Body weight:
Slight reduction in the mean body weight gain was noted in females on Day 14 postexposure.
Gross pathology:
The following gross pathology was noted at the terminal sacrifice: one male had dilated, fluid filled left renal pelvis; one male and one female had enlarged mandibular lymph nodes; another female had dilated right renal pelvis containing firm, granular, white material and uterine horns distended with clear fluid; and one female had a dilated right renal pelvis containing white granular fluid. Three of five males and two of five females had no observable abnormal lesions at the terminal sacrifice.
