Natural intrauterine infection with Schmallenberg virus in malformed newborn calves

Emerg Infect Dis. 2014 Aug;20(8):1327-30. doi: 10.3201/eid2008.121890.

Abstract

We surveyed morphologic alterations in calves in Belgium that were naturally infected in utero by Schmallenberg virus (SBV) and born with deformities during January-March 2012. SBV-specific RNA was distributed unevenly in different tissues. Natural intrauterine SBV infection of calves might cause serious damage to the central nervous system and muscles.

Keywords: Schmallenberg virus; bovine; calves; malformations; viral RNA; viruses.
