Abstract
Antigens derived from Trichinella spiralis were used to challenge, in vitro, sensitized jejunum from infected guinea pigs while monitoring ion transport properties of the tissue. Antigen challenge resulted in dose-dependent increases in trans-epithelial electrical potential difference and short circuit current. Both antigen-stimulated electrical alterations and Schultz-Dale contractions were demonstrated in small intestinal tissue after the passive transfer of immune serum containing anti-trichinella homocytotropic antibodies.
