This according to researchers from University of Texas Medical Branch who examined genetic samples taken from 505 children in Texas and Kentucky.
Otitis media runs in families with certain gene abnormalities
The tendency to get otitis media runs especially in families where three important genes producing inflammatory signalling molecules for the immune system are â€˜corruptedâ€™ by abnormalities caused by so called SNPâ€™s (single-nucleotide polymorphisms).
The researchers found that the breast-fed children with abnormalities in those genes actually were protected from recurrent ear infections (otitis media).
