BACKGROUND Argasid ticks (soft ticks) are blood-feeding arthropods that can parasitize rodents, birds, humans, livestock and companion animals. Ticks of the Ornithodoros genus are known to be vectors of relapsing fever borreliosis in humans. In Algeria, little is known about relapsing fever borreliosis and other bacterial pathogens transmitted by argasid ticks. METHODOLOGY/PRINCIPAL FINDINGS ...

objective: relapsing fever caused by borrelia persica is an acute tick-borne disease which is transmitted by soft ticks of ornithodoros tholozani to human. the disease is reported from middle east and many regions of iran. detection of infection is problematic since the suspected infected ticks should be fed on animal hosts such as guinea pigs and subsequently after 7-14 days, the animal blood ...

Soft ticks, Argas vespertilionis, were collected from feces of bats in Japan. Cytopathic effect (CPE) was observed after inoculating the homogenates of ticks to Vero cells. Sequencing of RNA extracted from the cell supernatant was performed by next generation sequencer. The contigs had identity to segments of Bunyaviruses, Issyk-Kul virus. The identities of segment L, M and S were only 77, 76 a...

Bacterial endosymbionts of ticks are of interest due to their close evolutionary relationships with tick-vectored pathogens. For instance, whereas many ticks contain Francisella-like endosymbionts (FLEs), others transmit the mammalian pathogen Francisella tularensis. We recently sequenced the genome of an FLE present in the hard tick Amblyomma maculatum (FLE-Am) and showed that it likely evolve...

background: relapsing fever caused by borrelia persica , is an acute tick-borne disease which is transmitted by soft ticks of ornithodoros tholozani to human.     methods: value of pcr and xenodiagnosis for detection of b. persica in o. tholozani ticks was compared. sixty-four bor­relia -free ticks were fed on infected guinea pigs and used for the experiments. for xenodiagnosis, a group of 32 t...

We report a case of infestation long-term laboratory colony soft ticks, Ornithodoros moubata, with mites that were molecularly identified as Tyrophagus fanetzhangorum using the COI gene and discuss possible nature interaction between these two acarines.

In this paper, the authors report ticks parasitizing bats from the Serra das Almas Natural Reserve (RPPN) located in the municipality of Crateús, state of Ceará, in the semiarid Caatinga biome of northeastern Brazil. The study was carried out during nine nights in the dry season (July 2012) and 10 nights in the rainy season (February 2013). Only bats of the Phyllostomidae and Mormoopidae famili...
