The incubation period is likely to depend on the dose, ranging from 1 to 3 weeks.
Diagnostic tests. Y. enterocolitica ° and Y. pseudotuberculosis can be allocated from the faeces, swabs from the pharynx, bryzheechnyh limfouzlov, peritoneal fluid or blood, a Y. enterocolitica also from synovial fluid, bile, urine, cerebrospinal fluid, sputum and wounds. Because the laboratory identification of pathogens from stool requires special techniques, laboratory should be informed that the suspected infections caused by Yersinia. Crops chairs are usually positive during the first 2 weeks of illness, regardless of expression gastrointestinal manifestations. The infection can be confirmed by demonstration of growth titer of serum agglutinin after infection, but those tests are conducted only in special laboratories. Cross-reaction of these antibodies to Brucella, Vibrio, Escherichia coli, Salmonella and strains enterobaktery lead to false positive results. In patients with thyroid diseases constantly increased titer of antibodies to Y. enterocolitica can be called antigenic similarity with the membrane cause thyroid epithelial cells.
Treatment. Y. enterocolitica and Y. pseudotuberculosis sensitive to aminoglicoside, tsefotaksimu and some other new tsefalosporinom tetracycline (which should not be given to children up to age 9), chloramphenicol and trimetoprimsulfametaksazolu. Patients with septicemia, or with the localization of infection than in the gastrointestinal tract should be treated with antibiotics. Patients with enterokolitami or bryzheechnym adenitom not set advantage antibiotic therapy.
The isolation of hospitalized patients. For patients with enterokolitom shows intestinal precautions throughout the disease.
The control measures. Investigation of epidemic diseases in poultry and animals.
