In the present study the role of soluble CD14, L-Fucose and Sialic acid, in increasing the immunity in breastfed infants were studied to establish the previously unrecognized function and their broader spectrum of activities. Approach: The study was carried out with three different groups of breastfed neonates/infants; In group-I twenty full term neonate aging from (1-29 days), group-II fifteen pre-term neonates aging from (1-29 days) and in group-III fifteen infants aging from (61-730 days) were selected and their health were studied. Results: The results showed that the levels of sCD14 were 16.47 ± 5.50, 17.07 ± 5.86 and 15.10± 3.45 µg mL-1 in full term, pre-term and 2-years group respectively. The levels of sialic acid were 2.5-3 folds higher in group-I (3.29±1.34 mmol L-1) and group-II (3.99 ± 1.32 mmol L-1), as compared to group-III (1.30 ± 0.16 mmol L-1) repectively. Similarly, the level of L-Fucose was 1.5 folds higher in group-I (8.84 ± 0.34 mmol L-1) and group-II (8.92 ± 0.37 mmol L-1) as compared to group-III (5.80 ± 1.96 mmol L-1). Conclusion: Breast milk contains a variety of antimicrobial substances (relatively resistant against intestinal proteolysis) that functions in safeguarding the lactating mammary gland and provides protection to the suckling infant at a time when its immune system is still immature, some of these substances include sCD14, Sialic acid and L-Fucose. Hence, it is recommended to breastfeed the neonates/infants to enhance their immunity.}, journal = {American Journal of Biochemistry and Biotechnology}, publisher = {Science Publications} }
