Abstract:
... The aim of this study was to document the presence of Rickettsia spp. in ticks parasitizing wild birds in Costa Rica. Birds were trapped at seven locations in Costa Rica during 2004, 2009, and 2010; then visually examined for the presence of ticks. Ticks were identified, and part of them was tested individually for the presence of Rickettsia spp. by polymerase chain reaction (PCR) using primers ta ...

Abstract:
... From April to October 2007, host-seeking Ixodes ricinus ticks were collected from four locations in southern Norway; Farsund, Mandal, Søgne and Tromøy, respectively. Larvae (n=210), nymphs (n=1130) and adults (n=449) were investigated for infection with Borrelia miyamotoi by real-time polymerase chain reaction (PCR) amplification of part of the 16S rRNA gene. Results were verified by direct sequen ...

Abstract:
... Crimean-Congo hemorrhagic fever (CCHF) is a tick-borne disease caused by CCHF virus (CCHFV) of the genus Nairovirus in the family Bunyaviridae. CCHFV causes subclinical infection in domestic livestock and an often fatal hemorrhagic illness in humans, with approximately 30% mortality rates. In the present study, a cross-sectional serosurvey was conducted in a total of 282 randomly selected cattle f ...

Abstract:
... Anaplasma marginale is the most prevalent tick-borne pathogen in cattle in tropical and subtropical regions of the world. Major Surface Protein 1a (MSP1a) has been found to be a stable genetic marker for identifying A. marginale isolates within geographical regions. It is conserved in cattle during infection and tick-borne transmission of the pathogen. The aim of the present longitudinal study was ...

Abstract:
... Current strategies to control cattle ticks use integrated control programs (ICP) that include vaccination. Reduction in the use of chemicals and in the cost of tick control, the delay or elimination of acaricide resistance and the decreasing of environmental pollution are the advantages of using these programs. This integrated program is potentially applicable to all genotypes of chemical resistan ...

Abstract:
... Dermacentor reticulatus is widespread throughout Europe and is expanding its range in several European countries. It is associated with a number of different pathogens. Its role in the transmission of disease to humans is currently small; however, it might play an important role in the maintenance of pathogens in enzootic cycles. The ecology of D. reticulatus, especially of the immatures, is not w ...

A wide range of geographic strains of A. marginale have been isolated from cattle, several of which have been characterized using genomics and proteomics. While many of these strains have been propagated in tick lines, comparative analyses after propagation in tick cells have not been re ...

Abstract:
... Small mammals serve as reservoir hosts for tick-borne pathogens, especially for those which are not transmitted transovarially in ticks – such as Babesia microti. Molecular investigations on the prevalence of B. microti in wild small mammals and on attached ticks from differently structured areas may provide information on the circulation of B. microti in different ecological niches. In 2012 and 2 ...

Abstract:
... Nuclear ribosomal RNA (18S and 28S rRNA) and mitochondrial genomes are commonly used in tick systematics. The ability to retrieve these markers using next-generation sequencing was investigated using the tick Nuttalliella namaqua. Issues related to nuclear markers may be resolved using this approach, notably, the monotypic status of N. namaqua and its basal relationship to other tick families. Fou ...

Abstract:
... Ticks are the most significant vectors of infectious diseases in the United States, inspiring many researchers to study aspects of their biology, ecology, and their effects on public health. However, regional differences in tick abundance and pathogen infection prevalence result in the inability to assume results from one area are relevant in another. Current local information on tick ranges, infe ...

In return, risk assessment and disease mapping on human cases might be hampered due to high and inhomogeneous vaccination rates and travel habitats of humans. The roe deer was used to obtain a starting point for the integral view on the actual risk of TBE in A ...
