this research established a solid foundation to find new method of detecting app such as elisa, pcr etc and produce an actinobacillus pleuropleumoniae genetic engineering vaccine strain effective.
as many indices of immunofunction have changed after the treatment by the vaccine, we induce that the somatostatin genetic engineering vaccine may affect the immuno-function via some hormones.
the results in this experiment are very important for further study on development of genetic engineering vaccine against rabies and on the investigation of molecular epidemiology of rabies virus.
