 en IgA1 levels in milk and serum samples from intestinal parasite-infected or normal puerperae
Manhani, Marianna Nascimento; Cruz, Julia Maria Costa; Ferreira, Daniela Marques de Lima Mota; Abdallah, Vânia Olivetti Steffen & de Souza, Maria Aparecida


In this study, IgA1 levels in the milk and serum of puerperae were compared and a correlation was established between the levels of this immunoglobulin and the occurrence of parasitism. Eighty-three paired milk and serum samples were obtained from puerperal and IgA1 levels were analyzed. In addition, the presence of intestinal parasites in stool samples from these puerperae was determined. Twelve puerperae tested positive for intestinal parasites and all their samples presented an IgA1 ELISA Index > 1. There was a correlation between serum and milk IgA1 levels and puerperae with any parasite in their stool (r = 0.6723; p = 0.0166). This finding may reinforce the importance of breast-feeding for the protection of neonates.
