Answer

Polymicrobial joint infections (5-10% of cases) and infection with anaerobic organisms (5% of cases) are usually a consequence of trauma or abdominal infection. The organism of Lyme disease (ie, Borrelia burgdorferi), a large variety of viruses (eg, human immunodeficiency virus [HIV], lymphocytic choriomeningitis virus, hepatitis B virus, rubella virus), mycobacteria, fungi (eg, Histoplasma species, Sporothrix schenckii, Coccidioides immitis, Blastomyces species), and other pathogens may produce nonsuppurative joint infection.
