Chlamydia psittaci

NetworkSection III Parrot chrysanthemumParrot chrysanthemum C. psittaci's primary host is poultry, so another disease name (Ornithosis) has been proposed to show that the source of the disease is not limited to parrot birds, but many birds, including poultry and wild birds. Second, the host is a mammal other than humans, who are infected only after they come into contact with the animal. Whether humans have primary parrot fever infection is still under debate. But human parrot fever as a poultry industry occupational disease has been recognized by the medical community.humans can become infected after being exposed to parrot chrysogens. However, the incubation period is often difficult to determine, because contact with birds or mammals is sometimes very short, sometimes regular, it is generally believed that between 6 to 15 days, the incubation period of individual cases can be as long as nearly 40 days. The disease is acute, the patient has cold, sore throat, headache, discomfort, body temperature of about 38 degrees C, if the pulse rate, it means poor head prognosis. The initial symptoms are very much like influenza. A small number of cases can develop gradually, with only varying degrees of headache within the first week, much like the common cold. With the development of the disease, patients restless, insomnia, and even delirium, serious people appear in a coma. Symptoms of systemic poisoning, acute renal failure, pancreatitis, rapid death, separation from the lungs to parrot chlamydia. However, the typical case clinical manifestations are atypical pneumonia, dry cough, a small amount of mucus, there is a clear rust color, individual main complaint of chest pain. White blood cells are slightly lower. Chyroid toxin-induced toxicemia can make patients nausea, vomiting, and even jaundice, less urine. Severe cases can affect the cardiovascular and nervous system, manifested as myocarditis, endocarditis, meningitis and encephalitis and other symptoms, can be detected in myocarditis patients in the myophageal macrophages. There are usually cases of heart damage at the same time there is pneumonia, the fatality rate is also high. Patients with severe infections mostly die at 2 to 3 weeks of onset. Before
antibiotics
unheard of, the epidemic death rate of the disease was 20%. It has now fallen below 1 per cent and is mostly elderly and young. Clinically, according to the symptoms, there is a history of bird droppings exposure can be initially diagnosed. However, given the wide variation in clinical conditions, laboratory assistance is required to provide a clear diagnosis.Parrot chlamydia is easy to grow in chicken embryo yolk sacs and HeLa cells, monkey renal cells
culture
and can infect mice with pneumonia, periaryitis or encephalitis and die.parrot chrysophylline also produces a red blood cell coagulant that collects red blood cells from mice and chickens. This coagulant is a lecithin complex whose effects can be inhibited by specific
antibody
and Ca.pathogen isolation can take the patient's blood or sputum. Sputum liquid should be treated with streptomycin. Injected into the mouse cavity and chicken embryo ostogenesic sac, the vaccinated animals often die within 7 to 10 days. After the cesarean examination, spleen, lung, liver and other smears were colored to see if there were chrysanthromats and narcolepsy. When the results are positive,
serum
be performed.specific antibody elevation can often be detected after serological tests. Complementary binding antibodies have a long maintenance time in the body and can be tested with double serum specimens in the early and late stages of the disease.if the late serum is 4 times higher than the early serum antibody titration or more, it is of diagnostic significance. In addition, blood clotting inhibition tests can be carried out.
