Comparison of virus replication in 2-week-old ducks between HK483 and MON3. Three days post-inoculation, the brains, tracheas, lungs, kidneys, livers, and colons were collected. Viruses in each of the tissue samples were titrated in 10-day-old embryonated chicken eggs and titers were expressed as EID50/g of tissues. The mean virus titers in each of the tissues and standard deviations are shown. The lower limit of detection was 101.5 EID50/g. Virus titers were statistically analyzed by Student’s paired t-test. Significant differences are indicated by asterisks (** p < 0.001, * p < 0.05).
