Most cases of septic arthritis involve only one organism; however, polymicrobial infections can occur, especially after large open injuries to the joint. [15] Septic arthritis is usually caused by bacteria, but may be caused by viral, [16] mycobacterial, and fungal pathogens as well. It can be broadly classified into three groups: non ...
Horses may acquire cellulitis, usually secondarily to a wound (which can be extremely small and superficial) or to a deep-tissue infection, such as an abscess or infected bone, tendon sheath or joint. [33] [34] Cellulitis from a superficial wound usually creates less lameness (grade 1–2 of 5) than that caused by septic arthritis (grade 4–5 ...
Most septic arthritis cases caused by anaerobic bacteria are monomicrobial. The predominant anaerobic bacteria isolated are Peptostreptococcus spp. and Propionibacterium acnes (frequently found in prosthetic joint infection), B. fragilis and Fusobacterium spp. (frequently found in infections of hematogenic origin), and Clostridium spp ...
Inflammatory arthritis can sometimes cause symptoms in parts of the body other than the joints, like the eyes, heart, or lungs. As arthritis progresses, joint damage can get worse.
impetigo, cellulitis, and erysipelas – infections of the skin which can be complicated by necrotizing fasciitis – skin, fascia and muscle; strep throat AKA strep pharyngitis – pharynx; Less common: bacteremia can be associated with these infections, but is not typical. septic arthritis – joints; osteomyelitis – bones
Cellulitis can be caused by normal skin flora or by contagious contact, and usually occurs through open skin, cuts, blisters, cracks in the skin, insect bites, animal bites, burns, surgical wounds, intravenous drug injection, or sites of intravenous catheter insertion. In most cases it is the skin on the face or lower legs that is affected ...
The area may be red , warm to the touch, or surrounded by cellulitis, particularly if infection is present, often accompanied by fever. [5]: p. 608 Unlike arthritis, except in severe cases prepatellar bursitis generally does not affect the range of motion of the knee, though it may cause some discomfort in complete flexion of the joint.
It is also possible to have a local skin and soft tissue infection, known as cellulitis, in the structures that overly the elbow resulting in pain. [6] When the infection affects deeper structures the joint or bursa, then a more serious diagnosis of bursitis or septic arthritis is made. [7]
