The present invention relates to intranasal bacterial polysaccharide conjugate nanoemulsion vaccines and methods of using the same for inducing an immune response to a bacterial polysaccharide.

This invention relates to the field of veterinary drug product technology, and more specifically, to a veterinary vaccine enhancer and its preparation and application. The veterinary vaccine enhancer comprises, by weight, the following components: 20-30 parts bacterial polysaccharide, 20-30 parts astragalus polysaccharide, 10-20 parts saponin, 4-12 parts vitamin B and C compound additive, and 1-5 parts polyethylene glycol 1000. The vaccine prepared using this invention is stable, safe, has high antibody titers, rapid antibody production, and long-lasting immunity, exhibiting excellent overall performance. The preparation method of the veterinary vaccine enhancer of this invention is simple, convenient, and low-cost, suitable for large-scale production and widespread application.

The application provides a method for efficiently and rapidly removing Microcystis aeruginosa and CTAB by using bacterial polysaccharide, comprising the following steps: (1) mixing CTAB with a water sample to be treated to obtain a mixed solution, and culturing together, wherein the water sample to be treated contains Microcystis aeruginosa; (2) adding bacterial polysaccharide into the mixed solution of Microcystis aeruginosa and CTAB obtained in the step (1), and mixing uniformly to flocculate the Microcystis aeruginosa and CTAB; and (3) separating the flocculation of the bacterial polysaccharide, Microcystis aeruginosa and CTAB obtained in the step (2) through a 30-mesh sieve. The positively charged CTAB is adsorbed on the negatively charged Microcystis aeruginosa and bacterial polysaccharide, and the CTAB is removed by collecting the microalgae flocculation. The Microcystis aeruginosa and CTAB in water can be removed by the method.
