INVESTIGATION OF THE MIALOME OF IXODES SCAPULARIS REPLETE TICKS AND UNDERSTANDING THE POPULATION GENOMIC STRUCTURE OF IXODES PACIFICUS TICKS
Ticks are blood-feeding arthropod ectoparasites that transmit disease-causing pathogens to humans and animals worldwide. Research on vaccine development to protect humans, companion animals, and livestock from ticks and tick-transmitted pathogens has accelerated by using proteomic and …

Ticks And Tick-Borne Pathogens In North Dakota
<p>In 2010 a statewide survey of ticks and tick-borne pathogens was conducted in North Dakota. Ticks were collected from the four eco-regions in the state by flagging for questing adults and by collecting feeding immature ticks from trapped small mammals. I collected 1762 individual ticks …

Efficacy of fipronil against Amblyomma hebraeum ticks on boer goats and detection of Ehrlichia ruminantium in ticks in Limpopo Province, South Africa
… cryo-preserve E. ruminantium from A. hebraeum ticks from a heartwater endemic region in the Limpopo province of South Africa. It was demonstrated that a 1.0% fipronil pour-on solution is 100% effective and has a persistent efficacy of seven days against A. hebraeum, but only if a targeted …

SURVEY OF Rickettsia spp. IN TICKS IN NACOGDOCHES COUNTY, TEXAS
… parkeri.</em> Over a two-year period, 49 ticks were collected in Nacogdoches county and taxonomically identified. The DNA was extracted using DNeasy Blood and Tissue Kit, and the UltraClean Microbial DNA Isolation Kit. The genomic contents of the tick were subjected to PCR amplification to …

Molecular Phylogenetic Relationships of North American Dermacentor Ticks Using Mitochondrial Gene Sequences
… is a recently evolved genus of hard ticks (Family Ixodiae) that includes 36 known species worldwide. Despite the importance of <em>Dermacentor</em> species as vectors of human and animal disease, the systematics of the genus remain largely unresolved. This study focuses on …

Information visualization of the stock market ticks : toward a new trading interface
Ticks, the second-to-second trades and quotes of a market, might be considered the atoms of finance. They represent the basic, defining transactions that represent an asset in the market. Almost all financial concepts, such as returns or risk, are essentially abstractions from tick data. Like …

The Impact of Powassan Virus and Borrelia burgdorferi Coinfection in Ixodes scapularis Ticks
Ticks (Order: Ixodida) are hematophagous arthropods that transmit a number of medically significant pathogens. Two of these include Powassan virus (POWV) and the spirochete Borrelia burgdorferi, both of which are transmitted by Ixodes scapularis in the northern parts of the United States. Powassan …

Population and migratory dynamics of blacklegged ticks and the Lyme bacterium, Borrelia burgdorferi
… range and population size of blacklegged ticks (Ixodes scapularis) and the pathogens they vector, corresponding with the re-emergence of some of the most prevalent infectious diseases in North America. Relatively little empirical work has investigated the impact of range changes on the …

The structure and function of Gene's organ and its associated glands in ticks
… of Gene's organ, the egg-waxing organ in ticks, using electron microscopy. Both ultrastructural and physiological aspects are investigated in two important pest species, Boophilus microplus and Amblyomma variegatum. The organ performs an essential function in females by coating the eggs …

Engineering Disease Resistance in a Reservoir Species for the Mice Against Ticks Project
This thesis explores the application of genome editing technologies to combat zoonotic infectious diseases through the development of a novel heritable immunization strategy targeting reservoir species. Focusing on Lyme disease, where white-footed mice (Peromyscus leucopus) serve as the primary …

Population Genetic Structure of Ixodes pacificus Ticks and Detection of Their Pathogens In-Silico
Ticks are hematophagous ectoparasites responsible for the transmission of several serious illnesses in humans, domestic animals, livestock, and wildlife. As climate changes and ticks are introduced into new areas by their host, regions unfamiliar with tick-borne disease become vulnerable to …

Molecular Detection and Characterization of Rickettsia sp. in Hard Ticks Collected in Nacogdoches, Texas
… in the United States. Many efforts to control ticks have been made and are continuously being developed. These methods include surveillance of ticks and detection of the tick-borne pathogens.This study examined hard ticks in Nacogdoches, Texas, to test for the presence of <em>Rickettsia …

<i>Ixodes Scapularis</i> SRC Kinase Is Required for Rickettsial Pathogen Survival in Ticks
… It uses<em> Ixodes scapularis</em> ticks as a vector for spreading infection to other mammal species. This bacterium has a specific path for infection through the salivary glands of its vector host. It also suppresses certain functions such as the inhibition of apoptosis and ROS …

The Prevalence of Human Granulocytic Ehrlichiae in <em>Ixodes scapularis</em> Ticks in Southeastern Georgia
… prevalence rate of HGE infection in blacklegged ticks (<em>Ixodes</em> <em>scapularis</em>) in insular and mainland sites in southeastern Georgia using nested PCR techniques. Four locations were studied representing 2 barrier islands and 2 mainland sites. We hypothesized that areas that have low …

An observational study of ticks on the 30 Acre Lake Trail at Turnbull National Wildlife Refuge
<p>Ticks are known carriers of bacterial pathogens that cause diseases in humans and other mammals. Hosts (mice, chipmunks, rabbits, deer, and elk) must be in the tick’s questing range to fulfill the life cycle. The questing range depends on the life stage of the tick, vegetation, and host …
