Labeled leukocytes accumulate in the reticuloendothelial cells, or fixed macrophages of the bone marrow, the normal distribution of which closely parallels that of the hematopoietically active marrow, which is limited to the axial skeleton and proximal humeri and femurs in normal adults.
Rickettsia are gram-negative, obligate intracellular bacteria that are able to invade various eukaryotic host cells such as reticuloendothelial cells and vascular endothelial cells in vertebrates, and epithelial cells in their invertebrate arthropod vectors.

Furthermore, ferric salts promote the formation and deposition of intra-articular CPPD crystals by inhibiting the activity of synovial pyrophosphatase (manifested as chondrocalcinosis on radiographs) and by decreasing the clearance of intra-articular immune complexes by inhibiting the activity of synovial reticuloendothelial cells.
The amastigote forms continue to multiply within mononuclear phagocytes, Kupffer cells, and reticuloendothelial cells in the spleen and lymphoid tissues until they (1) are successfully killed by the immune system (conferring immunity), (2) overwhelm host immunity at a local site causing an active infection, or (3) metastasize to the viscera, mucosa, or skin.
