| apteragia pursglovei sp. n. (trichostrongyloidea: trichostrongylidae) from the white-tailed deer, odocoileus virginianus. | two species of apteragia were found in white-tailed deer (odocoileus virginianus) from 152 counties in 13 southeastern states. specimens previously reported as skrjabinagia odocoilei were reidentified as belonging to 2 similar species of the genus apteragia, a. odocoilei, and a. pursglovei sp. n. apteragia pursglovei sp. n. is differentiated primarily by the length, conformation, and degree of sclerotization of the spicules. of the 824 deer, a. odocoilei occurred in 76.5%, a. pursglovei in 13.8% ... | 1979 | 448613 |

| increasing density and borrelia burgdorferi infection of deer-infesting ixodes dammini (acari: ixodidae) in maryland. | a statewide survey of ixodes dammini spielman was done in november 1991 as a follow-up to a study in 1989. in total, 3,434 adult ticks were collected from 922 hunter-killed white-tailed deer processed at 22 check stations (1 per county in 22 of 23 counties in the state). significantly more male than female ticks were collected. tick infestation was significantly heavier on male than female deer. the pattern of tick distribution was similar to that in 1989, with low prevalence (percentage tick-in ... | 1993 | 8254631 |
| serologic evidence of a natural infection of white-tailed deer with the agent of human granulocytic ehrlichiosis in wisconsin and maryland. | white-tailed deer participate in the maintenance of the ixodes tick life cycle and are reservoirs for some tick-borne infectious agents. deer may be useful sentinels for tick-transmitted agents, such as ehrlichiae. in order to determine whether white-tailed deer are markers of natural transmission or are reservoirs for the human granulocytic ehrlichiosis (hge) agent, we performed indirect immunofluorescent-antibody (ifa) tests and immunoblotting with the hge agent and ehrlichia chaffeensis on se ... | 1998 | 9801331 |
