Possible outcomes of the introduction of the CI+MK double infection

	C1 > 1?	C2 > 1?	C3 > 1?	Further conditions	Result (stable equilibria)
I	No	No	No		U
II	No	No	Yes		MK, U
III	Yes	No	Yes	CI and MK parameters higha	CI+MK, CI, MK, Ub
				Else	MK, U
IV	No	Yes	No		CI, U
V	Yes	Yes	No		CI, U
VI	Yes	Yes	Yes		CI+MK, CI, MK, Ub

^aHere, CI parameters are F _CI, l _CI, and t _CI, and MK parameters are F _MK, t _MK, and β

^bFor most of the parameter range, CI+MK and CI dominate over MK and U (see main text)
