Microscopic changes in the organs of broiler chickens with Ornithobacterium rhinotra-cheale infection

Nowadays ornithobacteriosis is widespread among industrial poultry in Ukraine and the world. The disease leads to significant economic losses. large variation serotypes of bacteria complicates treatment disease. study microscopic changes that occur organs during will help better understand pathogenesis development. Ornithobacteriosis was diagnosed clinically sick broiler chickens by bacteriological studies using Maldi Tof mass-spectrometry. As a result antibiotic sensitivity test, pathogen found be sensitive doxycycline, tilmicosin, rifampicin, cefazolin, amoxiclav benzylpenicillin. Histological internal – trachea, lungs, heart, kidneys, liver spleen were carried out. It with spontaneous chickens, most expressive respiratory lungs trachea are characterized decrease lumen parabronchials due edema their walls infiltration lymphocytes, absence epithelium on surface parabronchials, narrowing air capillaries parabronchial complexes, hemorrhages parenchyma vasodilatation lung vessels overflow blood cells, around destruction part tracheal mucosa epithelial its submucosa, expansion mucous membrane cells. In there uniform diffuse number lymphocytes lymphoid follicles; kidneys stroma vessels, uneven glomeruli one renal corpuscles another, granular degeneration convoluted straight tubules kidneys; edema, hemorrhage, violation hepatic lobules’ structure, veins, hepatocytes or destruction; heart myocardial interstitium, muscle fibers’ dystrophy, fragmentation fibers as rupture. research ORT infected lead understanding mechanism pathological at level, which facilitate development more effective methods prevention
