Functional and ultrastructural changes in alveolar macrophages from rabbits colonized with Bordetella bronchiseptica.
Alveolar macrophages from rabbits colonized with Bordetella bronchiseptica in their respiratory tract exhibited significant decreases in cell adherence, phagocytic uptake, and bactericidal activity compared with macrophages from uncolonized animals. These dysfunctions were accompanied by ultrastructural changes, including a decrease in overall cell density, a vacuolation of the rough endoplasmic reticulum, and an increase in organelle-poor cell surface projections.
