Colostrum, serum and saliva were simultaneously obtained from 50 normal mothers. 19-45 years old, 36-72 hours post-delivery. Total IgA level and class-IgA antibodies against 3 common food antigens (lactoglobulin, gliadin and ovalbumin) and 4 types of salmonella (typhi, paratyphi A, B and C) were determined in all samples. The 7 antibodies (Ab) were detected in colostrum, by ELISA, in a higher percentage of samples (88-62%), than in serum (82-34%) and saliva (77-27%). These percentages were higher for food-Ab than for anti-salmonella Ab. The total colostral IgA was close correlated with food-Ab in colostrum (p less than 0.001) and quite poorer with anti-salmonella Ab (p less than 0.05-p less than 0.01). A good correlation was generally also present between Ab from colostrum/serum, but was worse between both secretions (colostrum/saliva). The present results suggest that colostrum specific Ab levels can be predicted, depending on total IgA and the specific Ab from serum.

UI MeSH Term Description Entries
D007070 Immunoglobulin A Represents 15-20% of the human serum immunoglobulins, mostly as the 4-chain polymer in humans or dimer in other mammals. Secretory IgA (IMMUNOGLOBULIN A, SECRETORY) is the main immunoglobulin in secretions. IgA,IgA Antibody,IgA1,IgA2,Antibody, IgA
D011247 Pregnancy The status during which female mammals carry their developing young (EMBRYOS or FETUSES) in utero before birth, beginning from FERTILIZATION to BIRTH. Gestation,Pregnancies
D003126 Colostrum The thin, yellow, serous fluid secreted by the mammary glands during pregnancy and immediately postpartum before lactation begins. It consists of immunologically active substances, white blood cells, water, protein, fat, and carbohydrates. Colostrums
D004797 Enzyme-Linked Immunosorbent Assay An immunoassay utilizing an antibody labeled with an enzyme marker such as horseradish peroxidase. While either the enzyme or the antibody is bound to an immunosorbent substrate, they both retain their biologic activity; the change in enzyme activity as a result of the enzyme-antibody-antigen reaction is proportional to the concentration of the antigen and can be measured spectrophotometrically or with the naked eye. Many variations of the method have been developed.
