Abstract
Haemaphysalis longicornis ticks, commonly found in East Asia, can transmit various pathogenic viruses, including the severe fever with thrombocytopenia syndrome virus (SFTSV) that has caused febrile diseases among humans in Hubei Province. However, understanding of the viromes of H. longicornis was limited, and the prevalence of viruses among H. longicornis ticks in Hubei was not well clarified. This study investigates the viromes of both engorged (fed) and free (unfed) H. longicornis ticks across three mountainous regions in Hubei Province from 2019 to 2020. RNA-sequencing analysis identified viral sequences that were related to 39 reference viruses belonging to unclassified viruses and seven RNA viral families, namely Chuviridae, Nairoviridae, Orthomyxoviridae, Parvoviridae, Phenuiviridae, Rhabdoviridae, and Totiviridae. Viral abundance and diversity in these ticks were analysed, and phylogenetic characteristics of the Henan tick virus (HNTV), Dabieshan tick virus (DBSTV), Okutama tick virus (OKTV), and Jingmen tick virus (JMTV) were elucidated based on their full genomic sequences. Prevalence analysis demonstrated that DBSTV was the most common virus found in individual H. longicornis ticks (12.59%), followed by HNTV (0.35%), whereas JMTV and OKTV were not detected. These results improve our understanding of H. longicornis tick viromes in central China and highlight the role of tick feeding status and geography in shaping the viral community. The findings of new viral strains and their potential impact on public health raise the need to strengthen surveillance efforts for comprehensively assessing their spillover potentials.

Mekata H, Kobayashi I, Okabayashi T. Detection and phylogenetic analysis of Dabieshan tick virus and Okutama tick virus in ticks collected from Cape Toi, Japan. Ticks Tick Borne Dis 2023; 14:102237. [PMID: 37595529 DOI: 10.1016/j.ttbdis.2023.102237] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2023] [Revised: 07/23/2023] [Accepted: 08/01/2023] [Indexed: 08/20/2023]
Abstract
New technologies have led to the discovery of novel tick-borne and tick-associated viruses. Dabieshan tick virus (DaTV) and Okutama tick virus (OkTV), which belong to the family Phenuiviridae, were discovered in ticks in China and Japan, respectively, in the 2010s. Although it is unknown whether these viruses cause disease in animals or humans, all tick-associated viruses have the potential to become etiological agents of infectious diseases through gene reassortment. Therefore, it is important to elucidate the ecology of these viruses, regardless of their pathogenicity. In this study, ticks were collected year-round in Cape Toi, Miyazaki Prefecture, Japan, and an epidemiological survey of tick-associated phenuiviruses was performed. A total of 516 ticks collected from the vegetation by dragging flannel sheets were used for analysis. Pan-phenuivirus reverse transcription PCR was performed on the tick samples, and DaTV and OkTV were detected. We found that 37.0% (85/230) and 23% (16/71) of nymphal and adult Haemaphysalis longicornis were infected with DaTV, respectively, and 10% (6/62) and 13% (1/8) of nymphal and adult Haemaphysalis flava were infected with OkTV, respectively. Phylogenetic analysis indicated that the DaTV identified in this study formed a unique clade that was distinct from the strains identified in China. The survey revealed that DaTV is distributed not only in China, but also in Japan. We believe that this study contributes to our understanding of the prevalence of tick-associated viruses.

Abstract
Ticks are important vector arthropods that transmit various pathogens to humans and other animals. Tick-borne viruses are of particular concern to public health as these are major agents of emerging and re-emerging infectious diseases. The Phenuiviridae family of tick-borne viruses is one of the most diverse groups and includes important human pathogenic viruses such as severe fever with thrombocytopenia syndrome virus. Phenuivirus-like sequences were detected during the surveillance of tick-borne viruses using RNA virome analysis from a pooled sample of Haemaphysalis formosensis ticks collected in Ehime, Japan. RT-PCR amplification and Sanger sequencing revealed the nearly complete viral genome sequence of all three segments. Comparisons of the viral amino acid sequences among phenuiviruses indicated that the detected virus shared 46%-70% sequence identity with known members of the Kaisodi group in the genus Uukuvirus. Furthermore, phylogenetic analysis of the viral proteins showed that the virus formed a cluster with the Kaisodi group viruses, suggesting that this was a novel virus, which was designated "Toyo virus" (TOYOV). Further investigation of TOYOV is needed, and it will contribute to understanding the natural history and the etiological importance of the Kaisodi group viruses.

Abstract
Dabieshan tick virus (DBV) belongs to Phlebovirus and its pathogenicity
to human and animals is unknown. To investigate the presence of Dabieshan tick virus in
Zhoushan, 353 ticks were collected from May 2018 to October 2019. The detection result
showed that the average prevalence rate among these samples was 30.3% (107 positives out
of 353 samples), which means DBVs are widely distributed in tick populations in Zhoushan
of China. In a phylogenetic analysis based on the nucleotide sequences of the L and S
segments of the virus (ZS-DBS-2018 tick virus) in the study, it clustered with Dabieshan
tick virus (KM817666.1, KM817733.1) with a 97.1% and 99.6% nucleotide identity,
respectively. Further studies involving virus isolation are required to characterize
Dabieshan tick virus and to expand the geographical distribution of the sampled ticks.

Abstract
Background Tick-borne phenuivirus (TBPVs) comprise human and animal viruses that can cause a variety of clinical syndromes ranging from self-limiting febrile illness to fatal haemorrhagic fevers. Objective Detect Phlebovirus (Family Phenuiviridae) in ticks collected from domestic animals in Córdoba, Colombia. Methods We collected 2365 ticks from domestic animals in three municipalities of the Department of Cordoba, Colombia in 2016. Ticks were identified and pooled by species for RNA extraction. A nested real-time PCR with specific primers for Phlebovirus and a specific probe for Heartland virus (HRTV) formerly a Phlebovirus, now a Banyangvirus were performed. Also, a conventional nested PCR, with the same specific primers was used to detect other Phleboviruses, with positive reactions indicated by an amplified cDNA fragment of approximately 244 bp determined by gel electrophoresis. These bands were gel-purified and sequenced by the Sanger method. Results Using real-time RT-PCR, no positive results for HRTV were found. However, using conventional nested PCR 2.2% (5/229 pools) yielded a product of 244 bp. One positive sample was detected in a pool of Dermacentor nitens ticks collected from a horse, and the four remaining positive pools were from Rhipicephalus microplus collected from cattle. The five positive nucleotide sequences had identities of 93 to 96% compared to a section of the L-segment of Lihan Tick virus, a Phlebovirus originally detected in R. microplus ticks in China. The strongest identity (96–99%) was with Lihan Tick virus detected in R. microplus ticks from Brazil. Conclusions This is the first report of viral detection in ticks in Colombia. We detected a Colombian strain of Lihan Tick virus. We recommend expanding the sampling area and carrying out more eco-epidemiological studies related to epidemiological surveillance of viruses on ticks in Colombia.

Abstract
Ticks (Ixodida) are hematophagous ectoparasites that harbor and transmit diverse species of viruses, some of which cause serious diseases with worldwide veterinary and human health consequences. Rhipicephalus microplus is an important cattle tick in Colombia, where it causes significant economic losses. Despite the importance of this tick, its viral profile is unknown. RNA sequencing was used in this study as a surveillance method for virus detection in R. microplus. Most of the viral origin contigs were assigned to two putative viruses: one chuvirus (Wuhan tick virus 2) and one phlebovirus-like (Lihan tick virus). In addition, viral contigs corresponding to two jingmenviruses previously reported in R. microplus from China and Brazil were detected, as well as a novel putative tymovirus, named here as Antioquia tymovirus-like 1 (ATV-like 1). The presence of some of these viruses across numerous regions in the world could have several explanations, including i) a long-term association between those viruses and R. microplus and ii) a consequence of livestock historical trade. Our results shed new light on the virus diversity of this tick species and provide a basis for further studies on the evolutionary history and pathogenic potential of these interesting viruses.

Abstract
Tick-borne viruses have emerged recently in many parts of the world, and the discoveries of novel tick-borne viruses have been accelerated by the development of high-throughput sequencing technology. In this study, a cost-efficient small benchtop next-generation sequencer, the Illumina MiniSeq, was used for the RNA virome analysis of questing ticks collected from Hokuriku District, Japan, and assessed for their potential utility in a tick-borne virus surveillance system. We detected two phleboviruses [Kabuto Mountain virus (KAMV) and Okutama tick virus (OKTV)], a coltivirus [Tarumizu tick virus (TarTV)], and a novel iflavirus [Hamaphysalis flava iflavirus (HfIFV)] from tick homogenates and/or cell culture supernatants after virus isolation processes. The number of sequence reads from KAMV and TarTV markedly increased when cell culture supernatants were used, indicating a successful isolation of these viruses. In contrast, OKTV and HfIFV were detected only in tick homogenates but not from cell culture supernatants, suggesting a failure to isolate these viruses. Furthermore, we performed genomic and phylogenetic analyzes of these detected viruses. OKTV and some phleboviruses discovered recently by NGS-based methods were probably deficient in the M genome segment, which are herein proposed as M segment-deficient phlebovirus (MdPV). A phylogenetic analysis of phleboviruses, including MdPV, suggested that Uukuniemi and Kaisodi group viruses and kabutoviruses evolved from an ancestral MdPV, which provides insights into the evolutionary dynamics of phleboviruses as emerging pathogens.
