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

The bifidus factor in human milk promotes the growth of *Lactobacillus bifidus*, a beneficial gut bacterium that helps in maintaining intestinal health and protecting infants against harmful pathogens. This factor enhances the germicidal properties of human milk by creating an acidic environment unfavorable for pathogenic bacteria. It plays a critical role in building an infant’s immunity.
