Aeromonas veronii and application thereof

The invention relates to the technical field of microorganisms. Specifically, the invention relates to an aeromonas veronii, which is preserved in Guangdong Microbial Culture Collection Center on December 1, 2023, the preservation number is GDMCC No: 64099, and the preservation address is the 5th floor, No. 59 building, No. 100 Courtyard, Xianlie Middle Road, Guangzhou. The aeromonas veronii is good in immunogenicity and strong in pathogenicity, and the vaccine prepared on the basis of the aeromonas veronii has the advantages of being low in immune dosage, high in immune protection rate, long in immune duration, good in immune cross protection on other current epidemic aeromonas veronii strains and the like, and has very high application value. 本发明涉及微生物技术领域。具体而言，本发明涉及一株维氏气单胞菌，其于2023年12月1日保藏于广东省微生物菌种保藏中心，保藏号为GDMCC No:64099，保藏地址为广州市先烈中路100号大院59号楼5楼。该维氏气单胞菌的免疫原性好、致病性强，基于其制备得到的疫苗的具有免疫剂量低、免疫保护率高、免疫持续期长且对当前流行的其他维氏气单胞菌株具有较好的免疫交叉保护等优点，具备很高的应用价值。
