Use of 111In-labelling to follow tissue distribution of Candida albicans in mice.

Two strains of Candida albicans, a wild type and a derived mutant, were labelled with 111Inoxine. Labelled cells were injected into mice and tissue distribution patterns were determined from 0.5 to 48 h. During the first 4-h post-injection phase, remarkable differences in tissue distribution were observed between the two strains. Radiolabelling of C. albicans with 111Inoxine is shown to be a much more reliable method for determining early tissue distribution patterns in infected animal models than culturing the infected tissue.
