Effects of Proteus vulgaris OX19 on the spleen cells of rabbits were investigated. Control group (n=5) and Proteus treated group (n=5) of New Zealand male rabbits were used in this study. Bacteria were injected to the rabbits in five days periods with increasing dosages for one month. Thin sections were examined by transmission electron microscope (Jeol 100CXII). Ultrastructural changes were defined in spleen tissue cells due to the antigenic stimulation of bacteria. Spleen cells observed in control group were in normal structure and cells were in close contact with each other. However, spleen cells of Proteus treated group displayed structural changes with regard to the control group in electron microscopic examinations. Chemotaxis of macrophages, forming of pseudopodia and presence of phagocytic vacuoles were observed. Lymphocytes, the major cells of spleen revealed mitotic activity. In addition, chromatin condensation in nucleus and dilatations in perinuclear space were significant. Interactions of lymphocytes and macrophages were noteworthy.

UI	MeSH Term	Description	Entries
D008214	Lymphocytes	White blood cells formed in the body's lymphoid tissue. The nucleus is round or ovoid with coarse, irregularly clumped chromatin while the cytoplasm is typically pale blue with azurophilic (if any) granules. Most lymphocytes can be classified as either T or B (with subpopulations of each), or NATURAL KILLER CELLS.	Lymphoid Cells,Cell, Lymphoid,Cells, Lymphoid,Lymphocyte,Lymphoid Cell
D008264	Macrophages	The relatively long-lived phagocytic cell of mammalian tissues that are derived from blood MONOCYTES. Main types are PERITONEAL MACROPHAGES; ALVEOLAR MACROPHAGES; HISTIOCYTES; KUPFFER CELLS of the liver; and OSTEOCLASTS. They may further differentiate within chronic inflammatory lesions to EPITHELIOID CELLS or may fuse to form FOREIGN BODY GIANT CELLS or LANGHANS GIANT CELLS.

D011514	Proteus vulgaris	A species of gram-negative, facultatively anaerobic, rod-shaped bacteria that occurs in soil, fecal matter, and sewage. It is an opportunistic pathogen and causes cystitis and pyelonephritis.
D011817	Rabbits	A burrowing plant-eating mammal with hind limbs that are longer than its fore limbs. It belongs to the family Leporidae of the order Lagomorpha, and in contrast to hares, possesses 22 instead of 24 pairs of chromosomes.
