Climate variations and salmonellosis in northwest Russia: a time-series analysis.

Associations between monthly counts of all laboratory-confirmed cases of salmonellosis in Arkhangelsk, northern Russia, from 1992 to 2008 and climatic variables with lags 0-2 were studied by three different models. We observed a linear association between the number of cases of salmonellosis and mean monthly temperature with a lag of 1 month across the whole range of temperatures. An increase of 1 °C was associated with a 2·04% [95% confidence interval (CI) 0·25-3·84], 1·84% (95% CI 0·06-3·63) and 2·32% (95% CI 0·38-4·27) increase in different models.

The impact of climate change on the expansion of Ixodes persulcatus habitat and the incidence of tick-borne encephalitis in the north of European Russia.

Background: The increase in tick-borne encephalitis (TBE) incidence is observed in recent decades in a number of subarctic countries. The reasons of it are widely discussed in scientific publications. The objective of this study was to understand if the climate change in Arkhangelsk Oblast (AO) situated in the north of European subarctic zone of Russia has real impact on the northward expansion of Ixodid ticks and stipulates the increase in TBE incidence.

[Population health risk from chemical air pollutants in a city with developed pulp and paper industry].

to assess an effect of chemical contaminants contained in emissions of pulp and paper mill on prevalence respiratory and cardiovascular diseases in population of Novodvinsk. The average annual concentrations of chemicals of concern were calculated by modeling. A prevalence of population was studied by using of the primary medical documentation in sex among children from 0 to 17 and adults from 65 and older Hazard index (HIi) was used to assess the non-cancer health effects.

Detection and identification of bacterial agents in Ixodes persulcatus Schulze ticks from the north western region of Russia.

Ixodes persulcatus Schultze ticks are traditionally associated with transmission of Lyme disease, babesiosis, and tick-borne encephalitis. Here we compared the prevalence of infection with Borrelia burgdorferi, and rickettsial and ehrlichial agents in I. persulcatus ticks collected in different locations of the North Western administrative region of Russia.
