Paper Review: Discovery of a novel double-stranded DNA virus associated with ant labial gland disease reveals its long-term interaction with ants…. José Roberto Vargas Villanueva………. This article reports the identification of a novel double-stranded DNA (dsDNA) virus discovered in the labial gland cells of Camponotus japonicus ants, establishing a clear association between this pathogen and labial gland disease, a pathology characterized by the inflammation of the labial gland. Through genomic DNA extraction and analysis, the researchers successfully characterized the viral genome architecture, designating this newly identified sequence as Camponotus japonicus labial gland disease virus (CjLGDV).

Comparative analysis of CjLGDV genome against primary databases revealed the presence of a related viral sequence, which the authors have provisionally named as Anoplolepis gracilipes labial gland disease virus (AgLGDV). This second virus appears to share significant genomic features with CjLGDV, suggesting a common evolutionary origin. Subsequent phylogenetic analysis of both viral genomes demonstrated conserved genomic regions that strongly support the establishment of a novel viral family within the order Lefavirales, class Naldaviricetes.

These findings contribute significantly to our understanding of insect virology, particularly regarding viruses affecting social hymenopterans. The discovery expands the known diversity of dsDNA viruses host range and provides a foundation for future research………https://journals.asm.org/doi/10.1128/jvi.01178-25 ………. https://cicese.zoom.us/j/87006389972?pwd=9sWluAL27rbgpZEqYcJFkuYZgo8Qcr.1
