Гепаральні патології за туберкульозу фазанів: патоморфологічний аналіз

Abstract

Наведені результати патоморфологічного дослідження печінки фазанів, які загинули за спонтанного туберкульозу. В окремих випадках завершення туберкульозних некрозів печінки поєднувалося із регенераційними процесами. За асоціації туберкульозних пошкоджень із жировою дистрофією чи протозоозними гепатитами спостерігалися тотальні та субтотальні деструктивні зміни.

The aim of this study was to establish the character of pathomorphologic changes in a liver of pheasants with spontaneous tuberculosis. Troupes of 3 pheasantsat different age with diagnosis "tuberculosis of bird" were object of research. Materials and methods of the researches. The work was made on the base of department of pathoanatomy and section of KhSZA. The methods of pathoanatomical section of bird dead bodies, pathogistologic researches of samples of bird liver, method of Ceel-Nelsen for the exposure of causative agent of tuberculosis of bird in the samples-imprints of liver were used. Result of the research. The signs of tuberculosis in 3 samples were revealed. Red microorganisms that have a shape of stick that placed individually or in pairs were revealed in samples which were coloured by Nelsen. Index est hat character for tuberculosis of birds, were found in all individuals during macroscopic research of liver. The results of pathohystologic researches of liver samples confirmed they tubercular specificity. Different combination of pathology of liver established in all individuals. Classification of this changes was made. In one case (miliar and submiliar kind of tuberculosis of peasant liver), bird death was as a resalt of destruction of vessels periportal zone of liver. On the other hand, tuberculosis change were different by stage of severity and influences on total state of organism. For example during large-focal form of tuberculs take place destruction all structures of liver. In this bird were diagnosted Eimeriosis and Histomonosis during they life. Also there were pattern of sclerotisation in area without damage. In case of hepatolipidosis, tuberculos damage were minimal and we classificate them as complicated pathology. The scale of indexes that important for differential diagnosis of bird tuberculosis was made on the basis pathomorphologic damage of liver. The classification of this changes and diagnostic scale have been made on the basis of macroscopic and pathomorphologic research of liver pathology. In occasional cases completion of liver tubercular necrosis of the feathery game combined with regenerative processes. Posttubercular complication from previous diagnostics of disease which can be used during macroscopic evaluation were revealed. It is potentially possible to determine the bird in high-risk group in relation to tuberculosis: granulosums of different structure, dug up walls of vessels, thrombosis, regeneration, sclerotization for registrations of the indicated signs of hepatic pathologies. The described descriptions of tuberculosis of birditis important to take in to account for the veterinary inspection of products of birdor at sectional research with the aim of the timely diagnostic of this nosology.
