Pathomorphological changes in the tissues of the cardiovascular system in fetuses and newborn calves in chlamydia

Chlamydiosis is a contagious disease of humans, animals and birds, whose pathogens are recognized as microorganisms with a unique development cycle, which are obligate intracellular parasites. The presence of a chlamydial infection is the polytropism of the pathogen. During the life of the activity, chlamydia adapted to the cells of various organs and tissues, including the tissues of the cardiovascular system. In our studies, the pathological and anatomical picture in aborted fetuses was characterized by the expansion of the heart cavities, the presence of small-spot, petechial and large-patch hemorrhages under the epicardium and adventitia of large arteries. Microscopically recorded pathology from the cells of the vascular bed. Endothelial cells of small vessels had an enlarged nucleus. Large vessels marked the widespread desquamation of the endothelium, due to which their lumen was significantly narrowed. In the vascular wall there was a widespread swelling due to which the muscle layer was thickened...
