抄録

Currently used macrophage-mycobacterial in vitro infection models require substantial numbers of macrophages. We developed a miniaturized version of such a model, using microtiter plates, which is comparable to standardly published methods, is reproducible, and requires fewer macrophages. In addition to its ease of handling and its economy in time, number of animals, and supplies, this method is preferable when limited numbers of macrophages are available. We have used this assay as a means of selecting human derived isolates from patients with M. avium intracellulare pulmonary disease for their ability to infect and multiply in cultured mouse pulmonary alveolar macrophages.
