[Phylogenetic analysis of hepatitis E virus strains isolated from both human and swine in Anqing City].

Objective: To determine the genotype and phylogenetic characteristics of hepatitis E virus (HEV) strains isolated from the human and swine in Anqing City.

Methods: Twenty seven sera from sporadic hepatitis E patients and 400 commercial swine bile samples were collected in Anqing City. According to the collection time, the bile samples were equally divided into 4 groups which were named group A, B, C and D respectively.

[Study on the prevalence and genotype of hepatitis E virus among commercial swine population in Eastern and Southern China].

Objective: To determine the prevalence and genotype of hepatitis E virus (HEV) among commercial swine population in Eastern and Southern China.

Methods: Six hundred specimens of swine bile collected from 5 slaughterhouses in Eastern and Southern China from 2007 to 2009 were tested for HEV RNA using nested RT-PCR. PCR products were sequenced for phylogenetic analysis.

[Phylogenetic analysis of sporadic hepatitis E virus in Eastern China].

Objective: To understand phylogenetic characteristics of sporadic hepatitis E virus (HEV) in eastern China.

Methods: Four hundred and thirteen sera were collected from sporadic hepatitis E cases in 14 second- or first-class hospitals in Eastern China from 2005 to 2008 and detected with a nested RT-PCR assay. Partial nucleotide sequences of the HEV isolates were determined for phylogenetic analysis with prototype sequences in the GenBank.
