Summary of cue treatment groups, sample sizes, rationales, and classifications

Cue treatment	N	Rationale	Classification
			Treatment	Lysed parasites	Lysed RBC
Control	5	No-treatment control for the stress of handling and injections	C	NP	NL
Uninfected RBC	5	Control for the stress of handling and injecting the host with blood	U	NP	NL
Uninfected lysed RBC	10	To test for a response to RBC debris	UL	NP	L
AJ-infected lysed RBC	10	Compare AJ to UL to test for a response to high density of self	AJ	P	L
ER-infected lysed RBC	10	Compare ER to AJ to test for a response to non-self	ER	P	L

The analysis involved comparing individual cue treatments and comparing treatments grouped in different ways to test whether parasites respond to lysed parasite material (P vs NP) and/or to lysed RBC material (L vs NL) . N = number of mice that received a particular treatment.
