The pathogenicity of Getah virus for swine was examined. All 8 pigs (4 adults and 4 piglets) inoculated with Strains MIP-99 and MI-110 developed pyrexia ranging from 39.4 to 40.7 degrees C and anorexia. Mild depression and diarrhea were observed in 2 of the 4 piglets. These clinical signs were transient. Viremia occurred 1-2 days post-inoculation (p.i.) and the maximum titer was 10(3.0) TCID50 0.1 ml-1. The virus was recovered from a piglet autopsied on Day 3 p.i. from spleen and various lymph nodes. The maximum titer of virus (10(3.75) TCID50 0.1 g-1) was detected in the inguinal lymph node. Seroconversion was demonstrated in all the pigs on Day 6 p.i. These results suggest that Getah virus is mildly pathogenic for swine, which may play a role as an amplifying host in nature.
