Special Issue: "Parasitic Infection and Host Immunity": Editorial.

The number of studies on naturally acquired immune-response-induced VIR proteins in field populations from vivax malaria-endemic areas has been limited. The similar I vir i multigene from I P. vivax i has been studied as an important superfamily gene that takes part in the pathogenesis of vivax malaria besides triggering the host immune activation [[13]]. Parasite-host interactions depend on a complex interplay between the metabolism of the parasite, their antigens, and the host immune response system [[1]]. One of the key characteristics of I Schistossoma mansoni i infection is the eosinophilia accompanied by the granuloma formation, resulting from the migration of inflammatory cells to the site of infection during the control of infection [[18]].
