MICROANATOMY

Detailed explanation-1: -Eosinophils are a type of disease-fighting white blood cell. This condition most often indicates a parasitic infection, an allergic reaction or cancer. You can have high levels of eosinophils in your blood (blood eosinophilia) or in tissues at the site of an infection or inflammation (tissue eosinophilia).

Detailed explanation-2: -The most common parasitic infections associated with eosinophilia in refugees are the soil-transmitted helminths (trichuris, ascaris and hookworm), strongyloides, and schistosoma as well as many tissue-invasive parasites (e.g. parasites that migrate through human tissues as a part of their life cycle).

Detailed explanation-3: -Eosinophilia is a central feature of the host response to helminth infection. Larval stages of parasitic worms are killed in vitro by eosinophils in the presence of specific antibodies or complement. These findings established host defense as the paradigm for eosinophil function.
