Complete genome of hepatitis E virus from laboratory ferrets

Area of Science:

• Virology
• Genomics
• Zoonotic Diseases

Background:

• Hepatitis E virus (HEV) is a significant human pathogen.
• Laboratory ferrets are increasingly used in research settings.
• Understanding HEV in animal reservoirs is crucial for public health.

Purpose of the Study:

• To identify and characterize the complete genome of HEV in laboratory ferrets.
• To assess the genetic diversity and origin of ferret-associated HEV.
• To determine the prevalence of HEV contamination in laboratory ferrets.

Main Methods:

• Whole-genome sequencing of HEV from infected ferrets.
• Phylogenetic analysis to compare HEV sequences.
• Nucleotide (nt) sequence identity analysis.

Main Results:

• The complete HEV genome was successfully sequenced from laboratory ferrets.
• Ferret HEV isolates showed low nucleotide sequence identity (82.4%-82.5%) to European strains.
• This genetic divergence indicates significant diversity within the ferret HEV population.

Conclusions:

• Laboratory ferrets can harbor genetically diverse HEV strains.
• The identified ferret HEV may represent a distinct lineage.
• Further research is needed to understand HEV transmission dynamics in ferrets and potential zoonotic implications.
