oculo-bubonic form of tularemia
Fig. 2. Oculo-bubonic form of tularemia.

Bubonic form accompanied by the development of regional lymphadenitis (Fig. 1). Bubny there are single and multiple, one - and two-sided, with value up to chicken eggs and more. Localization buboes depends on the place of the introduction of the pathogen (armpit, the neck, groin, and so on). Bubny can be established, pussy to soften, to sklerozirovanie as a result of proliferation of connective tissue. The resolution of Bubnov is slow, in waves. The duration of the disease is delayed up to 3-4 months. In the presence of inflammatory changes of the skin in the place of the entrance gate occurs ulcerative-bubonic form of tularemia. The skin may develop (consistently) stain, papules, vesicles, pustules, and ulcers.
Oculo-bubonic form occurs with conjunctivitis, submandibular, cervical bubo (Fig. 2). Possible loss of vision.
Angina-bubonic form is accompanied by redness and grayish-white-sided raids on the tonsils. Further possible necrosis and ulceration. Bow and tongue swollen and giperemiei. Marked pain and difficulty swallowing.
For abdominal forms typical nausea and severe abdominal pain due to the development of mesenteric Bubnov that can simulate the so-called acute abdomen.
Pulmonary form (primary) is characterized by primary inflammation in the lungs. With the defeat of only upper respiratory tract develops bronchietasis option, which is characterized by diffuse bronchitis and dry cough without cold. Ends with recovery within 8-12 days. When tularemia focal pneumonia tapped dry and wet traiterous wheezing. She described as heavy, creeping, relapsing, nekrotizirutee. Different sluggish and backbreaking over, lasts up to 2 months. and more. There is a tendency to merge separate foci on the type of equity pneumonia. Confirmed by x-ray data. Possible complications such as bronchiectasis, gangrene light, dry and exudative pleurisy.
Secondary (metastatic) pneumonia is a complication of bubonic and other forms of tularemia. Proceeds easier primary, but long - term, with acute and recurrent.
Generalized form (primary septic). Typical weakness, myalgia, loss of appetite, undulating fever within 2-4 weeks or more, in severe cases, delusions. Often there are skin rash: roseola, papules, vesicles, petechiae, followed by peeling.
