title: Emerging parasite zoonoses: the role of host-parasite relationship.
abstract: Human-parasite relationships have played an essential role in the emergence or re-emergence of some parasitic diseases. These interactions are due to numerous causes. Some are linked to humans (immunodeficiencies due to AIDS among other causes, treatments, nosocomial contaminations, genetic predisposition), others concern the parasite (particular genotypes having modified their parasitic specificity). Several of these causes were predominant in the emergence of parasitoses such as cryptosporidiasis, microsporidioses or, to a certain point, pneumocystosis, the transmission of which has become zoonotic or even anthroponotic, inter-human. Re-emergent diseases (toxoplasmosis, leishmaniasis, giardiasis, strongyloidiasis, scabies) had already been described in human pathology, but their frequency or symptomatology have been drastically modified. In this case also, the unbalanced host-parasite relationship is largely responsible but it can not be dissociated from other causes, especially environmental and nutritional.
