Transport of serum IgA into bile of sheep infected with Fasciola hepatica.
Sheep infected with Fasciola hepatica were studied for their ability to transport intravenously injected radiolabelled IgA from serum to bile. The results show that there was an apparent reduction in the selectivity of transport of IgA into bile in infected animals compared with uninfected controls. However, in infected animals the biliary flow rate was approximately twice that of uninfected animals, and the total amount of radiolabelled IgA transported was similar irrespective of infection status. The possible relevance of the elevated biliary flow rate is discussed with respect to the pharmacokinetics of drugs used for the chemotherapy of helminth infections in sheep.
