Antibiotics are frequently used in hospice care, despite limited data on safety and effectiveness in this patient population. We surveyed Oregon hospice programs on antibiotic policies and prescribing practices. Among 39 responding hospice programs, the median reported proportion of current census
During 1996 and 1997, the U.S. Fish and Wildlife Service conducted a study to determine the cause(s) of population decline and low survival of pronghorn antelope (Antilocapra americana) fawns on Hart Mountain National Antelope Refuge (HMNAR) located in southeastern Oregon (USA). As part of that
The authors conducted a retrospective hospital-based chart review of cases of hemolytic-uremic syndrome among children less than or equal to 18 years of age, hospitalized in Oregon during the four-year period from January 1979 to December 1982. Thirty children with hemolytic-uremic syndrome living
Bovine viral diarrhea virus (BVDV) isolates can either be cytopathogenic (cp) or noncytopathogenic (noncp). While both biotypes express the nonstructural protein NS2-3, generation of NS3 strictly correlates with the cp phenotype. The production of NS3 is usually caused by cp specific genome
Over a 2-year period, 296 episodes of disease involving 226 1-to-60-day-old calves were referred to the Caldwell Veterinary Teaching Center. Infectious disease agents were found in 96% of the cases. Salmonella spp were the most frequently isolated agents from dairy calves, whereas coronavirus was
In September 2014, a previously healthy Oregon woman in her 60s went to a hospital emergency department with malaise, dyspnea, vomiting, and diarrhea of 3-5 days' duration. She reported no recent travel, ill contacts, or dietary changes. Six days earlier, she had received a single dose of yellow
Cytopathogenicity of Bovine viral diarrhea virus (BVDV) is correlated with expression of the nonstructural protein NS3, which can be generated by processing of a fusion protein termed NS2-3. For the cytopathogenic (cp) BVDV strain Oregon, NS2-3 processing is based on a set of point mutations within
Chronic gastrointestinal illness of unknown etiology is a significant problem in the United States. Using a real-time LightCycler PCR assay we detected Blastocystis in nine patients from a metropolitan area of Corvallis, Oregon who presented with diarrhea, abdominal pain, fatigue, joint pain, skin
A live bovine viral diarrhea (BVDV) vaccine, marketed as a derivate of the Oregon C24V strain, was used between the end of the 1960s and the beginning of the 1990s in Central Europe. Since laboratory investigations of mucosal disease cases in vaccinated animals suggested recombinations between the
Epitopes recognized by nine monoclonal antibodies (mAbs) on the envelope protein, gp53, of two strains of bovine viral diarrhoea virus (NADL and Oregon C24V) were mapped by competitive binding assays and by the characterization and sequence analyses of mAb neutralization escape mutants. This defined
A disease broke out in calves in the Tokachi district of Hokkaido. It induced pyrexia, respiratory symptoms, diarrhea, bloody feces, leukopenia, and sometimes erosion of the oral mucous membrane and muzzle. Its morbidity rate was 90% and its fatality rate 50%. Bovine virus diarrhea (BVD) virus was
Diarrhea, erosions and ulcers of the oral mucosa, with conjunctival and nasal discharges, were observed in six calves inoculated with a mixture of two laboratory cytopathic reference strains of bovine viral diarrhea virus (BVDV)-Oregon C24 V and NADL. The clinical picture was accompanied by biphasic
Specific staining of antigen within bovine embryo kidney tissue culture cells, infected with either Oregon C24V or NADL-MD bovine viral diarrhea virus, was accomplished using fluorescein-conjugated swine anti-hog cholera or bovine antiviral diarrhea globulin. Also specific staining of antigen within
Examination of the C24V (Oregon) and MAC A (Ontario) strains of bovine viral diarrhea viruses have shown them to be ribonucleic acid containing viruses, with essential lipid and having compound helical symmetry with the diameter of the helix being in the neighbourhood of 180 A. Because of these
