“…To our knowledge, all mesostigmatid mite species identified here are first records for their bat host species and for Pakistan. In the Palaearctic region, St. occidentalis occurs in the European-Caucasian subregion (Orlova et al 2017), therefore the present finding might represent its easternmost record in Eurasia. Similarly, although spinturnicid mites were surveyed in the northern, boreal Palaearctic region, neither Sp.…”

“…In this context, bat ectoparasites represent a very important topic to study (Klimpel & Mehlhorn 2014). Among them, the number of arachnid species (mites, ticks) tends to exceed that of insects in both Europe (Frank et al 2015) and the trans-Palaearctic boreal zone to the Far East (Orlova et al 2017). Blood-sucking arachnids (from Parasitiformes Leach, 1815) can play a role in transmitting vector-borne pathogens not only between bats themselves, but also through the ecological interface connecting bats and domestic animals or humans.…”

Bats are well adapted to inhabit human settlements and are suitable reservoirs of a high number of vector-borne pathogens with veterinary-medical importance. Owing to these eco-epidemiological traits, the importance of studying bat ectoparasites is increasingly recognized. However, relevant molecular-phylogenetic data are missing from several countries of southern Asia, including Pakistan. In this study 11 ectoparasites, collected from bats in northern Pakistan, were analyzed morphologically and/or molecularly, phylogenetically from a taxonomic point of view. In addition, soft ticks were screened for pathogen DNA. Three mesostigmatid mite species were identified: Steatonyssus occidentalis evansi Micherdziński, 1980 and Ancystropus taprobanius Turk, 1950 from Rousettus leschenaultii (Desmarest 1820) and two specimens of Spinturnix americanus (Banks 1902) from Pipistrellus cf. javanicus (Gray 1838). Six soft tick (Carios vespertilionis Latreille, 1802) larvae were also removed from Scotophilus kuhlii Leach, 1821. Morpho-metric comparison revealed minor differences in comparison with C. vespertilionis larvae from Europe (i.e., narrower scutum and longer 4th posterolateral setae, while scutal length and shape index were not significantly different in this context). When molecularly analyzed, C. vespertilionis larvae from Pakistan showed the highest, 94.1% cox1 sequence identity with a sample from Kenya, while in their 16S rRNA gene these had the highest, 96.2–96.4% identity with samples from Europe and central Asia (northwestern China). These findings were confirmed in phylogenetic analyses. A further soft tick larva, collected from R. leschenaultii and therefore provisionally called Argas sp. "rousetti", yielded sequences with only 86.2% and 91% similarities in its cox1 and 16S rRNA genes, respectively, to the genetically closest species, A. boueti. Both Argas species belonged to the phylogenetic group of the subgenus Chiropterargas. Molecular screening of two C. vespertilionis larvae for a broad range of tick-borne pathogens yielded negative results. However, the larva of Argas sp. "rousetti" showed the presence of a spotted fever group (SFG) Rickettsia sp., which (based on four genetic markers) was closely related to two Rickettsia species reported from southeastern Asia (i.e., R. honei and Rickettsia sp. IG-1), but differed more significantly from other rickettsiae. In conclusion, the three mite species identified here are new records for their host species and for Pakistan. The present findings support that despite the observed genetic differences, C. vespertilionis in southern Asia (Pakistan) and Europe belong to the same species and share common ancestry with C. vespertilionis in east Africa (Kenya). The soft tick species, Argas sp. "rousetti" is most likely a not yet described species within the subgenus Chiropterargas Hoogstraal, 1955, because it was clearly separated from A. boueti Roubaud & Colas-Belcour, 1933 and A. confusus Hoogstraal, 1955 in the phylogenetic analysis (also taking into account that other known species of the subgenus are unlikely to occur in Pakistan). The novel Rickettsia genotype from Argas sp. "rousetti", represents the first molecular identification of a Rickettsia sp. phylogenetically close to R. honei, and the first Rickettsia sp. from any bat-associated soft tick species in southern Asia.

“…The mites of the genus Steatonyssus (Acarina: Parasitiformes: Gamasina: Macronyssidae) are permanent specific parasites of chiropterans. Ecologically they occupy an intermediate position between nest-breeding and transient ectoparasites, which are characterized by a relatively short feeding time on the host and are more dependent on shelters than representatives of such genera as Macronyssus and Spinturnix [44]. In this respect, Steatonyssus spp.…”

Trypanosoma dionisii, for which only bat bugs (Cimicidae) had previously been demonstrated as vectors, was, for the first time, detected in the gamasine mite Steatonyssus periblepharus in Russia. The molecular phylogenetic analysis indicated that trypanosomes found in these mites belong to the “clade A” of T. dionisii, which, based on genetic distances, can be considered as a species separate from the sister clade B, and according to available data also has a distinct geographic distribution. The presence of developmental forms of T. dionisii resembling those previously described during the development of this trypanosome in cimicids suggests that S. periblepharus is a novel vector of the studied trypanosome.
