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]
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.
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.

The crystals are usually detected by imaging and/or joint fluid analysis. [citation needed] X-ray of a knee with chondrocalcinosis. Medical imaging, consisting of x-ray, CT, MRI, or ultrasound may detect chondrocalcinosis within the affected joint, indicating a substantial amount of calcium crystal deposition within the cartilage or ligaments.

Kingella kingae is a species of Gram-negative facultative anaerobic β-hemolytic coccobacilli. First isolated in 1960 by Elizabeth O. King, it was not recognized as a significant cause of infection in young children until the 1990s, when culture techniques had improved enough for it to be recognized.
