Summary. Data on frequently registered sporadic acute infectious disease of large horned cattle – malignant catarrhal fever – are presented in the article. Characteristic feature of the epizootic disease is the absence of contagiousness among the livestock of large horned cattle. Most frequently disease is registered in private farms, where cattle is kept and grazed together with sheep and goats. Clinical signs of the disease (hypersalivation, nasal discharge, suppression, high temperature, feed refusal, lesions on oral mucous membrane, etc.) were reminiscent of foot-and-mouth disease in vaccinated against FMD cattle, so it led to mistakes in clinical diagnostics. Pathological changes were not recorded in sheep and goats. Particular difficulties arise with the clinical diagnostics of the disease in the buffer zone of FMD, i.e. in the area of systematic vaccination against foot-and-mouth disease. It was found that in some cases malignant catarrhal fever occurred in large horned cattle simultaneously at babesiosis, infectious bovine rhinotracheitis and viral diarrhea, as well as at chronic poisoning. In addition, in some cases, the disease was preceded by a planned prophylactic vaccination against FMD, pasteurellosis and other infections. All this suggests the necessity of the account of malignant catarrhal fever in the clinical diagnosis of foot-and-mouth disease.
Keywords: large horned cattle, sheep, herpesvirus, malignant catarrhal fever, foot-and-mouth disease, viral diarrhea, infectious bovine rhinotracheitis, salivation, inflammation, fever, mucous membranes, oral and nasal cavities, conjunctivitis, animal mortality.
