Traces of history conserved over 600 years in the geographic distribution of genetic variants of an RNA virus: Bovine viral diarrhea virus in Switzerland

Abstract: The first records of smallpox and rabies date back thousands of years and foot-and-mouth disease in cattle was described in the 16th century. These diseases stood out by their distinct signs, dramatic way of transmission from rabid dogs to humans, and sudden appearance in cattle herds. By contrast, infectious diseases that show variable signs and affect few individuals were identified only much later. Bovine viral diarrhea (BVD), endemic in cattle worldwide, was first described in 1946, together with the epony… Show more

“…Differentiation of approximately half of the seropositive samples indicated that the majority of wild ruminant sera contained antibody to BDV rather than BVDV (147). This might be corroborated by the observations that using RT-PCR, only one single serum from a chamois contained viral RNA that could be typed as BVDV-1 h (146), the most prominent genotype found in cattle in Switzerland (34). These data indicate that wild ruminants in Switzerland do not represent a pestivirus reservoir but are rather an incidentally spill-over host and, therefore, do not pose a risk to BVD eradication in cattle.…”

“…Ruminant pestiviruses have probably circulated for hundreds of years in their hosts (34,35) causing large economic losses (36)(37)(38)(39). To reduce this financial burden, several countries, or regions introduced control programmes to reduce or even eradicate BVDV from the cattle population (40)(41)(42)(43)(44)(45)(46)(47)(48)(49)(50).…”

“…In all BVDV seropositive animals, the highest antibody titers were measured against BVDV1h, which was the most frequent subgroup in Switzerland prior to eradication. 36 This observation argues for a bovine source of transmission. Interestingly, 1 sheep on farm 2 was BDV seropositive.…”

“…Phylogenetic analysis indicates that BVDV has been circulating in cattle populations for hundreds of years 10,11 . Recent advances in diagnostic methods, sequencing, and phylogenetic analyses have identified 21 Pestivirus A subtypes (BVDV1a‐u) and 4 Pestivirus B subtypes (BVDV2a‐2d) 12 .…”
