| isolation of streptococcus suis from swine in nebraska. | streptococcus suis was isolated from swine with localized and diffuse infections. the isolates (n = 121) were unable to grow in broth containing 6.5% nacl. their abilities to hydrolyze esculin were variable, as were their fermentative reactions in lactose, trehalose, raffinose, and inulin. sorbitol was not attacked by any strain. serologic reactions were obtained between the isolates and coagglutination reagents prepared from commercially available antisera to streptococcal groups d, r, or s. | 1984 | 6490489 |

| 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 case-crossover study of occupational laceration injuries in pork processing: methods and preliminary findings. | meatpacking remains a hazardous and largely unexamined industry. despite prevention efforts, laceration injuries, among others, remain high. we estimated the magnitude of associations between transient exposures such as equipment malfunction, performing an unusual work task, rushing, and occurrence of laceration injuries. | 2010 | 20837650 |
| first record of pseudorabies in feral swine in nebraska. | in 2007, two new populations of feral swine were discovered in nance and valley counties, nebraska, usa. necropsies and serologic testing was done on two individuals from the nance county herd. results indicated that a lactating sow had positive antibodies for pseudorabies virus (prv). investigations conducted by nebraska game and parks commission law enforcement division confirmed that the infected individual was transported illegally to nebraska, usa, from texas, usa. all domestic swine herds ... | 2009 | 19617504 |
| the history of hesperopithecus: the human-ape link that turned out to be a pig. | nebraska man was a fossil discovery that was regarded by several leading experts as important in understanding evolutionary history. the only evidence for this anthropod was a single tooth (which turned out to be a pigs' tooth). the discovery and controversy surrounding the nebraska man (hesperopithecus haroldcookii hominoidea) fossil find and its importance in history are reviewed. its supporters' writings reveal the critical role that preconceptions played in interpreting the limited evidence. ... | 2006 | 17115373 |
| mobile in vivo biopsy and camera robot. | a mobile in vivo biopsy robot has been developed to perform a biopsy from within the abdominal cavity while being remotely controlled. this robot provides a platform for effectively sampling tissue. the robot has been used in vivo in a porcine model to biopsy portions of the liver and mucosa layer of the bowel. after reaching the specified location, the grasper was actuated to biopsy the tissue of interest. the biopsy specimens were gathered from the grasper after robot retraction from the abdom ... | 2006 | 16404097 |
| nutrient balance on nebraska livestock confinement systems. | managing the environmental risk associated with livestock production is a significant challenge. nitrogen and phosphorus are commonly implicated as the sources of ground and surface water quality problems associated with livestock production. the degree of imbalance between these nutrient inputs and the managed nutrient outputs for a livestock operation defines the magnitude of potential environmental risk and provides insight as to the underlying causes of these challenges. a nitrogen and phosp ... | 1999 | 15526781 |
| applying functional genomics research to the study of pig reproduction. | functional genomics is an experimental approach that incorporates genome-wide or system-wide experimentation, expanding the scope of biological investigation from studying single genes to studying potentially all genes at once in a systematic manner. this technology is highly appealing because of its high throughput and relatively low cost. furthermore, analysis of gene expression using microarrays is likely to be more biologically relevant than the conventional paradigm of reductionism, because ... | 2001 | 11980196 |
| prevalence of antibodies to hepatitis e virus in veterinarians working with swine and in normal blood donors in the united states and other countries. | hepatitis e virus (hev) is endemic in many developing and some industrialized countries. it has been hypothesized that animals may be the source of infection. the recent identification of swine hev in u.s. pigs and the demonstration of its ability to infect across species have lent credence to this hypothesis. to assess the potential risk of zoonotic hev infection, we tested a total of 468 veterinarians working with swine (including 389 u.s. swine veterinarians) and 400 normal u.s. blood donors ... | 2002 | 11773103 |

| evidence for quantitative trait loci affecting ovulation rate in pigs. | fifty-five microsatellite markers were scored in an f2 population of pigs (n = 114 females) developed at the university of nebraska. the population was produced by crossing a line previously selected for 10 generations using an index of ovulation rate and embryonal survival and a line selected at random. the lines were from a common base population and differed by 6.7 ovulations and 3.1 fetuses at 50 d of gestation. ovulation rate and number of fully formed and mummified pigs were recorded for e ... | 1997 | 9250508 |
| serotypic differentiation of rotaviruses in field samples from diarrheic pigs by using nucleic acid probes specific for porcine vp4 and human and porcine vp7 genes. | of 216 fecal and intestinal samples collected from nursing or weaned diarrheic pigs in the united states and canada, 57 were identified as group a rotavirus positive by rna electrophoresis and silver staining. fifty-seven and 52 rotavirus-positive samples were analyzed by hybridization with gottfried and osu pcr-derived gene 9 and 4 probes, respectively. only 17 samples were identified with either homologous vp4 (p)- or vp7 (g)-coding genes or both. one rotavirus identified as g4 and p7 was simi ... | 1994 | 8150940 |
| serological and genotypic characterization of group a rotavirus reassortants from diarrheic calves born to dams vaccinated against rotavirus. | two strains of bovine rotavirus (brv), designated strain nebraska scottsbluff-1 (ns-1) and ns-2, were isolated from 2 neighboring cow-calf beef cattle ranches where dams had been vaccinated with a commercial vaccine containing group a brv strain neonatal calf diarrhea virus (ncdv)-lincoln (p1:g6). northern blot hybridizations using whole genomic rna probes indicated that strains ns-1 and ns-2 had identical group a rna electrophoretic patterns and were homologous at all gene segments. strain ns-1 ... | 1994 | 7886929 |

| genetic and phenotypic parameters estimated from nebraska specific-pathogen-free swine field records. | records collected during 1971 through 1979 from 101,606 hogs raised in 18 nebraska specific pathogen free herds were analyzed. traits considered were backfat at 100 kg (bf), weight at 140 d of age (wt) and, in some analyses, number of live pigs/litter at birth (nba). the phenotypic correlation of bf and wt, averaged across herds, was -.07. the correlations between bf and nba and between wt and nba were .04 and -.05, respectively. average phenotypic standard deviations for bf, wt and nba were 2.6 ... | 1983 | 6227597 |
| serologic survey for bordetella bronchiseptica in nebraska specific-pathogen-free pigs. | the frequency of bordetella bronchiseptica infection in nebraska specific-pathogen-free (spf) pigs was determined by serologic and bacteriologic cultural analysis. serum samples from non-spf herds were tested for comparison. a total of 1,282 of 1,397 (92%) of the spf pigs tested had antibody to b bronchiseptica; 37 of 220 (17%) were culture-positive, and 67 of 4125 (1.6%) were considered suspicious for atrophic rhinitis during slaughter inspection. a higher percentage of the non-spf pigs had tit ... | 1983 | 6223547 |
