Summary. Due to the emergence of favorable conditions for numerous passages with a high concentration of livestock, often not observing basic sanitary and hygienic norms and rules by livestock owners, the microbiological background of the operated premises, microbial contamination of the mucous membranes of open cavities of animals significantly changes. Under these conditions, among the assembled livestock, the spectrum of pathogenic microorganisms may include various viruses, bacteria, mycoplasmas and chlamydia, which inevitably leads to their associative interaction and the appearance of mixed infections. Often, in the complex pathology of cattle, the main role is played by conditionally pathogenic (factorial) microflora, in particular, Escherichia spp. This work describes pathomorphological changes in the associative course of infectious rhinotracheitis -pustular vulvovaginitis and colibacteriosis in the large horned cattle. During the autopsy of dead and stillborn calves from heifers with this association, 15 main pathoanatomical diagnoses corresponding to changes in organs and tissues were established: serous or catarrhal conjunctivitis; acute serous or catarrhal rhinitis, laryngitis, tracheitis; necrotic ulcerative laryngitis, tracheitis; hemorrhagic diathesis; acute serous lymphadenitis; atelectasis of the lungs and edema of interstitial connective tissue; acute serous splenitis (septic spleen); granular and fatty degeneration, hemorrhages in the liver; acute serous nephritis; hyperemia and hemorrhages under the epi- and endocardium; acute alterative myocarditis; acute catarrhal or hemorrhagic gastroenterocolitis; hemorrhagic or acute catarrhal with striated hemorrhages proctitis; acute catarrhal vulvovaginitis and balanoposthitis; hyperemia and swelling of the brain and meninges; adhesive serous placentitis.
Keywords: parasitocenosis, associative diseases, conditionally pathogenic microflora, clinical and morphological forms of the disease, pathomorphological changes, viral and bacterial association, infectious rhinotracheitis, colibacteriosis, pathoanatomic autopsy, pathoanatomic diagnoses.
