Protective effects of breastfeeding against urinary tract infection.

UNLABELLED: Protective factors in human milk act on mucosal membranes in the upper and lower respiratory tract and in the gastrointestinal tract. The way in which breastfeeding may reduce the risk of infections in a more remote site such as the urinary tract will be elucidated. CONCLUSION: The protective effect of breastfeeding on the urinary tract illustrates the complexity of the immune defence mechanisms responsible for such an action.
