| Abstrakt: |
Tissue homogenates containing amastigotes of either Leishmania donovani, L. tropica, or Trypanosoma cruzi were rapidly frozen with 10% glycerol as cryoprotectant. Viability and pathogenicity were maintained for at least 23 years with the Khartoum strain of L. donovani, 22 years with the Malakal strain of L. donovani, and 7 years for L. tropica and T. cruzi. Similar results over a shorter period of time were obtained with a slow-freezing technique. |
