| ectoparasitic and phoretic arthropods of virginia opossums (didelphis virginiana) in central tennessee. | thirteen species of ectoparasitic (12) or phoretic (1) arthropods were collected from 26 adult virginia opossums, didelphis virginiana, live-trapped from april through september 1987 in davidson county, tennessee. the cat flea ctenocephalides felis and the american dog tick dermacentor variabilis were the predominant species with respect to mean intensity and prevalence. the macronyssid mite ornithonyssus wernecki and the atopomelid mite didelphilichus serrifer, both specific parasites of this h ... | 1990 | 2380870 |

| ticks (acari: ixodidae) infesting medium-sized wild mammals in southwestern tennessee. | seven species of ixodid ticks (n = 2,661) were found on medium-sized wild mammals (n = 295) during a 13-mo study in shelby county, tennessee. the seven tick species collected were dermacentor variabilis (say), amblyomma americanum (l.), rhipicephalus sanguineus (latreille), ixodes texanus (banks), i. cookei (packard), i. scapularis (say), and haemaphysalis leporispalustris (packard). the raccoon had the greatest tick species diversity in all of the aforementioned ticks except h. leporispalustris ... | 1993 | 8254637 |
| spotted fever group rickettsia in dermacentor variabilis (acari: ixodidae) infesting raccoons (carnivora: procyonidae) and opossums (marsupialia: didelphimorphidae) in tennessee. | spotted fever group rickettsia were present in 13 of 1,171 (1.1%) of adult dermacentor variabilis say removed from raccoons (procyon lotor l.) and virginia opossums (didelphis virginiana kerr) in western tennessee. spotted fever group rickettsia were detected by amplification of a 617-bp segment of the citrate synthase gene by polymerase chain reaction. | 2001 | 11476343 |
| prevalence of ehrlichia chaffeensis and ehrlichia ewingii in ticks from tennessee. | human ehrlichiosis is the second most common tick-borne disease reported in tennessee after rocky mountain spotted fever. two closely related ehrlichiae, ehrlichia chaffeensis and ehrlichia ewingii, are both causative agents of human disease and are transmitted by amblyomma americanum, the lone star tick. prevalence rates and distribution patterns of these pathogens among ticks in tennessee are currently unknown. to understand prevalence and exposure risk of ehrlichia spp., we tested 616 ticks ( ... | 2010 | 19877819 |
| host associations of dermacentor, amblyomma, and ixodes (acari: ixodidae) ticks in tennessee. | from april 2007 to september 2008, 1,793 adult and nymphal ixodid ticks were collected from 49 counties in tennessee. six species were identified, including dermacentor variabilis (say), amblyomma americanum (l.), ixodes texanus (banks), ixodes cookei packard, ixodes scapularis (say), and amblyomma maculatum koch, from 13 medium- to large-sized mammalian hosts and dragging through vegetation. raccoons were the most common vertebrate source (198 captures), accounting for 60% of ticks collected. d ... | 2010 | 20496589 |
| absence of rickettsia rickettsii and occurrence of other spotted fever group rickettsiae in ticks from tennessee. | rocky mountain spotted fever (rmsf) is the most common tick-borne illness in tennessee. little is known about the occurrence of r. rickettsii, the causative agent, in ticks in tennessee. to better understand the prevalence and distribution of rickettsial agents in ticks, we tested 1,265 amblyomma, dermacentor, and ixodes adult and nymphal ticks. additionally, we tested 231 amblyomma americanum larvae. ticks were collected from 49 counties from humans, wild animals, domestic canines, and flannel ... | 2010 | 20810834 |
| patterns of infestation by adult dermacentor variabilis (acari: ixodidae) in a mark-recapture study of raccoons (mammalia: carnivora) and virginia opossums (mammalia: didelphimorphia) in tennessee. | a mark-recapture study of raccoons (procyon lotor l.) and virginia opossums (didelphis virginiana kerr) was conducted from february 1991 through april 1994 to determine host interactions with adult dermacentor variabilis say. we captured 1,293 raccoons and virginia opossums during the 3-yr study (140 individual raccoons and 160 individual virginia opossums) with 1,895 adult d. variabilis collected. raccoons had a significantly higher mean intensity and higher prevalence of adult ticks than virgi ... | 1999 | 10337094 |
| interspecific differences between small mammals as hosts of immature dermacentor variabilis (acari: ixodidae) and a model for detection of high risk areas of rocky mountain spotted fever. | fourteen species of small mammals were captured from july 1990 through august 1991 in tennessee, from which 1,217 immature dermacentor variabilis and 1 ixodes dentatus were collected. mammal species were given scores of importance (ts) as hosts to immature d. variabilis based on mean intensity and prevalence. the rice rat ranked the highest, with a ts = 5, followed by the golden mouse ts = 4, white-footed mouse ts = 3, pine vole ts = 2, cotton rat ts = 1, with the norway rat, house mouse, and sh ... | 1996 | 8885876 |

| parasitic and phoretic arthropods of sylvatic and commensal white-footed mice (peromyscus leucopus) in central tennessee, with notes on lyme disease. | sixteen species of parasitic or phoretic arthropods were collected from 56 white-footed mice, peromyscus leucopus, live-trapped in central tennessee from april through november 1987. arthropod infestation was compared for mice taken from sylvatic (woodland) versus commensal (household) habitats. three species were recorded from hosts in both habitats: the sucking louse hoplopleura hesperomydis, the flea epitedia wenmanni, and the laelapid mite androlaelaps casalis. twelve of the 13 remaining art ... | 1991 | 2010854 |
