Pathogenic microorganisms are divided into four categories, which are the most harmful

The first category is the most harmful.

1. A class of animal pathogenic microorganisms. Foot-and-mouth disease virus, highly pathogenic avian influenza virus, swine vesicular disease virus, African swine fever virus, African horse fever virus, rinderpest virus, peste des petits ruminants virus, infectious mycoplasma filaformis in bovine pleuropneumonia, bovine spongiform encephalopathy, scrapie.

2. Class II animal pathogenic microorganisms. Swine fever virus, Newcastle disease virus, rabies virus.

Sheep pox goat pox virus, bluetongue virus, rabbit viral hemorrhagic virus, Bacillus anthracis, Brucella.

3. Three types of animal pathogenic microorganisms. A variety of zoonotic pathogenic microorganisms: low pathogenic influenza virus, pseudorabies virus, Clostridium tetani, Clostridium emphysema, Mycobacterium tuberculosis.

Mycobacterium paratuberculosis, pathogenic Escherichia coli, Salmonella.

Pasteurella, etc.

1. The first category of pathogenic microorganisms are 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 extinct.

2. The second type of pathogenic microorganisms are 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.

3. The third type of pathogenic microorganisms 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, and the microorganisms that rarely cause serious diseases after laboratory infection and have effective and preventive measures.

4. The fourth category of pathogenic microorganisms are microorganisms that do not cause human or animal diseases under normal circumstances.

Among them, the first and second categories of pathogenic microorganisms are collectively referred to as highly pathogenic pathogenic microorganisms.

Excludes microorganisms**.

state according to pathogenic microorganisms.

The degree of infectiousness and harm to individuals or groups after infection, and the implementation of classified management of pathogenic microorganisms, Ministry of Agriculture.

A taxonomic list of animal pathogenic microorganisms has been promulgated, which divides animal pathogenic microorganisms into:

1. The first category is 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. Such as foot-and-mouth disease virus, highly pathogenic avian influenza.

Virus, bovine spongiform encephalopathy.

Cause of disease. 2. The second category is 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 people, and animals and animals. Such as bluetongue virus, rabbit viral hemorrhagic virus, Bacillus anthracis.

Brucella. <>

Certain pathogens.

After repeated exposure to certain chemical drugs, their reactivity is constantly weakened, so that 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 have a history of loss, so it is necessary to strictly grasp the indications in the first disease to prevent drug abuse.

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.

The first category is the most harmful, and the first category is pathogenic microorganisms.

It 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.

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

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 humans and people, animals and animals. It has characteristics of high individual hazard and low group hazard, such as highly pathogenic avian influenza.

Viruses, Brucella, etc.

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

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

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.

Class I pathogenic microorganisms.

It 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.

If highly pathogenic pathogenic microbial species (viruses) or samples are stolen, robbed, lost, or leaked during transportation or storage, the carrier, escort, and preservation institution shall take necessary control measures, and report to the competent department of the carrier unit, the unit where the escort belongs, and the competent department of the preservation institution within 2 hours, and at the same time report to the competent department of people's health or veterinary medicine at the county level where it is located.

In the event of theft, robbery, or loss, it shall also be reported to the public security organs; The competent department of health or veterinary medicine that receives the report shall report to the people at the same level within 2 hours, and at the same time report to the competent department of health or veterinary medicine and the competent department of health or veterinary medicine at the higher level.
