Mother-child relation in human schistosomiasis mansoni : skin test and cord blood reactivity to schistosomal antigens.
Reaction to schistosomal antigen was studied in children born to mothers infected with Schistosoma mansoni. Values of immediate (15 min) skin reactions were more elevated and values of delayed (24 h) skin reactions were significantly higher in children born to infected mothers than in children born to uninfected mothers. The macrophage migration inhibition test, done on cord blood cells, was positive to schistosomal antigen in 40% of children born to infected mothers and negative in all children born to uninfected mothers. These results suggest prenatal sensitization to schistosomal antigen in children born to mothers infected with S. mansoni.
