| bot fly myiasis of the cottontail rabbit, sylvilagus floridanus mallurus in virginia with some biology of the parasite, cuterebra buccata. | twenty four percent of 2,643 cottontail rabbits (sylvilagus floridanus) collected in virginia from 1949-1975 showed evidence of cuterebra parasitism. occurrence was seasonal with greatest prevalence from july to november. some oryctolagus cuniculus, s. palustris and one s. transitionalis also showed cuterebra myiasis. juvenile rabbits had higher infection rates (28%) than did adult rabbits 14.5%, p less than .001). juveniles had greater numbers of larvae per host than adults, with means of 2.14 ... | 1978 | 633518 |
| natural transmission of keystone virus to sentinel rabbits on the delmarva peninsula. | domestic rabbits were exposed in the pocomoke cypress swamp from early may through october 1973, to act as sentinel indicators of keystone (key) virus transmission on the delaware-maryland-virginia (delmarva) peninsula. rabbits were bled weekly and their sera were tested for the presence of neutralizing antibody to both key and james-town canyon (jc) viruses. adult mosquito activity was monitored concurrently by cdc miniature light traps with dry ice. of 100 rabbits exposed, 20 rabbits acquired ... | 1978 | 717629 |
| arthritis in the prehistoric southeastern united states: biological and cultural variables. | recent research shows that a bacterial life form, erysipelothrix insidiosa, can produce rheumatoid arthritis in deer, swine, and dogs, and that a number of animals, including man, birds, and fish, may be infected by the organism. examination of the archaeological record suggests that both cultural and biological variables may be interrelated in the maintenance of some forms of arthritis over long periods of time in geographically disparate populations. re-examination of cherokee folk beliefs con ... | 1975 | 1098480 |
| an epizootic of cerebrospinal nematodiasis in cottontail rabbits. | a progressively debilitating neurologic syndrome characterized by torticollis, ataxia, circling, and abnormal posture was observed in 16 of approximately 60 cottontail rabbits (sylvilagus floridanus) captured in a 12-hectare portion of a woodlot in southwestern virginia. inflammatory and degenerative alterations in cerebellum and midbrain regions were characterized principally by malacia, perivascular cuffing, and gliosis. single ascaris columnaris larvae were found in the cerebellum of 2 rabbit ... | 1975 | 1176355 |

| 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 |
| orthotopic cardiac transplantation in a veterans administration hospital. | of 57 patients referred to the mcguire veterans administration medical center, richmond, va, for evaluation for cardiac transplantation, 18 received allografts. the overall graft survival rate was 67% from two to 24 months after transplantation. in 15 recipients receiving immunosuppression with rabbit anti-human thymocyte globulin, prednisone, and azathioprine, previous transfusion and hla-dr matching resulted in improved graft survival. in three patients receiving cyclosporin and prednisone, hy ... | 1984 | 6422905 |
| serologic evidence of jamestown canyon and keystone virus infection in vertebrates of the delmarva peninsula. | serological data accumulated during the past decade indicated that a variety of feral and domestic animals of the delaware-maryland-virginia (delmarva) peninsula were infected with jamestown canyon (jc) and/or keystone (key) viruses (bunyaviridae, california serogroup). neutralizing (n) antibody to jc virus was most prevalent in white-tailed deer, sika deer, cottontail rabbits and horses. key virus n antibody was detected most frequently in gray squirrels and domestic goats. n antibody indicativ ... | 1982 | 7149110 |
| host utilization and seasonal occurrence of dermacentor species (acari:ixodidae) in missouri, usa. | a total of 3,235 dermacentor variabilis (say) specimens were collected from birds, mammals, and by dragging vegetation, and 2,683 d. albipictus (packard) ticks were collected from deer from 1993 to 1996. peak seasonal occurrence of adult d. variabilis was from may through july with a precipitous decrease in august. nymphal d. variabilis populations peaked in june. peak activity of larvae was bimodal, with one activity peak during late summer (september) and a second peak in winter or early sprin ... | 2000 | 11201355 |
| same-day transfer of patients to the cardiac telemetry unit after surgery: the rapid after bypass back into telemetry (rabbit) program. | early data from this project suggest that the rabbit program fulfilled the process improvement goals of decreasing costs of cardiac surgery and maintaining high quality. decreased cost was achieved by decreasing time to extubation and decreasing length of stay in the icu and the total length of stay in the hospital. the cost savings were achieved without compromising the quality of care, which was assessed by measuring rates of readmission to the icu and to the hospital and by surveying patients ... | 2000 | 11873752 |

| ectoparasites and associated pathogens of free-roaming and captive animals in zoos of south carolina. | a survey of ectoparasites and their associated pathogens was conducted in two south carolina zoos, from 2004 to 2007. dead, wild birds and mammals, as well as captive animals examined during routine veterinary checks constituted the study populations. ectoparasites were tested for species of anaplasma, bartonella, coxiella burnetii, ehrlichia, rickettsia, and trypanosoma. forty-six species of ectoparasites were collected from 133 free-roaming and captive hosts and their associated nesting and be ... | 2009 | 18973443 |
| prevalence of igg antibodies to encephalitozoon cuniculi and toxoplasma gondii in cats with and without chronic kidney disease from virginia. | kidney disease is a common and serious condition in domestic cats. there are numerous causes of kidney disease including parasitic infection. encephalitozoon cuniculi is a microsporidian parasite that develops in the kidneys of rabbits and causes chronic renal disease. little has been reported concerning e. cuniculi in cats and no serological studies on this parasite in cats have been conducted in the united states to date. the present study explored the possibility that e. cuniculi is an unreco ... | 2010 | 21247702 |
| development of an nih consortium for preclinical assessment of cardioprotective therapies (caesar): a paradigm shift in studies of infarct size limitation. | an estimated 935 000 americans suffer a myocardial infarction every year; because their prognosis is determined by the size of the infarct, reducing infarct size is of paramount importance to alleviate morbidity and mortality. for 40 years, the national heart, lung, and blood institute (nhlbi) has invested enormous resources (at least several hundred million dollars) in preclinical studies aimed at developing infarct-sparing therapies, and several hundred (if not thousands) therapies have been c ... | 2011 | 21821536 |
| Hepatitis E virus in rabbits, Virginia, USA. | We identified hepatitis E virus (HEV) in rabbits in Virginia, USA. HEV RNA was detected in 14 (16%) of 85 serum samples and 13 (15%) of 85 fecal samples. Antibodies against HEV were detected in 31 (36%) of 85 serum samples. Sequence analyses showed that HEV from rabbits is closely related to genotype 3. | 2011 | 22099094 |
| carcass type affects local scavenger guilds more than habitat connectivity. | scavengers and decomposers provide an important ecosystem service by removing carrion from the environment. scavenging and decomposition are known to be temperature-dependent, but less is known about other factors that might affect carrion removal. we conducted an experiment in which we manipulated combinations of patch connectivity and carcass type, and measured responses by local scavenger guilds along with aspects of carcass depletion. we conducted twelve, 1-month trials in which five raccoon ... | 2016 | 26886299 |
