Abstract

Porcine torovirus (PToV) was detected from intestinal samples of piglets with diarrhea from 20 farms in southwest China. The total prevalence of PToV was 45% (9 out of 20 farms); it was the first detection of PToV in China, and also the study analyzed the phylogenetic relationships between the Chinese PToV and PToV reference strains as well as other representative toroviruses. Genetic and phylogenetic analysis showed the existence of genetic diversity among geographically separated PToV. Statistical analysis of the PToV positive rate as well as a survey for other enteric pathogens in diarrheic pigs suggests that PToV may play a role as a causative agent of severe diarrhea in piglets.

Phylogenetic analysis of partial PToV-S gene sequences obtained from Chinese farms and torovirus sequences available in GenBank. Gene sequences were aligned using the ClustalW method and the phylogenetic tree was performed by the neighbour joining method using 1000 bootstrap. Sequences from this study were marked red.
