Abstract

Four groups of female Swiss Webster mice were injected intraperitoneally with similar volumes of normal saline, sonicated Trypanosoma musculi and saline, sonicated trypanosomes and Freund's Complete Adjuvant (FCA) and FCA. When the mice became immune and thus responded negatively to a T. musculi challenge, sera were collected and administered to four other groups of mice to establish passive immunity in these animals.

An established dose of innoculum of Trichinella spiralis larvae (8.1 larvae/gram of body weight) was given to all the mice by gastric gavage. These mice were killed 26 days later and the musculature digested with artificial gastric juice to release the encysted larvae.

The resulting larval mean counts indicated a slightly higher number of recovered larvae in the FCA control group than in the normal controls and the other two test groups. It is speculated that FCA may exert an unknown influence on some mechanism in the host mouse to permit enhancement of the larval development by suppression of the adult worm expulsion or the structural change of the host's intestinal wall due to the larvipository process.

The antibody, ablastin, may here suppress the development of the larvae in animals immunized against trypanosomes. The results in this experimental procedure show that concomitant exposure to both parasites may have a synergistic effect.
