The infection of a joint can occur in different ways, (I) via injection or during joint operation through direct colonization, (II) by direct contact with a neighboring infected site, or (III) by haematogenous or lymphogenous seed of the pathogen. Another classification of bacterial arthritis distinguishes acute, chronic and reactive forms, which differ in their type of joint infection and their triggering bacteria. Reactive arthritis is a postinfectious complication with no need of presence for viable pathogens in the joint. While reactive arthritis often simultaneously affect several joints, the presence of polyarthritic types of non reactive arthritis occur infrequently and then mostly as a result of several bacteriaemic phases.
