Structure of geo nematodosis on the territory of Ulyanovsk region
The purpose of work was the investigation of the structure of geo nematodosis Sus scrofa domestica and its agroclimatic confinement. During achieve this goal, diversity of species of helminth fauna of Sus scrofa domestica were examined, the dominant species are identified, especialities of epizootic manifestations of geo nematodosis Sus scrofa domestica in different agroclimatic zones of Ulyanovsk region were characterized. The work was conducted in the period 2011-2013 Traditional methods of helminthological dissect investigations were used. For three years 2715 samples were treated. Extensive morbidity in the territory of districts, which were expressed in percent, were evaluated. Spatial distribution of pig farms was conducted using a geographic information system MapInfo. Research of geo nematodosis of 4 agroclimatic zones of the Ulyanovsk region have shown that the dominant by geo helminthiases circulate in the population of pigs of all zones, but extensiveness of invasions varies considerably. The southern zone is the most favourable to the circulation of esophagostomiasis, trihotsefaleza, and strongyloidosis, but is unfavorable for ascariasis. Extensity of ascariasis invasion in this area is minimal. These zonal patterns are repeated and large populations of pig farms and in small populations farms.
