| swine tuberculosis in south dakota. | mycobacteria were isolated from 195 of 200 lesions in lymph nodes identified as granulomatous by meat inspectors at 4 abattoirs in south dakota. mycobacterium avium serotypes 1 and 2 accounted for 89% of the isolants. mycobacteria were isolated more frequently from lesions than acid-fast bacilli were observed on microscopic examination (p less than 0.001). the frequency with which mycobacteria was isolated was similar to the occurrence of granulomatous lesions. the numbers of the various kinds o ... | 1975 | 1150507 |
| nutrient database for distiller's dried grains with solubles produced from new ethanol plants in minnesota and south dakota. | a study was conducted to evaluate the nutrient content and variability of distiller's dried grains with solubles (ddgs) originating from new (less than 5 yr old) ethanol plants in minnesota and south dakota. ten plants (8 mn, 2 sd) participated in the study, submitting a total of 118 samples. samples were collected every 2 mo from ten ethanol plants in the minnesota-south dakota (mnsd) region from 1997 to 1999 and were analyzed for amino acid levels, dm, cp, crude fiber, crude fat, ash, adf, ndf ... | 2002 | 12413086 |
| geographic variations, cloning, and functional analyses of the venom acidic phospholipases a2 of crotalus viridis viridis. | geographic venom samples of crotalus viridis viridis were obtained from south dakota, wyoming, colorado, oklahoma, texas, new mexico, and arizona. from these samples, the phospholipases a(2) (pla(2)s) were purified and their n-terminal sequences, precise masses, and in vitro enzymatic activities were determined. we purified two to four distinct acidic pla(2)s from each sample; some of them displayed different inhibition specificities toward mammalian platelets. one of the acidic pla(2)s induced ... | 2003 | 12623078 |
| seroprevalence of and risk factors for toxoplasma gondii in the us swine herd using sera collected during the national animal health monitoring survey (swine 2006). | the united states department of agriculture (usda) initiated the national animal health monitoring system (nahms) in 1983 to collect, analyse and disseminate data on animal health, management and productivity in us domestic livestock populations, including swine. the programme includes an on-farm serological sampling component which can be used to monitor seroprevalence of various pathogens, including toxoplasma gondii. the purpose of this study was to determine the seroprevalence of t. gondii i ... | 2010 | 19744304 |
| a family of intracardiac ultrasound imaging devices designed for guidance of electrophysiology ablation procedures. | our bioengineering research partnership grant, -high frequency ultrasound arrays for cardiac imaging", including the individuals cited at the end of this paper - douglas n. stephens (uc davis), matthew o'donnell (uw seattle), kai thomenius (ge global research), aaron m. dentinger (ge global research), douglas wildes (ge global research), peter chen (st. jude medical), k. kirk shung (university of southern california), jonathan m. cannata (university of southern california), butrus (pierre) t. kh ... | 2009 | 19963529 |

| heterogeneity in nsp2 of european-like porcine reproductive and respiratory syndrome viruses isolated in the united states. | recently, isolates of porcine reproductive and respiratory syndrome virus (prrsv) that possess nucleotide sequences similar to european isolates have been reported in united states herds. the origin, diversity and prevalence of european-like north american prrsv isolates in the u.s. remain unknown. nucleotide sequence analysis of the 12kb orf1 of a north american isolate, sdprrs 01-08 (01-08), showed 93.7% identity with lelystad virus (lv), the prototypic european isolate, but only 58% identity ... | 2004 | 15019241 |
| a pre-pandemic outbreak of triple-reassortant swine influenza virus infection among university students, south dakota, 2008. | after identifying a student with triple-reassortant swine influenza virus (siv) infection and pig exposure at a livestock event, we investigated whether others were infected and if human-to-human transmission occurred. | 2011 | 21917888 |
| close relationship between the 2009 h1n1 virus and south dakota aiv strains. | although previous publications suggest the 2009 pandemic influenza a (h1n1) virus was reassorted from swine viruses of north america and eurasia, the immediate ancestry still remains elusive due to the big evolutionary distance between the 2009 h1n1 virus and the previously isolated strains. since the unveiling of the 2009 h1n1 influenza, great deal of interest has been drawn to influenza, consequently a large number of influenza virus sequences have been deposited into the public sequence datab ... | 2011 | 21331891 |
