The protective effect of breast milk is known to be associated with: (LQ)



A IgM antibodies
B Lysozyme

C Mast cells
D IgA antibodies

Ans. D

IgA antibodies

1. Both Lysozyme (secreted by macrophages present in breast milk) & Ig A antibodies are important for protective effect. However, IgA antibodies is more important.

2. All have been found in human milk, but by far the most abundant type is IgA, specifically the form known as secretory IgA, which is found in great amounts throughout the gut and respiratory system of adults.

3. These antibodies consist of two joined IgA molecules and a so-called secretory component that seems to shield the antibody molecules from being degraded by the gastric acid and digestive enzymes in the stomach and intestines.

4. Infants who are bottle-fed have few means for battling ingested pathogens until they begin making secretory IgA on their own, often several weeks or even months after birth.

The secretory IgA molecules passed to the suckling child are helpful in ways that go beyond their ability to bind to microorganisms and keep them away from the body's tissues.
