Relationship between presence of placental and placental histopathology changes depending on the species of Plasmodium Colombia^*

Characteristic	Species by microscopy		P(M-W)
	Plasmodium vivax (n = 15)	P. falciparum (n = 2)
Mean no. parasites	1.1 ± 1.6	67 ± 90.5	0.052
Total hemozoin score (median)	0.40 ± 0.51	2.0 ± 1.41	0.043
Mean no. mononuclear cells	12.47 ± 10.64	21.00 ± 9.90	0.133
Mean no. PMNs	13.20 ± 5.65	3.50 ± 2.12	0.044
Mean no. fibrinoid deposits	15.20 ± 6.60	39.50 ± 34.65	0.295

^*Values are mean ± SD scores. PMNs = polymorphonuclear neutrophils.
