Tick-borne pathogensVector-borne diseasesBlacklegged ticks (Ixodes scapularis) spend the majority of their life cycle off host, typically in woodland habitat, but require a blood meal at each of three life stages (larva, nymph, adult) to reach maturity and reproduce. Blood feeding usually lasts...
Impressive was the rapid response: all non-fed stages could transition quickly, losing water fast (long day), then slow (short day), and back to fast (long day), with only a single day exposure to short or long day conditions. Short days did not improve the tick’s dehydration ...
Results indicate that managing Japanese barberry will have a positive effect on public health by reducing the number of B. burgdorferi-infected blacklegged ticks that can develop into motile life stages that commonly feed on humans. 展开 关键词: blacklegged tick Japanese barberry Lyme disease white...
for unfed, partially fed (11–21 mg), and replete stages, respectively (Fig. 5). These values are similar to those observed in other tick species7,14,30,34,35. The DA or pilocarpine-induced salivary secretion from partially fed I. scapularis females were 461–484 mOs- mol/L (...
In the western United States, the western blacklegged tick, Ixodes (I.) pacificus Cooley & Kohls, is the primary vector to humans of the Lyme disease spirochete Borrelia burgdorferi sensu stricto (Burgdorfer et al., 1985; Lane et al., 1994). It is also an important vector of Anaplasma ...
For some of these tick species, including members of the Holarctic Ixodes ricinus complex (including I. pacificus, I. persulcatus, I. ricinus, and I. scapularis), the immature stages (larvae and nymphs) often feed on reptiles whereas adults mainly feed on larger mammals, including humans (...
Additionally, using high-throughput DNA sequencing of the 16S rRNA gene, I have provided the first assessment of the internal bacterial community structure across all developmental stages of this tick species. I found Rickettsia to be the relatively abundant bacterial genus across life stages, ...
Drag sampling efficiency, the proportion of the estimated population obtained in a single sample, averaged 6.3% among all stages. Efficiency was not significantly different among stages and was independent of tick density within a given life stage. The population estimation techniques employed in this...
We evaluated the effect of the number of hot (T > 25 掳C), dry (precipitation = 0) days during the questing periods of the two immature Ixodes scapularis life stages (larval and nymphal) on inter-annual variation in Lyme disease incidence between 2000 and 2011 in long-term endemic ...
