Key result
Bovine viral diarrhea virus RNA was detected in 47.74% of serum samples from cattle with reproductive disorders, with all positive samples identified as subgenotype BVDV-1a.
Why the study?
Bovine viral diarrhea virus causes significant economic losses, but the genetic diversity of circulating strains in cattle from backyard farms in Tepalcingo, Morelos, Mexico, required evaluation.
Population
111 serum samples from cattle with reproductive disorders in backyard farms in Tepalcingo, Morelos, Mexico
Design
Molecular epidemiological investigation

BVDV-1a is highly prevalent in backyard cattle farms with reproductive disorders in Tepalcingo, Mexico, highlighting the need for targeted biosafety and control measures.
Basurto-Alcántara et al. (2022) conducted a cross-sectional in Bovine viral diarrhea virus (BVDV) infection (n=111). Bovine viral diarrhea virus (BVDV) infection was evaluated on Detection of viral RNA. Bovine viral diarrhea virus RNA was detected in 47.74% of serum samples from cattle with reproductive disorders, with all positive samples identified as subgenotype BVDV-1a.
