Background mouse	Plasmodium strain	Helminth type	Coinfection time*	Malaria disease outcome	Ref.
BALB/c	P. yoelii 17 NXL	E. caproni	3 wks	Ec showed counterregulatory antiparasite cytokine responses to non-lethal strain PyNXL (less IFN-γ and high IL-4 levels induced by Ec)	[148]
BALB/c	P. yoelii 17 NXL	E. caproni	5 wks	Increased mortality and pathology; the pathology was reversible through clearance of Ec by praziquantel treatment	[151]
BALB/c	P. yoelii 17XL	E. caproni	5 wks	Ec does not alter the course of Py17XL infection	[151]
