Abstract

Aim. Experimental reproduction of HEV-infection in mini-pigs and comparative analysis of virological and immunological characteristics of experimental infection. Materials and methods. Wiesenauer minipigs (2 females and 4 males, age 50 - 60 days, weight 5-10 kg) were infected by HEV genotype 3 strain isolated from swine feces in Belgorod region in 2013. The virus was administered as a 10% clarified feces extract (800 pi). Blood (weekly) and feces (daily) were sampled from the animals for 49 days. Anti-HEV IgG were determined in sera samples using DS- ElA-ANTI-HEV-G (Diagnostic Systems) system, HEV RNA in samples of feces extracts and blood sera - RT-PCR. Results. Wiesenauer minipigs were sensitive to HEV genotype 3 infection, infection developed in all the animals after administration of the virus, that was accompanied by the presence of HEV RNA in feces for 2 weeks and seroconversion by anti-HEV. Comparative analysis of virological characteristics of experimental H EV-infection in mini- and standard pigs has shown, that the duration of the infection in mini-pigs is shorter, and seroconversion by anti-HEV occurs earlier. Conclusion. Sensitivity to HEV genotype 3 and lower weight make mini-pigs a comfortable alternative to standard swine and primates for modelling HEV infection in vivo.
