Erysipelas

Introduction to erysipelas The disease is caused by the infection of E. erythropolis, and the most clinically manifested is the erysipelas-like type, which is an acute but slow-moving skin disease. E. erythropolis (formerly known as insidious erysipelas) is a Gram-positive, non-capsulated, non-forming spore, inactive micro-aerobacteria distributed throughout the world, which is mainly saprophytic. Erythromycin erythropolis (formerly known as insidious erysipelas) is a Gram-positive, non-capsulated, non-forming spore, inactive micro-aerobacter, distributed throughout the world, it is mainly saprophytic, however It infects a variety of living animals including insects, shellfish, fish, birds and mammals (especially pigs). Human infections are mainly occupational, typically by hand-operating edible or inedible animals [infected animal carcasses, extracted products (grease, fertilizer), bone, shell] when stabbed and infected, non-skin infections Rare, usually with arthritis and endocarditis. basic knowledge The proportion of illness: 0.005% - 0.008% Susceptible people: no specific population Mode of infection: contact spread Complications: bacteremia

Causes of erysipelas

Cause:

Erythromycin erythropolis (formerly known as insidious erysipelas) is a Gram-positive, non-capsulated, non-forming spore, inactive micro-aerobacter, distributed throughout the world, it is mainly saprophytic, however It infects a variety of living animals including insects, shellfish, fish, birds and mammals (especially pigs). Human infections are mainly occupational, typically by hand-operating edible or inedible animals [infected animal carcasses, extracted products (grease, fertilizer), bone, shell] when stabbed and infected, non-skin infections Rare, usually with arthritis and endocarditis.

Arsenic bacillus prevention

Anyone who has access to meat, fish and other food contaminated with erysipelas, such as slaughterers, meat processing workers, herders, fishermen, fish processing workers, cooks, food handlers, etc., may be infected as long as the fish And meat continues to be an important economic commodity, erysipelas infection will be a significant occupational hazard, so personal protection of the above personnel is the key to prevent this disease.

Complications of erysipelas plague Complications bacteremia

1. erysipelas arthritis: after joint infection with erysipelas erythematosus, the main manifestations of redness, pain, and limited mobility of the joints. CT examination can see the full fluid in the joint cavity. The treatment is mainly anti-infection. 25% magnesium sulfate hot compress symptomatic treatment.

2. erysipelas endocarditis: after bacterial infection can be infected with endocarditis with blood circulation, can have high fever, palpitations, chest tightness, cardiac auscultation can be heard and murmur, echocardiography combined with blood culture examination can confirm the diagnosis .

Biopsy thick skin culture and isolation of E. erythropolis is superior to acupuncture suction culture at the edge of lesion expansion, and the exudate obtained from the wear of reddish papules has diagnostic value. For the diagnosis of erysipelas arthritis or endocarditis, it is necessary to isolate bacteria from blood or synovial fluid. PCR amplification of the DNA sequence of E. erythraea encoding 16srRNA is helpful for rapid diagnosis.

Examination of erysipelas

Biopsy thick skin culture and isolation of E. erysii is better than acupuncture suction at the edge of lesion expansion. The exudate obtained from the wear of reddish papules also has diagnostic value. For the diagnosis of erysipelas arthritis or endocarditis, bacteria must be isolated from blood or synovial fluid. PCR amplification assays for the DNA sequence of E. erythraea encoding 16srRNA facilitate rapid diagnosis.

Diagnosis and identification of erysipelas

1, contact dermatitis has a history of contact, itching and no tenderness, no systemic symptoms.

2, cellulitis, redness and swelling of the realm is unclear, deep infiltration, obvious purulent.

3, angioedema occurs in the loose parts of the tissue, the damage is edematous, the edges are unclear, no tenderness.
