abstract：:Candida species are increasingly important fungal pathogens. The reaction of rat alveolar macrophages (AM) to Candida albicans was compared with that to C. glabrata and C. krusei. Phagocytosis of C. glabrata was similar to that of C. albicans, but significantly slower for C. krusei due to reduced attachment. After ops...
