There are those pathogenic microorganisms in the first category, and pathogenic microorganisms are d

The first category of pathogenic microorganisms stipulated by China is all viruses, and there are no bacteria, such as smallpox-like virus, smallpox virus, oriental equine encephalitis virus, just overheat virus, Ebola virus, Venezuelan virus, yellow fever virus, etc., a total of 29 viruses.

Currently yesPathogenic microorganismsIt is divided into four categories, one is the strongest and the four are the weakest.

Category 1: microorganisms that can cause very serious diseases in humans or animals, as well as microorganisms that have not yet been discovered or have been declared eliminated in China. It has high individual hazard and high group hazard, and the diseases caused by it generally cannot be **, such as smallpox virus and Ebola virus.

Wait. Category II: microorganisms that can cause serious diseases in humans or animals, and are relatively easy to spread directly or indirectly between people and people, animals and people, and animals and animals. It has characteristics of high individual hazard and low group hazard, such as highly pathogenic avian influenza.

Viruses, Brucella, etc.

Category 3: microorganisms that can cause human or animal diseases, but generally do not pose serious harm to humans, animals or the environment, have a limited risk of transmission, and have effective ** and preventive measures. It has the characteristics of moderate individual hazard and limited group hazard, such as hepatitis A virus and hepatitis B virus.

Wait. Category 4: Microorganisms that do not normally cause diseases in humans or animals. It has low individual hazard and low group hazard.

Related information. Pathogenic microorganisms refer to microorganisms or pathogens that can invade the human body and cause infections or even infectious diseases. Among the pathogens, bacteria and viruses are the most harmful. Pathogenic microorganisms refer to prions.

Fungi, bacteria, spirochetes, mycoplasma.

Rickettsia, chlamydia, viruses.

After some pathogens are repeatedly exposed to certain chemical drugs, their reactivity is constantly weakened, so that finally the pathogen can resist the drug without being killed or inhibited, which is the pathogen's tolerance to the drug, which is called drug resistance.

or drug resistance. The main cause of drug resistance is insufficient dosage of a drug or long-term use of a drug. Many bacteria develop resistance.

The pathogen develops resistance, often with less or no effect at all. Drug-resistant strains are hereditary, so it is necessary to strictly grasp the indications when it comes to ** diseases to prevent drug abuse.

Pathogenic microorganismsIt is divided into four categories, of which the first.

The first and second categories are highly pathogenic pathogenic microorganisms.

Category I: microorganisms that cause very serious diseases in humans or animals; and microorganisms that have not yet been discovered or eliminated in our country.

Category 2: Microorganisms that cause serious diseases in humans or animals and are more likely to spread among humans, humans, animals, and animals.

Category 3: It can cause diseases in humans or animals, but generally does not pose a serious hazard, and the risk of transmission is medicalMicroorganisms that rarely cause serious illness after laboratory infection and have effective ** and preventive measures.

Category IV: Microorganisms that do not normally cause disease in humans or animals.

Conditions for collecting samples of pathogenic microorganisms.

The collection of samples of pathogenic microorganisms shall be in compliance with biosafety.

Requested conditions:

1) Have equipment that is compatible with the level of biosecurity required to collect pathogenic microbial samples;

2) Staff with relevant professional knowledge and operational skills;

3) have effective measures to prevent the spread and infection of pathogenic microorganisms;

4) Technical methods and means with the quality of pathogenic microbial samples.

Where highly pathogenic pathogenic microorganisms are collected, special attention should be paid to preventing their spread and infection, and detailed records should be made of samples**, collection processes, methods, etc.

The third type of pathogenic microorganisms has the characteristics: they can cause human or animal diseases, but generally do not pose serious harm to people, animals or the environment, the risk of transmission is limited, laboratory infection rarely causes serious diseases, and has effective ** and preventive measures.

The state divides pathogenic microorganisms into four categories according to the infectiousness of pathogenic microorganisms and the degree of harm to individuals or groups after infection:

The first category of pathogenic microorganisms refers to microorganisms that can cause very serious diseases in humans or animals, as well as microorganisms that have not yet been discovered or have been declared eliminated in China.

The second category of pathogenic microorganisms refers to microorganisms that can cause serious diseases in humans or animals and are relatively easy to spread directly or indirectly between humans and people, animals and animals.

The third category of pathogenic microorganisms refers to microorganisms that can cause human or animal diseases, but generally do not pose serious harm to humans, animals or the environment, have limited transmission risk, rarely cause serious diseases after laboratory infection, and have effective ** and preventive measures.

The fourth category of pathogenic microorganisms refers to microorganisms that do not normally cause diseases in humans or animals.

The first and second categories of pathogenic microorganisms are collectively referred to as highly pathogenic pathogenic microorganisms.

Depending on the location of respiratory tract infection, the common pathogenic microorganisms are:

1. Pharyngitis. Hemolytic streptococcus and a variety of anaerobic bacteria, coronavirus.

Rhinovirus, adenovirus.

Parainfluenza virus, influenza virus.

2. Sinusitis: Streptococcus pneumoniae, Haemophilus influenzae, Staphylococcus aureus, Streptococcus pyogenes, rhinovirus, influenza virus, parainfluenza virus.

3. Epiglottitis: Haemophilus influenzae, Streptococcus pyogenes, anaerobic bacteria.

4. Laryngitis: influenza virus, rhinovirus, coronavirus, hemolytic streptococcus, Haemophilus influenzae, Streptococcus pneumoniae.

5. Bronchitis: respiratory syncytial virus.

Parainfluenza virus, influenza virus, adenovirus, Mycoplasma pneumoniae.

6. Acute bronchitis: influenza virus, rhinovirus, adenovirus, measles virus, Mycoplasma pneumoniae, Chlamydia pneumoniae, pertussis bacillus.

7. Socially acquired pneumonia: Streptococcus pneumoniae, Streptococcus pyogenes, Mycoplasma pneumoniae, Staphylococcus aureus, Klebsiella pneumoniae.

Haemophilus influenzae, Legionella spp.

8. Nosocomial pneumonia: Enterobacteriaceae such as Escherichia coli, Klebsiella pneumoniae, Proteus, etc.; Pseudomonas aeruginosa.

and other Pseudomonas; Methicillin-resistant Staphylococcus aureus, fungi, etc.

9. Interstitial pneumonia.

Respiratory syncytial virus, influenza virus, adenovirus, Chlamydia pneumoniae.

Pathogenic microorganisms are usually divided into three categories:1. Non-cellular microorganisms.

They do not have a typical cellular structure, nor do they have an enzyme system capable of producing energy, and need to grow and reproduce in other cells. For example, the virus is responsible for the new crown pneumonia, and hepatitis B and AIDS are all caused by viruses.

2. Prokaryotic cell-type microorganisms.

Such pathogenic microorganisms do not have a complete nucleus and imperfect organelles, including bacteria, actinomycetes, chlamydia, mycoplasma, rickettsia, spirochetes, etc.

3. Eukaryotic cell-type microorganisms.

These microorganisms have nuclear membranes and complex organelles, including fungi and protozoa.

Effects on the human body.

Whether pathogenic microorganisms become ill after invading the human body also depends on the body's immune function. Infection and immunity are a contradiction, and their outcome depends on the strength of both the pathogen and the host. If the host is strong enough, infection can not form at all; Even if an infection is formed, the pathogen will most likely die out gradually, so the patient**; If the host is weak and the pathogen is ferocious, the infection spreads and the patient dies.
