| Sumario: | ABSTRACT. Natural additives have become one of the most alternative immune enhancer nowadays. In particular, Spirulina platensis (Arthrospira platensis) (SP) and Saccharomyces cerevisiae (SC) have been used for improving the immune system and quality of life. The aim of this study was to regulate the immune effect of S. cerevisiae and S. platensis (A. platensis) combination. Forty male New Zealand white rabbits, aged 5-6 weeks, were analysed in 4 groups: Control (basal diet); SC (added 3 g/kg diet), SP (added 5% of the diet); SC and SP (added 3 g/kg SC and 5% SP of the diet). The entire experiment lasted 90 days. Blood samples were obtained by ear venipuncture on the 90th day. The CD4+ and CD8+ T lymphocyte values were determined by flow cytometry and cytokines (IFN-γ and IL-4) were determined by ELISA. According to the results, there were no significant differences in the expression of cytokines, but serum CD4+/CD8+ increased in the animals fed SP and SC+SP supplemented diets (3 g/kg and 5% of the diet, respectively). It was concluded that S. platensis (A. platensis) may be used as an immune enhancer, although further studies are needed to clarify the effects of spirulina supplement on immunity. |
