infection and co-infection rates of anaplasma phagocytophilum variants, babesia spp., borrelia burgdorferi, and the rickettsial endosymbiont in ixodes scapularis (acari: ixodidae) from sites in indiana, maine, pennsylvania, and wisconsin.in total, 394 questing adult blacklegged ticks, ixodes scapularis say (acari: ixodidae), collected at four sites were analyzed by polymerase chain reaction (pcr) for five microbial species: anaplasma phagocytophilum, babesia microti, babesia odocoilei, borrelia burgdorferi, and the rickettsial i. scapularis endosymbiont. identities of genetic variants of a. phagocytophilum were determined by sequencing a portion of the 16s dna. in 55% of infected ticks (193/351), a single agent was detected. in ...200818402145
spread of ixodes scapularis (acari:ixodidae) in indiana: collections of adults in 1991-1994 and description of a borrelia burgdorferi-infected population.collection records for the adult black legged tick, ixodes scapularis say, in indiana for the period 1991-1994 are presented and a new, established population of borrelia burgdorferi-infected i. scapularis is described. the number of i. scapularis adults collected in indiana increased progressively from 19 in 1991 to > 200 in 1994, and the number of indiana counties reporting at least 1 adult increased from 13 to 29. also, during this period, 4 countries in northwestern indiana yielded > 10 spec ...19968840696
collections of adult ixodes dammini in indiana, 1987-1990, and the isolation of borrelia burgdorferi.the collection records for ixodes dammini spielman, clifford, piesman & corwin in indiana are summarized for the period 1987-1990. in 1990, 13 of 729 deer examined were found to harbor adult i. dammini ticks. eleven of these ticks were collected from 10 deer at a site in newton county in northwestern indiana. borrelia burgdorferi spirochetes were isolated from a single female i. dammini tick collected from this site.19911941948
forest and surface water as predictors of borrelia burgdorferi and its vector ixodes scapularis (acari: ixodidae) in indiana.the objective of this study was to assess whether the distribution of borrelia burgdorferi, the causative agent of lyme disease, and its vector tick ixodes scapularis say (acari: ixodidae) across indiana is influenced by large-scale landscape features, specifically the proportion of forest within the surrounding landscape and the distance to water features such as lakes and major streams. hunter-killed deer were checked for ticks in designated check-stations in the opening firearm hunting season ...201020496594
surveillance of lyme disease in the united states, 1982.lyme disease is a tick-borne illness that has been reported from three regions in the united states--the northeast, midwest, and west--which correspond to the distribution of the recognized vectors of the disease, ixodes dammini and ixodes pacificus. in 1982, a surveillance system designed to define the morbidity and geographic distribution for lyme disease by using a clinical case definition received information on 491 definite cases and 38 probable cases. of the definite cases, 489 were acquir ...19853998509
serologic survey for selected infectious disease agents in swift and kit foxes from the western united states.a serologic survey of swift fox (vulpes velox) and kit fox (v. macrotis) from the western usa was conducted for 12 infectious diseases. samples from swift fox were collected between 1987 and 1992 from colorado (n = 44), kansas (n = 10), and wyoming (n = 9). samples from kit fox were collected in california (n = 86), new mexico (n = 18), utah (n = 9), and arizona (n = 6). overall antibody prevalence rates were 33 of 110 (30%) for canine parvovirus (cpv), 9 of 72 (13%) for canine distemper virus ( ...200011085448
white-tailed deer (odocoileus virginianus) as a potential sentinel for human lyme disease in indiana.we assessed the potential of white-tailed deer (wtd) (odocoileus virginianus) to be a sentinel for human cases of lyme disease (ld) in indiana using location data from a 3-year survey of approximately 3400 hunted deer with associated tick ixodes scapularis and borrelia burgdorferi (bb) data. data on human ld cases at the county level were obtained from the indiana department of health. all data were assigned to county centroids to match the resolution of the ld data before creating optimized tre ...201322776734
lyme disease: a review and an outlook for indiana. 19892656848
the use of harvested white-tailed deer (odocoileus virginianus) and geographic information system (gis) methods to characterize distribution and locate spatial clusters of borrelia burgdorferi and its vector ixodes scapularis in indiana.ixodes scapularis (say) is the vector for borrelia burgdorferi (bb) the causative agent of lyme disease (ld). the increased number and presence of ticks in the environment pose a significant health risk to people and many domestic animals including dogs, cats, and horses. this study characterized the distribution and expansion of i. scapularis and bb and identified areas of increased risk of ld transmission in indiana using geographical information systems (gis) and spatial analysis. a cross-sec ...200919272000
community health nurses' knowledge of lyme disease: implications for surveillance and community education.a statewide assessment was conducted to determine the general knowledge and professional practices about lyme disease (ld) of local health department nurses. the study sample included 226 nurses practicing in 80 health departments in indiana. data were collected using a self-administered questionnaire and analyzed using group independent t tests. findings showed that nurses were most knowledgeable about personal protection against ld and least knowledgeable about symptoms, case definition, and r ...199910091472
