Chlamydia psittaci ( chlamydia psittaki) causes anthropozoonosis diseases that develop as a result of human infection with professional, less often household contact with animals and birds.

Ornithosis - a disease characterized by primary damage to the respiratory organs, as well as the nervous system, parenchymal organs, with the phenomena of general intoxication.

The causative agent was discovered in 1875 by T, Jurgens. The disease caused by Chlamydia psittaci was called "psittacosis" (from the Greek psittakos - parrot), as it arose after contact with parrots. However, later it was noticed that it is possible to get infected not only from parrots, but also from other birds, and the disease was called "ornithosis" (from Latin ornis - a bird).

Pathogenesis and symptoms of ornithosis

The entrance gates for the pathogen are the mucous membranes of the respiratory tract. The causative agent multiplies in the epithelium of the bronchial tree, in the alveolar epithelium, and also in macrophages. Inflammation develops, cells are destroyed, bacteremia, toxemia, allergization of the macroorganism, lesion of the parenchymal organs occur. In the clinical picture of ornithosis, the symptoms of bronchial and pulmonary lesions are of paramount importance. There are complications from the cardiovascular (thrombophlebitis, myocarditis), central nervous systems, etc. A generalized form of chlamydial infection is possible.

Immunity has an unsterile nature, mainly cellular. Possible repeated diseases. The bacterium is able to persist in the respiratory organs after a clinical recovery. Long-term hypersensitivity to the pathogen antigens may persist, which are detected when intradermal tests are performed.

Epidemiology of ornithosis

The source of infection are wild, domestic and ornamental birds - infected or asymptomatic carriers. Infection from ectoparasites of birds and rodents is also possible. From person to person, the disease is transmitted very rarely.

The mechanism of infection is respiratory, the pathway of airborne and airborne infection when inhaled dust contaminated by secretions of sick birds.

People's susceptibility to ornithosis is high. The disease is of a professional nature - people who work on poultry farms suffer from a bowl, as well as owners of ornamental birds.

Microbiological diagnosis of ornithosis

The main method of diagnosing chlamydia psituac is serological. IgM was determined using RIF and ELISA.

Isolation of the pathogen from the blood (the first days of the disease) and sputum is used rarely and is possible only in specialized laboratories.

Treatment of ornithosis

Treatment of ornithosis is the use of antibiotics tetracycline and macrolides.

Prevention of ornithosis

Specific prevention of ornithosis is not developed. Prevention of infection of people is based on the conduct of veterinary-sanitary and medical-sanitary measures (timely identification of sources of infection, disinfection of premises, automation of production, etc.).
