“…In rodent burrows, we introduced a flexible tube inside and aspirated their contents using a portable petrol-powered aspirator [4] . Ticks from seabird nests were collected after the nesting period; the nests were recovered when the chicks left their nests [5] . The seabird nests were collected between the ratchets in the Agueli Island (Algiers).…”

“…The seabird nests were collected between the ratchets in the Agueli Island (Algiers). The nests were placed in individual bags to avoid parasite loss, and soft ticks were collected [5] . From poultry, ticks were collected from inside wall cracks with entomologic forceps [6] .…”

“…Firstly, ticks were identified by morphologic criteria with standard taxonomic keys [8] . Secondly, each specimen was rinsed twice in distilled water for 10 minutes and dried on sterile filter paper; handling was performed in a laminar flow biosafety cabinet [5] . Ticks were individually crushed in sterile Eppendorf tubes.…”

“…In Algeria, only few studies concerning argasid ticks have been performed, including the first molecular detection of Borrelia crocidurae in Ornithodoros sonrai [4] , the detection of a novel Rickettsia sp. ( Ornithodoros capensis s.s., Ornithodoros erraticus, Ornithodoros rupestris ) [5] , the detection of relapsing fever Borrelia spp., Bartonella spp. and Anaplasmataceae bacteria [6] and the first report of Ornithodoros capensis s.s. in Algiers [7] .…”

“…Knowledge about soft ticks in Algeria is currently incomplete. Some scientific contributions provided information on the species occurring on the island [5] , but now some reports contain data that need to be updated. The present report aims to highlight the distribution of soft ticks in Algeria and the establishment of an updated inventory.…”

Argasid ticks include vectors of relapsing fevers caused by Borrelia spp. in humans, and they can transmit arboviruses and other bacterial pathogens. Knowledge about soft ticks (Ixodida: Argasidae) in Algeria is incomplete, and distribution data need to be updated. Here we report a series of entomologic investigations that we conducted in five different areas in Algeria between 2012 and 2015. Ticks were identified by entomologic keys and molecular tools (16S rRNA gene). Six distinct species belonging to two genera were identified, including Ornithodoros capensis s.s., Ornithodoros rupestris, Ornithodoros occidentalis, Ornithodoros erraticus, Ornithodoros sonrai and Argas persicus. The present study highlights the distribution of soft ticks, the establishment of an update inventory with nine species and associated pathogens detected in argasid ticks in Algeria.
