Neisseria catarrhalis pneumonia

Introduction to Nesakartococcus pneumonia Neisseria catarrhal (referred to as catarrhal) is a Gram-negative diplococcus different from B. catarrhalis. It is known that the bacteria can cause various diseases such as meningitis, endocarditis, urethritis, conjunctivitis in infants and children, keratitis, septicemia and septic joints without lymphoma hyperplasia Inflammation, etc., but rarely seen. basic knowledge The proportion of illness: 0.005% Susceptible people: no special people Mode of infection: non-infectious Complications: sepsis meningitis endocarditis

Neisseria globulin pneumonia

(1) Causes of the disease

Katabanhan is divided into 2 genera:

1 Moraxella: including 7 strains of Moraxella catarrhalis, Moraxella urtica, and M. bovis.

2 Branhamia: catarrhalis, until the 1980s, has been considered to be the normal flora of the upper respiratory tract of healthy people, after which the bacteria were found in the upper and lower respiratory tract, and people gradually improved the conditional disease. Bacteria, often based on the understanding of the bacteria, agree that the bacteria can also be a pathogenic bacteria, the upper respiratory tract is the colony of the bacteria and the invasion portal that causes infection, and it is also reported that it is part of the human genital flora.

(two) pathogenesis

From acute and chronic bronchitis, bronchitis, pneumonia, especially in the case of underlying diseases with low immunity (such as connective tissue disease, septicemia, etc.), Nesica can be isolated from sputum and airway secretions. He cocci, until the 1980s, has always believed that the bacteria is a normal flora of the upper respiratory tract of healthy people. Since then, the bacteria have been found in the upper and lower respiratory tract, and people have gradually improved the understanding of the conditional pathogens, often based on the understanding of bacteria. It is recognized that the bacteria is also a pathogenic bacteria. The upper respiratory tract is the invading portal of the colony and infection, and it is also reported to be part of the human genital flora.

Nestica bacillus pneumonia prevention

Comprehensive measures are taken to prevent, first, to enhance the patient's resistance, and second, to strictly disinfect the medical staff, and to have a good concept of sterility and regular operation.

Neisseria globulin pneumonia complications Complications sepsis meningitis endocarditis

Can cause sepsis, combined with meningitis, endocarditis.

Nesicacin cocci pneumonia symptoms Common symptoms Meningitis dry sputum sound wet sputum spurt

Gao Xun et al concluded that the clinical features of 26 cases are that the clinical manifestations are not typical and are easily confused with other bacterial pneumonia. The following manifestations should be considered:

1. Middle-aged and elderly patients have basic diseases such as chronic lung disease, and have long-term antibiotics, hormones or immunosuppressive applications.

2. Acute onset, there are obvious symptoms or signs of respiratory infection, especially those with purulent sputum or fever.

3. X-ray chest radiograph has inflammatory infiltrative lesions, which are flaky and blurred, scattered.

4. White blood cell count and neutrophils do not increase, or have a tendency to decrease.

There were two or more basic diseases in 26 cases, and the main disease statistics were selected: 10 cases of chronic bronchitis, 5 cases of pulmonary tuberculosis, 2 cases of pulmonary heart disease, 1 case of chronic asthma, and 18 cases of long-term antibiotics, including 11 cases of combined use of hormones. 5 cases of anti-tuberculosis drugs were applied.

All 26 patients had acute onset, cough and cough all, including 11 cases of white sticky sputum, 15 cases of purulent sputum, 17 cases of fever (65.4%), of which 6 cases were 37.5 ~ 38 °C, 38.1 ~ 39 °C Of the 7 cases, 4 cases above 39 °C, 12 cases (46.2%) with sputum, 9 cases (34.6%) with dyspnea, 7 cases (26.9%) with cyanosis, 6 cases of chest pain, pulmonary signs: wet voice 10 For example (38.5%), 7 cases (26.9%) had dry voice, 9 cases (34.6%) with dry voice and wet voice, and 1 case (3.8%) with consolidation.

Nastica bacillus pneumonia check

The sputum cultured positive specimens were 52 times, and the blood plate was obtained.

X-ray chest radiographs can be invaded both sides of the lungs, 23 cases of patchy shadows, including 9 cases of large shadows, 3 cases of lung abscess.

Diagnosis and identification of Nesicacinococcus pneumonia

diagnosis

The sputum culture or smear staining of patients with Nesicacin pneumonia can often make a reliable diagnosis. Semi-quantitative culture of bacteria may be impure, but if Branhamella is the dominant bacteria, it can also make judgments, fast and simple methods. Still Gram staining, because meningococcal seldom causes pneumonia, so if you see a lot of polymorphonuclear cells, mucus and a large number of intracellular and extracellular Gram-negative diplococcus, it may be Branhamella. Branham's bacteria grows well on 5% defibrinated sheep blood agar and chocolate nutrient agar, which can form colorless colonies, positive for oxidase test, and can not be identified in morphology with Neisseria. Branhamella does not ferment glucose, maltose Lactose and sucrose, the biochemical reaction of only N. sphaeroides from Neisseria isolated from patient specimens is the same, and can be identified according to other characteristics of B. hanii.

Differential diagnosis

Must be differentiated from other bacterial pneumonia.
