    Normal mammalian sera possess a heat-labile opsonin system crucial for phagocytosis by immune cells. This system plays a vital role in the early stages of acute bacterial infections against various microbes.

    Area of Science:

    • Immunology
    • Microbiology

    Background:

    • Normal mammalian sera contain a heat-labile opsonin system.
    • This system enhances phagocytosis of microorganisms by polymorphonuclear leukocytes.
    • It is present in non-immune sera and acts broadly against diverse microbes.

    Purpose of the Study:

    • To discuss the factors involved in the heat-labile opsonin system.
    • To explore the in vivo significance of this system in host defense.

    Main Methods:

    • The abstract does not specify methods but implies discussion and analysis of existing knowledge.

    Main Results:

    • The heat-labile opsonin system is a key component of innate immunity.
    • It facilitates the clearance of various microorganisms.
