It takes a chronic course with relapses.
Diagnosis and treatment of psittacosis
based on data from epidemiological history (contact with
birds), clinical presentation, radiographic findings and
laboratory studies. In the blood, marked leukopenia, sharp
increased erythrocyte sedimentation rate.
A specific method of diagnosis is
allergic intradermal test with ornitoznoy allergen that
carried out with 1-5 days of illness. Of the serological tests used
complement binding reaction, as well as indirect reaction
is carried out in a hospital. Apply tetracycline antibiotics or
