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
ixodes dammini (acari: ixodidae) in indiana.ixodes dammini spielman, clifford, piesman and corwin is reported from indiana for the first time. four specimens were taken from deer and one from a dog. all specimens are adult females and all were collected in 1987. the significance of this finding is discussed.19892709389
detection of anaplasma phagocytophilum and babesia odocoilei dna in ixodes scapularis (acari: ixodidae) collected in indiana.the blacklegged tick, ixodes scapularis say, first reported in indiana in 1987, has now been detected in more than half of indiana's counties. the first case of human granulocytic ehrlichiosis (human anaplasmosis) in indiana was reported in 2002. we now report the detection of anaplasma phagocytophilum and babesia odocoilei (emerson and wright 1968) in i. scapularis ticks collected in northern indiana. using polymerase chain reaction analysis, 41 of 193 adult ticks (21.2%) collected from deer we ...200616619631
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
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
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
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
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
