TABLE 1.

Antimony susceptibility of L. infantum before and after experimental infections of P. perniciosus^a

^aThe susceptibility of promastigotes to SbIII before [Pro(In)] and after [Pro(Pern)] development in P. perniciosus and susceptibility of intramacrophagic amastigotes to SbV before P. perniciosus infection [Ama(In)] and amastigotes derived from promastigotes after P. perniciosus infection [Ama(Pern)]. Results are mean values from three independent experiments. Shading indicates results obtained in experiments with the three Sb-resistant L. infantum strains. ND, not determined.
