| potential role of deer tick virus in powassan encephalitis cases in lyme disease-endemic areas of new york, u.s.a. | powassan virus, a member of the tick-borne encephalitis group of flaviviruses, encompasses 2 lineages with separate enzootic cycles. the prototype lineage of powassan virus (powv) is principally maintained between ixodes cookei ticks and the groundhog (marmota momax) or striped skunk (mephitis mephitis), whereas the deer tick virus (dtv) lineage is believed to be maintained between ixodes scapularis ticks and the white-footed mouse (peromyscus leucopus). we report 14 cases of powassan encephalit ... | 2013 | 24274334 |
| the groundhog tick ixodes cookei (acari: ixodidae): a poor potential vector of lyme borreliosis. | evidence for infection with the spirochete, borrelia burgdorferi, was sought in ixodes cookei and in groundhogs (marmota monax) in southern ontario, canada, and ticks fed on experimentally inoculated hosts were examined for the spirochete. borrelia burgdorferi was not detected by immunofluorescent examination of 110 larval, nymphal or adult i. cookei collected from the environment, or taken from humans and other animals. three groundhogs inoculated with b. burgdorferi developed titers of 1:20 to ... | 1993 | 8355343 |
| spotted fever group rickettsiae or borrelia burgdorferi in ixodes cookei (ixodidae) in connecticut. | immatures and females of ixodes cookei, a hard-bodied tick, were collected from woodchucks and other mammals in the northeastern united states and examined for spotted fever group rickettsiae and borrelia burgdorferi. of the 93 nymphs analyzed by a hemolymph test, 4 (4.3%) harbored rickettsiae. six (15%) of 40 females were also infected. all infected ticks were collected from woodchucks in connecticut. indirect fluorescent antibody staining of midgut tissues from 128 nymphs revealed b. burgdorfe ... | 1991 | 1885748 |
