Psittacosis: diagnosis and treatment

Content

Ornithosis (psittacosis) - Infectious Diseases
disease characterized by symptoms of intoxication, lung lesions and
tendency to protracted course with exacerbations.

Pathogen ornithosis refers to chlamydia. It is resistant to low temperature and drying.

source
the causative agent of infection is poultry. The largest epidemiological
important are pets and pet birds, parrots, pigeons, wild
waterfowl, in which psittacosis is usually asymptomatic.
However, the deterioration of the content of poultry feed their lack
may show signs of the disease. Birds refuse to feed,
inactive, they observed diarrhea, mucus from the nose. Disease
It lasts 8-9 days and ends with the death of the bird.

The main ways
pathogen transmission - airborne dust and airborne. Human
infected by inhalation of dust contaminated with feces and nasal mucus
sick birds. Ill mostly workers of poultry farms, hunters
game birds, owners of pet birds.



What are the symptoms of psittacosis

incubatory
period lasts within 5-30, usually 8-12 days. In some patients
initially marked malaise, nausea, pain in the joints. Usually
disease develops acutely with chills, fever;
marked headache, muscle pain, joint pain, back pain, throat,
severe weakness, insomnia, dry cough, redness of the face and throat,
redness of the sclera and conjunctiva. There are dry, scratchy throat,
the voice becomes hoarse, rough, there is a feeling of tightness in the chest,
rawness in the sternum. In the most typical form of pneumonic
disease initially dry cough, phlegm in the future, sometimes
bloody. At 4-5 days of illness appear physical signs
pneumonia, shortness of breath, sometimes cyanosis. Chance of pleurisy. Sometimes the disease
It takes a chronic course with relapses.



Diagnosis and treatment of psittacosis

Diagnosis
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.

Psittacosis: diagnosis and treatment
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
immunofluorescence.

Treatment
is carried out in a hospital. Apply tetracycline antibiotics or
rifampicin, inflammatory and antiallergic agents.

Forecast
when time begun treatment is usually favorable. In some patients
long-term (several years), marked fatigue, sluggish
inflammation in the airways and lungs.

prevention
It consists in carrying out the animal health and public health
events. The former include veterinary and sanitary supervision
poultry farms, zoos, at poultry plants; early
identification of psittacosis in poultry and pet birds, holding
preventive, current and final disinfection. The trading network
from farms, disadvantaged ornithosis, gutted carcasses of birds in the form of
after heat treatment are sent to an industrial process. eggs
and subjected to heat treatment. Feathers burned. Treatment
birds must be carried out in respirators and safety glasses while
should strictly follow the rules of personal hygiene (wash hands before eating,
after work).

The epidemic outbreak and conduct current
final disinfection. For persons in contact with patients
birds, establish medical surveillance for 2 weeks
daily thermometry, give an allergic diagnostic tests and
reaction of binding complement to ornitoznoy antigen. With the aim of
preventing persons have been in contact with sick birds, should be
taking the antibiotic tetracycline for 2-3 days.
They have been ill are under medical supervision for at least 1 year and
removed from the account when there is no recurrence of the disease.
