Serum analysis was performed during October 2015 to April 2016 to ascertain the prevalence of bluetongue (BT) virus infection among sheep population in Odisha. Samples were collected randomly from apparently healthy sheep from 10 different agro-climatic zones of Odisha. Serum samples were screened for BT virus (BTV) antibodies using indirect enzyme linked immunosorbent assay (i-ELISA) at Divisi...
BACKGROUND A previous survey on allergens used by Mexican allergists in their skin prick test (SPT) panel showed wide variation. Humidity varies in different zones of Mexico. This might lead to differences in natural exposure and allergic sensitisation throughout the country. We aim to describe the SPT sensitivity patterns in the different climatic zones in Mexico and to show the usefulness of ...
The effect of climatic forcing on population synchrony and genetic structuring of the Canadian lynx.
The abundance of Canadian lynx follows 10-year density fluctuations across the Canadian subcontinent. These cyclic fluctuations have earlier been shown to be geographically structured into three climatic regions: the Atlantic, Continental, and Pacific zones. Recent genetic evidence revealed an essentially similar spatial structuring. Introducing a new population model, the "climate forcing of e...
The aim of this study was to evaluate the features of rheumatoid arthritis (RA) as well as other health problems and treatment necessities in various climatic and geographic zones of Uzbekistan. The data on 2013 patients with a confirmed diagnosis of RA were collected retrospectively. The results showed that the Khorezm and Surkhandarya regions dominated by indicators of disease activity and se...
The temporal and spatial vegetation dynamics is highly dependent on many different environmental and biophysical factors. Among these, climate is one of the most important factors that influence the growth and condition of vegetation. Of the abiotic factors affecting the geographic distribution of vegetation type, climate is probably the most important. Ecological research has traditionally aim...
In the present study effect of feeding area specific mineral mixture on the serum mineral status of cattle in different agro climatic zones (plateau, plain and hills) of Chhattisgarh state was studied. The soil and fodder mineral status of different zones were analyzed. Macro minerals were below desired level in soil of hill region followed by plateau and plain whereas Mg level in soils of diff...
Background: Changing the climatic pattern can lead to major changes in the geographical distribution of infectious diseases. The aim of this study was to investigate the effect of climate change on the favorable bio-climatological zone for leishmaniasis sand-fly living which is a vector of Leishmania in Iran. Materials and Methods: Data of the climatic factors affecting the biology of sandflies...
BACKGROUND Dermatophytosis, and particularly the subtype tinea capitis, is common among African children; however, the risk factors associated with this condition are poorly understood. To describe the epidemiology of dermatophytosis in distinct eco-climatic zones, three cross-sectional surveys were conducted in public primary schools located in the Sahelian, Sudanian and Sudano-Guinean eco-cli...
