Since the inclusion of sapovirus in routine testing, pathologists have noted that a majority of pigs, with and without diarrhea, tested positive for this agent. However, they also observed that younger pigs appeared to have a heavier load of virus in their intestines and it was observed that pigs with enteric lesions of villus atrophy that were PCR positive for rotaviruses were also frequently positive for sapovirus.
Noting coinfection trends, the researchers share:
- The presence of sapovirus is significantly correlated with the presence of rotaviruses A, B and C.
- The analysis showed an association between sapovirus and beta-hemolytic Escherichia coli.
