Document Summary

Leukocytes, also known as white blood cells, are a cellular component of the blood that has a nucleus, absence of hemoglobin, and is capable of motility. They are part of the immune system and help to defend the body against infection and diseases by destroying cancer cells and infection agents, ingesting foreign materials and cellular debris, and producing antibodies. Leukocytes are produced by bone marrow and found in the blood and lymph tissue, spleen, liver, and kidney, which help in the regulation of leukocyte production levels. The normal value of white blood cells ranges from 4000-11000 per microliter. Leukocytes belong to at least five different categories and are distinguishable by their size, nuclear shape, and cytoplasmic inclusion. Different types of leukocytes are involved in different functions. Some recognize intruders, some kill harmful bacteria, and some synthesize antibodies to protect the body against exposure to microorganisms (bacteria, viruses, and fungi).

I find it facinating that humans can suffer from an amoebainfestation. Amoeba must reproduce far more slowly than bacteria.In size, they seem to be approximately the same size as the variousleukocyte cell types (I see estimates ranging from 10?m to 30?m indiameter). I would assume that they are slow-moving, or, at leastno more motile than a leukocyte.

How is it, then, that a population of amoeba can take upresidence (and a particularly dangerous one, at that) in a humanbody without them being wiped out by the immune system? Do we knowmuch about the pathology of such an infection? Do the amoebaactually consume the leukocytes by phagocytosis before they can beconsumed themselves?
