Which type of antibody present in colostrum

The correct answer is IgA

Explanation:

• Colostrum is the first form of milk produced immediately following the delivery of the newborn.
• It is rich in antibodies, especially IgA, which play a crucial role in providing immunity to the newborn during the first few days of life.
• IgA antibodies are essential for mucosal immunity and are found in high concentrations in colostrum.
• It plays a significant role in protecting the mucous membranes lining the respiratory and gastrointestinal tracts. By providing passive immunity, IgA helps to safeguard the newborn from infections during the early stages of life.

Other Options:

• IgG: While Immunoglobulin G (IgG) is the most common antibody in blood and extracellular fluid, providing long-term protection. IgG is mainly transferred to the newborn through the placenta during pregnancy.
• IgM: Immunoglobulin M (IgM) is the first antibody to respond to an infection and is primarily found in the blood and lymphatic fluid.
• IgE: Immunoglobulin E (IgE) is associated with allergic reactions and is found in very small amounts in the body.
