Xin W, Guo Z, Wang L, Li Y, Shangguan H, Xue K, Chen H, Yang H, Zhao L, Ge J. Multiple genotypes infection and molecular characterization of Torque teno neovison virus: A novel Anelloviridae of mink in China. Res Vet Sci 2023; 161:145-155. [PMID: 37384973 DOI: 10.1016/j.rvsc.2023.06.021] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2023] [Revised: 06/23/2023] [Accepted: 06/23/2023] [Indexed: 07/01/2023]
Abstract
A novel Torque teno neovison virus (TTVs) was identified in specimens collected from dead mink during an outbreak of the Aleutian mink disease virus. Eighteen complete genomic sequences were obtained, ranging from 2109 to 2158 nucleotides in length and consisting of an untranslated region and three open reading frames. The genomic organization of mink TTVs is similar to previously reported anelloviruses. However, the deduced amino acid sequence of its ORF1 protein shows genetic diversity compared to related anelloviruses, suggesting that it represents a putative new species within the Anelloviridae family. This study provides a detailed molecular characterization of the novel mink anelloviruses, including its codon usage pattern, origin, and evolution. Analysis of the viral genomic sequences reveals the existence of multiple genotypes of co-infection. Principal component analysis and phylogenetic trees confirm the coexistence of multiple genotypes. Furthermore, the codon usage analyses indicate that mink TTVs have a genotype-specific codon usage pattern and show a low codon usage bias. Host-specific adaptation analysis suggests that TTVs are less adapted to mink. The possible origin and evolutionary history of mink TTVs were elucidated. Mink TTVs was genetically closely related to giant panda anellovirus, representing a new species. The observed incongruence between the phylogenetic history of TTVs and that of their hosts suggests that the evolution of anellovirus is largely determined by cross-species transmission. The study provides insights into the co-infection and genetic evolution of anellovirus in China.

Abstract
The pangolin is the only scaly mammal in the world and also an important reservoir of pathogenic viruses. Habitat loss and poaching have been shrinking the survival range of pangolins. More information on pangolin virus populations is needed to better understand and assess potential disease risks. In this study, viral metagenomic data were used to reinvestigate the virome in pangolin lung tissue. Complete genome sequences of two novel anelloviruses were acquired and clustered with the referenced feline strains belonging to genus Tettorquevirus and genus Etatorquevirus, respectively. Two genomes belonging to the genus Gemykibivirus, and species Bat-associated cyclovirus 9 were detected, respectively. One genome with a large contig belonging to the genus Senecavirus were also characterized, according to phylogenetic analysis, which can be presumed to be a novel species. In addition, a full genome of endogenous retroviruse (ERV) was assembled from the lungs of pangolin, and this virus may have the possibility of cross-species transmission during the evolution. This virological investigation has increased our understanding of the virome carried by pangolins and provided a reference baseline for possible zoonotic infectious diseases in the future.

Abstract
Background: Viral metagenomics, a high-throughput sequencing combined with virus sequence-independent amplification by random PCR, allows for unbiased detection of virtually any viruses present in samples. Materials & methods: In order to investigate the virome of bronchoalveolar lavage fluid from patients with fever of unknown origin, 58 samples collected from diseased patients were characterized and compared. Results: Some representatives of Anelloviridae were identified, we found the torque teno virus (TTV) accounts for the majority of virus communities and were more prevalent in the specimens of febrile patients. Phylogenetic analysis suggested that these anellovirus isolates were close to the previous TTV available in GenBank®. Conclusion: All these data indicate that the human anellovirus species TTV may associated with fever of unknown origin.

Abstract
BACKGROUND Rodents are widely distributed and are the natural reservoirs of a diverse group of zoonotic viruses. Thus, analyzing the viral diversity harbored by rodents could assist efforts to predict and reduce the risk of future emergence of zoonotic viral diseases. Rodents are commonly used in animal testing, particularly mice and rats. Experimental rats are important animal models, and a history of pathogenic infections in these animals will directly affect the animal trial results. The pathogenicity of Anellovirus (AV) remains poorly understood due to the lack of a suitable model cell line or animal to support the viral cycle. This study aimed to discover possible anelloviruses from the virome in feces of experimental rats by viral metagenomic technique. METHODS Fecal samples were collected from 10 commercial SD rats and pooled into a sample pool and then subjected to libraries construction which was then sequenced on Illumina MiSeq platform. The sequenced reads were analyzed using viral metagenomic analysis pipeline and two novel anelloviruses (AVs) were identified from fecal sample of experimental rats. The prevalence of these two viruses was investigated by conventional PCR. RESULTS The complete genomic sequence of these two AVs were determined and fully characterized, with strain name ratane153-zj1 and ratane153-zj2. The circular genomes of ratane153-zj1 and ratane153-zj2 are 2785 nt and 1930 nt in length, respectively, and both include three ORFs. Ratane153-zj1 closely clustered with members within the genus Wawtorquevirus and formed a separate branch based on the phylogenetic tree constructed over the amino acid sequence of ORF1 of the two AVs identified in this study and other related AVs. While the complete amino acid sequences of ORF1 of ratane153-zj2 (nt 335 to 1390) had the highest sequence identity with an unclassified AV (GenBank No. ATY37438) from Chinchilla lanigera, and they clustered with one AV (GenBank No. QYD02305) belonging to the genus Etatorquevirus from Lynx rufus. Conventional PCR with two sets of specific primers designed based on the two genomes, respectively, showed that they were detectable at a low frequency in cohorts of experimental rats. CONCLUSION Our study expanded the genome diversity of AVs and provided genetic background information of viruses existed in experimental rats.

Abstract
Anelloviruses are small negative-sense single-stranded DNA viruses with genomes ranging in size from 1.6 to 3.9 kb. The family Anelloviridae comprised 14 genera before the present changes. However, in the last five years, a large number of diverse anelloviruses have been identified in various organisms. Here, we undertake a global analysis of mammalian anelloviruses whose full genome sequences have been determined and have an intact open reading frame 1 (ORF1). We established new criteria for the classification of anelloviruses, and, based on our analyses, we establish new genera and species to accommodate the unclassified anelloviruses. We also note that based on the updated species demarcation criteria, some previously assigned species (n = 10) merge with other species. Given the rate at which virus sequence data are accumulating, and with the identification of diverse anelloviruses, we acknowledge that the taxonomy will have to be dynamic and continuously evolve to accommodate new members.

Abstract
Crab-eating (Cerdocyon thous) and Pampas foxes (Lycalopex gymnocercus) are wild canids distributed in South America. Domestic dogs (Canis lupus familiaris) and wild canids may share viral pathogens, including rabies virus (RABV), canine distemper virus (CDV), and canine parvovirus 2 (CPV-2). To characterize the virome of these wild canid species, the present work evaluated the spleen and mesenteric lymph node virome of 17 crab-eating and five Pampas foxes using high-throughput sequencing (HTS). Organ samples were pooled and sequenced using an Illumina MiSeq platform. Additional PCR analyses were performed to identify the frequencies and host origin for each virus detected by HTS. Sequences more closely related to the Paramyxoviridae, Parvoviridae and Anelloviridae families were detected, as well as circular Rep-encoding single-stranded (CRESS) DNA viruses. CDV was found only in crab-eating foxes, whereas CPV-2 was found in both canid species; both viruses were closely related to sequences reported in domestic dogs from southern Brazil. Moreover, the present work reported the detection of canine bocavirus (CBoV) strains that were genetically divergent from CBoV-1 and 2 lineages. Finally, we also characterized CRESS DNA viruses and anelloviruses with marked diversity. The results of this study contribute to the body of knowledge regarding wild canid viruses that can potentially be shared with domestic canids or other species.
