Abstract
The article presents the results of a study of the etiological structure and differential diag-nostic signs of avian salmonellosis. When identifying bacteria isolated from 128 blood samples of chickens with the use of rapid test "Salmonella latex kit" established the dominance of cultures of the microorganisms Salmonella spp. - of 10.94% (14 samples); 10 strains (71,43%) were attributed to Salmonella gallinarum, 4 (of 28.57%) to Salmonella pullorum. The overall level of resistance of Salmonella to ampicillin - 57,58%; tetracycline - 60,61%; streptomycin - 66,67%; had to 57,58%; 60,61% and 66,67% are sensitivity to norfloxacin amounted to 69,70%, to ceftazidime - 78,79%, enrofloxacin - 57,58%, ciprofloxacin - 69,70% of the tested strains. At postmortem examination the most frequently detected signs of pericarditis, hemorrhagic pneumonia, aeroscout, catarrhal-hemorrhagic enteritis, perihepatitis, hyperplasia of the spleen. The most frequently detected signs of pericarditis, aeroscout, catarrhal-hemorrhagic gastroenterocolitis, perihepatitis, inflam-mation of the ovaries, hyperplasia of the spleen. Revealed signs of congestive hyperemia, macrophage reaction, hyperplasia and plasmocytomas of lymphocyte transformation, increase the permeability of microcirculatory vessels, lymphoid-cellular infil-tration of loose fibrous connective tissue, perivascular oedema, disseminated thrombosis, proliferation of lymphocytes from lymph nodes, spleen, liver, and pancreas. In violation of the porosity of the blood vessels of serous membranes of organs were observed extensive serous oedema, the output of the formed elements of blood and the loss of fibrinogen.
