Analysis based on measurements from more than 100 granulomata (n = 8-13 mice per group) from Giemsa-stained liver tissue; methodology was as described.28,29 Data are presented as plus or minus standard error of the mean.
nd indicates not determined.
*
Number of single-egg granulomata was scored per 2.25 cm2 of infected liver tissue.
†
Significant differences between BALB/c and ΔdblGATA at given time point.
‡
Five eosinophils were identified in one granuloma of one TgPHIL mouse.
