Streptococcal joint infection

Streptococcal joint infection, also known as streptococcal septic arthritis, is an acute bacterial infection of the synovial joint space caused by species of the genus *Streptococcus*, such as *Streptococcus pyogenes* (Group A), *Streptococcus agalactiae* (Group B), or *Streptococcus pneumoniae* Pathophysiologically, the bacteria seed the highly vascular synovium via hematogenous dissemination or direct inoculation, triggering a pronounced host inflammatory response, neutrophilic infiltration, a...

Pathophysiologically, the bacteria seed the highly vascular synovium via hematogenous dissemination or direct inoculation, triggering a pronounced host inflammatory response, neutrophilic infiltration, and purulent effusion that can rapidly lead to articular cartilage erosion, subchondral bone destruction, and permanent joint dysfunction
