Alcaligenes pneumoniae

Introduction to Alcaligenes Alcaligenetic bacillus pneumonia is a relatively rare bacterial-induced pneumonia. basic knowledge The proportion of illness: 0.021% Susceptible people: no specific people Mode of infection: non-infectious Complications: gastrointestinal bleeding

Alcaligenetic bacillus pneumonia

(1) Causes of the disease

Alcaligenes is a group of obligate aerobic, motivating, non-decomposing gram-negative bacilli, short rod-shaped, or arc-shaped, no spores, mostly non-capsulated, clinically divided into 3 Species, namely Alcaligenes faecalis, Alcaligenes faecalis and A. odorantlon, which are widely found in nature, are normal flora in the intestines of humans and animals, and exist in many places in hospitals. Reports of medicinal origin with contaminated medical devices.

The sputum, urine, septicemia patients' blood, wound secretions, and feces can be isolated from the bacteria. It is common for many pathogens to coexist in infected patients. Two or four kinds of bacteria commonly found in blood specimens and sputum specimens coexist. Most of the bacteria are Acinetobacter, Pseudomonas, Streptococcus and Bacteroides. Of course, there are also cases of pure culture. Two cases of deaths reported in the country are pure culture.

(two) pathogenesis

Alcaligenes is a conditional pathogen, which occurs in patients with low immune function. The most common underlying diseases are malignant tumors, as well as cardiovascular diseases, and rare newborns or immature children.

Alcaligenes bacillus pneumonia prevention

Pay attention to monitoring the resistance rate and drug resistance trend of bacteria in this unit, which is an important basis for guiding clinicians to choose antibiotics correctly.

Alcaligenetic bacillus pneumonia Complications, gastrointestinal bleeding

Alzheimer's disease, Gram-positive bacilli, has a higher proportion of complications, including electrolyte imbalance, gastrointestinal bleeding, DIC, etc.

Alcaligenes bacilli pneumonia symptoms common symptoms anorexia plague-like skin lesions purulent muscle pain chest pain joint pain

Out-of-hospital infections were more common than those in hospitals. They generally had fever, myalgia, joint pain, anorexia, and fatigue. 13% of patients had skin lesions, mainly erythema, nodules, plague-like lesions without eschar or ulcers. The performance of pneumonia has no obvious characteristics with other bacteria, such as cough, chest pain, and purulent sputum.

The nutritional requirements of the bacteria are not high, and it grows in ordinary agar culture dishes. It is important to send the specimens in time, and realize that the pathogenicity of the bacteria as a conditional pathogen cannot be ignored.

Alcaligenetic bacillus pneumonia

The condition is severe, the patient has high fever, chest pain, hemoptysis, and white blood cells are lower, which is 3.8×109/L.

X-ray chest radiographs showed uneven density of large density in the lungs.

Diagnosis and identification of Alcaligenes bacilli

Must be differentiated from Gram-negative bacilli pneumonia.
