Clinical Microbiology Is The Basis Of Clinical Medicine
Jun 22, 2017

Clinical microbiological work using this powerful manual and automated technology as well as a comprehensive culture and clinical diagnostic product line to achieve rapid and accurate infection diagnosis, providing better patient care.

Clinical microbiology is a science that studies the morphology, structure, classification and life of microbes, including bacteriology, virology, and mycology. Clinical Microbiology Is one of the foundations of clinical medicine to guide the diagnosis, treatment and prevention of infectious diseases.

Clinical microbiology is a bridge between the foundation and the clinical discipline.

The significance of clinical microbiology

From the relationship between microbes and common diseases, frequently occurring

1. Tuberculosis, viral hepatitis, dental caries and periodontal disease, Clinical Microbiology sexually transmitted diseases, etc. are caused by pathogenic microorganisms

(1) tuberculosis

1/3 population (about 2 billion) infected with tuberculosis, if not take measures, nearly 10 years there are 300 million people infected;

Tuberculosis patients 20 million

95% in developing countries

800 to 10 million new cases each year, 75% of the age of 15 to 50 years old

Every day died of tuberculosis 8000 people, 3 million per year, 98% in developing countries

Infection rate was 44.5% (2000 survey), infected by 550 million

Existing tuberculosis patients (active) 4.5 million people

Died of tuberculosis each year 12.7 million people, died in rural areas 9th, Clinical Microbiology single disease first. Of which 21.6% had never received treatment.

(2) viral hepatitis

There are a variety of to B, hepatitis C the greatest harm. Only hepatitis B infection rate of 10% or more, that is, more than 100 million HBsAg carriers, Clinical Microbiology chronic hepatitis B patients more than 30 million.

(3) dental caries and periodontal disease

WHO is classified as the only three major focus on cardiovascular disease and cancer prevention and treatment of non-communicable diseases

Caries caused by Streptococcus mutans, periodontal disease caused by anaerobic bacteria

The prevalence of dental caries in our country was 13.9%

(4) STDs

AIDS: the global total of 36.1 million patients by the end of 2000, Clinical Microbiology the number of deaths reached 21.8 million, 95% in developing countries.

China's first half of 2002, the total number of infected has reached 100 million, if not take effective measures in 2010 will reach 10 million people.

There are other gonorrhea, syphilis, genital herpes, genital warts, non-gonococcal urethritis, the incidence has a greater growth.

On the reasons of the death of our residents

The first five causes of the city

① malignant tumor 135.59 / 10 million

② cerebrovascular disease 111.01 / 10 million

③ heart disease 95.77 / 10 million

④ respiratory disease 72.64 / 10 million

⑤ damage and poisoning 31.92 / 10 million

What are the tasks of clinical microbiology testing?

A: The clinical microbiology test tasks include: 1 to study the pathogen characteristics of infectious diseases: 2 to provide rapid and accurate pathogen diagnosis; 3 to guide the rational use of antibiotics; 4 to monitor the hospital infection.

3. What environmental factors can affect the shape of bacteria?

A: The environmental factors that affect the morphology of bacteria include: 1 culture temperature, time, medium composition, pH, ion concentration, etc .; 2 the body's ecological environment; 3 environment is not conducive to the growth of bacteria, such as drugs, antibiotics, Antibodies, too high salt and so on.

4. Describe the structure of the bacteria and its corresponding function.

A: The basic structure of bacteria include: cell wall, cell membrane, cytoplasm and nuclear quality. Special structures include: flagella, pili, ship, spores and so on.

The main component of the cell wall is peptidoglycan, Clinical Microbiology peptidoglycan is composed of polysaccharide backbone, tetrapeptide side chain and pentapeptide cross-linked bridge three parts. Epicardium is the main structure of the cell wall of Gram-negative bacteria, which consists of three parts: phospholipid, lipoprotein and lipopolysaccharide. The main function of the cell wall is to maintain the inherent shape of the bacteria, from the role of the protection of bacteria.

The main chemical composition of the cell membrane is lipid, protein and a small amount of polysaccharide, its structure is parallel to the lipid bilayer, mostly phospholipids, which inlaid with a variety of proteins, these proteins can be liquid lipid bilayer flow changes. The main functions of the cell membrane are: 1 material transport effect; 2 secretion; 3 respiration; 4 biosynthesis.

Cytoplasm is an important place for bacterial metabolism. The nucleus contains the genetic material of bacteria.

Flagella is a bacterial organ, but also enhances the invasiveness of bacteria. Fimbriae exists on the surface of the cell, can be divided into ordinary pili and fimbriae, Clinical Microbiology in which the former is an adhesive structure, which is fertility, can transmit virulence and drug resistance.

Capsule function includes: 1 protective effect; 2 pathogenic effect; 3 immunogenicity; 4 identification and typing. Spore is a bacterial dormant body, can help the bacteria through the poor living conditions.

In short, both the basic structure and the special structure, have their own functions, to maintain the survival of bacteria and its overall function.
