“…This is a low level of infestation relative to most other published surveys of hunter-harvested deer, in both endemic and nonendemic areas (e.g., Amerasinghe et al 1993;Cortinas and Kitron 2006;Gill et al 1993;Keefe at al. 2009;Kitron et al 1992;Loken et al 1985;Magnarelli et al 1986Magnarelli et al , 1995Riehle and Paskewitz 1996). In these cited studies, deer infestation averaged 57% in Þve LD-endemic states and 35% in three nonendemic states.…”

Borrelia burgdorferi Not Detected in Widespread Ixodes scapularis (Acari: Ixodidae) Collected From White-Tailed Deer in Tennessee

Lyme disease (LD), caused by the bacterium Borrelia burgdorferi and transmitted in the eastern United States by blacklegged ticks, Ixodes scapularis Say, is classified as nonendemic in Tennessee and surrounding states in the Southeast. Low incidence of LD in these states has been attributed, in part, to vector ticks being scarce or absent; however, tick survey data for many counties are incomplete or out of date. To improve our knowledge of the distribution, abundance, and Borrelia spp. prevalence of I. scapularis, we collected ticks from 1,018 hunter-harvested white-tailed deer (Odocoileus virginianus (Zimmerman)) from 71 of 95 Tennessee counties in fall 2007 and 2008. In total, 160 deer (15.7%) from 35 counties were infested with adult I. scapularis; 30 of these counties were new distributional records for this tick. The mean number of I. scapularis collected per infested deer was 5.4 +/- 0.6 SE. Of the 883 I. scapularis we removed from deer, none were positive for B. burgdorferi and one tested positive for B. miyamotoi. Deer are not reservoir hosts for B. burgdorferi; nevertheless, past surveys in northern LD-endemic states have readily detected B. burgdoreferi in ticks collected from deer. We conclude that I. scapularis is far more widespread in Tennessee than previously reported. The absence of detectable B. burgdorferi infection among these ticks suggests that the LD risk posed by I. scapularis in the surveyed areas of Tennessee is much lower than in LD-endemic areas of the Northeast and upper Midwest.

“…Borrelia burgdorferi has been isolated from hepatic tissues of a veery (Anderson et al 1986), but despite numerous attempts to recover this agent from other field-caught birds, yields have been very low. The currently used culture methods are far more efficient in recovering B. burgdorferi from tick tissues, including specimens removed from birds (Anderson et al 1990), and from the blood and internal organs of white-footed mice Anderson et al 1985;Loken et al 1985). Improved culture methods and more timely sampling of birds may help increase the number of bird isolates.…”

1992. Borrelia burgdorferi in 1.rodes dummini (Acari: Ixodidae) feeding on birds in Lyme. Connecticut, U.S.A. Can. J. Zool. 70: 2322Zool. 70: -2325. Passerine birds were captured in Japanese mist nets in Lyme, Connecticut, during 1990 and 1991 to collect larval and nymphal Ixodes dammini and to identify potential bird reservoirs for Borrelia burgdorferi, the etiologic agent for Lyme borreliosis. Of the 329 1 birds captured and recaptured (32 %), 503 in 35 species were parasitized by I. dammini. Ninety-eight of the recaptured birds had ticks attached. Borrelia burgdorferi was detected by indirect immunofluorescence staining in 72 (4.7%) of 15 18 larvae and in 114 (23.3%) of 490 nymphs tested. Prevalence of infected larvae was comparatively greater for specimens removed from veeries (2 1.4 % , n = 140 tested), Carolina wrens (15.5 % , n = 84), hooded warblers (8.9 % , n = 79), and house wrens (8.6%, n = 58). Based on the presence of infected larval ticks on birds, members of these 4 host species have the greatest potential for being reservoirs of B. burgdorferi. Relatively lower percentages of infected larvae (0.3-6.7%) were recorded for 8 other bird species. June through mid-August is a suitable time to isolate B. burgdorferi from natural populations of birds or ticks feeding on avian hosts. MAGNARELLI, L. A., STAFFORD, K. C., 111, et BLADEN, V. C. 1992. Borrelici burgdorjeri in Lrodes dammini (Acari: Ixodidae) feeding on birds in Lyme, Connecticut, U.S.A. Can. J. Zool. 70 : 2322-2325. Des oiseaux passereaux ont ete captures dans des filets japonais a Lyme, Connecticut, en 1990 et 1991, permettant ainsi la recolte de larves et de nymphes d'lxodea dammini et, par le fait meme, ]'identification de reservoirs potentiels de Borrelia burgdorjeri, agent etiologique de la borreliose de Lyme. Des 329 1 oiseaux captures et recaptures (32 %). 503, appartenant a 35 especes, etaient parasites par Ixodes dammini. Quatre-vingt-dix-huit des oiseaux recaptures portaient des tiques. Des Borrelia burgdorjeri ont it6 detectes par coloration immunofluorescente chez 72 (4,7 %) des 15 18 larves et chez 1 14 (23,3 %) des 490 nymphes examinies. La prevalence des larves infectees etait plus importante lorsque les acariens provenaient de Grives fauves (2 1,4%, n = 140 examinees), de Troglodytes de Caroline (15.5 !%, n = 84), de Parulines 2 capuchon (8,9%, n = 79) ou de Troglodytes familiers (8,6, n = 58). D'aprks le fardeau de larves infectees trouvi chez les oiseaux, il semble que ce soient ces 4 especes h6tes qui aient le plus de chances d'etre des riservoirs de B. burgdorferi. Des pourcentages relativement plus faibles de larves infectees (0,3 -6,7%) ont it6 enregistres chez 8 autres especes d'oiseaux. La periode comprise entre juin et le milieu d'aoQt constitue la piriode idiale pour obtenir des B. burgdorferi chez des populations d'oiseaux ou chez des tiques parasites d'oiseaux.[Traduit par la redaction]

“…This biodiverse system sustains at least 9 tick species. Several small mammals inhabiting the Kenora area are known to be reservoir-competent hosts of B. burgdorferi s.l., namely deer mice [23,24], eastern chipmunk, Tamias striatus [25,26], meadow voles [27], northern short-tailed shrew [4,28], and southern red-backed voles [29]. Although white-tailed deer are not competent reservoirs of B. burgdorferi s.l., they support the reproduction of I. scapularis ticks [30].…”

“…Notably, I. angustus is a competent vector of Lyme disease spirochetes [34], and the deer mouse is a reservoir-competent host [23,24]. This nidicolous tick species feeds primarily on rodents and shrews, and the male stays in the host nest to mate with females [36].…”

We detected the Lyme disease bacterium, Borrelia burgdorferi sensu lato (s.l.), in 8 species of ixodid ticks (Acari: Ixodidae) collected from mammalian hosts, including humans, at Kenora, Ontario, Canada. These 8 tick species include Ixodes angustus, Ixodes banksi, Ixodes cookei (groundhog tick), Ixodes gregsoni, Ixodes muris (mouse tick), Ixodes scapularis (blacklegged tick), Haemaphysalis leporispalustris (rabbit tick), and Dermacentor albipictus (winter tick). Based on PCR amplification, 39 (41%) of 94 ticks tested were positive for B. burgdorferi s.l. DNA sequencing of the flagellin B (flaB) gene of B. burgdorferi s.l. complex revealed the presence of B. burgdorferi sensu stricto (s.s.), which is pathogenic to humans, and causes diverse neurological manifestations in patients. Notably, we provide the first record of B. burgdorferi s.l. in I. gregsoni, and reveal a new distribution record for this tick in eastern and central Canada by extending the known range westward by 200 km. Our findings indicate that there may be a wide-ranging enzootic transmission cycle of B. burgdorferi s.l. within the ecosystem throughout the Kenora area. The health-care profession must be fully cognisant that Lyme disease is present in the Kenora area, and is a public health risk.
