A recent study conducted at Jilin Agricultural University in Changchun, People's Republic of China, focused on developing a vaccine to prevent largemouth bass virus (LMBV) infections, which can be detrimental to the aquaculture industry. Researchers successfully created a recombinant Lactobacillus plantarum strain expressing the MCP gene of LMBV, which showed promising results in increasing largemouth bass resistance to the virus. The study suggests that this recombinant bacterium could serve as an effective oral vaccine to prevent LMBV infections in largemouth bass. [Extracted from the article]
