Contribution to the pathology of strobilocercosis (Strobilocercus fasciolaris) in the liver of man and some animals.

Tissue reactions with liver strobilocercosis were studied in man, pheasant and muskrat on the basis of histological examination. Microscopical changes in the liver induced by completely developed and still quite vital strobilocerci are very similar in all these hosts and in all cysts the parasite was enveloped by a fibrous capsule consisting of two layers. The development of regressive changes and the character of tissue reaction during the death of the parasite are discussed. Strobilocercus fasciolaris was found for the first time in man, in a solitary cyst in the liver. The possibility of massive infestation of man liver is pointed out.
