ability of the lyme disease spirochete borrelia burgdorferi to infect rodents and three species of human-biting ticks (blacklegged tick, american dog tick, lone star tick) (acari:ixodidae).the infectivity of a diverse collection of borrelia burgdorferi strains from north america for mice was determined as a prelude to vector competence experiments with the 3 primary human-biting tick species in the eastern united states (ixodes scapularis say, dermacentor variabilis (say), amblyomma americanum (l.)]. of the 34 b. burgdorferi strains inoculated into mice, 29 were infectious; the exceptions were 5 isolates from texas. vector competence experiments were conducted with 2 strains from ...19979220680
invasion of the lyme disease vector ixodes scapularis: implications for borrelia burgdorferi endemicity.lyme disease risk is increasing in the united states due in part to the spread of blacklegged ticks ixodes scapularis, the principal vector of the spirochetal pathogen borrelia burgdorferi. a 5-year study was undertaken to investigate hypothesized coinvasion of i. scapularis and b. burgdorferi in lower michigan. we tracked the spatial and temporal dynamics of the tick and spirochete using mammal, bird, and vegetation drag sampling at eight field sites along coastal and inland transects originati ...201020229127
use of tick surveys and serosurveys to evaluate pet dogs as a sentinel species for emerging lyme disease.to evaluate dogs as a sentinel species for emergence of lyme disease in a region undergoing invasion by ixodes scapularis.200919119948
lyme disease spirochetes in ticks collected from birds in midwestern united states.in a tick-spirochete survey conducted from all 1989 through fall 1992 in north-western wisconsin, 4,256 birds (composed of 91 species) were examined for ticks. infestations were recorded for 400 birds (composed of 30 species). of 1,184 ticks taken from 335 birds (composed of 26 species), 60 (5%) haemaphysalis leporispalustris (packard) from 8 species of birds were infected with the lyme disease spirochete. borrelia burgdorferi johnson, schmid, hyde, steigerwalt & brenner. similar surveys conduct ...19968667384
geographic distribution of ticks (acari: ixodidae) in michigan, with emphasis on ixodes scapularis and borrelia burgdorferi.a 12-yr (1985-1996) passive survey in michigan based upon tick submissions from citizens yielded 4,755 ticks of 21 species, 16 of which were probably indigenous in the state. three species of dermacentor [most common, d. variabilis say and d. albipictus (packard)]; 2 species of amblyomma [most common, a. americanum (l.)]; and 12 species of ixodes (most common, i. cookei packard and i. scapularis say), as well as haemaphysalis leporispalustris (packard), rhipicephalus sanguineus latreille, and th ...19989775623

isolation of borrelia burgdorferi from two patients in michigan.borrelia burgdorferi was isolated from skin biopsy specimens of erythema chronicum migrans lesions on two individuals residing in menominee county, michigan, in 1992. to our knowledge, these are the first two cases of culture-confirmed lyme disease in michigan. in spite of prompt treatment and resolution of illness, antibodies to b. burgdorferi were detectable for at least 3 months in both patients. both specimens were obtained at different rural medical practices, thus demonstrating that with a ...19947893885

prevalence of borrelia burgdorferi in host-seeking ticks (acari: ixodidae) from a lyme disease endemic area in northern michigan.the lyme disease spirochete, borrelia burgdorferi johnson, schmid, hyde, steigerwalt & brenner, was recovered from the guts of questing ixodes scapularis say adults and nymphs and adult dermacentor variabilis (say), collected in menominee county, michigan, in 1992. spirochetes were cultured successfully from guts placed in modified barbour-stoenner-kelly ii medium held in 5-ml cultures tubes or in 0.3-ml wells of microtiter plates. most isolates were recovered within 2 wk of culturing at an incu ...19947932597
predicting the risk of lyme disease: habitat suitability for ixodes scapularis in the north central united states.the distribution and abundance of ixodes scapularis were studied in wisconsin, northern illinois, and portions of the upper peninsula of michigan by inspecting small mammals for ticks and by collecting questing ticks at 138 locations in state parks and natural areas. environmental data were gathered at a local level (i.e., micro and meso levels), and a geographic information system (gis) was used with several digitized coverages of environmental data to create a habitat profile for each site and ...200211927027
lyme disease surveillance--united states, 1989-1990.surveillance for lyme disease (ld) was initiated by cdc in 1982 (1), and in january 1991, ld became nationally reportable (2). forty-six states reported cases in 1989 and 1990 (figure 1), but the occurrence in nature of the causative bacterium, borrelia burgdorferi, has not been documented in all of these states. from 1982 through 1989, the annual reported number of cases of ld increased 18-fold (from 497 to 8803, respectively) and from 1986 through 1989, nearly doubled each year (figure 2). the ...19912046649
associations of passerine birds, rabbits, and ticks with borrelia miyamotoi and borrelia andersonii in michigan, u.s.a.wild birds contribute to maintenance and dissemination of vectors and microbes, including those that impact human, domestic animal, and wildlife health. here we elucidate roles of wild passerine birds, eastern cottontail rabbits (sylvilagus floridanus), and ixodes dentatus ticks in enzootic cycles of two spirochetes, borrelia miyamotoi and b. andersonii in a region of michigan where the zoonotic pathogen b. burgdorferi co-circulates.201223057837
