Predominance of gastrointestinal protozoan parasites in children: A brief review

Intestinal parasitic infections are among the major diseases of concern to public health throughout the world [1]. About 25% of world’s population suffers from one or more kinds of intestinal parasitic infections (helminthes/protozoa). Children because of their complex nutritional requirements and less developed immune systems are observed to be the principal sufferers of these parasitic infections [2]. Moreover, they have an extremely delicate physiology which can result in severe upsetting of their biochemical and physiological processes associated with these infections. Intestinal protozoan parasites can affect children in a variety of ways; they cause mal-absorption, reduced growth, increased risk for protein energy malnutrition, reduced psychomotor development and anemia. This report addresses Cryptosporidium, Giardia, and Entamoeba as the main parasitic protozoa of concern among children worldwide.
