The sow had a high titer for Leptospira spp. Some or all of the fetuses may have been infected and died due to a leptospiral septicemia. Mummification had started in some fetuses.
Two 24 to 26 day embryos from the uterus with a damaged feto-placental unit. Cause not determined. There is evidence of hemorrhage in the chorionic vessels of the upper embryo.
