What does the Mycobacterium tuberculosis complex include?

The Mycobacterium tuberculosis that people often talk about actually refers to Mycobacterium tuberculosis. Once Mycobacterium tuberculosis infects the human body, it will cause tuberculosis. This bacterium will invade various organs in the human body and is most likely to infect the lungs, resulting in the most well-known non-geometry. It should be noted that Mycobacterium tuberculosis is not a single type, but includes many types.

In this case, import-related inspections are also required.

Guidance:

A positive tuberculin test does not necessarily mean that you have pulmonary tuberculosis. So don't worry either. You should go for relevant examinations, such as X-rays and sputum tests. Only then can we be sure.

A positive result for this item indicates the presence of Mycobacterium tuberculosis, and it is possible that previous tuberculosis has not been cured. . It is recommended to take anti-tuberculosis drugs such as isoniazid, which have the advantages of strong bactericidal power, can be taken orally, few adverse reactions and low price. Its main function is to inhibit the synthesis of tuberculosis deoxyribonucleic acid (DNA) and hinder the synthesis of bacterial cell wall.

The nucleic acid test for Mycobacterium tuberculosis complex was positive.

Guidance:

Based on the above situation, the test results include Mycobacterium tuberculosis infection, or it may be an extrapulmonary infection. If there is a cough symptom in the lungs, it is pulmonary tuberculosis.

The main characteristic of this genus of bacteria is that the cell wall contains a large amount of lipids, mainly mycolic acids. This is closely related to its staining, growth characteristics, pathogenicity, resistance, etc. It is generally not easy to color, but if it is heated or the dyeing time is prolonged, it can resist bleaching by the strong decolorizing agent hydrochloric acid ethanol, so it is also called acid-fast bacilli. This genus of bacteria has no flagella, no spores, and does not produce endotoxins or exotoxins. Its pathogenicity is related to the composition of the bacteria. The diseases caused are all chronic and accompanied by granulomas.

Mycobacterium tuberculosis (M. tuberculosis), commonly known as tuberculosis bacillus or tuberculosis bacteria, is the pathogen that causes tuberculosis. It can invade various organs throughout the body, but pulmonary tuberculosis is the most common (because it loves oxygen). Tuberculosis remains an important infectious disease. An estimated one-third of the world's population is infected with Mycobacterium tuberculosis. According to the WHO, approximately 8 million new cases occur each year and at least 3 million people die from the disease. Before the founding of the People's Republic of China, the mortality rate was 200-300 people per 100,000, ranking first among the causes of death from various diseases. After the founding of the People's Republic of China, people's living standards improved, and sanitary conditions improved. In particular, group prevention and treatment were carried out, and children were generally vaccinated with BCG, which greatly reduced the incidence and mortality of tuberculosis. However, it should be noted that in some parts of the world, the incidence rate is on the rise again due to AIDS, drug abuse, the use of immunosuppressants, alcoholism and poverty.
