Therefore SIgA are mainly directed against previous recent Thus breastfeeding modulates early neonate's mucosa limits bacterial translocation through mucosa. This may be a major reason why protects efficiently neonatal septicaemia, as well several other infections. prevent infections already mucosal level. transplacentally obtained maternal IgG protect primarily in tissues do so cost cytokine-induced clinical symptoms, tissue engagement high energy consumption.
