Role of wildlife and domestic pigs as reservoirs for hepatitis E virus (HEV): study of the infection in suids and cervids and of the susceptibility of pigs to HEV originating from wild boa
better mimics the natural route of infection than the intravenous model and shows a limited spread of the virus in the organism, a low viremia and low levels of the virus in the organs. These points should ...

Distinction between persistent and transient infection in a bovine viral diarrhoea (BVD) control programme: appropriate interpretation of real-time RT-PCR and antigen-ELISA test results.
40 days later from 74 PCR positive animals to detect persistent viremia: 17 (23%) of these were still PCR positive and considered to be PI and the 57 that no longer tested positive were assumed to be ...

Experimental co-infections of calves with bluetongue virus serotypes 1 and 8.
Coinfection Viremia Abstract: The contemporary circulation of multiple bluetongue virus (BTV) serotypes or strains within the same territory can imply the co-infection of the ruminant and/or the vector ...
