DNA vaccines against cattle dermatitis

Treatment of nodular dermatitis of cattle using DNA vaccines is being investigated at TSU

David Agabalaev, a researcher from the Institute of Biology of TSU, has developed a new method of treating nodular dermatitis of cattle – using DNA vaccines. T-lymphocytes are stimulated by proteins cytokines.

According to the biologist, the advantages of such vaccination are obvious: for example, it will take only 9 days to treat a cow, and not 18, as with the use of currently available serums and antiviral agents.

According to the calculations of the author of the project, the cost of the DNA vaccine is 300 rubles (instead of 2100 rubles, which are spent on the treatment of the animal today).

"No DNA vaccine has been created for this type of virus," says David Agabalaev, "although the problem requires a quick solution: outbreaks of the disease were observed in Russia in 2015. Stavropol Krai, Kalmykia, Kabardino-Balkaria, Ingushetia remain at risk for the disease. Unfavorable regions for nodular dermatitis are also Dagestan, Chechnya, and North Ossetia. As for foreign countries, large economic losses from the disease are noted in Israel, India, Azerbaijan."

Nodular dermatitis is an infectious disease characterized by a steady increase in body temperature, damage to the lymphatic system, edema, formation of skin nodes, damage to the eyes and mucous membranes of the respiratory and digestive organs. The source of infection is sick animals.

Despite the fact that the mortality rate in nodular dermatitis of cattle does not exceed 10%, the economic damage is significant. The reasons for this are a decrease in dairy and meat productivity, the quality of raw leather, a violation of sexual cyclicity in cows, and the development of temporary sexual sterility in bulls.
