To understand the extent of the invasion and inflammation in C. albicans-colonized Rag2γc and B6 mice under the influence of antibiotics, stomach tissues collected 14 days after infection were stained with PAS and an antibody specific for CD11b, which is expressed on the surface of inflammatory cells, such as macrophages, dendritic cells, NK cells and neutrophils. The gene discussed is ITGAM; the disease is infection.
