What do you know about the dangers of invasive bacterial infections?

Introduction: In recent years, people have begun to pay attention to some small problems in their living environment in their daily lives. Some pathogenic microorganisms can cause blood infection through wounds or infection foci in the body, and blood pressure may drop or immunity may be weakened.

Nowadays, more and more attention is paid to invasive bacteria in life, so let's talk about the dangers of invasive bacterial infections, do you really understand?

Invasive bacteria generally refer to the spread of bacteria through the gastrointestinal tract, respiratory tract and other parts, resulting in an inflammatory response in the human body. For example, cough, urgency, painful urination, diarrhea and other symptoms, the main manifestation is an increase in the ratio of white blood cells to neutrophils. In the regular examination, the ratio of leukocytes to neutrophils increases, and the blood precipitation is accelerated, which are all manifestations of bacteria entering the blood.

Therefore, everyone should pay attention to personal hygiene and care for the injured area in daily life.

When the process of the body occurs or there are symptoms of suppuration, bacteria are easy to enter the body through the wound, when the person's immune system is low, it can not fully engulf and kill bacteria, so it leads to more invading bacteria, and the infection caused by it is gradually increasing. At the same time, due to the virulence and quantity of pathogenic bacteria, when the virulence is strong or the number is too large into the human body, it may cause sepsis. Intact ** is a natural barrier to prevent bacteria from invading the human body, and in severe burns, it will create an entrance for bacteria, and when there is necrosis or plasma, it is also conducive to the growth and multiplication of bacteria.

When the patient has a fever caused by bacterial infection, it needs to be carried out as soon as possible**, and to improve the current situation, otherwise it will have a greater impact on health, if you continue to use drugs to fight against bacteria**, then you need to rest well, replenish water in time, regularly conduct blood routine checks, and monitor changes in body temperature at any time. Once there are uncomfortable symptoms, you need to seek medical attention in time, and it is best to find out** to see if it is caused by a viral infection or a bacterial infection.

There is a lot of understanding, it may lead to a person's immunity getting lower and lower, it may affect the kidneys, there may be respiratory infections, it may lead to pneumonia, there may be nausea, vomiting may occur.

What I understand is that the symptoms of this bacterial infection are very strong, it can lead to death, it can also lead to stroke, it can also cause very much damage to your own body, it can also cause yourself to infect, and it can also infect others.

Invasive enteritis: various invasive bacterial infections can cause exudative diarrhea, such as Shigella, Salmonella, invasive Escherichia coli, etc., which can directly invade the small intestine or colon wall, causing mucosal congestion and edema, and inflammatory cell infiltration causing exudation and ulcers.

The child excretes bacillary dysentery stools containing large amounts of white blood cells and red blood cells; Diarrhea can also occur because the colon is unable to absorb fluid from the small intestine adequately due to inflammatory lesions, and some pathogenic bacteria can also produce enterotoxins.

Invasive bacterial infection refers to the spread of bacteria through the gastrointestinal tract, respiratory tract, etc., causing cells to have an inflammatory response. Patients usually have symptoms such as cough, sputum production, excessive urination, urgency to urinate, and diarrhea.

I know. There is a great harm, which will affect health to a certain extent, and at the same time it is likely to lead to infection, and may also lead to a decrease in resistance and immune deficiency, which is very harmful to the body.

I know that this bacterial infection is very harmful, it can lead to accelerated inflammation, which can lead to other complications and worsen the disease.

What are the main invasions of ** infected fungi? What are the main common infections caused?

Correct answer: It mainly includes Monodococcus spp., Cryptococcus spp., Aspergillus spp., Mucormyces spp., and biphasic fungi. Can cause:

Resistant to **, mucosal infection, i.e., eczema-like **candidiasis; visceral infections such as pneumonia, enteritis, etc.; Central nervous system infections such as meningitis, etc.

The invasiveness of bacteria includes the ability to settle, multiply and spread and spread in the body, the invasiveness refers to the ability of bacteria to break through the body's defense function, and bacteria refers to one of the main groups of organisms, which belongs to the bacterial domain and is also the most numerous of all organisms.

Among the low-level parasites, most of the bacteria only have different invasiveness and no toxicity. In higher parasites and obligate parasites, there can be differences in both virulence and invasiveness between strains, and the same strain has both virulence and invasiveness genetic characteristics.

The main influencing factors of sliding culture <> bacterial invasiveness are the surface structure of bacteria, such as common pili, lipoteichoic acid, capsular membrane and capsule-like membrane. Invasive enzymes produced by bacteria, such as plasma coagulase, hyaluronidase, streptokinase, DNase, etc., as well as internal and external toxins produced by bacteria. The invasiveness of bacteria is the ability of bacteria to invade the body and locate in a tissue, adapt to the body's environment, resist defense functions, multiply and spread to other parts. Invasiveness refers to the difference between the infectivity of pathogens and the degree of pathogenicity under the premise of being able to infect and cause disease, which is a quantitative trait.

It may vary from weak to strong, and it may not be specialized for the variety, and its performance does not vary from breed to breed.

Answer]: Invasion refers to the ability of pathogenic bacteria to spread, invade, colonize, and evade immunity from host to host. Plasmids are the genetic material outside the chromosomes of bacteria.

Spores are the dormant bodies of bacteria and are a way for bacteria to continue their life in adverse environments. Parastain particles are the storage form of nutrients and energy for bacteria. Bacteria with sexual pili are fertile and participate in the bonding of Qin Xun bacteria.

Therefore, options A, B, C, and D are not related to the invasiveness of bacteria. Hyaluronidase can decompose hyaluronic acid in the interstitium of cells, which is conducive to the spread of bacteria in tissues, so it is related to the invasion of bacteria. The correct answer to this question is e.

Invasiveness refers to the ability of pathogenic bacteria (including conditional pathogenic bacteria) to break through the body's defenses, invade the body, and grow, multiply, spread and spread in the body. It mainly includes the surface structure of the cell and invasive enzymes. Among them, aggressive enzymes are the aggressive substances you are asking about.

The main invasive enzymes are:

1) Plasma coagulase: its function is to convert fibrinogen in plasma into fibrin, so that plasma coagulation. Coagulants are deposited on the surface of the thallus or around the lesion to protect the bacteria from being engulfed and killed by phagocytes.

2) Hyaluronic acid.

Enzymes: Also known as diffusion factors, they break down connective tissue.

Hyaluronic acid, which plays a role in bonding, expands the intercellular space and increases permeability, which is conducive to the diffusion of bacteria and their toxins to the surrounding and deep layers.

3) Streptokinase: also known as streptococcal fibrinoenzyme, it can activate plasma fibrinogen to fibrinoase, so that fibrin clots can be dissolved, so that bacteria are easy to spread.

4) Collagenase: is a proteolytic enzyme that breaks down collagen in connective tissue.

Promotes the spread of bacteria from tissue to tissue.

5) Deoxyribonuclease: It can hydrolyze the DNA released during the necrosis of tissue cells, so that the viscous pus is thinned, which is conducive to the spread of bacteria.

6) Other soluble substances: leukicidin, which can kill neutrophils.

and macrophages; Hemolysin, which can dissolve cell membranes, white blood cells, red blood cells, and platelets.

Macrophages, nerve cells, and other cells have cytotoxic effects.
