Signs of central nervous system (CNS) dysfunction such as convulsions and opisthotonus.
One placebo-treated piglet showed central nervous system dysfunction and reached a score of 25 on the last day of the experiment.
Three additional piglets became recumbent.
Two piglets died a few hours after experimental infection prior to the first feeding and measurement of body temperature.
For the detailed clinical scoring system see Table S1.
