HIGHLIGHTS E. coli BL21 as a suitable expression and delivery vaccine system; rSeM protein protect mice against S. equi infection; cells enhance the immune response equi; protein, purified or not, presented immunogenicity in horses.

ABSTRACT: The aims of this study were: 1) determine total specific IgG and subisotypes in serum colostrum pregnant mares vaccinated against Theileria equi Streptococcus subspecies equi; 2) foals born from these mares. In mares, the highest value for T. was at 335 days gestation declining 30 postpartum, while S. 328 remaining high up to postpartum. Transfer passive immunity both antigens observe...
