Potential role of ticks as vectors of bluetongue virus [PDF]

, 2010
When the first outbreak of bluetongue virus serotype 8 (BTV8) was recorded in North-West Europe in August 2006 and renewed outbreaks occurred in the summer of 2007 and again in 2008, the question was raised how the virus survived the winter.

Development of vaccines against Ornithodoros soft ticks: An update [PDF]

Ticks and Tick-borne Diseases, 2015
Ticks are parasites of great medical and veterinary importance since they are vectors of numerous pathogens that affect humans, livestock and pets. Among the argasids, several species of the genus Ornithodoros transmit serious diseases such as tick-borne human relapsing fever (TBRF) and African Swine Fever (ASF).

Terminal Genome Sequences of the Soft Tick Bunyavirus

Microbiology Resource Announcements, 2020
The complete genome sequence of the soft tick bunyavirus (STBV) was obtained using the Sanger sequencing technique. Comparison with other viral sequences revealed that STBV has unique sequences in the terminal regions that are highly conserved among the genus Orthonairovirus .

Ornithodoros puertoricensis (Ixodida: Argasidae) Associated With Domestic Fowl in Rural Dwellings From Córdoba Department, Caribbean Colombia

Frontiers in Veterinary Science, 2021
Ticks of genus Ornithodoros are nidicolous parasites associated with a wide array of vertebrates. In humans, their bites cause hypersensitivity reactions and are capable to transmit pathogens of health concern.

Maternal Care in the Soft Tick Antricola marginatus

Journal of Parasitology, 2012
Among spiders, scorpions, and whip spiders, a common type of maternal care consists of females carrying newly hatched offspring on their body for a few days until they are able to live independently. While this maternal care has been suggested to occur in different argasid tick species, it has been recorded only once, for Antricola marginatus in Cuba ...

Cell lines from the soft tick Ornithodoros moubata [PDF]

Experimental and Applied Acarology, 2009
Primary cell cultures (n = 16) were initiated from tissues of embryonic and neonatal larval Ornithodoros moubata following methods developed for hard ticks. After maintenance for 20-25 months in vitro, cell multiplication commenced in surviving cultures, leading to the establishment of six cell lines designated OME/CTVM21, 22, 24, 25, 26 and 27.

A novel clade of cysteinyl leukotriene scavengers in soft ticks [PDF]

Insect Biochemistry and Molecular Biology, 2008
Inflammation is an important vertebrate defense mechanism against ecto-parasites for which ticks have evolved numerous mechanisms of modulation. AM-33 and TSGP4, related lipocalins from the soft ticks Argas monolakensis and Ornithodoros savignyi bind cysteinyl leukotrienes with high affinity as measured by isothermal titration calorimetry.

Comparative Analysis of Tick-Borne Relapsing Fever Spirochaetes from Ethiopia and Nigeria

Pathogens, 2023
Despite increasing reports of tick-borne diseases in Africa, remarkably, reports of tick-borne relapsing fever (TBRF) in Nigeria are lacking. Ornithodoros savignyi from Nigeria have been reported with the relapsing fever Candidatus Borrelia kalaharica ...
