However, the detection results of environmental swabs cannot always reflect the accurate status of viral pollution, leading to persistent ASFV environmental contamination. In this study, we developed an ASFV eluant with higher environmental ASFV detection efficiency relative to 0.85% saline solution, which obtains the patent certificate issued by the China Intellectual Property Office (patent number:202010976050.9). qPCR analysis showed that in the environmental swab samples, the number of viral copies was 100 times higher for the ASFV eluant treatment than the traditional eluant treatment (0.85% saline solution). And besides, the high sensitivity of the ASFV eluant had be verified in a slaughterhouse environmental sampling detection. In soil samples, the ASFV eluent showed the same extraction effect as the TIANamp Soil DNA Kit, in contrast to no extraction effect for 0.85% saline solution. Simultaneously, this eluent could protect ASFV from degradation and allow the transportation of samples at ambient temperature without refrigeration. In clinical practice, we monitored the environmental contamination condition of the ASFV in a large-scale pig farm. The results shown that the ASFV load decreased after every disinfection in environment. This study provides an effective solution for surveilling the potential threat of ASFV in environment.<\/jats:p>","DOI":"10.1186\/s13568-024-01697-1","type":"journal-article","created":{"date-parts":[[2024,5,10]],"date-time":"2024-05-10T17:02:05Z","timestamp":1715360525000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["A novel easy-to-desorb eluant contributes to address environmental contamination of African swine fever virus"],"prefix":"10.1186","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2100-2692","authenticated-orcid":false,"given":"Li","family":"Zhang","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pengfei","family":"Zhao","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yingjun","family":"Xia","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yanli","family":"Hu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chaofei","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rui","family":"Fang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Junlong","family":"Zhao","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2024,5,10]]},"reference":[{"key":"1697_CR11","doi-asserted-by":"crossref","unstructured":"Albert M, Science L, Technology SJW (1991) Recovery of Enterovirus from primary sludge using three Elution concentration procedures. 24:225\u2013228","DOI":"10.2166\/wst.1991.0063"},{"key":"1697_CR1","doi-asserted-by":"publisher","first-page":"2830","DOI":"10.3389\/fmicb.2019.02830","volume":"10","author":"J Bai","year":"2019","unstructured":"Bai J, Lin H, Li H, Zhou Y, Liu J, Zhong G, Wu L, Jiang W, Du H, Yang J, Xie Q, Huang L (2019) Cas12a-Based On-Site and Rapid Nucleic Acid Detection of African Swine Fever.
