The genomic features and epidemiological trends of these strains remain to be elucidated.</p><p><strong>Results: </strong>To evaluate the prevalence of NADC30-like PRRSV in China, this study acquired 30 whole-genome sequences of NADC30-like strains via Next-Generation Sequencing (NGS).

A comprehensive analysis of the genomic characteristics of contemporary NADC30-like PRRSV strains in China was conducted.

An important aspect when considering the toxicity of DON is the occurrence of its modified forms, which can be transformed into DON in the digestive system. The toxic effect of DON can also be caused by other mycotoxins which co-occur in cereals. The toxic effect of DON on the body of pigs was observed mainly in the digestive, immune, and reproductive systems. The noticeable of DON's toxic effects depends on the exposure time, route of administration and mycotoxin concentration. The changes are mainly caused by impaired gene expression, inhibiting protein synthesis or the effect of DON on pathways in pigs' bodies. The negative impact of DON on the health of pigs may lead to reduced weight gain, poor health, and increased susceptibility to infections and reproductive disorders. There have also been many methods of DON elimination from cereals, but their efficiency is insufficient.</p>","PeriodicalId":20352,"journal":{"name":"Porcine Health Management","volume":"11 1","pages":"27"},"PeriodicalIF":3.0,"publicationDate":"2025-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12066055/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143978974","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
