Serological evidence of Bovine herpesvirus-1, Bovine Viral Diarrhea virus and Schmallenberg virus infections in relation to reproductive disorders in dairy cattle in Ethiopia.

Acta Tropica 2018 Februrary
Reproductive disorders in dairy cattle have been noted to be common in urban and peri-urban dairy production system in Ethiopia. The available reports on the causes of these disorders, however, are not conclusive. A case-control study was designed to investigate the possible association of major reproductive disorders in dairy cattle with exposure status to bovine herpesvirus-1 (BHV-1), bovine viral diarrhea virus (BVDV) and Schmallenberg virus (SBV). Cows with history of abortion/stillbirth were considered as cases (n=204) while, those cows with no such history were taken as control (n=359). The serological screening tests used for all the three viruses were blocking enzyme linked immunosorbent assays (B-ELISAs). Of the total 563 samples tested 58.4%, 43.8% and 32.9% were positive for SBV, BHV-1 and BVDV, respectively. Significant difference between cases and controls were noted for SBV (p=0.026) and BHV-1 exposures (p<0.001). The difference noted for BVDV serostatus was not significant (p>0.05). The highest proportion (28.9%) of concurrent exposures was noted for BHV-1 and SBV, followed by SBV and BVDV (21.5%) and BHV-1 and BVDV (20.2%). Evidence of exposures to all the three viruses were detected in 14.4% of the animals. However, significant difference between cases (39.7%) and controls (22.9%) among cattle with multiple sero-positivity was noted only for BHV-1 and SBV (p<0.001). Proportion of uterine infection (p=0.002) and fetal membrane retention (p=0.005) increased in BHV-1 seropositive animals, while repeat breeding was common (p=0.034) among BVDV exposed ones. Seropositive animals to any of the three viruses were detected in all sampled areas and the proportion of cattle with BHV-1 and SBV exposure history had a higher risk to at least one type of the reproductive disorders mentioned compared to the corresponding sero-negative groups.
