There are many kinds of Gram-negative bacilli that can cause pneumonia, and the clinical manifestations are similar to the lack of specificity of the auxiliary examination. Therefore, the diagnosis of Escherichia coli pneumonia requires clinical combination of pathogens. Symptoms of pneumonia, long-term use of antibiotics or the history of immunosuppressive agents, accompanied by gastrointestinal symptoms, and even psychiatric symptoms, rapid progression of the disease and empyema, should consider the disease smear test can distinguish pathogens Whether it is positive for Gram-negative bacilli culture should exclude the contamination of oropharyngeal colonization bacteria. Therefore, qualified sputum specimens should be taken first, that is, the proportion of leukocytes and epithelial cells in sputum smear is more than 2.5. The bacillus can confirm the disease. Diagnosis can also be established by the culture of Escherichia coli in pleural fluid and blood samples. DNA probes or PCR methods can be used wherever possible. If pneumonia secondary to urinary tract infection, and urinary tract and sputum culture Escherichia coli are positive, there is also diagnostic value.

Differential diagnosis

The differential diagnosis of this disease and other bacterial pneumonia mainly depends on the establishment of pathogens, and sometimes it is difficult to identify clinical manifestations alone.
