We employed a direct metagenomic approach via next-generation sequencing for a cross-sectional investigation of viruses in 10 tick pools, collected from Aegean, Mediterranean and central Anatolian locations in Turkey. Sequences from all genome segments of Tamdy orthonairovirus (family Nairoviridae) were characterized in ticks collected from a Meriones tristrami. We further obtained near-complete L and partial S segments of several tick-associated phleboviruses (family Phenuiviridae), including Tacheng tick virus 2 and a novel virus, tentatively named as the tick phlebovirus Anatolia. Partial NS5-coding region of recently-described flavi-like virus (Tacheng tick virus 8) was further detected. Moreover, near-complete and polymerase-coding regions of arthropod-associated rhabdoviruses as well as sequences closely-related to the members of the newly-proposed virus family, the Chuviridae, were characterized. Despite origins of the viral sequences could not be fully elucidated, the findings suggest the circulation of diverse arthropod and tick-associated viruses in Anatolia. Occurrence and outcome of vertebrate exposure and probable health impact of these viruses require further investigation. We also report the initial detection of Tamdy orthonairovirus, an established human pathogen, which should be included in the diagnostic workup of infections with unknown etiology.
