What causes Pseudomonas aeruginosa?

Pseudomonas aeruginosa pneumonia is a special type of pneumonia caused by infection with Pseudomonas aeruginosa cells. Symptoms are fever, and severe patients are characterized by high fever, chills, chills and other poisoning symptoms.

Light green purulent sputum is diagnostic, accompanied by chest tightness, wheezing, purple lips, and chest pain. Pseudomonas aeruginosa pneumonia is relatively easy to resist, and it is not easy to kill the respiratory defense mechanism, so it is more difficult, and it is generally possible to accept a regular hospital as soon as possible in the early stage.

The specific reason may be that most patients have underlying diseases and low immunity, so they will be infected with such pneumonia.

It may be due to a decrease in immunity, or an infection of the cells, or it may be caused by inflammation of the lungs, or it may be caused by poisoning of the body, or it may be affected by the body's functions.

Pseudomonas aeruginosa pneumonia(Pseudomonas aeruginosa pneumonia) is caused by Pseudomonas aeruginosa, which is more common in nosocomial infection, and the disease is severe and has a high case fatality rate. It is widely present in humid environments and is easily caused by patients with underlying medical conditions, immunocompromised or intensive care, and mechanical ventilation. In recent years, the case rate has increased significantly, and the case fatality rate is very high.

The symptoms of systemic poisoning are severe, and the body temperature fluctuates greatly, with the peak in the early morning; cough, purulent sputum, and in a few patients, emerald green purulent sputum; Dyspnea, cyanosis, wet rales in patients, empyema in 30% to 50%, confusion in severe cases, easy to complicate respiratory failure, renal insufficiency, shock, electrolyte disorders, heart failure, etc. White blood cell count may be moderately high or normal, blood biochemistry: low potassium, sodium, chloride, liver and kidney impairment.

A positive sputum or pleural fluid culture confirms the diagnosis.

X-ray findings are common as diffuse bilateral bronchopneumonia, which can involve multiple lobes and is common in the lower lobes. Lesions are small abscesses that may coalesce with large infiltrates, multiple small abscesses, or small pleural effusions.

Pseudomonas aeruginosa is the main pathogenic bacterium in the genus Pseudomonas, which is gram-negative bacilli, and the extreme flagella are arranged in single or pairs, the flagella are found to have thermostable antigens, and the cell wall has a phagocytic polysaccharide layer. Although the bacterium is aerobic bacteria, it can grow under anaerobic conditions, grow well in 25 37, and can tolerate high concentrations of hydrochloric acid, disinfectants and general antibiotics, so it is the main pathogen of nosocomial infection, and the colony is flattened ground-glass, producing hemolysin, which is related to the formation of lung infection. 90% of Pseudomonas aeruginosa produces extracellular proteases, resulting in hemorrhagic and necrotizing lesions.

The A-toxin produced by the bacterium is the most virulent and can inhibit the synthesis of its protein in susceptible cells. There are two types of clinical pneumonia, bacteremic pneumonia from hematogenous or mononuclear phagocytic cellsNonbacteremic pneumonia is caused by inhalation of upper respiratory secretions.

Complications of this disease include: bacteremia, respiratory failure, renal insufficiency, heart failure, pleural effusion, gastrointestinal bleeding, etc.

1. What is good to eat for Pseudomonas aeruginosa pneumonia?

Food should be highly nutritious, light, easy to digest, and liquid, especially fruit juicesFresh fruits and vegetables;Oily fish, eggs, and other foods rich in vitamin A.

2. What foods should not be eaten for Pseudomonas aeruginosa pneumonia

Avoid spicy and greasy foods. Do not eat big fish, big meat, too greasy products, pneumonia patients should not add chili, pepper, mustard, Sichuan pepper and other condiments to the meal. Quit smoking and drinking.

It is not advisable to eat sweet and warm fruits, such as peaches, apricots, plums, oranges, etc.

Avoid eating raw and cold:A variety of iced beverages;⑵.

Melons and fruits that are cold in nature: including watermelon, pear, banana, kiwifruit, etc.;The second is to abstain from sour foods: such as vinegar, sour cabbage, kimchi, hawthorn, black plum, sour citrus, etc.;Astringent foods:

Such as ginkgo seeds, lotus roots, unripe persimmons, begonias, etc.

The symptoms of this disease are a series of discomforts such as chest tightness, cough, sputum production, and fatigue. If the onset is particularly long, it will cause very much damage to the lungs.

I don't know it specially, but this is the name of a disease announced in 2018, which is a respiratory disease that can cause harm to the body, cough, and fever.

Answer]: Pseudomonas aeruginosa produces pyocyanin and Pseudomonas aeruginosa fluorescein. Pseudomonas fluorescein is produced.

Pseudomonas aeruginosa is a conditional pathogen and one of the main pathogens of nosocomial infection. Patients with metabolic diseases, hematologic diseases, and malignant tumors, as well as patients after surgery or some **, are susceptible to infection with this bacterium.

It often causes postoperative wound infection, and can also cause bedsores, abscesses, purulent otitis media, etc. The foci of infection caused by this bacterium can lead to hematogenous spread and bacteremia and sepsis. Infection with Pseudomonas aeruginosa after a burn can cause death.

Many infections caused by Pseudomonas aeruginosa occur in debilitated or immunocompromised hospitalized patients, and it is the second most common pathogen of intensive care unit infections and a common cause of ventilator-associated pneumonia. In addition to nosocomial infection, people with HIV can easily acquire the bacterium in the community, and once infected with Pseudomonas aeruginosa, they often present with signs of advanced HIV infection.

The baby is now six and a half months old, a month ago, found hematuria, hospitalized**, urine culture is Pseudomonas aeruginosa infection, after ten days of infusion**, urine culture is normal, discharge a week after re-examination of urine culture, still Pseudomonas aeruginosa; After being transferred to the hospital**still infused antibiotics**, twelve days, the hospital examination was normal, and the urine culture was rechecked seven days after discharge, and it was still Pseudomonas aeruginosa, and I asked for advice from an experienced doctor in pediatrics!

Pseudomonas aeruginosa (formerly known as Pseudomonas aeruginosa.

All kinds of water, air, normal people's **,

respiratory tract and. The intestines and so on are present.

It is quite expensive to be infected with this bacterium, and there are more ICU infections in general hospitals. Not to be taken lightly.

This bacterium is a conditional pathogenic bacterium.

It is the main cause of nosocomial infection.

One of the pathogenic bacteria. Trouble.

Metabolic diseases.

Hemopathy. and patients with malignant tumors, as well as postoperative or post-operative patients are susceptible to infection.

It often causes postoperative wound infection, and can also cause pressure sores, abscesses, and purulent otitis media.

Wait. Infections caused by this bacterium.

Lesions can lead to hematogenous spread and bacteremia develop.

Septicemia. Infection with patina after burns.

Pseudomonas. Can cause death.

It has a strong effect on Pseudomonas aeruginosa.

Antimicrobials. There are semi-synthetic penicillins, such as aloxicillin and piperacillin, of which piperacillin is the most commonly used.

Third-generation cephalosporins.

Ceftazidime.

The effect of cefoperazone is stronger. Other.

Lactam. class of drugs.

Imipenem. and aztreonam; Aminoglycosides such as: gentamicin, tobramycin, amikacin.

and isopamicin.

Fluoroquinones such as: ofloxacin, ciprofloxacin and.

Froloxacin. Wait. "Ceftazidime" or "ofloxacin" is recommended.

1. If it is determined that the pathogen of lung infection is Pseudomonas aeruginosa, it will be more troublesome, because the bacterium is easy to induce enzyme production, resulting in antibiotic resistance, it is recommended to have multiple sputum culture + drug sensitivity, according to the drug susceptibility test combined with antibiotics, there are many options to choose from: such as aminoglycosides (amikamycin) + cephthromycin (ceftadine), or quinolones (ciprofloxacin) + cephalosporin (ceftadine), or ciprofloxacin + lactams containing inhibitors (tejicin), Aminoglycosides (amikamycin) + tejcin, or ciprofloxacin + carbapenems (meping), etc.

2. The course of treatment should be long, and the combination of drugs should be effective.
