[epidemiologic study of lyme disease in asturias].	the aim of this study was to confirm the sierra del sueve (asturias) as an endemic area for lyme's disease and determine the seroprevalence of this disease in inhabitants of this and other zones of asturias.	1993	8260513
levels of pcdds and pcdfs in farm cow's milk located near potential contaminant sources in asturias (spain). comparison with levels found in control, rural farms and commercial pasteurized cow's milks.	cows milk samples from 12 dairy farms in spain and 23 samples of pasteurised cows milk were analysed for pcdd/f. farms located in rural areas without specific dioxin sources (background levels) ranged from 1.3 to 2.47 pg teq/g fat basis. these values were slightly lower than those found in milk from the vicinity of potential dioxin emission sources (waste incinerator, chemical and metallurgical industry) and similar to milk near paper industry. the waste incinerator seems to be the emission sour ...	1997	9375353
seroprevalence of neospora caninum and abortion in dairy cows in northern spain.	the seroprevalence of neospora caninum infection was estimated from a sample of 889 cattle from 43 dairy herds in three counties in the asturias region of spain. the true prevalence of infection was estimated to be 30.6 per cent (95 per cent confidence interval (ci) 27.6 to 33.6). seropositivity was associated with abortion during the previous year (odds ratio (or)=3.31, p<0.001) and was slightly higher among purchased cattle (37.6 per cent), than among cattle raised on the farm (29.1 per cent) ...	1999	10460027
serological prevalence to six leptospiral serovars in cattle in asturias (northern spain).	the prevalence of antibody to six serovars of leptospira interrogans in cattle in asturias (northern spain) was determined by the microscopic agglutination test (mat). using 50% agglutination or lysis at a dilution of 1:10 or more as the criteria for seropositivity, 371 of 3578 (10.36%) animals were found to react with one serovar. the most commonly detected serovars were pomona (5.59%) and grippotyphosa (2.37%), whilst serovar hardjo (0.75%), icterohaemorrhagiae (0.64%), poi (0.64%) and autumna ...	2000	10982084
mercury concentrations in cattle from nw spain.	mercury is a toxic metal that is released into the environment as a result of various industrial and agricultural processes. it can be accumulated by domestic animals and so contaminate human foodstuffs. to date, there is no information on mercury residues in livestock in spain and the aim of the present study was to quantify the concentrations of mercury in cattle in two of the major regions in north-west spain, galicia (a largely rural region) and asturias, which is characterised by heavy indu ...	2003	12526901
large-scale spatial variation in mercury concentrations in cattle in nw spain.	mercury (hg) is a highly toxic environmental contaminant and man-made emissions account for between a quarter and a third of total atmospheric levels. point discharges, particularly coal-burning power stations, are major sources of atmospheric hg and can result in marked spatial variation in mercury deposition and subsequent uptake by biota. the aims of this study were to quantify the extent to which major point and diffuse sources of atmospheric hg emissions affected accumulation of hg by biota ...	2003	12810311
[bovine brucellosis in the provinces of asturias and leon. (its public health and economic importance)].		1963	14091062
effects of moderate pollution on toxic and trace metal levels in calves from a polluted area of northern spain.	this study evaluated the contribution of anthropogenic pollution to toxic metal residues (cd, pb and as) in cattle in an industrialized area of asturias (northern spain), and investigated possible implications of toxic metal exposure for metabolism of essential metal elements (cu, zn, fe, mn). samples of liver, kidney, muscle and blood from animals aged 9-12 months were obtained from an industrialized area (78 calves) and from a rural area (92 calves). samples were acid-digested, and levels of m ...	2004	15788195
copper, zinc, iron, and manganese accumulation in cattle from asturias (northern spain).	monitoring levels of mineral concentrations in animal tissues is important for assessing the effect of contamination on animal health and safety of animal origin products in human nutrition. this study evaluated the levels of certain trace elements (copper, zinc, iron, and manganese) in cattle from an industrial and mining region in the north of spain (asturias). samples of 312 animals aged 9-12 mo were collected from the whole region and analyzed after acid digestion using atomic absorption spe ...	2006	16444003
organochlorine pesticide and polychlorinated biphenyl in calves from north-west spain.	the aim of the present study was to assess the levels of organic pollutants in cattle from the nw of spain. the livers of 101 animals from two regions (galicia and asturias) were analysed for seven organochlorine pesticides (hcb, alpha-hcch, u-hcch, heod, ddt, tde) and 34 pcbs congeners (8, 18, 28, 29, 31, 52, 77, 101, 105, 114, 118, 123, 126, 128, 138, 141, 149, 153, 156, 157, 167, 169, 170, 171, 180, 183, 187, 189, 194, 199, 201, 205, 206 and 209). the influence of different factors (type of f ...	2008	18825299
cadmium and lead in bovine milk in the mining area of the caudal river (spain).	the levels of cadmium and lead in 36 raw bovine milk samples were analysed. these samples come from seven farms with a semi-extensive grazing system and were collected between the autumn of 2007 and the winter of 2008. all the farms were located in asturias (spain), a zone of great industrial and mining activity in the proximities of the caudal river. the samples were collected in sterile precleaned polypropylene tubes and frozen until the analysis. after a lyophilization process, the samples we ...	2011	21800067
