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 …

Exploration of the spatial epidemiology of tick borne pathogens of livestock in Southern Cumbria
… is more abundant in sustainable uplands, pathogens able to exploit both wild-living anddomesticated hosts are of particular concern. Tick-borne pathogens are not only a case in point; butalso their threat is now augmented by increasing tick abundance, changing climate, and theextraordinary …

Molecular Detection of Tick-Borne Pathogens Associated With Ixodid Tick Species Infesting Migratory Songbirds and Ruminants
<p>Ticks are hematophagous arthropods and capable of inoculating various infectious agents to their vertebrate hosts. Ticks attached to birds and ruminants are capable of carrying tick-transmitted microorganisms. In our study, the prevalence of tick-borne pathogens was examined in ticks infesting …

Hard ticks and tick-borne pathogens of domestic and wild animals in Maswa and Iringa, Tanzania
참진드기는 체표에 기생하는 정지동물로서 다양한 병원체를 매개한다. 알에서 깨어나 유충, 약충, 성충의 순으로 탈피하며, 알을 제외한 모든 충체는 흡혈을 한다. 아프리카 탄자니아는 아프리카에서 세 번째로 가축이 많은 나라며, 대부분이 소이다. 본 연구는 탄자니아 마스와 지역과 이링가 지역의 소와 야생동물에서 참진드기와 참진드기 매개 병원체를 동정했다. 참진드기를 형태학적 특징에 따라 동정하였고, genomic DNA를 추출해 PCR을 이용해 매개 병원체를 검출하였다. 두 지역에서 소와 야생동물에서 Amblyomma 속 참진드기 …

Wildlife health in human-modified landscapes: epidemiology of tick-borne pathogens affecting black-backed jackals and caracals
… baseline research on the epidemiology of pathogens occurring in wildlife populations within both rural and urban landscapes has received little attention to date. The aim of this study was to improve our understanding of wildlife health in human-modified landscapes in South Africa, by …

Determining the Prevalence and Distribution of Tick-Borne Pathogens in Southeastern Virginia and Exploring the Transmission Dynamics of Rickettsia Parkeri in Amblyomma Maculatum
<p>Tick-borne pathogens are an increasing threat to human and animal health worldwide. In the United States, cases of Lyme disease, spotted fever rickettsioses, ehrlichiosis and anaplasmosis are on the rise. Factors related to emergence include appearance of a new pathogen, recognition of an …

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 …

Interference with biologic transmission of Anaplasma marginale by targeting the tick-pathogen interface
Ticks are globally renowned vectors for numerous zoonoses. Ixodid ticks transmit a variety of viral, bacterial, and protozoan pathogens to their vertebrate hosts. Because of the expansion of the geographic ranges of both ticks and pathogens, increasing tick populations, emerging tick-borne …

Maintaining pathogens with short infectivity in seasonally structured tick populations: relative importance of three transmission pathways
Infectivity periods of different tick-borne pathogens in host species can vary widely, and the variation affects how the pathogens are maintained in tick populations. In addition to systemic and vertical transmission, cofeeding transmission has been proposed as an important route for the …

Molecular detection and factors associated with selected tickbone zoonoses in dogs in Chilanga district in Zambia
Vector borne diseases, also referred to as zoonoses, have been responsible for some of the worst plagues of mankind. The close relationship between humans and animals increases chances of transmission of vector-borne zoonoses. Among some of these infections are pathogens transmitted by ticks which …

Characterization of the Bacterial Microbiome of Exotic Tick Species Collected from Migratory Birds
… natural/accidental hosts to ectoparasites like ticks (predominantly immature stages) and are known reservoirs of several pathogens transmitted by ticks. Parasitizing these birds, exotic tick species often hitch rides to non-native ecological niches, bringing along tick-borne pathogens. This …

Characterizing ERAD and Antioxidant Response in Ixodes scapularis ISE6 Cells during Borrelia Infection
<p>Ticks are hematophagous ectoparasites that transmit a multitude of diseases to humans. <em>Borrelia burgdorferi</em> (BB) and <em>Borrelia miyamotoi </em>(BM) are both tick-borne pathogens that cause disease in humans and are transmitted by the black-legged tick (<em>Ixodes scapularis). </em>A …

Tick abundance and microorganism diversity in the 11 counties comprising the Choctaw Nation of Oklahoma
Tick-borne disease is an expanding public health concern within the United States. This is particularly true across the southcentral region where ecological diversity and human/vector interactions are highly variable. Southeastern Oklahoma encompasses the 11 counties that are within the Choctaw …

Evaluating the Prevalence of Tick-Borne Viruses Circulating in Virginia Using a One-Health Approach
Ticks are hematophagous ectoparasites capable of transmitting various pathogens, including bacteria, protozoa, and viruses, to vertebrates. In the United States, tick-borne pathogens are responsible for around 95% of arthropod-borne diseases. Lyme disease is the most common tick-borne illness. …

Modeling host responses to tick feeding and tick-borne flavivirus evolution and dispersal
Ixodid ticks are hematophagous arthropods that feed on host animals for an extended period of time. To facilitate feeding, ticks secrete a complex mixture of salivary molecules that inhibit host responses such as coagulation, complement, itch responses, and immune responses. Ticks act as vectors …

The Spatial and Molecular Epidemiology of Lyme Disease in Eastern Ontario
Lyme disease is an emerging tick-borne illness in Canada, with human case numbers increasing 15- to 20-fold since Lyme disease became nationally notifiable in 2009 until the present. In Ontario, Canada's largest province by population, average Lyme disease incidence across the province is similar …
