Experimental infection of cattle, sheep and pigs with 'Hobi'-like pestivirus.

To date, limited information is available on the ability of 'Hobi'-like pestiviruses (putative bovine viral diarrhoea 3) to infect and cause disease in animal species traditionally affected by pestiviruses. In order to obtain new insights into host range and pathogenic potential of this atypical pestivirus, BVDV-seronegative calves (n=5), lambs (n=5) and piglets (n=5) were experimentally infected with the European 'Hobi'-like strain Italy-1/10-1, whereas two animals per species served as uninfected controls. Appearance of clinical signs, leukopenia, viremia, viral shedding and seroconversion were monitored for 28 days post-infection.

Cidofovir does not prevent caprine herpesvirus type-1 neural latency in goats.

Background: Cidofovir (CDV) is an acyclic nucleoside phosphonate that exhibits a potent antiviral activity against several DNA viruses. In previous studies, CDV has been shown to significantly reduce the clinical severity and the viral shedding in primary caprine herpesvirus type-1 (CpHV-1) infection in goats. CpHV-1 is an alpha-herpesvirus showing many biological similarities with human herpesvirus type-2 (HHV-2); therefore, studies conducted on the CpHV-1 goat model could provide useful information on the pathogenesis, therapy and prevention of HHV-2 infection in humans.
