The Mininucleoviridae are crustacean-infecting viruses thought to drive mortality across aquatic biomes. Three have been characterised from Carcinus maenas, Panulirus argus, and Dikerogammarus haemobaphes. We screened 202 SRA datasets (NCBI) for novel mininucleoviruses from 44 amphipod species. Three metatranscriptome datasets from Gammarus lacustris contained sequences with similarity to Dikerogammarus haemobaphes mininucleovirus. Assembly resulted in 19 transcripts, 16 were putatively polycistronic. The putative Gammarus lacustris mininucleovirus shares 46 homologues with other mininucleoviruses (similarity range: 24.07 - 78.2 %). The transcripts from this putative virus highlight its likely association with the Mininucleoviridae.

The Nudiviridae are a family of large double-stranded DNA viruses that infects the cells of the gut in invertebrates, including insects and crustaceans. The phylogenetic range of the family has recently been enhanced via the description of viruses infecting penaeid shrimp, crangonid shrimp, homarid lobsters and portunid crabs. Here we extend this by presenting the genome of another nudivirus infecting the amphipod Dikerogammarus haemobaphes.

The amphipod is a high-risk carrier of parasites that impact wildlife in its non-native range. Studies using the mitochondrial genes, Cytochrome Oxidase Sub-Unit 1 (cox1) and small-subunit ribosomal RNA gene (16S), provide some nucleotide detail for understanding the evolution and phylogeography of this species. Despite this, the origins of the invasion remain unknown, as do the origins of its parasites.

Panulirus argus virus 1 (PaV1) is the only known virus infecting the Caribbean spiny lobster () from the Caribbean Sea. Recently, related viruses, Dikerogammarus haemobaphes virus 1 (DhV1) and Carcinus maenas virus 1 (CmV1), have been detected in the demon shrimp () and the European shore crab (), respectively, from sites in the United Kingdom. The virion morphology of these crustacean viruses is similar to that of iridoviruses.
