ues, and dispersion of specific granulomas. pathogenesis organs rich in reticuloendothelial tissue are the site of brucellosis replication. phagocytosis in neutrophils is incomplete. as a result of incomplete phagocytosis, phagocytes turn into a reservoir and replication site. pathogenesis the process by which the pathogen enters the bloodstream occurs repeatedly, caused by the particulars of the clinical presentation of acute brucellosis. multiple repetitions of brucellemia and toxemia leads to a change in the body’s reactivity and sensibilization, often hypersensibilization akin to a specific allergy. as a result of progressive allergization, there arises a background that gives rise to pathological changes in various tissues and organs due not only to specific agents, but also to non-specific ones. all types of allergic reactions are represented with brucellosis. the disease is characterized by polyallergy. initially the process is caused by infectious factors that eventually give way to autoallergic and paraallergic factors. pappas g et …

g up to 3 months: a. by completeness of clinical symptoms: - acute septic form; - septic-metastatic form. 3. sub-acute brucellosis lasting from 3 to 6 months. 4. chronic brucellosis lasting from 6 months to 2 years. 5. primary chronic brucellosis. 6. residual brucellosis (clinical presentation of sequelae of brucellosis history). by site of foci of infection in sub-acute and chronic brucellosis: - osteoarticular form neural form urogenital form visceral form combined form (combined damage to organs). depending on the degree of incapacitation, subacute and chronic brucellosis are divided into: - compensation phase (corresponds to the remission period without clinical signs of the disease); subcompensation phase (clinical presentation leading to reduced capacity); decompensation phase (most pronounced clinical presentation leading to incapacitation). clinical criteria 1. general infection syndrome: - relatively long satisfactorily tolerated fever; - chills of varying severity; - increased sweating; - overall weakness and malaise. 2. symptoms of focal …
