Summary. Foot-and-mouth disease - acute highly contagious viral disease of cloven-hoofed domestic and wild animals, which in the modern classification of FAO/OIE refers to cross-border group of infections, i.e. diseases that have great economic importance for trade and food security. Epidemiological role of different types of cloven-hoofed animals as a source of FMD virus is unequal. Large horned cattle is extremely sensitive to respiratory infection. Clinical signs of foot-and-mouth disease are weak in sheep and goats, but animals actively excrete virus. Many sources present information on the registration of sheep and goats, clinical signs of foot-and-mouth disease with an experimental vesicular lesions in the mouth. This article presents the results of a survey of foot-and-mouth foci, clinical examination of infected animals and revealed pathological changes. Main clinical feature, allowing to suspect foot-and-mouth disease is lameness in most animals in the herd. Mass death of newborn animals is registered during lambing. Aphthous lesions on the udder are marked in lactating sheep and goats. Also characteristic clinical signs of foot-and-mouth disease are found mostly in the skin of inter-digital space. During clinical diagnosis it is necessary to exclude contagious pustular dermatitis (contagious ecthyma) of sheep and goats. All this indicates necessity of improvement of qualification of veterinary experts on the problem of foot and mouth disease and other vesicular diseases and epidemiological characteristics, clinical and postmortem diagnosis of these infections.

Keywords: sheep, goats, cross-border infection, foot-and-mouth disease, contagious pustular dermatitis, necrobacteriosis, vesicular lesions, aphthae, lameness, interdigital space.
