Abstract
In 2010, a HoBi-like pestivirus was isolated from clinically affected calves in Italy. This European virus reproduced a milder form of disease under experimental conditions and was genetically related to previously reported HoBi-like strains. Isolation of this novel virus from a clinical outbreak may have implications for cattle health and prophylactic programs.
Genus Pestivirus (family Flaviviridae) includes Bovine viral diarrhea virus type 1 (BVDV-1) and Bovine viral diarrhea virus type 2 (BVDV-2), Classical swine fever virus (CSFV), Border disease virus (BDV), and other pestivirus species detected in wild ruminants (1,2). In 2004, an atypical pestivirus was isolated from a contaminated batch of calf serum originating from Brazil. This virus, named D32/00_HoBi, was proposed as prototype of a new pestivirus species, BVDV-3 (3). Although additional HoBi-like strains have been detected in South America (4), currently, there is a unique report of natural infection in cattle caused by a HoBi-like strain, Th/04_KhonKaen, which was isolated from a bovine serum sample collected during an epidemiologic survey for BVDV in Thailand (5). However, the virus was not associated with any evident clinical signs. Here we report the biologic and genetic characterization of a HoBi-like strain from Europe that was isolated from cattle during an outbreak of respiratory disease in Italy.
