Abstract
The forecast of epizootic situation on main animal helminthiases in the Russian Federation in the year 2016 is presented. Regular monitoring of epizootic situation on main animal helminthiases allow to conclude that the development of epizootic process at helminthiasis is affected by environmental factors: condition of pastures, water basins, weather and climate, especially in current pasture season, which requires the antiparasitic treatments.
Keywords: forecast, epizootic situation, helminthiases.
Monitoring of epizootic situation on main pasture helminthiases in farm animals shows that the pasture season in 2016 will be unfavorable in relation to parasitic infestation due to ecological events: light precipitations, small amount of snow, quick snow melting.
This allows to forecast the occurrence of helminthiasis and fascioliasis, within the common time limits but with some time delay, in European part of Russia, Moscow region and contiguous areas Bryansk, Kaluga, Tver’, Smolensk, Ryazan’, Kursk and other regions, especially in northwestern region of RF.
With respect to fascioliasis, a stable ill-being was forecasted not only in farm ruminants but also in wildlife: deer, elks, wild boars, especially in lower part of the northwestern region of Russia, Northern Caucasus and irrigation areas.
In the Far East, in underflooding zones in 2014-2015 the acute outbreaks of fascioliasis, opisthorchiasis (clonorchiasis), paramphystomatosis, orientobilharziosis, and other trematodoses including metagonimosis transmitted through fish and mollusks, are possible.
According to the information of VIGIS and other scientific research institutes, in the southern part of Western Siberia, Yakutia, Tuva and in the Far East in zones of extensive underflooding and moisturizing as well as in the period of snowmelt floods, in 2016 the epizootic situation on fascioliasis and other trematodoses will deteriorate.
A trend for increase of eurytrematosis infection in cattle (South of Siberia, Tuva, Altai and the Far East as well as orientobilharziosis and paramphystomatosis in unfavorable regions of Khabarovsk Krai and the Far East still persists due to massive infestation of acridoid grasshoppers.
Abundant precipitation in summer season in European part of Russia, in farm regions of Altai and Siberia may lead to dictyocaulosis, mulleriosis and protostrongylosis in ruminants, horses and wild ruminants.
The increase of Strongylata populations and pasture contamination creates a potential threat for outbreaks of strongylatosis and death of animals with intensive invasion.
In different climate zones of Russia, the deterioration of epizootic situation on echinococcosis, taeniosis, coenurosis is to be expected; the infection rate with echinococcus and taenia of dogs from Nothern Caucausus (Dagestan) and contiguous areas is 100 % which will cause the increase of zoonotic infection in ruminants.
More than 140–190 thousands of animals were slaughtered due to echinococcosis.
Observations of epizootic situation on main animal helminthiases in 1990-2015 in Russian Federation allow to conclude that generally the epizootic process of main helminthiases is affected by ecological components: condition of pastures, water basins, weather and climate, especially in current pasture season; therefore, it is required to conduct antiparasitic treatments.
To eliminate the losses caused by a.m. parasites to the agriculture, it is necessary to carry out the full complex of antiparasitic measures.
