Abstract:
The present invention relates to a detection method using magnetic nanoparticles for rapidly isolating Mycobacterium avium subsp. paratuberculosis from fecal samples and, more specifically, to a method for detecting the Mycobacterium avium subsp. paratuberculosis which isolates the Mycobacterium avium subsp. paratuberculosis with high sensitivity which can be existed in animal fecal samples using the magnetic nanoparticles to which Mycobacterium avium subsp. paratuberculosis specific antibodies are combined and rapidly and simply checks infection of the Mycobacterium avium subsp. paratuberculosis by performing polymerase chain reaction using primers which are specifically combined to DNA of the Mycobacterium avium subsp. paratuberculosis. According to the present invention, the detection method using the magnetic nanoparticles for rapidly isolating the Mycobacterium avium subsp. paratuberculosis from fecal samples can easily detect the Mycobacterium avium subsp. paratuberculosis even if small number of the Mycobacterium avium subsp. paratuberculosis is existed in biological samples such as feces and prevent contagion to different entities by isolating the infected entities from an allied army by performing the method simply and rapidly.

An immune enhancer, vaccine adjuvant additive, auxiliary therapeutic agent and feed additive comprises a Zygosaccharomyces bailii lysates. A method for manufacturing the Zygosaccharomyces bailii lysate comprises: a step of culturing the Zygosaccharomyces bailii in the media at 26‹C for 72 hours; a step of centrifuging the cultured media and suspending in phosphate buffered saline (PBS); a step of adding dissolution agent and stirring at room temperature for two to three days; a step of adjusting pH concentration to 6.5-7.2; and a step of drying and maintaining in a thermostatic chamber.
Abstract:
Provided is an immunostimulant using dandelion extract which improves a function of a nonspecific defense against pathogen and increases activity of animal immunocytes such as neutrophil and macrophages. An immunostimulant using dandelion extract comprises dandelion extract obtained by a hot water process as an active ingredient. A method for preparing the immunostimulant comprises a steps of extracting the dandelion extract at a temperature of 90~100°C by hot distilled water. The dandelion extract can be used independently or with additives which are generally used.
Abstract:
An exo-polysaccharide derived from a Saccharomyces spp. strain is provided to enhance various activities of neutrophil, macrophage and lymphocyte, thereby being widely applied to an animal immunity-enhancing agent, a vaccine supplemental additive and an adjuvant therapeutic agent. An animal immunity enhancing agent comprises exo-polysaccharides extracted from a culture material of a Saccharomyces spp. strain. A method for preparing the exo-polysaccharides derived from the Saccharomyces spp. strain comprises the steps of: (a) after suspending pure colonies obtained by culturing the Saccharomyces spp. strain in sterile saline solution, inoculating 1 ml of the suspension into 1,000 ml of yeast malt broth and culturing it at a temperature of 28 deg.C for 72 hours; (b) after adding two times amount of distilled water into a culture material obtained from the step(a) and mixing it, boiling the mixture at a temperature of 100 deg.C for 1 hour and centrifuging the boiled mixture under 5,000xg for 30 minutes to collect supernatant therefrom; and (c) after adding two times amount of ethyl alcohol to the supernatant and mixing it, leaving a mixture in a cool chamber at a temperature of 4 deg.C for 2 days and collecting precipitated polysaccharides therefrom.
Abstract:
A plate agglutination tester and a method for measuring an immuno-reaction using the same are provided to decrease error of the result analysis in accordance with proficiency of a person performing diagnosis, show the degree of various immuno-reactions in an objective value and perform various statistical analyses, thereby being very useful for measuring the immuno-reaction. A plate agglutination tester consists of a transparent film and is characterized in that a section, which consists of a plurality of circles and where an antigen-antibody agglutination reaction occurs, is arranged and formed in horizontal and vertical directions on an upper side of the film. A method for measuring an immuno-reaction comprises the steps of: (a) mixing an antigen and an antibody specifically bound to the antigen with the plate agglutination tester to induce an agglutination reaction; (b) scanning the agglutination reaction induced plate agglutination tester and converting a scanning result into an image file; and (c) analyzing the obtained image file using a computer program capable of detecting fine agglutination reactants to numberize the intensity of the agglutination reaction. Further, the transparent film is an over head project film.
