survey of bioavailable selenium in sweden with the moose (alces alces l.) as monitoring animal.liver tissues were collected from moose (alces alces l.) from the regular hunting seasons of 1981 and 1982. the material (from about 4300 animals) was stored at -20 degrees c at the national veterinary institute (sva). from this material, 2080 specimens from 12 counties representing 14 regions were analyzed for selenium. the counties included were norrbotten, västernorrland (northern region), uppsala, kopparberg, gävleborg, jämtland (central region), north and south kalmar (eastern region), hall ...19958560217
bartonella spp. seroprevalence in healthy swedish blood donors.serum samples were collected from healthy blood donors in 5 regions in sweden in 1999, i.e. from the local blood centres (collecting facilities) in boden, jönköping, lund, skövde, and uppsala. in total, 498 serum samples (63% males, 37% females) were received and tested by immunofluorescence assay for antibodies against b. elizabethae, b. grahamii, b. henselae (houston-1), b. henselae (marseille), b. quintana, and b. vinsonii subsp. vinsonii. an overall bartonella spp. seroprevalence of 16.1% wa ...200516191889
listeria monocytogenes in faeces from clinically healthy dairy cows in sweden.faecal samples from 102 clinically healthy dairy cows, representing 34 farms in the swedish province of uppsala, were analysed for the presence of listeria spp. using an enrichment procedure. listeria monocytogenes was isolated from six (6%) and l. innocua from 2 (2%) cows. from each of the 6 samples positive for l. monocytogenes, 5 isolates were further characterised by restriction enzyme analysis using the 3 enzymes apa i, sma i, and asc i, followed by pulsed-field gel electrophoresis. three o ...200010965567
biospheric 129i concentrations in the pre-nuclear and nuclear age.in order to detect characteristic regional differences or temporal changes of 129i concentrations in the biosphere, thyroids from humans, grazing livestock, and herbivorous wildlife species (reindeer and roedeer) were collected in various areas of the world which are not affected by reprocessing plants. for reasons of comparison, all samples were analyzed for their 129i:127i atom ratios. human and bovine thyroids taken from the 10th region in southern chile (39 degrees-41 degrees south) indicate ...19938244695
prehibernation diet and reproductive condition of female anopheles messeae in sweden.1. blood and sugar feeding in the mosquito anopheles messeae falleroni were investigated near uppsala, sweden, from 1981 to 1985, with emphasis on prehibernation diet. 2. fructose, indicating plant feeding, was present in females of all ovarian stages, from april to october, and contributed to fat body development in non-gonoactive females before hibernation. 3. an.messeae males and females (inseminated and uninseminated) were observed feeding on floral nectaries of the plants achillea millefoli ...19911768915
intramammary infections with different non-aureus staphylococci in dairy cows.subclinical mastitis causes an increase in milk somatic cell count (scc) and can lead to reduced milk production and early culling. in many countries, non-aureus staphylococci (nas) is the most common bacterial finding in subclinical mastitis of dairy cows. new methodology makes it possible to identify nas species, but knowledge about the epidemiology is limited. the objective of this project was to improve advisory services for mastitis control by investigating associations between nas and scc, ...201829174143
a limited number of y chromosome lineages is present in north american holsteins.holsteins are the most numerous dairy cattle breed in north america and the breed has undergone intensive selection for improving milk production and conformation. theoretically, this intensive selection could lead to a reduction of the effective population size and reduced genetic diversity. the objective of this study was to investigate the effective population size of the holstein y chromosome and the effects of limited y chromosome lineages on male reproduction and the future of the breed. p ...201525660742
