Question

In human milk, the major factor concerned for germicidal action is:

• A. Lysozyme
• B. Leucocytes
• C. Complement
• D. Bifidus factor

Hint:

Human milk is naturally fortified with components that boost an infant’s immunity, including bifidus factor and lysozymes.

Answer 1

The Correct Option is D

Human milk's bifidus factor promotes the growth of *Lactobacillus bifidus*, a beneficial gut bacterium crucial for infant intestinal health and protection against pathogens. This factor enhances milk's germicidal properties by creating an acidic environment hostile to pathogenic bacteria, thus playing a critical role in an infant's immune development.
