What is ornithosis
Ornithosis (outdated name «psittacosis») - acute infectious
Disease characterized by general intoxication, defeat
Lungs, nervous system, increased liver and spleen.
Disease pathogen - bond intracellular parasite
Chlamydia Psittaci, belonging to the family of chlamydia. Outside cells
The host metabolic functions of these bacteria are reduced to a minimum and
They are difficult to identify; they can be highlighted by infection white
mice or chicken embryos, as well as in tissue cultures. Chlamydia
inactivate when heated above 70 °With and under action
Disinfectants. In the external environment, preserved up to 3 weeks.
The main paths of infection - air-dust and air-drip.
The pathogen was revealed in 140 types of domestic and wild birds; Last
allocate it with feces and separated from nasal moves. Chlamydia
Enter on feathers, fluff, eggs and various environmental objects.
It should be remembered that the epidemiological significance of various birds
Nonodynakova; In nature, the main reservoir of the pathogen is
waterfowls, and among synanthropic birds the main danger
represent pigeons (infected to 50% of the population). Infection for
Contact with a sick person is rarely observed, as it highlights
little pathogens and in his body their virulent properties
Weaken. Some authors indicate a possible epidemic
Danger of sheep, cows, cats and dogs; Well detected spontaneous
infection of certain types of rodents.
In the human body, the causative agent penetrates mainly through
mucous membrane of respiratory organs (when inhaled infected
dust). The lesions of the upper respiratory tract during ornithosis are missing,
However, in bronchi, according to bronchoscopy, pronounced
Inflammatory changes. Part of the patients in the mouth of the bronchi
there is a mucosa plug that fascinating the clearance, which can
lead to the development of atelectasis. The pathogen breeds B
epithelial (upper skin layer) cells, then penetrates blood, caused by
The development of general intoxication (poisoning), as well as the defeat of a number of bodies (liver,
spleen, myocardium, brain). People with a good immune system infection
may leak asymptomatic (the so-called inapparanting form). W
most patients cleansing the body from the causative agent occurs in
within a few weeks, but sometimes it is possible to preserve chlamydia in
by the body up to 8 years (chronic form of ornithosis). With ornithosis
Immunity unstable, repeated diseases were observed after 1-2
of the year.
Symptoms of ornithosis
The incubation period usually lasts 8-12
Days. Ornithoses can flow both in typical (pneumonic) and
In atypical (meningopnemia, meningitis, ornithosis without defeat
lungs) forms of varying severity. Pneumonic form of ornithosis
It begins acutely with the phenomena of general intoxication (fever, chills,
Headache, Weakness, Malgy, etc.). Symptoms of lesion upper
The respiratory tract is not marked. In the first days there is also no signs
Lightweight and pleura. Body temperature in most patients
Above 39°WITH.
Against the background of general intoxication from the 2-4th day of the disease
appear signs of respiratory lesion. Cashel arises,
which can be both dry and with a viscous mocoid,
Sometimes mucous-purulent or with streysts. Half patients
Pains in the chest are marked, usually cringers associated with
Act of breathing. At the same time, clinical signs appear
Pneumonia, which is mainly localized in the lower lobes,
and the lower right share is amazed 2 times more often than the left. TO
The end of the 1st week in the majority (70%) of patients marked an increase
Liver and spleen.
Signs of pronounced intoxication are saved to
The 7-10th day of the disease, then gradually begin to decrease; wherein
Changes in the lungs and other organs are saved. Body temperature
It is usually lithuanically lithuanically, but after that feeling the patient
still not normalized. With moderate and heavy ornithosis forms full
Recovery occurs only after 2-2.5 months.
Chronic form of ornithosis in recent years is rarely observed.
Complications for ornithosis may be due to both chlamydia and
layered secondary infection. The most dangerous are
myocarditis and thrombophlebitis followed by lung thromboembolism
Arteries. Diagnostics is based on clinical data taking into account
Epidemiological Prerequisites.
Treatment of ornithosis
Tetracycline prescribe 0.4-0.5 g 4 times a day
Until the 5-7th day of normal body temperature. With intolerance
Tetracycline, as well as in the treatment of children up to 10 years and pregnant women
Women prescribe erythromycin at 0.25 g 4 times a day for 5-10 days since the normalization of body temperature.
Prevention lies in the prevention and treatment of ornithosis
Poultry.
