Researchers Develop New Rabbit Model for Epstein-Barr Virus
A new laboratory model allows scientists to study Epstein-Barr virus infections in immunosuppressed rabbits.
Updated on Oct. 27, 2026 in Life Sciences
Researchers have successfully established a rabbit model to study Epstein-Barr virus infection. The study provides a new tool for investigating how the virus impacts the spleen and interacts with the host immune system.
Why it matters
This model offers a critical pathway to study the Epstein-Barr virus lifecycle in both B cells and epithelial cells. By simulating human-like infections, researchers aim to better understand the mechanisms behind this virus, which affects the vast majority of the global population.
Epstein-Barr virus infects more than 90% of people worldwide, necessitating better models for study. The research observed that immunosuppressed rabbits infected with either B95-8 or Akata strains showed similar infection magnitudes.
The players
Journal of Virology
This is a peer-reviewed scientific journal published by the American Society for Microbiology that focuses on all aspects of virology.
The details
Immunosuppressed rabbits infected with the virus developed splenomegaly and experienced altered follicle formation within the spleen. While Akata infections yielded more consistent results than B95-8, both strains triggered measurable antibody responses to the EBNA protein family.

The Big Picture
This study is a significant addition to the Epstein-Barr virus lifecycle research program. It provides a new experimental platform that helps bridge existing gaps in understanding how the virus persists and matures within a host.
This breakthrough provides a more reliable method for scientists to test potential therapeutics and vaccines against Epstein-Barr virus. While not an immediate treatment, the model is a necessary step toward eventually developing interventions for the millions of people who carry the virus.
The takeaway
The development of an animal model for Epstein-Barr virus is a critical advancement for understanding a pathogen that affects over 90% of the world. Further research is still required to confirm if these models can fully replicate the viral lifecycle observed in human hosts.
