Mother-child relationship in human schistosomiasis mansoni. I. Parasitic antigens and antibodies in milk.
Immunoglobulins, anti-Schistosoma mansoni antibodies, complement components and schistosome antigens were investigated in milk from mothers infected with S. mansoni. No significant differences of immunoglobulins or complement component levels were observed between infected and control mothers. Anti-S. mansoni antibodies were detected in the milk of 8 out of 25 infected mothers. A significant relationship was observed between serum and "4", were demonstrated in milk from infected patients by the double diffusion micromethod. The function of these immunologically active substances transmitted by milk from mother to child is discussed.
