a poxvirus of primates. i. growth of the virus in vitro and comparison with other poxviruses.	a primate poxvirus (orteca) isolated from a skin lesion in a rhesus monkey (macaca mulatta) was studied along with four known poxviruses: vaccinia, monkeypox, swinepox, and yaba. it grows in established lines of monkey kidney cells at a rate intermediate between that of vaccinia and monkeypox and that of swinepox and yaba. the cytopathic effects produced by orteca virus resemble those produced by swinepox virus, although, unlike swinepox, it cannot be propagated in porcine cells. neither can ort ...	1970	18605415
myxomatosis in domestic rabbits in oregon.	an epizootic of myxomatosis involved 26 rabbitries in western oregon. major clinical signs were inflammation and edema of the eyelids, conjunctiva, and anogenital area. mortality ranged from 20 to 50%. on histologic examination, intracytoplasmic inclusion bodies were readily apparent in the epithelial cells of the conjunctiva. lymphoid depletion of the spleen was also a common finding.	1977	914688
generalized viral illness caused by an intermediate strain of adenovirus (21/h21 + 35).	ten isolates of an antigenically intermediate strain of adenovirus were recovered from eight persons who presented febrile upper respiratory illness, pneumonia, or multisystem disease between november 1976 and august 1978. six isolates were recovered from four members of an extended family in which the other nine members all had serologic evidence of infection; the other four isolates were epidemiologically unrelated. the isolates were placed in hemagglutination group ib on the basis of results ...	1980	6245153
antigenic analysis of giardia lamblia from afghanistan, puerto rico, ecuador, and oregon.	the trophozoite antigens of giardia lamblia to which host humoral and cellular immune responses are directed have not been identified. therefore, we initiated studies to characterize these antigens in strains of g. lamblia from afghanistan, oregon, ecuador, and puerto rico. by polyacrylamide gel electrophoresis, the electrophoretic mobility patterns of proteins of the four strains were similar; molecular weights of protein bands ranged between 12,000 and 140,000. the antigens which reacted with ...	1982	7085076
development and application of a dot-elisa test for the detection of serum antibodies to fasciola hepatica antigens in llamas.	a microenzyme-linked immunosorbent assay (dot-elisa) was developed to detect serum antibodies against fasciola hepatica antigens in llamas. sera from five f. hepatica-infected and 11 non-infected llamas were used in initial test development. nitrocellulose filter disks containing f. hepatica excretory-secretory product were placed in 96-well microtiter plates, washed, blocked with tween-20, then incubated with four-fold serial dilutions of llama sera. after incubation with rabbit anti-llama igg ...	1995	7676604
population genetic structure of ixodes pacificus (acari:ixodidae) using allozymes.	genetic analysis of the population structure of the western blacklegged tick, ixodes pacificus cooley & kohls, was conducted using allozymes. this vector tick transmits the lyme disease spirochete, borrelia burgdorferi johnson, schmid, hyde, steigerwalt & brenner, in the far-western united states. it ranges from british columbia to baja california and disjunct populations are present in oregon, nevada, utah, and arizona. host-seeking adult ticks were collected from vegetation across the range of ...	1997	9220679
sterilisation without surgery.	in the us, the most popular permanent method of birth control among women aged 30 years and older is tubal ligation. however, the need to be hospitalized for tubal ligation surgery and its attendant costs mean that many women worldwide cannot afford to have the procedure performed. considerable unmet demand therefore exists for an alternative method of female sterilization which requires neither hospitalization nor abdominal incisions. an experimental, nonsurgical method of sterilization has ...	1997	12179208
characterization of a sarcocystis neurona isolate (sn6) from a naturally infected horse from oregon.	an isolate of sarcocystis neurona (sn6) was obtained from the spinal cord of a horse from oregon with neurologic signs. the parasite was isolated in cultures of bovine monocytes and equine spleen cells. the parasite divided by endopolygeny and completed at least one asexual cycle in cell cultures in three days. two gamma interferon knockout mice inoculated with cell culture-derived merozoites became ill 35 d later and s. neurona schizonts and merozoites were found in encephalitic lesions. the pa ...	1999	10519218
fetal ventricular mass determination on three-dimensional echocardiography: studies in normal fetuses and validation experiments.	estimation of ventricular volume and mass is important for baseline and serial evaluation of fetuses with normal or abnormal hearts. direct measurement of chamber wall volumes and mass can be made without geometric assumptions by 3d fetal echocardiography. our goals were to determine the feasibility of using fast nongated 3d echocardiography for fetal volumetric and mass assessments, to validate the accuracy of the ultrasound system and the measurement technique, and if satisfactory, to develop ...	2004	15326076
a pathogenic new species of eimeria from the pygmy rabbit, brachylagus idahoensis, in washington and oregon, with description of the sporulated oocyst and intestinal endogenous stages.	in january 2003, fecal samples from 13 live pygmy rabbits, brachylagus idahoensis (merriam, 1891), were collected at the oregon zoo in portland, oregon, and sent to the university of new mexico (unm), albuquerque, new mexico, to be examined for coccidia. in july 2004, 14 more fecal samples were collected and sent to unm, 6 from some of the same rabbits and 8 from 16 other rabbits (4 were pooled samples from siblings). in addition, tissue sections from 3 dead rabbits (2 from the oregon zoo, 1 fro ...	2005	16108556
nationwide outbreak of red eye syndrome associated with transfusion of leukocyte-reduced red blood cell units.	to characterize red eye reactions occurring within 24 hours after receipt of units of leukocyte-reduced red blood cells, determine their etiology, and investigate their potential link to transfusion.	2006	17080369
homer wheelon, m.d., physiologist, artist, and poet: origins of the tailpieces in journals of the american physiological society.	since 1953, illustrations have been inserted as "tailpieces" at the ends of articles in the american journal of physiology and the journal of applied physiology. the drawings were made by homer wheelon, a member of the american physiological society from 1919 until his death in 1960. forty-five years after his death, wheelon is unknown, but he contributed 32 publications to the medical literature and trained j. earl thomas, an important 20th century gastrointestinal physiologist. wheelon was bor ...	2006	16887919
