b
<: Virus titers were under the detection limit (0.67 log10TCID50/mL).
c
< 0.67: One CPE-positive well was detected in quadruplicate culture of undiluted samples.
d
< 1.33: Three CPE-positive wells were detected in quadruplicate culture of undiluted samples.
e
< 1.00: Two CPE-positive wells were detected in quadruplicate culture of undiluted samples.
