Chromobacteriosis

Introduction to colorectal disease Chromobacteria is caused by a class of non-spore-forming gram-negative bacilli, staining bacilli. The pathogens are found in water and soil, and are also present in the blood in contaminated blood banks. There is often a clear history of exposure, and a number of people have a disease. The number of rashes is large and occurs in the trunk. In severe cases, the skin is found to have a fluctuating abscess or localized cellulitis with lymphatic and lymphadenitis. In severe cases, it can cause fatal sepsis. The diagnosis is mainly based on bacteriological examination, tetracycline, chloramphenicol, streptomycin. And so on. basic knowledge The proportion of illness: 0.03% Susceptible people: no specific population Mode of infection: non-infectious Complications: sepsis

Cause of colorectal disease

(1) Causes of the disease

Chromobacteria is caused by a bacterium, which is a kind of gram-negative bacillus that does not produce spores. It produces various pigments on gelatin broth medium, in which melanin-producing melanin is produced and produced. The purple staining bacterium of the dyeing pigment is most common.

(two) pathogenesis

The pathogenesis is still not very clear. It may be that after exposure to contaminated blood, water, soil, etc., it is invaded into the skin by the staining bacterium, and it grows and multiplies into the blood, causing rash or sepsis.

Colorectal disease prevention

The diet should be regular and reasonable, that is, high-protein, high-vitamin foods.

Bacterial plague complications Complications sepsis

With lymphatic and lymphadenitis, severe cases can cause lethal sepsis.

Symptoms of colorillosis Common symptoms Cellulitis

Generally no symptoms, often have a clear history of exposure, a moderate number of people with symptoms, mild symptoms are superficial ulcers on the skin from large needles to mung beans, with black suede attached; a large number of purple or black powder in the center The substance is attached, there is a narrow blush around, the number of rashes is numerous, and it occurs in the trunk. If the symptoms are severe, the skin may have a fluctuating abscess or localized cellulitis, accompanied by lymphatic vessels and lymphadenitis. Lethal sepsis.

The diagnosis is mainly based on bacteriological examination, and the pus in the skin lesion can be taken, and cultured in a gelatin broth medium in an incubator at 35 to 37 ° C, and the staining bacillus is found to be diagnosed.

Examination of staining bacillosis

Bacteriology examination, taking the pus at the skin lesion, cultured in a gelatin broth medium in an incubator at 35-37 ° C, and found a staining bacterium.

Diagnosis and identification of colorectal disease

Generally no symptoms. There is often a clear history of exposure, and a middle-aged person is ill. The mild symptoms are superficial ulcers with large needles and large mung beans on the skin, which are covered with black suede; there are a lot of purple or black powdery substances attached to the center, and there are narrow blush around, and the number of rashes is large. trunk. In severe cases, the skin is found to have a fluctuating abscess or localized cellulitis with lymphatic and lymphadenitis, and severe cases can cause fatal sepsis. The diagnosis is mainly based on bacteriological examination, and the pus in the skin lesion can be taken, and cultured in a gelatin broth medium in an incubator at 35 to 37 °C. The staining bacillus is found and can be diagnosed.
