Occurrence of ixodes scapularis and borrelia burgdorferi in the fragmented landscapes of east-central and northeast Illinois
The distribution of Ixodes scapularis and Borrelia burgdorferi has continued expanding in Illinois over the past twenty years. However, the extent to which this tick vector and etiologic agent of Lyme disease has spread is not well known. In east-central Illinois (ECIL), I evaluated habitat …

THE EFFECT OF BIOTIC AND ABIOTIC FACTORS WITHIN THE SOIL ENVIRONMENT ON THE MORTALITY OF IXODES SCAPULARIS DURING THEIR OFF-HOST PERIODS
The blacklegged tick (Ixodes scapularis) is the primary vector for multiple widespread tick-borne diseases in the United States, including anaplasmosis, babesiosis, Powassan virus, and Lyme disease. This species spends most of its two-year life cycle either questing for hosts on leaf litter and …

The expanding distribution of Ixodes scapularis and associated pathogens in the Chicago, IL, metropolitan area
… primary vector of Lyme disease, the tick Ixodes scapularis (Acari: Ixodidae), has expanded its range concurrently with the disease including into urban landscapes. To investigate landscape factors that may influence the colonization of I. scapularis and its associated pathogens in an urban …

Ticks And Tick-Borne Pathogens In North Dakota
… species: Dermacentor variabilis (1449), Ixodes scapularis (307), Ixodes woodi (3), Ixodes angustus (2), and Amblyomma americanum (1). Dermacentor variabilis were collected in all areas of the state while I. scapularis were restricted to the northeast portion of the state. This provided …

One tick closer to a better understanding of tick physiology and how to incorporate tick biology in a classroom
The black-legged tick, Ixodes scapularis (Acari: Ixodidae), transmits pathogens that can have detrimental effects on human and wildlife health. The pathogens that I. scapularis transmits include the causative agents of Lyme disease and Powassan virus disease. Due to various human impact factors …

A community modeling approach to understanding the ecology of Lyme disease
The black-legged tick (Ixodes scapularis) is responsible for transmitting the Lyme disease pathogen (Borrelia burgdorferi) to humans in eastern North America. Since the 1970s, the geographic distributions of both the pathogen and the black-legged tick have expanded throughout the US. This expansion …

Exploring the Neuropeptides, Neuropeptide Receptors and Neurotransmitter Receptors in the Synganglia of Part-Fed Females of <i>Ornithodoros turicata</i> (Argasidae) and <i>Ixodes scapularis</i> (Ixodidae) with Insights Into Their Roles in Contrasting Biology
… system) of the Lyme disease tick, <em>Ixodes scapularis</em> and the soft tick <em>Ornithodoros turicata</em> was evaluated using Illumina GAII high throughput sequencing which generated high coverage cDNA libraries (transcriptomes). These ticks exhibit different biological patterns of …

Transmission Competence of B. burgdorferi Infected Ixodes Ticks and Development of an OspC-Based Lyme Disease Vaccine
… understanding the role of the vector Ixodes scapularis (I. scapularis) as the agent that carries the spirochete which is important to limit the occurrence of Lyme disease. Once we understand the vector-pathogen response, it also becomes important to determine the remedies for Lyme disease. …

Modeling host responses to tick feeding and tick-borne flavivirus evolution and dispersal
… initial and subsequent infestations with Ixodes scapularis and Dermacentor andersoni nymphs was characterized using PCR-array, microarray, histopathology, and protein-detection methods. These studies show a pro-inflammatory innate-like immune response characterized by cytokines IL-1b, IL-6, …
