– We found that the nucleotide sequences of genes encoding STa, STb and LT toxins of ETEC strains isolated from piglets in Vietnam were highly homologous and stable.
– We have synthesized the recombinant gene (sls gene) which encoding recombinant enterotoxin fusion protein (STa – LTB –STb) and then, sls gene was inserted into pDrive and transformed into DH5α E. coli strain.
– We have created E. coli BL21 strain which can express recombinant enterotoxin fusion protein.
– This is first time in Vietnam successfully produce recombinant subunit vaccine for preventing diarrheal disease in postweaning piglets cause by ETEC bacteria.
