Bordeaux, August 17, 1994. Dear colleagues, I am trying to grow amastigote forms of Leishmania infantum, but without success. They look like they remain alive but they do not multiply. Would anyone be able to give me some hints about tis problem ? Thanks in advance, sincerely, Gilles Merlin E-Mail Address: merlin at frbdx11.cribx1.u-bordeaux.fr
