drank WAHS1) at 5 weeks post MNV infection.
| Drinking water | Intestine |
||||
|---|---|---|---|---|---|
| Duodenum | Jejunum | Cecum | Rectum | ||
| WAHS (n=3) | RT-nested PCR | 0/34) | 1/3 | 3/3 | 0/3 |
| MNV titer3) (log10 PFU/g) | <2.3 | <2.3 | 2.92 ± 0.56 | ND5) | |
| Control (n=3)2) | RT-nested PCR | 2/3 | 3/3 | 3/3 | 0/3 |
| MNV titer (log10 PFU/g) | <2.3 | <2.3 | 2.59 ± 0.76 | ND | |
1)Drinking water was changed from 1 week post infection. 2)The drinking water of control mice was not changed to disinfectant. 3)MNV titer was determined by plaque assay. Each value represents the mean ± SD of 3 samples. 4)Each value represents number of positive samples / number of samples examined. 5)ND, not determined.
