Abstract

Facultative parasitic infections recently have an obvious effect on human morbidity and mortality, especially in immunosuppressed patients. Change of life cycle stages of facultative parasites between a free-living life and parasitic life according to environmental conditions is one of its most important features. Prevention of these parasites is done by increasing the level of medical knowledge of the people about facultative parasites, knowing habitat in which these parasites spent their free living stages and necessity of hand washing, safe disposal human feces and water sanitation. The aim of this review is to precisely discuss most of these parasites (helminths including Strongyloides species, protozoa including free living ameba and arthropods including flies larva triggering facultative myiasis as an example of each class) together with associated medical conditions
