AbstractA hybrid sequencing approach, using short and long reads sequencing, was employed for characterizing the genomes of the free-living amoeba host Vermamoeba vermiformis, along with its Dependentiae endosymbiont Vermiphilus pyriformis. The amoeba host reconstructed nuclear genome is 39.5 Mb, and its full mitochondrial genome is 61.7 kb. The closed, circular genome of the Dependentiae endosymbiont Vermiphilus pyriformis, naturally infecting V. vermiformis is 1.1 Mb.

Many case reports emphasize the fact that Free-Living Amoebae (FLA) can relatively easily get in contact with humans or animals. The presence of several facultative parasitic FLA in habitats related to human activities supports their public health relevance. While some strains of Acanthamoeba,Naegleria fowleri,Balamuthia mandrillarisand several other FLA have been described as facultative human pathogens, it remains controversial whetherVermamoeba vermiformisstrains may have a pathogenic potential, or whether this FLA is just an incidental contaminant in a range of human cases. However, several cases support its role as a human parasite, either as the only etiological agent, or in combination with other pathogens. Additionally, a wide range of FLA is known as vectors of microorganisms (endocytobionts), hereby emphasizing their environmental significance. Among those FLA serving as hosts for and vectors of (pathogenic) endocytobionts, there are also descriptions ofV. vermiformisas a vehicle and a reservoir of those endocytobionts. The involvement in animal and human health, the role as vector of pathogenic microorganisms and the pathogenicity in cell cultures, led to the assumption thatV. vermiformisshould be considered relevant in terms of public health and environmental health.

ABSTRACT The family of giant viruses is still expanding, and evidence of a translational machinery is emerging in the virosphere. The Klosneuvirinae group of giant viruses was first reconstructed from in silico studies, and then a unique member was isolated, Bodo saltans virus. Here we describe the isolation of a new member in this group using coculture with the free-living amoeba Vermamoeba vermiformis. This giant virus, called Yasminevirus, has a 2.1-Mb linear double-stranded DNA genome encoding 1,541 candidate proteins, with a GC content estimated at 40.2%. Yasminevirus possesses a nearly complete translational machinery, with a set of 70 tRNAs associated with 45 codons and recognizing 20 amino acids (aa), 20 aminoacyl-tRNA synthetases (aaRSs) recognizing 20 aa, as well as several translation factors and elongation factors. At the genome scale, evolutionary analyses placed this virus in the Klosneuvirinae group of giant viruses. Rhizome analysis demonstrated that the genome of Yasminevirus is mosaic, with ∼34% of genes having their closest homologues in other viruses, followed by ∼13.2% in Eukaryota, ∼7.2% in Bacteria, and less than 1% in Archaea. Among giant virus sequences, Yasminevirus shared 87% of viral hits with Klosneuvirinae. This description of Yasminevirus sheds light on the Klosneuvirinae group in a captivating quest to understand the evolution and diversity of giant viruses. IMPORTANCE Yasminevirus is an icosahedral double-stranded DNA virus isolated from sewage water by amoeba coculture. Here its structure and replicative cycle in the amoeba Vermamoeba vermiformis are described and genomic and evolutionary studies are reported. This virus belongs to the Klosneuvirinae group of giant viruses, representing the second isolated and cultivated giant virus in this group, and is the first isolated using a coculture procedure. Extended translational machinery pointed to Yasminevirus among the quasiautonomous giant viruses with the most complete translational apparatus of the known virosphere.
