Citation | Journal: Cell / Year: 2024Title: Cryo-EM-based discovery of a pathogenic parvovirus causing epidemic mortality by black wasting disease in farmed beetles. Authors: Judit J Penzes / Martin Holm / Samantha A Yost / Jason T Kaelber / ![]() Abstract: We use cryoelectron microscopy (cryo-EM) as a sequence- and culture-independent diagnostic tool to identify the etiological agent of an agricultural pandemic. For the past 4 years, American insect- ...We use cryoelectron microscopy (cryo-EM) as a sequence- and culture-independent diagnostic tool to identify the etiological agent of an agricultural pandemic. For the past 4 years, American insect-rearing facilities have experienced a distinctive larval pathology and colony collapse of farmed Zophobas morio (superworm). By means of cryo-EM, we discovered the causative agent: a densovirus that we named Zophobas morio black wasting virus (ZmBWV). We confirmed the etiology of disease by fulfilling Koch's postulates and characterizing strains from across the United States. ZmBWV is a member of the family Parvoviridae with a 5,542 nt genome, and we describe intersubunit interactions explaining its expanded internal volume relative to human parvoviruses. Cryo-EM structures at resolutions up to 2.1 Å revealed single-strand DNA (ssDNA) ordering at the capsid inner surface pinned by base-binding pockets in the capsid inner surface. Also, we demonstrated the prophylactic potential of non-pathogenic strains to provide cross-protection in vivo. | |||||||||||||||||||||
