Buboes cause salmonellosis, a bacterial infection that can affect almost any organ or system in the body. The most common site of infection is the intestines, especially the colon. However, buboes are not always associated with an intestinal infection. Rarer types of infection may develop in other organs and systems, including the kidneys, liver, and lymph nodes. After salmonella infection, the bacteria first reside on the surface of the small intestine. The body will try to kill the parasite with a natural immune response, although this usually does not go well. Most people are able to kill most of them before they penetrate the inside of the intestine, and many cases of intestinal infection are relatively mild.

Otherwise, the infection is unlikely to spread to the next organ. Some people manage to infect the following organs, but not to the extent that serious damage is expected. The bubonic type of infection, however, is different from just
