What examination should Chlamydia psittaci pneumonia do?
summary
Chlamydia psittaci pneumonia is an early lung disease (at the end of the 17th century). At that time, parrots were considered to be the host of the pathogen, and the disease caused by it was called Chlamydia psittaci pneumonia. The incubation period of Chlamydia psittaci pneumonia was 1-2 weeks. What examination should Chlamydia psittaci pneumonia do? Next, I'd like to share my views with you.
What examination should Chlamydia psittaci pneumonia do?
When psittacosis affected the heart, ECG showed myocarditis. The X-ray manifestations of psittaci fever were mainly pulmonary infiltration, such as diffuse bronchopneumonia or interstitial pneumonia. The absorption of lung lesions was slow.
Micro immunofluorescence test (MIF) is the international standard and the most commonly used serological diagnostic method for Chlamydia. However, in the diagnosis of Chlamydia psittaci, we should be cautious. In addition to patients with a history of bird contact, serum samples should be tested for Chlamydia trachomatis, Chlamydia pneumoniae and Chlamydia psittaci antibodies at the same time, and antibody titers should be compared, The highest incidence rate of Chlamydia is the highest infection rate, so as to determine whether it is partrid chlamydia. Because there may be cross serological cross reactions among three Chlamydia species, the clinical symptoms of Chlamydia pneumoniae pneumonia are similar to those of Chlamydia pneumoniae pneumonia, but the incidence of the former is far lower than that of the latter. The serological diagnostic criteria were: IgG ≥ 1 ∶ 512 and (or) IgM ≥ 1 ∶ 32 in MIF test. After excluding the false positive caused by rheumatoid factor (RF), it can be diagnosed as recent infection. The increase of double serum antibody titer 4 times or more can also be diagnosed as recent infection.
The most reliable method is to culture Chlamydia psittaci, take the swabs of nasopharynx or retropharyngeal wall, tracheal and bronchial aspirates, alveolar lavage fluid and other specimens for culture, and the isolates can be identified by species-specific monoclonal antibodies of Chlamydia psittaci. It is very helpful to detect the above samples by PCR test, but we need to pay attention to the quality control to prevent false positive results.
matters needing attention
1. Patients with psittacosis should be isolated and sputum should be disinfected. 2. Avoid contact with infected birds or birds, such as parrots, to prevent infection. Workers in poultry processing industry should pay special attention to avoid occupational contact. 3. Strengthen the management of international import quarantine and bird appreciation. If sick animals are found, they can be slaughtered or isolated for treatment, such as adding chlortetracycline in feed, or soaking seeds with tetracycline or chlortetracycline.
