NODULAR DERMATITIS VIRUS DISEASE Nodular dermatitis of cattle (in Latin dermatitis nodularis bovum, in English it is called limpy skin disease) is of viral origin and is characterized by short-term fever, damage to the skin, lymphatic system, mucous membrane, formation of nodules and necrosis in subcutaneous tissues. Spreading. The disease was first discovered in 1929 in Northern Rhodesia (located in Africa), and its clinical signs were described in 1931 by R. MacDonald in Zambia. Later, the disease was found in most countries of South Africa, as well as in Madagascar in 1954. According to the observations of P.C. Lefevre and others, during the last decades, the disease spread in most countries of the African continent, and at the same time it was recorded in the north-western states of India, R.M. Sharma shows. Economic damage. Mortality due to the disease is not higher than 10%. However, according to the conclusion of many researchers, the decrease in milk and meat production, the decrease in the quality of hide and skin products, the violation of the sexual cycle in cows, and temporary sexual activity in breeding bulls lead to a significant increase in economic damage. D. R. Navathe (1978), R. M. Sharma (1962) and others note that this infection costs India 50 million rupees annually.NODULAR DERMATITIS VIRUS DISEASE Nodular dermatitis of cattle (in Latin dermatitis nodularis bovum, in English it is called limpy skin disease) is of viral origin and is characterized by short-term fever, damage to the skin, lymphatic system, mucous membrane, formation of nodules and necrosis in subcutaneous tissues.
