Tissue reaction of the liver of cattle to an artificial or natural infection with Cysticercus bovis.

An evaluation of the tissue reaction to Cysticercus bovis in the liver of calves with an artificial infection and that of oxen with a natural infection provided evidence for the fact that the liver of these animals responded to an infection with C. bovis with an extensive granulomatous reaction. A comparison of tissue reaction to cysticerci at an identical stage of development showed that the reaction of the liver parenchyma was much more intensive than that of the heart and the skeletal muscles. In the described cases, this intensive reaction caused the death of the cysticerci before the completion of their development. Evidence was obtained for the first time that also in the liver C. bovis was located in the lymphatic vessels.
