Induction of a marked eosinophilia by cyclophosphamide in Toxocara canis infected SJL mice.

abstract：:Entamoeba histolytica is the aetiological agent of invasive amoebiasis, the third leading parasitic cause of mortality in the world. The disease can be easily cured by chemotherapy; however, prevention, mainly in the form of vaccination, could greatly decrease the incidence of the disease, and possibly help in its era...
