- dpi: days post infection when abortion occurred.
-
aThe G1 group was divided due to the differences found (histology, detection and burdens), depending on whether the animals aborted during the second or third wpi.
-
bHistopathological lesion severity: none detected (–), consistent with (+), and characteristic of (++) N. caninum infection.
-
cFractions represent the number of positive animals/total number of animals assessed by nested-ITS1 PCR, and figures within brackets represent the median values of parasite burden (tachyzoites/mg tissue).
