Others – Fungal and mycobacterial infections are rare causes of septic arthritis and usually have a slow onset of joint symptoms. Mycobacterial joint infection most commonly affects hip and knee joints, caused by reactivation of past mycobacterial infections, with or without signs and symptoms of tuberculosis in lungs.
[6]: p. 360 Septic prepatellar bursitis may be diagnosed if the fluid is found to have a neutrophil count above 1500 per microliter, [5]: p. 608 a threshold significantly lower than that of septic arthritis (50,000 cells per microliter). [6]: p. 360 A tuberculosis infection can be confirmed using a radiograph of the knee and urinalysis. [12]
Septic arthritis is an inflammatory response to an infection (usually bacterial) in the joint. Usually impacting large joints like the hip or the knee, it is a medical emergency with a mortality rate of about 10%. It is treated with oral and intravenous antibiotics as well as joint drainage. [2]
Other causes include systemic diseases such as tubercular arthritis (a form of arthritis that developed due to being infected by tuberculosis), septic arthritis, and non-infective inflammatory arthritis. When a patient contracts a disease such as tuberculosis or a bacterial infection, it causes damage to the blood vessels.
Septic arthritis is the purulent invasion of a joint by an infectious agent [5] [6] with a resultant large effusion due to inflammation. [7] Septic arthritis is a serious condition. It can lead to irreversible joint damage in the event of delayed diagnosis or mismanagement. It is basically a disease of children and adolescence. [6]
Causes: microorganisms (usually bacteria, but also fungi) causing infection of a prosthetic joint: Risk factors: smoking, diabetes, immunosuppression, obesity, chronic liver or kidney disease: Diagnostic method: Based on culture of microorganism from the affected joint, or other indirect methods such as inflammatory cells detected in joint aspirate

Fungal sepsis accounts for approximately 5% of severe sepsis and septic shock cases; the most common cause of fungal sepsis is an infection by Candida species of yeast, [29] a frequent hospital-acquired infection. The most common causes for parasitic sepsis are Plasmodium (which leads to malaria), Schistosoma and Echinococcus.
