Molecular and serological surveillance of Hepatitis E virus in wild and domestic carnivores in Brandenburg, Germany.

Abstract

Hepatitis E virus (HEV) is a zoonotic virus which circulates in pigs and wild boars as main reservoir species. To reveal the infection rate in carnivores, we have carried out a monitoring study of raccoons, raccoon dogs, dogs and cats sampled in Brandenburg, Germany. In summary, 53.8% (43 of 80) of the raccoons, 34.3% (25 of 73) of the raccoon dogs, 56.6% (47 of 83) of dogs and 32.3% (21 of 65) of cats were tested positive for HEV-specific antibodies. No viral RNA could be detected. This first description of anti-HEV antibodies in raccoons and raccoon dogs worldwide and in dogs and cats in Germany highlights the natural host range expansion of HEV.
