One potential factor is sociality. In social organisms such as ants, the interaction between hosts and viruses might differ from those of solitary organisms due to their unique ecology. We previously isolated a double-stranded RNA toti-like virus, Camponotus yamaokai virus (CYV), from the arboreal ant <i>Camponotus yamaokai</i>. The ant exhibits a polygynous colony structure with multiple queens and within-nest mating behaviors. Such unique ecological traits may have driven the evolution of a distinctive relationship with the virus. However, the biological characteristics of CYV have not been sufficiently studied. In this study, we investigated the biological characteristics of CYV through rearing experiments and field surveys. No horizontal transmission between workers and broods was detected, and there were no significant differences in prevalence between castes. CYV was detected at all seven locations surveyed, with prevalence ranging from 60–95%. The high CYV prevalence across the host's distribution range indicates that the geographical distribution of CYV aligns with that of its host. These results suggest that CYV has spread throughout the host population, primarily through vertical transmission.</p></div>","PeriodicalId":8359,"journal":{"name":"Archives of Virology","volume":"170 5","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143835661","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We investigated the transmission route and distribution of the H5N6 virus in the largest live-poultry market (LPM), which is linked to the human infection. A total of 1357 samples from the LPM were collected for avian influenza A virus detection from 2020 to 2023. The proportion of LPM samples positive for H5 subtype avian influenza virus was 14.30% (194/1357). Sequences of H5N6 (n = 10) and H5N1 (n = 4) avian influenza viruses were obtained from the LPM samples using next-generation sequencing. The complete genome sequence of the H5N6 virus from the human infection case, A/Changsha/1/2022(EPI_ISL_16466440), was determined and analyzed. The PB1 and PB2 segments shared 99.65% and 99.23% sequence identity with A/duck/Hunan/S40199/2021(H5N6) and A/Whooper swan/Sanmenxia/H615/2020(H5N8), respectively. The other segments showed the highest sequence similarity to strain A/Guangdong/1/2021(H5N6), which was isolated in Guangzhou. L89V and I292V substitutions in the PB2 protein were predicted from the A/Changsha/1/2022 genome sequence. Phylogenetic analysis based on the HA gene showed that A/Changsha/1/2022 and other H5 subtype isolates obtained from the LPM grouped together in the 2.3.4.4b branch. Bayesian evolutionary analysis of the HA gene showed that clade 2.3.4.4b of the H5N6 virus is likely to have been prevalent in Hunan Province around October 2021. In conclusion, we confirmed that the clade 2.3.4.4b HA gene of A/Changsha/1/2022 virus recombined with those of local strains. These results demonstrate the importance of continuous surveillance of H5N6 influenza viruses.</p></div>","PeriodicalId":8359,"journal":{"name":"Archives of Virology","volume":"170 5","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143809265","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It exhibits marked genetic variability, which is affected by factors such as vaccination and commercial trade. In this study, a retrospective analysis of PCV2 was performed based on molecular characterization, Bayesian inference, and haplotype networks in tissue samples obtained from Brazilian pig herds from 1967 to 2018. A nested PCR targeting a 225-nucleotide fragment of the PCV2 capsid gene was performed, followed by bidirectional sequencing. Out of 178 samples tested, 39 (21.9%) were positive for PCV2. Phylogenetic analysis showed that strains from this study collected before the introduction of a PCV2 vaccine clustered with genotype 2d reference strains. The mean substitution rate was 1.54 × 10<sup>-3</sup> substitutions per site per year (s/s/y). The haplotype diversity of PCV2 was 0.98, which shows a high mutation rate compatible with the topology found in the haplotype network. Our study shows that most of the Brazilian isolates, including those obtained before the introduction of the PCV2 vaccine, were similar to PCV2d reference strains, suggesting that this genotype was already circulating before the introduction of the vaccine in Brazil. One of the PCV2 sequences was from an isolate from 1967, making it the oldest sequenced isolate from the Americas, and the second oldest worldwide. Phylogenetic analysis and haplotype network analysis indicated a high degree of diversity of PCV2 as well as a high rate of evolution. These results increase our knowledge about the genetic diversity, evolution, and dispersal patterns of PCV2 in Brazil.</p></div>","PeriodicalId":8359,"journal":{"name":"Archives of Virology","volume":"170 5","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143809264","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
