Questionnaire of common pathogenic microorganisms

Escherichia coli: It usually exists in the gastrointestinal tract. When it has the characteristics of migration, enterotoxicity, cytotoxicity or invasive toxicity, it can become the main pathogen of watery, inflammatory or bloody diarrhea.

Leptospira: It can be divided into pathogenic leptospira and non-pathogenic leptospira. Pathogenic leptospirosis can cause leptospirosis in humans and animals, which is a widespread disease in humans and animals all over the world.

Escherichia coli O 157:H7: It often lives in the digestive tract of humans and animals and is excreted with feces.

Herpes virus: It infects a wide range of hosts, mainly attacking skin, mucous membrane and nerve tissue, seriously affecting the health of people and other animals.

HIV: A virus that causes defects in human immune system.

Hepatitis B virus: The viruses in this family include hepatotropic DNA virus and avian hepatotropic DNA virus, and it is hepatotropic DNA virus that causes human infection.

Mycobacterium tuberculosis: Mycobacterium tuberculosis is not affected by age, sex, race, occupation and region. Many organs and systems of human body can suffer from tuberculosis, among which tuberculosis is the most common. More than 90% of tuberculosis is transmitted through the respiratory tract.

Dysentery Bacillus: It is the most common pathogen of human bacillary dysentery, and it is the intestinal pathogen of human beings and primates, causing bacillary dysentery.

Foot-and-mouth disease virus: an acute, hot and highly contagious infectious disease that occurs in cloven-hoofed animals such as cattle, sheep and pigs.

Extended data:

Pathogenic microorganisms are diseases that can cause human, animal and plant diseases. Pathogenic microorganisms. Microorganisms refer to those biological groups whose individual volume and diameter are generally less than 65438±0mm, and their structures are simple, mostly single cells, and some even have no cell structure.

The taxonomy proposed by China scholars divides organisms into six fields: virus field, monera field, protozoa field, fungi field, plant field and animal field. It is not difficult to see that microorganisms occupy four of the six realms, so the important position of microorganisms in nature is obvious, and its research objects are also very extensive and rich.
