The genes fusion cassettes were exchanged to chromosomal loci of Typhimurium SL3261 parental strain produced approximately a 2,700 bp of DNA fragment (Fig. of immune responses. Results Our NRSL32 strain showed expression and secretion of SspH21-215-LipL32 recombinant protein via SPI-2 T3SS. After oral administration of NRSL32 strain to rats, significant titers of total Doramectin immunoglobulin Doramectin G (IgG) and immunoglobulin A against rLipL32 were observed in long period up to 77 days after vaccination. The stimulated antibody showed ability to specific bind with LipL32 protein on surface of pathogenic spp. Additionally, the balance level of IgG2a/IgG1 ratio and level of…
