Infection rates and number of CD11b ⁺ , CD11c ⁺ , or CD3 ⁺ cells infected with N. caninum -expressing GFP

		Infection rates (%)	Infected cell number (×10 4 )
CD11b+ cells	WT	2.03 ± 0.70, P = 0.255	9.68 ± 3.05, P = 0.73
	CCR5−/−	3.08 ± 1.93	9.09 ± 2.65
CD11c+ cells	WT	3.81 ± 1.01, P = 0.534	3.79 ± 1.27, P = 0.19
	CCR5−/−	4.23 ± 1.23	2.85 ± 1.07
CD3+ cells	WT	0.30 ± 0.18, P = 0.131	0.55 ± 0.22, P = 0.45
	CCR5−/−	0.80 ± 0.66	0.67 ± 0.31

Peritoneal cells were obtained from CCR5^−/− and C57BL/6 mice (WT) at 5 days after infection with 1 × 10⁶  N. caninum tachyzoites expressing GFP (N = 6). Cells were then subjected to flow cytometry to determine the infection rate and absolute number of monocytes/macrophages (CD11b⁺), dendritic cells (CD11c⁺) and T cells (CD3⁺) based on GFP⁺ cells. Data were analyzed by a student’s t-test. GFP: green fluorescent protein.
