“…Similar results were observed with antibodies against Leishmania spp. (Doyle, Behin, Mauel & Rowe 1984), T. cruzi (Abelha, Azevedo & Teixeira 1981), T. lewisi (Cherian & Dusanic 1978) and E. histolytica (Aust‐Kettis & Sundqvist 1980). Russo, Grab, Lonsdale‐Eccles, Shaw & Williams (1994) further showed that monoclonal antibodies were also internalized in T. brucei even in the absence of antigen–MAb‐001 complex.…”
