Аннотация
Hepatitis E virus (HEV) typically causes self-limiting acute viral hepatitis, however chronic infection and extrahepatic manifestations have increasingly become a significant health problem. Domestic pigs and wild boars are the main reservoirs of HEV genotype 3 and genotype 4 for human infections in industrialized countries, although molecular and serological evidence suggest that several additional animal species may act as HEV hosts. In this study, by assessing serologically and molecularly the sera of 324 household cats from Apulia region (Italy), HEV antibodies were detected with an overall prevalence of 3.1%. Viral RNA was not detected in the sera of the animals using both HEV-specific assays and a pan-hepevirus broadly reactive set of primers for Hepeviridae. These findings document a low seroprevalence to HEV in cats in the investigated geographical setting. The exact nature of the HEV-like strains circulating in feline population remains to be established.
