Abstract:

Repeated treatments of Leishmania mexicana promastigote cultures with α-difluoromethylornithine could not block proliferation when the parasite was grown in a rich medium. Although the irreversible inhibitor of ornithine decarboxylase was able to abolish the enzymatic activity under these conditions, polyamine depletion was only partial probably due to the uptake of these substances from the external medium. Conversely, when Leishmania was cultivated in a defined medium essentially free of polyamines, α-difluoromethylornithine was able to decrease the growth rate and proliferation was arrested after several passages in the presence of the drug. Parasite multiplication could be resumed by addition of exogenous polyamines, and a strict correlation between Leishmania promastigote growth and intracellular levels of spermidine was observed. © 1991 Academic Press, Inc.
