Parasite burden is increased in lupus-prone mice.

<p>Mice were sacrificed 7–10 days following infection and peritoneal lavage was performed. A cytospin was prepared from each mouse and then the percent of infected cells was quantified. (A) B6.<i>lpr</i> mice showed a significant increase in parasite burden 9 dpi. (B) BXSB mice had significantly increased parasite burden 7 dpi. Each experiment was carried out 2–3 times with 3–6 mice per group.
