Resumo em Inglês
In vitro assays play an important role in the discovery and development of new antileishmanial drugs. The classic macrophage-amastigote models using murine peritoneal macrophages or human-monocyte derived macrophages as host cells are useful for drug screening. A major limitation of these models is the dependence on microscopic counting, a time-consuming and subjective method of analysis. The present study describes a detailed protocol for applying quantitative real-time PCR (qPCR) as an accurate and sensitive tool to assess parasite load in an amastigote-macrophage model. This assay can be performed in a standardized medium-to-high throughput procedure, replacing traditional readout of number of amastigote per macrophages by DNA load measurement.
