“…The highest rate of coinfection with B. burgdorferi and Ba. microti at our study sites was 5.3% at Fire Island National Seashore, whereas coinfection rates as high as 7.7% have been documented at residential sites elsewhere in New York (Feldman et al 2015). …”

“…The rates of coinfection documented here are in general agreement with published rates of coinfections in I. scapularis nymphs with B. burgdorferi and Ba. microti or B. burgdorferi and A. phagocytophilum (Diuk-Wasser et al 2016, Feldman et al 2015). The highest rate of coinfection with B. burgdorferi and Ba.…”

“…For example, in the Mid-Atlantic and Northeastern United States, peridomestic exposure to I. scapularis likely occurs frequently (Falco and Fish 1988, Maupin et al 1991, Klein et al 1996, Connally et al 2006, Feldman et al 2015), whereas in the North-Central United States, recreational exposures are believed to be more common than peridomestic exposures (Kitron and Kazmierczak 1997, Paskewitz et al 2001). Regardless of geographic region, previous studies have demonstrated a risk of human exposure to infected host-seeking I. scapularis nymphs in recreational settings (Falco and Fish 1989, Schulze et al 1992, Oliver and Howard 1998, Paskewitz et al 2001, Han et al 2014, Prusinski et al 2014, Ford et al 2015).…”

Tick-borne pathogens transmitted by Ixodes scapularis Say (Acari: Ixodidae), also known as the deer tick or blacklegged tick, are increasing in incidence and geographic distribution in the United States. We examined the risk of tick-borne disease exposure in 9 national parks across six Northeastern and Mid-Atlantic States and the District of Columbia in 2014 and 2015. To assess the recreational risk to park visitors, we sampled for ticks along frequently used trails and calculated the density of I. scapularis nymphs (DON) and the density of infected nymphs (DIN). We determined the nymphal infection prevalence of I. scapularis with a suite of tick-borne pathogens including Borrelia burgdorferi, Borrelia miyamotoi, Anaplasma phagocytophilum, and Babesia microti. Ixodes scapularis nymphs were found in all national park units; DON ranged from 0.40 to 13.73 nymphs per 100 m2. Borrelia burgdorferi, the causative agent of Lyme disease, was found at all sites where I. scapularis was documented; DIN with B. burgdorferi ranged from 0.06 to 5.71 nymphs per 100 m2. Borrelia miyamotoi and A. phagocytophilum were documented at 60% and 70% of the parks, respectively, while Ba. microti occurred at just 20% of the parks. Ixodes scapularis is well established across much of the Northeastern and Mid-Atlantic States, and our results are generally consistent with previous studies conducted near the areas we sampled. Newly established I. scapularis populations were documented in two locations: Washington, D.C. (Rock Creek Park) and Greene County, Virginia (Shenandoah National Park). This research demonstrates the potential risk of tick-borne pathogen exposure in national parks and can be used to educate park visitors about the importance of preventative actions to minimize tick exposure.

“…Finally, the difference between the two studies could also reflect differences in the sensitivities of our B. burgdorferi detection assays. On the other hand, our nymphal infection rate is in line with other estimates (Diuk-Wasser et al 2012, Feldman et al 2015, States et al 2014, Wang et al 2003. Diuk-Wasser et al (2012)'s sample of over 5000 nymphal Blacklegged Ticks from across the eastern US had a 20% infection rate-very close to our rate.…”

The Density of the Lyme Disease Vector Ixodes scapularis (Blacklegged Tick) Differs between the Champlain Valley and Green Mountains, Vermont

Lyme disease is an emerging infectious disease of public health concern in the northeastern United States. The disease's vector, Ixodes scapularis (Say) (Blacklegged Tick), has increased its range in the past twenty years. In its newly endemic northern range there have been few studies of the Blacklegged Tick's habitat associations. From 2016-2018, we sampled for nymphal Blacklegged Ticks in the Champlain Valley and Green Mountains of Addison County, Vermont, and tested them for Borrelia burgdorferi, the Lyme disease agent. We found 10 times more ticks in the Champlain Valley than in the Green Mountains. Nymphal infection prevalence was 0.21 and did not vary by year or region. The difference in tick density reported has public health consequences, as Vermont has one of the highest rates of Lyme disease in the United States.

“…A body of literature exists that anecdotally recounts the dangers of acquiring tick bites and subsequent Lyme disease through exposure to lawns, but the scientific literature has more nuanced results. Ticks found “in” lawns in studies were closely associated with adjacent woodlands [11–13], or represented part of a pooled sample that included woodland edge and other habitats [14]. Meanwhile, other studies that distinguished between different habitat features in residential landscapes have demonstrated a negative relationship between lawn presence and tick abundance, and a positive relationship with woodlands [4,13].…”

Lawn mowing frequency in suburban areas has no detectable effect on Borrelia spp. vector Ixodes scapularis (Acari: Ixodidae)

Forests have become increasingly fragmented throughout the US, with residential development serving as the primary driver of these changes. These altered landscapes have provided suitable conditions for a broad range of wildlife, including blacklegged ticks and their hosts. Lawns dominate residential landscapes, and thus their management has the potential to reduce the likelihood of contact with ticks in residential yards. We tested the hypothesis that lawn mowing frequency influences tick occurrence in 16 suburban yards in Springfield, MA. We conducted 144 tick drags in lawns of various lawn mowing frequencies (mowed every week, every 2-weeks and every 3-weeks) and did not collect any ticks of any species. Promoting frequent mowing (i.e., shorter lawns) and the removal of grass clippings could have minimal impacts on tick microhabitats, but is consequential for beneficial wildlife and other ecosystem services associated with urban biodiversity.
