The effect of parasite infections on amino acid (AA) flux across the hind limbs in lambs infected with or without Trichostrongylus colubriformis and fed fresh lucerne (Medicago sativa), was investigated using an arterio-venous preparation. The lambs were infected with 6000 T. colubriformis L3 larvae per day for 6 days (n=5) or kept as parasite-free controls (n=5). On day 48 of the experiment, t...

BACKGROUND Oral infection of C57BL/6J mice with the protozoan parasite Toxoplasma gondii leads to a lethal inflammatory ileitis. PRINCIPAL FINDINGS Mice lacking the purinergic receptor P2X7R are acutely susceptible to toxoplasmic ileitis, losing significantly more weight than C57BL/6J mice and exhibiting much greater intestinal inflammatory pathology in response to infection with only 10 cyst...
