Enterococcus pneumonia

Introduction to Enterococcus pneumonia Acute lung suppurative inflammation caused by Enterococcus pneumoniae enterococcus is a minority of bacterial pneumonia, mostly in-hospital infections, and has received increasing attention and attention in recent years. basic knowledge The proportion of illness: 0.005% Susceptible people: no specific population Mode of infection: non-infectious Complications: sepsis

Enterococcus pneumonia

Cause:

Enterococcus is originally attributed to Streptococcus, Streptococcus, also known as Group D Streptococcus or Streptococcus faecalis. It is a Gram-positive bacterium. According to DNA homology analysis, it has been listed as a genus, Enterococcus. It mainly includes Enterococcus faecalis (E, faecaL, also known as Streptococcus faecalis) and Enterococcus faecalis (E, faecium, also known as Streptococcus urinary), and the former is more common, Enterococcus is generally not hemolyzed, Enterococcus Salt-tolerant, heat-resistant, can grow in medium containing 6% NaCl, and can survive for 30 minutes at 62 °C. Enterococcus is the normal flora of human digestive tract, and the oropharynx can also be cultured to Enterococcus faecalis. It is weak in disease and does not cause disease under normal circumstances. However, invading human tissues can cause corresponding infection. If the enterococci that are parasitic in the oropharynx are inhaled into the respiratory tract, especially when it is treated with nasal feeding nutrition and mechanical ventilation, it may cause intestinal disease. Coccidial pneumonia, in which the risk of Enterococcus faecalis is significantly higher than that of Enterococcus faecalis, invasive procedures and widespread use of broad-spectrum antibiotics are closely related to infection with Enterococcus.

Pathogenesis:

Enterococcus has been considered to be a low-virulence microorganism, rarely causing fatal infections. In the past decade or more, enterococci have caused serious infections, and reports of higher mortality have increased. The remarkable feature of enterococci infection is in the hospital. The proportion of infections is increased, especially in patients with underlying diseases such as major surgery, immunosuppression, organ transplantation and heart, lung, liver and kidney diseases. Previous reports of extrapulmonary infections have been reported, but lung infections have occurred in recent years. The rate report has gradually increased.

Enterococcus pneumonia prevention

Early detection and early diagnosis are the key to the prevention and treatment of this disease. People with cardiovascular disease, lung disease, diabetes, alcoholism, cirrhosis and immunosuppression (such as HIV infection, renal failure, organ transplant patients, etc.) can be injected with pneumonia vaccine. Strengthening physical exercise, enhancing physical fitness, and reducing risk factors such as smoking and alcoholism, and improving their own immunity are effective ways to prevent pneumonia.

Enterococcus pneumonia complications Complications sepsis

A small number of patients can be combined with enterococcal sepsis. Chronic obstructive pulmonary disease, diabetes, chronic heart and kidney dysfunction, chronic liver disease, respiratory rate >30 beats / min; pulse 120 beats / min; blood pressure <90/60mmHg; body temperature 40 ° C or 35 ° C; There are extrapulmonary infections such as meningitis and even sepsis (infectious poisoning). X-ray chest lesions involve more than one lobe, voids, rapid spread of the lesion, or pleural effusion.

Enterococcus pneumonia symptoms common symptoms shock bacteremia, purulent sputum, acute chest pain, sepsis, intravascular coagulation

Enterococcus pneumonia is very rare in the type of bacterial pneumonia. Its clinical manifestations are not much different from pneumonia caused by general purulent bacteria. Symptoms include fever, cough, sputum, chest pain, shortness of breath, etc. The signs are solid signs of pneumonia. A small number of patients can be combined with enterococcal septicemia, shock and disseminated intravascular coagulation (DIC), which is critically ill and can lead to death. It is mainly seen in patients with nosocomial infections. X-ray chest radiographs show increased patchy density or increased leaf density. Shadow, peripheral blood examination showed more white blood cells, blood bacterial culture can be positive when combined with bacteremia or sepsis.

Examination of enterococci pneumonia

Peripheral blood examination showed that white blood cells increased, and blood bacterial culture was positive when combined with bacteremia or sepsis.

X-ray chest radiographs showed increased patchy density or increased leaf density.

Diagnosis and identification of enterococci pneumonia

Clinically, relying mainly on sputum or anti-contamination brush, fiberoptic bronchoscopy in the lower respiratory tract or bronchoalveolar lavage (BAL), taking the lavage fluid for bacterial quantitative culture and identification can be diagnosed, if the patient has suppurative pneumonia, and There is a history of invasive operation such as nasal feeding nutritional therapy, clinically treated with penicillin or cephalosporin antibiotics, the possibility of enterococcal pneumonia should be considered, and further pathogen examination should be carried out. Enterococcus pneumonia should be associated with pneumonia caused by other purulent bacteria. Identification, mainly rely on pathogen examination.

Symptoms and signs of enterococci pneumonia patients have no special help for pathogenic diagnosis. Clinically, relying mainly on anti-pollution brush, fiberoptic bronchoscopy in the lower respiratory tract or bronchoalveolar lavage (BAL) irrigation solution for bacterial quantitative culture and identification. Diagnosis, if the patient has suppurative pneumonia, and has a history of invasive operation such as nasal feeding nutritional therapy, clinically treated with penicillin or cephalosporin antibiotics, the possibility of enterococcal pneumonia should be considered, and further pathogen examination, enterococci Pneumonia should be differentiated from pneumonia caused by other purulent bacteria, mainly relying on pathogenic examination.
