antibodies to histoplasma capsulatum in human and animal populations of southeastern minnesota. 19695765636
border disease in a flock of minnesota sheep.a flock problem affecting newborn lambs on a minnesota farm was investigated. the lambs had hairy fleece and rhythmic tremors, and were unthrifty. histologic examination revealed hypomyelinization of the cns and hypertrophy of primary follicles in the skin. a virus antigenically related to bovine viral diarrhea virus was isolated. serum neutralization showed that a large number of flock ewes had much higher titers to bovine viral diarrhea virus than did control animals.19826279553
lingual abscesses in suckling and weaned lambs.lingual abscesses were found in lambs from 2 midwestern flocks. lesions resulted in reluctance to feed, emaciation, and death. plant material was demonstrated at the center of abscesses in 1 flock. veterinarians should examine tongues carefully when investigating lamb mortalities.19846392266
epizootics of ovine abortion due to toxoplasma gondii in north central united states.toxoplasma-induced abortions were diagnosed in 14 flocks of sheep, 4 in minnesota, 2 in iowa, and 8 in south dakota, during the 1982-1983 lambing season. toxoplasma gondii was seen in histologic sections from 6 placentas and from brains of 2 lambs. toxoplasma antibody was found by dye test and agglutination test in thoracic fluid of 15 fetal lambs. lesions typical of toxoplasmosis were seen in fetal placentas from 26 ewes.19846725100
prevalence of antibodies to seven viruses in a flock of ewes in minnesota.blood samples were collected from a flock of healthy ewes at a university of minnesota research station. sera from these blood samples were tested for antibodies against 7 viruses, using 3 tests (eg, virus-neutralization test for bovine viral diarrhea virus, infectious bovine rhinotracheitis virus, bovine adenovirus type 3, and bovine respiratory syncytial virus; hemagglutination inhibition test for parainfluenza virus type 3; and agar-gel immunodiffusion test for lentivirus of ovine progressive ...19882837112
enzootic toxoplasmosis in sheep in north-central united states.of 1,564 serum samples from adult ewes from 33 farms in iowa, minnesota, south dakota, kansas, and nebraska where toxoplasmosis-induced ovine abortions had been diagnosed, 65.5% were found positive for toxoplasma gondii antibodies using the modified agglutination test. toxoplasma gondii antibody titers of ewes were: less than 64 (34.5%), 64 (14.9%), 256 (22.0%), 1,024 (14.5%), and greater than 4,096 (13.8%). thus, 28.3% of sheep had high titers (greater than 1,024) indicating recently acquired t ...19892795369
failure of sheep to respond to repeated inoculations with an alcelaphine herpesvirus-1-like virus, isolated from a case of malignant catarrhal fever in american cattle.the replication of an alcelaphine herpesvirus-1-like virus (707k), isolated from a clinical case of malignant catarrhal fever in american cattle, was studied in sheep. viraemia was not observed in any of the six sheep repeatedly inoculated with the 707k virus or in four steers susceptible to malignant catarrhal fever which were housed together with these sheep for one year. none of the four steers seroconverted and only two of the six inoculated sheep showed a negligible and short-lived seroconv ...19911759339
seasonal dynamics and variation among sheep in densities of the sheep biting louse, bovicola ovis.cyclic patterns and variations among sheep in numbers of bovicola ovis are described in polypay and columbia ewes that were initially infested with equal numbers of lice and penned indoors continuously for 2 years. bovicola ovis populations were censused at 3-4-week intervals at 69 body sites on each animal. in the second year of the study, the ewes were reinfested and half were mated. louse populations were monitored on the resulting lambs from birth until 25 weeks of age. strong seasonal cycle ...19989512991
pediatric lung transplantation and "lessons from green surgery.".during the past decade, lung transplantation has emerged as the definitive treatment for children with end-stage lung disease. pediatric transplantation presents unique challenges with respect to diagnostic indications, donor-recipient size disparities, perioperative management, and growth. lessons from the early development of cardiac surgery at the university of minnesota (green surgical service) provide a useful model for novel surgical challenges. since 1990, 25 lung transplantations have be ...199910505987
injuries among children and youth in farm households: regional rural injury study-i.the purpose of this effort was to identify the incidence and consequences of both farming and non-farming related injuries and the potential risk factors for farming related injuries among children and youth, aged 0-19 years, who lived in farm households in a large region of the united states.200111428558

prehospital rapid-sequence intubation: a pilot training program.to develop a training program enabling paramedics to use sedation and paralytic medications to facilitate endotracheal intubation in patients who otherwise could not be successfully intubated.200312710785
polymorphism and transcription at the p44-1/p44-18 genomic locus in anaplasma phagocytophilum strains from diverse geographic regions.a polymorphic multigene family (p44) of anaplasma phagocytophilum encodes the immunodominant 44-kda major outer membrane proteins. with p44-specific pcr and gene-specific probes, p44-1 was found in all human isolates from new york state but not in isolates from minnesota, whereas p44-18 and two other p44 species were found in isolates from both regions. we therefore sequenced the genomic locus corresponding to the p44-1/p44-18 tandem locus of a. phagocytophilum hz in 14 other geographically dive ...200415385454
rabies surveillance in the united states during 2007.summary: during 2007, 49 states and puerto rico reported 7,258 cases of rabies in animals and 1 case in a human to the cdc, representing a 4.6% increase from the 6,940 cases in animals and 3 cases in humans reported in 2006. approximately 93% of the cases were in wildlife, and 7% were in domestic animals. relative contributions by the major animal groups were as follows: 2,659 raccoons (36.6%), 1,973 bats (27.2%), 1,478 skunks (20.4%), 489 foxes (6.7%), 274 cats (3.8%), 93 dogs (1.3%), and 57 ca ...200818795848
