To better understand the prevalence and genetic diversity of RVAs among pigeon flocks in China, a fluorescence quantitative RT-PCR assay for detection of RVAs was developed in this study. The fluorescence quantitative RT-PCR assay showed satisfactory specificity, sensitivity, repeatability, and reproducibility, with a limit of detection (LOD) of 1 \u00d7 102 copies\/\u03bcL for RVA. Then, 645 pigeon swab samples collected from live bird markets in 10 provinces of China from 2023 to 2024 were tested for RVA with the fluorescence quantitative RT-PCR assay established in this study to characterize the current epidemiological status of pigeon-origin RVAs (PiRVAs). The results showed that the PiRVA positivity rate detected by the RT-qPCR assay was 12.24% (79\/645) among pigeon flocks in China. Guizhou Province had the highest positive rate of PiRVAs (42.86%) among the 10 provinces sampled. The VP7 and VP4 gene of nine representative positive pigeon RVA samples were amplified by specific primers, and the phylogenetic analysis of these samples revealed that all RVAs among pigeons belonged to the G18P[17] genotype, though with certain genetic variations. This study established a useful tool for diagnosing Pigeon RVAs in practice, and provided valuable information to better understand the epidemiology of Pigeon RVAs among pigeon flocks in China.<\/jats:p>","DOI":"10.3390\/v18060640","type":"journal-article","created":{"date-parts":[[2026,6,3]],"date-time":"2026-06-03T09:33:14Z","timestamp":1780479194000},"page":"640","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Development and Application of a Fluorescence Quantitative RT-PCR Assay for Detection of Group A Rotavirus Among Pigeons in China from 2023 to 2024"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0555-8727","authenticated-orcid":false,"given":"Xiaohui","family":"Yu","sequence":"first","affiliation":[{"name":"China Animal Health and Epidemiology Center, Qingdao 266032, China"},{"name":"Key Laboratory of Animal Biosafety Risk Prevention and Control (South China), Ministry of Agriculture and Rural Affairs, Qingdao 266032, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-9003-0374","authenticated-orcid":false,"given":"Cuiyao","family":"Zhang","sequence":"additional","affiliation":[{"name":"China Animal Health and Epidemiology Center, Qingdao 266032, China"},{"name":"College of Animal Science and Technology, Shandong Agricultural University, Taian 271018, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lu","family":"Chen","sequence":"additional","affiliation":[{"name":"China Animal Health and Epidemiology Center, Qingdao 266032, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jingjing","family":"Wang","sequence":"additional","affiliation":[{"name":"China Animal Health and Epidemiology Center, Qingdao 266032, China"},{"name":"Key Laboratory of Animal Biosafety Risk Prevention and Control (South China), Ministry of Agriculture and Rural Affairs, Qingdao 266032, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yufeng","family":"Liu","sequence":"additional","affiliation":[{"name":"China Animal Health and Epidemiology Center, Qingdao 266032, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuteng","family":"Chen","sequence":"additional","affiliation":[{"name":"China Animal Health and Epidemiology Center, Qingdao 266032, China"},{"name":"College of Animal Science and Technology, Shandong Agricultural University, Taian 271018, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jinping","family":"Li","sequence":"additional","affiliation":[{"name":"China Animal Health and Epidemiology Center, Qingdao 266032, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guangyu","family":"Hou","sequence":"additional","affiliation":[{"name":"China Animal Health and Epidemiology Center, Qingdao 266032, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shuang","family":"Chang","sequence":"additional","affiliation":[{"name":"College of Animal Science and Technology, Shandong Agricultural University, Taian 271018, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Leilei","family":"Sun","sequence":"additional","affiliation":[{"name":"New Hope Liuhe Co., Ltd., Jinjiang Industrial Park, No. 376, Jinshi Road, Chengdu 610063, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yang","family":"Li","sequence":"additional","affiliation":[{"name":"China Animal Health and Epidemiology Center, Qingdao 266032, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,6,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Johne, R., Schilling-Loeffler, K., Ulrich, R.G., and Tausch, S.H.
