Reemergence of Lymphocytic Choriomeningitis Mammarenavirus, Germany

Insights

Lymphocytic choriomeningitis mammarenavirus (LCMV) has reemerged in Germany. This zoonotic virus was detected in wild house mice and a golden lion tamarin, highlighting potential risks in both wild and captive environments.

Area of Science:

  • Veterinary Medicine
  • Infectious Diseases
  • Zoonotic Pathogens

Background:

  • Lymphocytic choriomeningitis mammarenavirus (LCMV) is a significant zoonotic pathogen with global distribution.
  • House mice (Mus musculus) are the primary reservoir and transmission vector for LCMV.
  • LCMV poses risks to both animal and human health.

Purpose of the Study:

  • To report the reemergence of LCMV in Germany.
  • To identify LCMV lineages circulating in wild house mouse populations.
  • To investigate LCMV infection in a diseased golden lion tamarin.

Main Methods:

  • Surveillance of wild house mice (Mus musculus domesticus) for LCMV.
  • Molecular detection and lineage determination of LCMV.
  • Diagnostic investigation of a diseased golden lion tamarin (Leontopithecus rosalia).

Main Results:

  • LCMV lineages I and II were detected in wild house mice.
  • LCMV lineage I was identified in a diseased golden lion tamarin from a German zoo.
  • This indicates a reemergence and spread of LCMV in Germany.

Conclusions:

  • The findings confirm the reemergence of LCMV in Germany.
  • LCMV poses a continued threat in both wild rodent populations and zoological collections.
  • Ongoing monitoring is crucial for managing LCMV transmission risks.
