| spirochetes in ticks and antibodies to borrelia burgdorferi in white-tailed deer from connecticut, new york state, and north carolina. | ticks were screened for spirochetes and serum samples from white-tailed deer (odocoileus virginianus) were assayed for antibodies to borrelia burgdorferi during 1983-1984. using fluorescein isothiocyanate-labeled rabbit antibodies produced to b. burgdorferi, the etiologic agent of lyme disease, spirochetes were detected in ixodes dammini (10.5% of 1,193) and dermacentor albipictus (0.6% of 157) adults from connecticut, i. dammini nymphs (49.1% of 108) and adults (64.7% of 99) from armonk, new yo ... | 1986 | 3520030 |
| comparison of rates of infection by the lyme disease spirochete in selected populations of ixodes dammini and amblyomma americanum (acari: ixodidae). | at a major endemic focus in new jersey, 50% of 290 adult ixodes dammini collected in the fall of 1984 were infected with the lyme disease spirochete (borrelia burgdorferi), which was statistically higher than the rate found in the 202 adult ticks (39.6%) examined during the spring. neither sex nor site of collection within the focus significantly affected the infection rate. the observed infection rates were similar to those reported in endemic areas of new york and connecticut. borrelia burgdor ... | 1986 | 3577494 |
| antibodies to spotted fever-group rickettsiae in dogs and prevalence of infected ticks in southern connecticut. | blood samples and ticks were obtained from dogs to assess canine exposure to spotted fever-group (sfg) rickettsiae during 1978-1980 in southern connecticut. of the 1,576 dog sera screened by microimmunofluorescence. 174 (11.0%) contained specific antibodies at titers greater than or equal to 1:64 against rickettsia montana (n = 34), r rickettsii (n = 31), r rhipicephali (n = 19), or the unclassified 369-c rickettsia (n = 90). end points greater than or equal to 1:8,192 to r rickettsii and to r r ... | 1982 | 6803626 |
| hemocytic rickettsia-like organisms in ticks: serologic reactivity with antisera to ehrlichiae and detection of dna of agent of human granulocytic ehrlichiosis by pcr. | ixodid ticks were collected from connecticut, massachusetts, missouri, pennsylvania, rhode island, and british columbia (canada) during 1991 to 1994 to determine the prevalence of infection with hemocytic (blood cell), rickettsia-like organisms. hemolymph obtained from these ticks was analyzed by direct and indirect fluorescent antibody (fa) staining methods with dog, horse, or human sera containing antibodies to ehrlichia canis, ehrlichia equi, or rickettsia rickettsii. of the 693 nymphal and a ... | 1995 | 8567911 |
| detection of ehrlichia chaffeensis dna in amblyomma americanum ticks in connecticut and rhode island. | ehrlichia chaffeensis, the causative agent of human monocytic ehrlichiosis, is transmitted by amblyomma americanum ticks, which are most abundant in the southern united states. because serologic evidence suggests that residents of connecticut are exposed to e. chaffeensis, a. americanum ticks were collected in connecticut and rhode island for pcr analysis to detect e. chaffeensis dna. eight of 106 (7.6%) a. americanum ticks from connecticut and 6 of 52 (11.5%) from rhode island contained e. chaf ... | 2000 | 11101616 |
| Southern Tick-Associated Rash Illness (STARI) in the North: STARI following a tick bite in Long Island, New York. | The most common clinical manifestation of Lyme disease is the characteristic rash, erythema migrans (EM). In the 1980s EM-like eruptions were reported in Missouri and other southeastern states. The EM-like eruptions, which were of unknown etiology, often followed the bite of the Lone Star tick (Amblyomma americanum) and the rash is called STARI (southern tick-associated rash illness). Although the Lone Star tick is found in the Lyme disease-endemic areas of New England and Mid-Atlantic regions o ... | 2011 | 21940418 |
