Argas vespertilionis, an argasid tick associated with bats and bat habitats in Europe, Africa, and Asia has been reported to bite humans; however, studies investigating the presence of vector-borne pathogens in these ticks are lacking. Using molecular tools, we tested 5 A. vespertilionis ticks collected in 2010 from the floor of a bat-infested attic in southwestern France that had been converte...

A total of 472 field-collected Ixodes ricinus ticks from southern Germany were investigated by immunofluorescence for the presence of Borrelia burgdorferi with a polyvalent rabbit immune serum and with monoclonal antibodies specific for outer surface proteins A and C (OspA and OspC, respectively). Borreliae were detected in 90 ticks with the polyvalent immunofluorescence assay. Infection rates ...

Field collections of ticks from two breeds of cattle in the North Western Transvaal showed the common tick species to be Rhipicephalus appendiculatus, Amblyomma hebraeum, Rhipicephalus evertsi evertsi and Hyalomma marginatum rufipes. The number of these ticks was higher on Simmentaler than on Brahman cattle. Correlation was found between the number of ticks on the cattle and their serum gamma g...

Adult Ixodes ricinus (Acari: Ixodidae) ticks collected near Ljubljana, Slovenia, were tested for the agent of human granulocytic ehrlichiosis (HGE) by using PCR assays based on the 16S rRNA gene. Three (3.2%) of 93 ticks were found to contain granulocytic ehrlichiae. Nucleotide sequences of portions of the bacterial groESL heat shock operon amplified from these ticks were identical or nearly (9...

background : this comprehensive study was conducted on multi-purpose one-humped camel ( camelus dromedarius ) sera and ticks to assess the epidemiological aspects of the crimean-congo hemorrhagic fever virus (cchfv) in northeast iran. methods : from may 2012 to january 2013, eleven cities were randomly selected in the khorasan provinces of iran as “clusters,” and at least 14 one-humped camels w...

To assess the potential role of ticks as carriers of West Nile virus (WNV) and Usutu virus (USUV), we tested 1721 ticks from 379 wild birds in Northwestern Italy between 2012 and 2014. Ticks were analyzed in pools using a pan-flavivirus real-time RT-PCR and positive pools were subjected to RT-PCR for USUV and WNV genome detection. All the tested samples resulted negative, suggesting that Ixodes...

The aim of this study was to improve understanding of several factors related to the ecology and environmental risk of Borrelia infection in northern Florida. Small mammals and host-seeking adult ticks were collected at several sites, and specimens were tested for the presence of Borrelia species, primarily by PCR amplification. Tissues from some vertebrates and ticks were initially cultured in...

Ticks and blood samples were collected from white-tailed deer (Odocoileus virginianus) in forests located in an insular, urban area of Bridgeport, Conn., and in rural south central Connecticut during 1992 and 1993. Immature and adult Ixodes scapularis ticks were tested for Borrelia burgdorferi, the etiologic agent of Lyme borreliosis, by indirect fluorescent-antibody staining methods. Deer sera...

The effect of introduced large herbivores on the abundance of Ixodes ricinus ticks and their Borrelia infections was studied in a natural woodland in The Netherlands. Oak and pine plots, either ungrazed or grazed by cattle, were selected. Ticks were collected weekly by blanket dragging. Borrelia infections were determined by PCR and restriction fragment length polymorphism. Rodent densities wer...
