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.

D008297 Male Males
D003967 Diarrhea An increased liquidity or decreased consistency of FECES, such as running stool.

Diarrhea is not hyperdefecation or increased fecal weight. Diarrheas
D005260 Female Females
D005334 Fever An abnormal elevation of body temperature, usually as a result of a pathologic process. Pyrexia,Fevers,Pyrexias
D000524 Alphavirus A genus of TOGAVIRIDAE, also known as Group A arboviruses. They are serologically related to each other and are transmitted by mosquitoes. The type species is the SINDBIS VIRUS.
