Mycobacterium chelae infection

Introduction to Mycobacterium tuberculosis infection The disease caused by Mycodacteriumcheloneiinfection is similar to Mycobacterium fortuitum, so it is often called the occasional turtle complex Mycobacterium. The pathogenesis is still unclear. Mainly cause lung and skin wound infection, cultured on 37 ° C medium for 2 to 5 days to grow smooth or rough colonies, and can produce aromatic sulfatase, nitrate reduction test and iron absorption test negative, can be diagnosed. It is sensitive to erythromycin, cephalosporins, tetracyclines and the like. basic knowledge The proportion of sickness: 0.003%-0.005% Susceptible people: no specific population Mode of infection: non-infectious Complications: pneumonia

Mycobacterium tuberculosis infection cause

(1) Causes of the disease

The disease caused by mycodacterium chelonei infection is similar to that of mycobacteria, so it is often called the occasional turtle complex mycobacteria, both of which can be cultured on a medium of 37 ° C for 2 to 5 days to grow smooth or rough. Type colonies, and can produce aromatic sulfatase, nitrate reduction test and iron absorption test negative.

(two) pathogenesis

The pathogenesis is still unclear, and there is currently no relevant content description.

Mycobacterium tuberculosis infection prevention

The disease caused by Mycodacterium chelonei infection is similar to Mycobacterium fortuitum, so it is often called the occasional turtle complex Mycobacterium. The disease is mainly transmitted through the respiratory tract and contact, so the preventive measures should be carried out according to the cause. During the epidemic, masks and gloves should be worn to reduce the possibility of contact between the respiratory tract and the skin. If there are suspicious contacts, oral erythromycin can be prevented.

Mycobacterium tuberculosis infection complications Complications pneumonia

Usually complicated by pneumonia.

Mycobacterium tuberculosis infection symptoms common symptoms wound infection toxemia

Mycobacterium tuberculosis infection mainly causes infection of the lungs and skin wounds. For severe cases, sepsis can be caused by infection entering the blood circulation. Clinical manifestations mainly cause lung and skin wound infections. Smooth or coarse colonies were grown on culture medium at 37 ° C for 2 to 5 days, and aromatic sulfatase was produced, and the nitrate reduction test and the iron absorption test were negative. You can diagnose.

Examination of Mycobacterium tuberculosis infection

Smooth or coarse colonies were grown on culture medium at 37 ° C for 2 to 5 days, and aromatic sulfatase was produced, and the nitrate reduction test and the iron absorption test were negative.

Diagnosis and identification of Mycobacterium tuberculosis infection

Differential diagnosis:

1. Bacterial pneumonia: In the acute phase of tuberculous pleurisy, there is often fever, chest pain, cough, shortness of breath, leukocytosis, chest X-ray showing high-density uniform shadow, easily misdiagnosed as pneumonia. However, when coughing, there are many coughs, often rust-colored. The lungs are solid signs, and pathogenic bacteria can often be found in sputum smear or culture. Tuberculous pleurisy is mainly dry cough, the chest is a fluid sign, and the PPD test can be positive.

2. Pneumonal pleural effusion: occurred in bacterial pneumonia, lung abscess and bronchiectasis with pleural effusion, patients with a history of lung lesions, the amount of fluid is not much, found in the ipsilateral side of the lesion. The number of white blood cells in pleural fluid increased significantly, mainly neutrophils, and pleural fluid culture may have pathogenic bacteria growth.

3. Malignant pleural effusion: Pulmonary malignant tumor, breast cancer, lymphoma, direct invasion or metastasis of pleura, pleural mesothelioma, etc. can produce pleural effusion, and pulmonary tumor with pleural effusion is the most common. Identification of tuberculous pleural effusion and neoplastic pleural effusion. Tuberculous pleurisy sometimes needs to be differentiated from patients with systemic lupus erythematosus pleurisy, rheumatoid pleurisy and other pleural effusions. These diseases have their own clinical characteristics, and identification is not difficult.
