| 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 |
| 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 |

| 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 |
| host associations and seasonal occurrence of haemaphysalis leporispalustris, ixodes brunneus, i. cookei, i. dentatus, and i. texanus (acari: ixodidae) in southeastern missouri. | hemaphysalis leporispalustris (packard), ixodes brunneus koch, ixodes cookei packard, ixodes dentatus marx, and ixodes texanus banks were collected during a 3-yr study of pathogen-tick-host interactions in southeastern missouri. h. leporispalustris was collected from the eastern cottontail rabbit, northern bobwhite, and carolina wren, and it was active all year. i. brunneus was collected by drag and from passerine birds during december, march, and april. i. cookei was collected from raccoons and ... | 2003 | 12597662 |
| 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 |
