Only rarely an infectious arthritis is caused in this localization by viruses or fungi. Native joint infections of the hip are less common than infections after implantation of prosthetic devices. Difficulties in prosthetic joint infections are I a higher age of patients and thus an associated presence of other medical risk factors II often long courses of treatment regimes depending on the bacterium and its antibiotic resistance III an increased mortality and IV a high economic burden for removal and reimplantation of an infected prosthetic device. The pathogenic mechanisms responsible for articular infections are well studied only for some bacteria . Staphylococcus aureus while others are only partially understood. Important known bacterial properties and microbiological characteristics of infection are the bacterial adhesion on the native joint or prosthetic material the bacterial biofilm formation the development of small colony variants SCV as sessile bacterial types and the increasing resistance to antibiotics. Key words arthritis bacteria diagnosis prosthesis therapy Infectious arthritis 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 .
