“…Similarly, the MPAV2 was found to have 49.79%–67.08% ORF1 nucleotide sequence identity with the feline anelloviruses. Of these, the closest evolutionary relatives of MPAV2 were Torque teno felis viruses (CCB29_anello1, MT537978 and CCB31_anello1, MT537979), which were detected in the blood sample of caracals in South Africa 21 …”

Based on this criterion, we hypothesize that MPAV1 and MPAV2 are new species in their respective genera.…”

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 Batassociated 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.

“…With the development of HTS protocols to explore the diversity of existing viruses, previous works have identified new anelloviruses species in wildlife - bats, rodents 38 , seals 29 , wild felids 30 , canids 31 and non-human primates 9,10,25,27,32,33 . In this work, we sequenced and characterized two novel Anelloviridae species genomes in NP, increasing the host range for this family.…”

“…TTVs 27,30 , no clear evolutionary model has been proposed to assess TTV diversity. Although this study focused on NP TTVs, we argue that the within-species diversity followed by codivergence model might explain the drivers of diversification for the whole Anelloviridae We thank to all the workers of the Centro de Primatologia de Brasília, Universidade de Brasília (Distrito Federal, Brazil) for assistance with sample collection and to the fantastic LDDV members, in special to Déa Mota, for the wonderful team work.…”

“…While the diversity and host span of Anelloviridae is constantly being updated 9,10,25,[27][28][29][30][31][32][33] , little is known about the factors driving their diversification dynamics. Specifically, whether the generation of novel viral species is driven by zoonotic spillovers to new host species or co-divergence with long-term host lineages has not been formally assessed.…”

The development of high throughput sequencing (HTS) technologies and metagenomics protocols deeply impacted the discovery of viral diversity. Moreover, the comprehension of evolution and immunology of the Neotropical primates (NP) and their susceptibility to infectious diseases are central for the characterization of the scope of etiological agents that may impact global health, due to their evolutionary proximity to Old World primates, including humans. In the present work, novel anelloviruses were detected and characterized through HTS protocols in the NP Callithrix penicillata, the common black-tufted marmoset. De novo assembly of generated sequences was carried out and a total of 15 contigs were identified with complete Anelloviridae ORF1 gene, two of them including a flanking GC-rich region, confirming the presence of two whole novel genomes of ~3kb. The identified viruses were monophyletic within the Epsilontorquevirus genus, a lineage harboring previously reported anelloviruses infecting hosts from the Cebidae family. The genetic divergence found in the new viruses characterized two novel species, named Epsilontorquevirus callithrichensis I and II. The phylogenetic pattern inferred for the Epsilontorquevirus genus was consistent with the topology of their host species tree, echoing a virus-host diversification model observed in other viral groups. This study expands the host span of Anelloviridae and provides insights into their diversification dynamics, highlighting the importance of sampling animal viral genomes to obtain a clearer depiction of their long-term evolutionary processes.
