Skin manifestations of DF-2 sepsis

Introduction to skin manifestations of DF-2 sepsis The skin manifestations of DF-2 sepsis (Cutaneous Manifestations of DF-2 Septicemia) were first reported by Bobo et al in 1976, and the pathogen DF-2 (dystonicfermenter type 2) was a Gram-negative bacillus. The pathogen DF-2 is often parasitic in the oropharynx of healthy dogs. The infection usually occurs in people who are bitten by dogs or in contact with dogs, especially those with impaired immune function. Therefore, this disease is an animal disease that can be transmitted to humans. The pathogenesis is still not clear. After being bitten by a dog, fever, nausea, vomiting, and disseminated intravascular coagulation suddenly occur within 1 to 3 days. The diagnosis is mainly based on blood or cerebrospinal fluid, and it is found that the gram-negative bacilli are illegible. Antibiotics are sensitive. basic knowledge The proportion of illness: 0.001% Susceptible people: no specific people Mode of infection: non-infectious Complications: diffuse intravascular coagulation meningitis cellulitis

Skin manifestations of DF-2 sepsis

(1) Causes of the disease

The skin manifestations of DF-2 septicaemia (Cutaneous Manifestations of DF-2 Septicemia) were first reported by Bobo et al in 1976, and its pathogen DF-2 (dystonic fermenter type 2) is a Gram-negative bacillus, oxidase and hydrogen peroxide. The enzyme is positive and can restore nitrate.

(two) pathogenesis

The pathogenesis is still inaccurate. After being bitten by a dog, the pathogen DF-2 invades the human body, rapidly growing and breeding, causing fever, diffuse intravascular coagulation and other symptoms.

Skin performance prevention of DF-2 sepsis

The disease was first reported by Bobo et al in 1976. Its pathogen DF-2 is a Gram-negative bacilli, positive for oxidase and catalase, which can reduce nitrate. This bacterium is often parasitic in the oropharynx of healthy dogs. The infection usually occurs in people who are bitten by dogs or who are in contact with dogs. In particular, people with impaired immune function, such as splenectomy and alcoholism, are susceptible to infection. Therefore, this disease is an animal disease that can be transmitted to humans.

Skin manifestations of DF-2 sepsis Complications, diffuse intravascular coagulopathy, cellulitis

Diffuse intravascular coagulation, meningitis, endocarditis, cellulitis, bacteremia may occur.

Symptoms of skin manifestations of DF-2 sepsis Common symptoms Porphyria nausea meningitis sepsis intravascular coagulopathy

Frequent fever, nausea, vomiting, diffuse intravascular coagulation, etc. may occur within 1 to 3 days after being bitten by a dog. Meningitis, endocarditis, cellulitis, bacteremia, arthritis and rash may occur. Skin damage causes necrotic irritations in the bitten area, and other areas may develop macules, maculopapular rash, urticaria and sputum.

Examination of skin manifestations of DF-2 sepsis

The blood or cerebrospinal fluid was cultured and found to be illegible for the elongated Gram-negative bacilli.

Diagnosis and differentiation of skin manifestations of DF-2 sepsis

The diagnosis mainly relies on blood or cerebrospinal fluid culture, and it is found that the illegible slender Gram-negative bacilli are confirmed to be DF-2 according to morphological and biochemical reactions. Westerink is equivalent to the laboratory test of the disease in 1987. The only latex characterized by Cerebrospinal Fluid Cryptococcus antigen is The agglutination test was false positive.
