NATURAL FOCUS FORMATION FOR RABIES IN THE TRANSBORDER LAND BETWEEN RUSSIA AND MONGOLIA

Abstract

The paper presents the data on the analysis of rabies manifestation characteristics and the role of wild animals in the formation of natural focus of the infection in the transborder land of Russia (Buryatia) and Mongolia. In Mongolia, rabies was registered in 15 out of 22 aimaks. The highest indexes of animal morbidity recorded in 2010 were revealed in Bulgan and Khovsgol aimaks. In 2011, 58 animals got sick that was 57.7 % as little as in the year 2010. In 2010, the main part to maintain the natural focus of the infection was played by the fox (56.1 %) and the wolf (33.3 %), and two cases of the disease were revealed in the bat. The share of livestock made up 45.8 and 55.2 % in 2010 and 2011, respectively. In 2011, rabies diseased animals- wild and domestic- were recorded in Buryatia’s Zakamensk area bordering Mongolia, 25 km north off the border line. A mere 32 samples were examined in the republic research and production laboratory; of them, 15 results (46.9 %) were positive. The causative agent was detected in 7 foxes, 1 badger, 1 wolf, which constituted 60.0 % of the total positive results.
