In the absence of vaccine licensed for use in humans, primary prevent...

In this study, we compared factors that may have an influence on DNA extraction namely commercially available DNA extraction kits vs alkaline hydrolysis for DNA extraction. The methods were applied to questing Ixodes (I.) ricinus ticks and Borrelia cultures of defined cell concentrations. A total of 69 questing I. ricinus ticks were collected. From 34 ticks, total DNA was extracted using a commercial DNA extraction kit. Thirty-five ticks were treated with 1.25 % ammonium hydroxide (NH4OH). Six ticks from each batch were placed in 70 % ethanol (EtOH) for one week prior to DNA extraction to see the effect of EtOH preservatio...

Abstract Tick saliva is a complex mixture of peptidic and non-peptidic molecules that aid engorgement. The composition of tick saliva changes as feeding progresses and the tick counters the dynamic host response. Ixodid ticks such as Ixodes ricinus, the most important tick species in Europe, transmit numerous pathogens that cause debilitating diseases, e.g. Lyme borreliosis and tick-borne encephalitis. Tick-borne pathogens are transmitted in tick saliva during blood feeding; however, saliva is not simply a medium enabling pathogen transfer. Instead, tick-borne pathogens exploit saliva-induced modulation ...

ConclusionsWith co-infection of tick-borne pathogens being commonplace, diagnostic improvements remain important. Developing in vivo models might allow more insight into human pathogenesis. Continued ecological and human case studies are key to better epidemiological understanding, guiding intervention strategies. PMID: 31064634 [PubMed - in process]

Publication date: Available online 22 April 2019Source: Ticks and Tick-borne DiseasesAuthor(s): Pavel Švec, Václav Hönig, Dana Zubriková, Maria Wittmann, Kurt Pfister, Libor GrubhofferAbstractResearch projects in the field of eco-epidemiology of tick-borne diseases often require extensive sampling of arthropod vectors in the field. The aim of our study was to use geographical information systems (GIS) to select appropriate sampling sites of Ixodes ricinus ticks in central European habitat for further ecological studies of vector-borne pathogens (tick-borne encephalitis virus and Borrelia burgdorfe...

Eisen, Goudarz MolaeiAbstractLyme disease is the most prevalent vector-borne disease in the United States. Ixodes scapularis, commonly referred to as the blacklegged tick, is the primary vector of Lyme disease spirochetes, Borrelia burgdorferi sensu lato (s.l.), in the eastern United States. Connecticut has pervasive populations of I. scapularis and remains a hotspot for Lyme disease. A primary aim of this study was to determine if passively collected...

In this study, we applied complementary in silico approaches to modeling how Anaplasma phagocytophilum infection modulates tick vector regulome. This proof-of-concept research provided support for the use of network analysis in the study of regulome response to infection, resulting in new information on tick-pathogen interactions and potential targets for developing interventions for the control of tick infestations and pathogen transmission. Deciphering the precise nature of circuits that shape the tick regulome in response to pathogen infection is an area of research that in the future will advance our knowledge of tick-...

Lyme arthritis, the most common, serious and harmful manifestation during the late stages of Lyme disease, is closely associated with the Borrelia burgdorferi basic membrane protein A (BmpA). Chemokines are also reported to have an importa...
