In contrast, PMN quickly became immobilised when interacting with biofilms. Very few PMN were able to phagocytise young (6 h) and mature (24 h) biofilms, suggesting that the accumulation of matrix components quickly provides a protective effect. Biofilms lacking either eDNA or PIA were much less dense, and many more PMN were able to phagocytise bacteria in these biofilms.

Genomic analysis of BSXE-2102 unveiled multiple genes responsible for the biosynthesis of 12 secondary metabolites, indicating its potential in combating pathogens. The identification of stress tolerance and adhesion-related genes suggested that BSXE-2102 has the ability to survive and colonize the host environment. The presence of numerous genes involved in the metabolism of carbohydrates, lipids, and amino acids, as well as the biosynthesis of 13 amino acids, 5 organic acids, and 7 vitamins, highlighted its role in food digestion and nutrition provision. Additionally, genes related to immune stimulation were identified, underscoring its potential immunomodulatory effects. Safety assessments, including antibiotic resistance tests, hemolytic assays, and genomic analyses, indicated that BSXE-2102 was sensitive to all antibiotics tested and did not carry high-risk antibiotic resistance genes. The strain also exhibited no hemolytic activity and lacked high-risk virulence factor-coding genes. The <em>in vivo</em> feeding experiment demonstrated that dietary supplementation with BSXE-2102 (at concentrations of 1 × 10<sup>5</sup>, 1 × 10<sup>6</sup>, 1 × 10<sup>7</sup>, and 1 × 10<sup>8</sup> CFU/g) improved growth performance, enhanced 8 serological immune parameters, upregulated the expression levels of 8 hepatopancreatic immune-related genes, and increased resistance against <em>Vibrio parahaemolyticus</em> of <em>Penaeus vannamei</em> to varying degrees.
