Replication and compartmentalization of Dobrava-Belgrade virus in the central nervous system

Puntos clave

This research aims to investigate the presence and replication of Dobrava-Belgrade virus in the central nervous system of a heart-transplant recipient.
High-throughput sequencing (HTS) was used to identify viral presence in central nervous system and peripheral specimens.
Genomic analyses were conducted to assess viral populations across different compartments.
Distinct viral populations were observed in the central nervous system compared to peripheral specimens, indicating CNS tropism.
The findings highlight atypical infection presentations related to Dobrava-Belgrade virus in immunosuppressed individuals.

Resumen

A heart-transplant recipient developed fatal neurologic disease. High-throughput sequencing (HTS) identified Dobrava - Belgrade virus in central nervous system (CNS) and peripheral specimens. Genomic analyzes showed distinct viral populations across compartments, suggesting CNS tropism. This case highlights atypical infection presentations in immunosuppressed patients and underscores the diagnostic value of HTS.
