Key result
Pestivirus RNA occurs in ~0.1% of Brazilian bovine serum, driven primarily by HoBi-like strains.
Why the study?
Available molecular data on bovine pestiviruses in Brazil remain geographically fragmented, leaving large areas with limited molecular information.
Cross-Sectional (n=20,267)
Yes
HoBi-like pestivirus is the predominant pestivirus circulating in cattle across distinct regions of Brazil, highlighting the need for updated diagnostic surveillance.

Low pestivirus prevalence in Brazilian cattle sera highlights HoBi-like predominance; hypothesis-generating for targeted surveillance without practice change.
Baumbach et al. (2026) conducted a cross-sectional in Pestivirus infection in cattle (n=20,267). Pestivirus screening was evaluated on Detection of pestivirus RNA. Pestivirus RNA was detected in 0.10% of 20,267 bovine serum samples from Brazil, with HoBi-like pestivirus accounting for 90.5% of all positive detections.
