Introduction: new page 1 Taiwan Institute of animal science and technology has successfully developed enteric microcapsule oral vaccine for animals by using nano encapsulation technology, in which antigens for animals are encapsulated This kind of vaccine is not only faster than the traditional injection, but also cheaper and more effective The principle of AG6 technology is similar to that of crystal ball yoghurt, which encapsulates beneficial bacteria in the crystal ball, so that it is not affected by gastric acid, and is better absorbed in the intestine The new oral vaccine particles are small, about 100 microns Weng Zhongnan, director of AG6 Taiwan Institute of zoology, pointed out that Pathogenic E.coli, Salmonella cholerae, Actinobacillus pleuropneumoniae and Pasteurella suis are common bacterial infectious diseases in Taiwan's pig industry General injection vaccine can not achieve effective epidemic prevention effect, and can only use pig farm management and drug control to achieve the prevention and control purpose However, long-term dependence on antibiotics may cause resistance of pathogens, so vaccines must be used instead He also said that the microcapsule oral vaccine is mucosal immunity, which can produce an immune response in four to five days, and the price of IgA antibody produced in two weeks is at least 10 times higher than that of the injection vaccine AG6
