The Importance Of Clinical Microbiology
Oct 09, 2017



Clinical Microbiology is one of the core courses in the medical examination speciality. Including the basic theory of medical microbiology and the fundamental techniques of clinical microbiological examination, this paper mainly teaches the biological characteristics, clinical significance, test methods, Clinical Microbiology susceptibility test of bacteria to antimicrobial agents, quality control of microbiological examination and nosocomial infection. Through the study of this course, students will be able to master the basic skills of microbiological testing, familiar with the biological characteristics of pathogenic microorganisms in clinical practice.

Clinical Microbiology is a bridge discipline between foundation and clinic, the importance of clinical microbes: microbes are ubiquitous (hospitals), microorganisms are the direct cause of many diseases, microbes are the reference for the development and return of most diseases, Clinical Microbiology even become the main cause of death, Clinical Microbiology the more critical patients it is more active participation

The nature and tasks of clinical microbiology:

① study the pathogen characteristics of infectious diseases;

② provides rapid and accurate diagnosis of etiology;

③ Guide Clinical Rational use of antibiotics;

④ to monitor nosocomial infection.

I. Importance of Clinical Microbiology

(a) The relationship between microorganism and common disease and frequently-occurring disease

1, tuberculosis, viral hepatitis, dental caries and periodontal disease, venereal disease, etc. are cited by pathogenic microorganisms.

(1) Tuberculosis

1/3 people (about 2 billion) are infected with TB, Clinical Microbiology and if no measures are taken, there are 300 million infections in the last 10 years; TB person 20,000,095% in developing countries, each year new occurrence of $number million patients, 75% age in 15~50岁 daily death from TB 8000 people, 3 million per year, 98% In developing countries, the infection rate was 44.5% (2000 survey), with infected persons reaching 550 million. The existing TB patients (active) 4.5 million people die from TB 127,000 people each year, the cause of death in the countryside 9th place, the single disease species 1th. 21.6% of them never received treatment.

(2) Viral hepatitis

There are many, the most harmful to B and C. Only hepatitis B infection rate is more than 10%, that is, Clinical Microbiology more than 100 million HBsAg carriers, chronic hepatitis B disease more than 30 million

(3) Caries and periodontal disease

The Who is listed as the three most important non-communicable diseases after cardiovascular disease and cancer. Dental caries is caused by Streptococcus mutans, and the prevalence rate of dental caries among Chinese students is 13.9% by anaerobic bacteria.

(4) Sexually transmitted diseases

AIDS: The total number of patients in the world at the end of 2000 was 36.1 million, the number of deaths reached 21.8 million, 95% in developing countries. In the first half of 2002, Clinical Microbiology the total number of infections reached 1 million, and if no effective measures were taken, 2010 would reach 10 million people. Other gonorrhea, syphilis, genital herpes, genital warts, non gonococcal urethritis, and so on, the incidence of greater growth.
