Abstract
Forty-five tick species have been recorded in Kazakhstan. However, their genetic diversity and evolutionary relationships, particularly when compared to ticks in neighbouring countries, remain unclear. In the present study, 148 mitochondrial cytochrome c oxidase subunit I (COI) sequence data from our laboratory and NCBI (National Center for Biotechnology Information; https://www.ncbi.nlm.nih.gov/ ) data were used to address this knowledge gap. Phylogenetic analyses showed that i) Hyalomma anatolicum anatolicum (Koch, 1844) ticks from Jambyl Oblast (southeastern Kazakhstan) and Gansu Province (northwestern China) constituted a newly deviated clade; and ii) Dermacentor reticulatus (Fabricius, 1974) ticks from South Kazakhstan Oblast were closer to those in Romania and Turkey. The network diagram of haplotypes showed that i) the H-1 and H-2 haplotypes of Dermacentor marginatus (Sulzer, 1776) ticks from Zhetisu and Almaty were all newly evolved; and ii) the H-3 haplotypes of Haemaphysalis erinacei (Pavesi, 1884) from Almaty Oblast and Xinjiang Uygur Autonomous Region (northwestern China) were evolved from the H-1 haplotype from Italy. In the future, more COI data from different tick species, especially from Kazakhstan and neighbouring countries, should be employed in the field of tick DNA barcoding.

Abstract
Members of the subgenus Eschatocephalus Frauenfeld, 1853 are highly specialized cave-dwelling ectoparasites of bats. We conducted a comprehensive field-based survey on bat ticks in Turkey and provided information about the phylogenetic placement of collected species. Sampling was carried out at 26 caves from 18 provinces around Turkey between 2019 and 2021. Eighty-one tick specimens collected from the cave environment or on various cave roosting bats resulted in five species: Ixodes vespertilionis, Ixodes simplex, Ixodes ariadnae, Ixodes kaiseri, and Haemaphysalis erinacei. While I. simplex was the most frequently collected species with a rate of 56.2% mainly from bats (Miniopterus schreibersii), I. vespertilionis was the most prevalent species (65.4%) and found mainly on cave walls. The first record of I. ariadnae was provided for Turkey. Phylogenetic trees were built using mt 16S rDNA and COI markers. Our results demonstrated the presence of two distinct lineages of I. vespertilionis in Turkey; one lineage grouped with European isolates, whereas three sequences clustered separately. The phylogenetic pattern of I. simplex was consistent with previous results; this clade was clustered distantly to other bat tick species. The significance of the surprising records of H. erinacei and I. kaiseri in caves is also discussed.

Description of a novel Babesia sp. genotype from a naturally infected Eurasian lynx (Lynx lynx) in Anatolia, Turkey, with remarks on its morphology and phylogenetic relation to other piroplasmid species. Ticks Tick Borne Dis 2022; 13:102026. [PMID: 35985208 DOI: 10.1016/j.ttbdis.2022.102026] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2021] [Revised: 07/18/2022] [Accepted: 08/08/2022] [Indexed: 11/16/2022]
Abstract
There are very limited data on Babesia species infecting lynx species worldwide, and almost nothing is known about babesias in the Eurasian lynx, the most widely distributed wild feline species in the Palearctic geography. This study describes a novel Babesia sp. genotype in a free-living Eurasian lynx in Turkey, named tentatively as 'Babesia sp. lynx', and its integrated genetic and morphological features. Phylogenetic analyses of piroplasmids with the novel Babesia sp. genotype in the current study indicated that this genotype falls into the 'carnivore clade A' of Babesia sensu stricto (true babesias), at the level of different genes (mainly 18S rRNA, ITS1, ITS2, and cyt b) and is monophyletic with the Babesia sp. Ankara genotype, previously observed in Turkey. Additionally, the constructed phylogenetic trees showed that the Babesia sp. lynx genotype infecting the Eurasian lynx is closely related to certain domestic and wild carnivore babesias, mainly Babesia rossi, Babesia presentii, and Babesia pisicii, at the level of different genes. This study also genetically barcoded the lynx infected with the Babesia sp. lynx and Haemaphysalis erinacei, and specimens collected from the animal revealed significant genetic variations between the sample Ha. erinacei and Babesia sp. Ankara-related Ha. erinacei that persists with sympatric populations in Central Anatolia. The lynx infected with the Babesia sp. lynx genotype was also found to be coinfected with Hepatozoon felis, an adeleorinid tick-borne protozoan parasite infecting wild and domestic felids, confirming for the first time its presence in a lynx species. Therefore, this study is the first to describe a potential novel Babesia sp. using its both morphological and phylogenetic characteristics in a lynx species. Adding the Babesia sp. lynx genotype to the phylogeny of feline piroplasmids significantly expands our knowledge of feline babesias in the Palearctic geography and their putative coevolution with their vertebrate hosts.

Automatic barcode gap discovery reveals diverse clades of Rhipicephalus spp. and Haemaphysalis spp. ticks from small mammals in 'Asir, Saudi Arabia. Parasit Vectors 2021; 14:541. [PMID: 34666829 PMCID: PMC8527726 DOI: 10.1186/s13071-021-05049-x] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2021] [Accepted: 10/01/2021] [Indexed: 01/14/2023] Open
Abstract
Background The ixodid tick genera Rhipicephalus and Haemaphysalis contain several species of medical and/or veterinary importance, but their diversity in some regions of the world remains under-explored. For instance, very few modern studies have been performed on the taxonomy of these genera on the Arabian Peninsula. Methods In this study, we trapped small mammals in the 'Asir Mountains of south-western Saudi Arabia and collected tick specimens for morphological examination and molecular barcoding, targeting three mitochondrial loci: cox1, 16S rRNA and 12S rRNA. Results We obtained a total of 733 ticks (608 Haemaphysalis spp. and 125 Rhipicephalus spp.) from 75 small mammal hosts belonging to six species. All tick specimens were immature except for nine adults recovered from a hedgehog (Paraechinus aethiopicus). Morphologically, the Rhipicephalus ticks resembled R. camicasi, but the Haemaphysalis ticks showed differences in palp morphology compared with species previously described from Saudi Arabia. Phylogenetic analysis and automatic barcode gap discovery identified a novel clade of Rhipicephalus sp. representing most of the nymphs. This was most closely related to R. leporis, R. guilhoni and R. linnaei. The adult ticks and a small proportion of nymphs clustered with R. camicasi sequences from a previous study. Finally, the Haemaphysalis nymphs formed two distinct clades that were clearly separated from all reference sequences but closest to some African species. Conclusions This apparent high level of tick diversity observed in a single study site of only ~ 170 km2, on a relatively small number of hosts, highlights the potential for the discovery of new tick species on the Arabian Peninsula.

A molecular phylogenetic investigation of tick species in Eastern and Southeastern Anatolia. Ticks Tick Borne Dis 2021; 12:101777. [PMID: 34371304 DOI: 10.1016/j.ttbdis.2021.101777] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2021] [Revised: 05/12/2021] [Accepted: 06/12/2021] [Indexed: 11/22/2022]
Abstract
Understanding the local tick species composition is crucial for overcoming the diseases they transmit. A comprehensive survey integrating molecular identification was conducted in the eastern and southeastern parts of Turkey, where tick surveys have previously been neglected. A total of 596 specimens belonging to four tick genera were collected from 27 localities in Turkey during the summers of 2019 and 2020. Seventy-seven representative individuals were chosen for molecular analysis. Nine distinct species, Rhipicephalus bursa, Rhipicephalus turanicus, Rhipicephalus rossicus, Hyalomma asiaticum, Hyalomma excavatum, Hyalomma marginatum, Hyalomma aegyptium, Haemaphysalis sulcata, and Dermacentor marginatus were identified. The presence of R. rossicus was demonstrated for the first time in Turkey. Two lineages of R. turanicus were identified, and representatives of both lineages were recorded. Our Hyalomma phylogenetic tree was consistent with previous findings from Turkey; however, new sympatric areas for Hy. marginatum and Hy. excavatum and Hy. marginatum and Hy. asiaticum were recorded. Two haplotypes (Haemaphysalis sp. and Dermacentor sp.) could not be identified using morphological and molecular methods. In addition to making a valuable contribution to the molecular database of ticks in the Middle East, this study will also stimulate comparative studies on the genetic structure, ecology, and vector competence of different populations of these species in Turkey as well as in other parts of the world.

Five ixodid tick species including two morphotypes of Rhipicephalus turanicus on nestlings of Eurasian eagle owl (Bubo bubo) from south-eastern Bulgaria. Parasit Vectors 2021; 14:334. [PMID: 34174951 PMCID: PMC8235848 DOI: 10.1186/s13071-021-04832-0] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2020] [Accepted: 06/09/2021] [Indexed: 11/22/2022] Open
Abstract
Background Birds are major hosts for many tick species (Acari: Ixodidae, Argasidae), and their role is especially important in transporting ticks over large distances along their seasonal migratory routes. Accordingly, most studies across Europe focus on the importance of avian hosts in tick dispersal, and less emphasis is laid on resident birds and their role in supporting tick life cycles. Eurasian eagle owls (Bubo bubo) exemplify the latter, but all the few studies on their tick infestation were carried out in Western Europe and even those did not involve a large sample size and did not assess infestation prevalence in natural habitats. Methods In this study, 320 ixodid ticks were collected from nestlings of Eurasian eagle owls during the period 2018–2020 in Bulgaria in south-eastern Europe. These ticks were analysed morphologically, and selected specimens molecularly based on cytochrome c oxidase subunit I (cox1) gene. The effects of environmental and habitat-related conditions and of the species of prey eaten by eagle owls on tick infestation were also evaluated. Results The majority of ticks were identified as adults of Rhipicephalus turanicus (n = 296). In addition, 15 Hyalomma marginatum (three males, 11 nymphs and a larva), one female of Haemaphysalis erinacei and of Ha. punctata, and a nymph of Ixodes ricinus were found. Among R. turanicus, two distinct morphotypes were observed, but they do not form a monophyletic clade in the phylogenetic tree based on the mitochondrial gene cox1. We found a positive correlation between the total number of ticks on nestlings from a particular nest and the number of medium-sized to large prey mammals brought to the nestling owls. Also, the most important predictor for tick abundance was the effect of the extent of arable land (negative), while forests and grasslands contributed less, with no effect observed in case of urbanized areas and watercourses. Conclusions The intensity of tick infestation can be high on nestling Eurasian eagle owls (mean intensity 16.59 ticks/nestling). In this study, five different tick species were recorded, among which R. turanicus dominated. Two male morphotypes of this tick species were found, but their morphological differences were not reflected by genetic diversity or phylogenetic clustering. The most important factor determining tick abundance was the land-use structure. Graphic Abstract ![]()

Abstract
Arthropod vectors have historically been identified morphologically, and more recently using molecular biology methods. However, both of these methods are time-consuming and require specific expertise and equipment. Matrix-assisted laser desorption ionization time-of-flight mass spectrometry, which has revolutionized the routine identification of microorganisms in clinical microbiology laboratories, was recently successfully applied to the identification of arthropod vectors. Since then, the robustness of this identification technique has been confirmed, extended to a large panel of arthropod vectors, and assessed for detecting blood feeding behavior and identifying the infection status in regard to certain pathogenic agents. In this study, we summarize the state-of-the-art of matrix-assisted laser desorption ionization time-of-flight mass spectrometry applied to the identification of arthropod vectors (ticks, mosquitoes, phlebotomine sand-flies, fleas, triatomines, lice and Culicoides), their trophic preferences and their ability to discriminate between infection statuses.

First records and molecular-phylogenetic analyses of three tick species (Ixodes kaiseri, Hyalomma lusitanicum and Ornithodoros coniceps) from Malta. Ticks Tick Borne Dis 2020; 11:101379. [PMID: 32001157 DOI: 10.1016/j.ttbdis.2020.101379] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2019] [Revised: 01/09/2020] [Accepted: 01/19/2020] [Indexed: 10/25/2022]
Abstract
The Maltese islands are situated south of mainland Europe and north of Africa, therefore are expected to share tick species and tick-borne pathogens with both continents. This situation highlights the importance of studying ticks in this country. Nevertheless, the tick fauna of Malta appears to be a seldom investigated issue, with hitherto only five tick species reported in the country. Here, as part of a tick collection campaign continuing since 2016 in Malta, three tick species new to the country are reported and analyzed in comparison with GenBank data. Ixodes kaiseri (collected from North African hedgehog in Malta) had unique cytochrome c oxidase subunit I (cox1) and 16S rRNA gene haplotypes (with 98.1-99.3 % sequence identity to I. kaiseri from Europe and China). Phylogenetically, these haplotypes from Malta clustered separately from other, mainland-associated haplotypes, with high support. On the other hand, Ornithodoros coniceps (collected from domestic chicken in Malta) had identical or nearly identical cox1 and 16S rRNA gene haplotypes with soft ticks reported from France, northern Africa and western African islands, similarly to Hyalomma lusitanicum (collected from rabbit and cat in Malta) in comparison with conspecific ticks in Spain and Portugal. These results are most likely related to differences in host associations and corresponding translocality of these three tick species. Taken together, results of the present study add three new tick species to those five already known to be present in Malta.

Abstract
Ticks are important vectors of emerging and re-emerging pathogens. The aim of this study was to determine tick species occurring in Xinjiang Uygur Autonomous Region (XUAR), especially on border regions. A total of 22,994 ticks (including 22,629 adults, 365 larvae and nymphs), belonging to six tick genera (i.e. Dermacentor, Hyalomma, Rhipicephalus, Haemaphysalis, Ixodes and Argas) and fourteen tick species, were collected from ten animal hosts in thirty-five counties (cities) in XUAR during 2011 - 2017. Rhipicephalus turanicus, Dermacentor niveus, Hyalomma asiaticum and Dermacentor marginatus were dominantly sampled from domestic animals while Dermacentor nuttalli, Haemaphysalis punctata, Haemaphysalis concinna, Rhipicephalus sanguineus sensu lato, Dermacentor silvarum, Hyalomma scupense and Argas persicus were sporadically found. Based on 16S rDNA, phylogenetic analyses showed that: i) R. turanicus genotypes in XUAR showed geographical separation, and belonged to clade I (major distribution in the Central Asian) rather than clade II (major distribution in the Mediterranean Basin); ii) Ixodes kaiseri, firstly sampled from Asian badgers (Meles leucurus), was in ancestral position compared to European tick species when combining COI haplotypes; and iii) Haemaphysalis erinacei from marbled polecats in China was a separate genotype compared with that in Mediterranean and Europe. Our findings suggest that geographical range plays a more important role than host-association in tick phylogeny, especially for R. turanicus, I. kaiseri and H. erinacei.

Abstract
Since ancient times, philosophers and taxonomists have tried to classify forms of life. This is what taxonomy is about: the science of identifying, naming, classifying, and describing organisms. In this article I address the issue of the species concept in tick taxonomy. While the typological species concept is still the most widely used, the biological and phylogenetic species concepts are growing in popularity among tick taxonomists. The integrative approach is increasingly being used, but the question is how to define a tick species when using this approach, particularly if data are incongruent. The adoption of an integrative species concept is discussed, in light of recent advances in our understanding of the genetics, morphology, and biology of ticks.

Abstract
Background Many tick species have great morphological similarity and are thus grouped into species complexes. Molecular methods are therefore useful in the classification and identification of ticks. However, little is known about the genetic diversity of hard ticks in China, especially at the subspecies level. Tengchong is one of the epidemic foci of tick-borne diseases in China, but the tick species inhabiting the local area are still unknown. Methods Eighteen villages in Tengchong County, China, were selected for sampling carried out from September to October 2014. Infesting hard ticks were removed from the body surface of domestic animals and questing ticks were collected from grazing fields. After morphological identification, molecular characteristics of each tick species were analyzed based on both 16S rRNA and cytochrome c oxidase subunit 1 (cox1) gene fragments. Results Six tick species were identified based on morphology: Rhipicephalus microplus, R. haemaphysaloides, Ixodes ovatus, Haemaphysalis longicornis, H. shimoga and H. kitaokai. Phylogenetic analysis using the cox1 gene revealed that R. microplus ticks from the present study belong to clade C. For tick samples of both R. haemaphysaloides and I. ovatus, three phylogenetic groups were recognized, and the intergroup genetic distances exceeded the usual tick species boundaries. Haemaphysalis longicornis ticks were clustered into two separate clades based on the cox1 gene. For ticks from both H. shimoga and H. kitaokai, two phylogenetic groups were recognized based on the phylogenetic analysis of the 16S rRNA gene, and the intergroup genetic distances also exceeded the known boundaries for closely related tick species. Conclusions According to molecular analyses, new species or subspecies closely related to R. haemaphysaloides, I. ovatus, H. shimoga and H. kitaokai probably exist in the China-Myanmar border Tengchong County, or these ticks form species complexes with highly divergent mitochondrial lineages. Morphological comparisons are warranted to further confirm the taxonomic status of these tick species.

EXPERIMENTAL & APPLIED ACAROLOGY 2017; 73:493-499.

Abstract
Rhipicephalus turanicus is an important tick species potentially carrying tick-borne pathogens. Several tick species have obvious subspecies divergence. However few studies aimed to examine the existence of divergence within R. turanicus. Therefore, a detailed morphological and molecular analysis was conducted for comparing R. turanicus from the Mediterranean Basin (represented by Albania) and Central Asia (Northwestern China). Altogether 315 adult ticks of R. turanicus (103 from Albania and 212 from China) were morphologically and molecularly analysed. DNA samples were used for mitochondrial 16S rRNA and cox1 gene sequences analysis. In addition, as potentially genetic markers, three fragments including partial nad1-16S rRNA, nad2-cox1, cox1-tRNA-Lys, were designed and then phylogenetically analyzed. Based on detailed morphological observations, only basis capituli length:width ratio (females), the length, the width and the length:width ratio of the scutum (males) had differences between R. turanicus from China and Albania. Gene divergences of 16S rRNA, cox1, partial nad1-16S rRNA, nad2-cox1 and cox1-tRNA-Lys from China and Albania ticks were 3.53-4.84, 3.57-4.92, 3.57-4.07, 3.57-4.39 and 3.18-4.69%, respectively. The evaluated five genetic markers revealed two phylogenetic branches in R. turanicus. Obvious differences exist within R. turanicus based on morphological and genetic analysis. Three newly designed genetic markers (partial nad1-16S rRNA, nad2-cox1 and cox1-tRNA-Lys) in this study may be suitable genetic tools for identification and analysis in R. turanicus. Subspecies analysis of R. turanicus from other regions of the world should be initiated in the future.

Flaisz B, Sulyok KM, Kováts D, Kontschán J, Csörgő T, Csipak Á, Gyuranecz M, Hornok S. Babesia genotypes in Haemaphysalis concinna collected from birds in Hungary reflect phylogeographic connections with Siberia and the Far East. Ticks Tick Borne Dis 2017; 8:666-670. [PMID: 28499722 DOI: 10.1016/j.ttbdis.2017.04.013] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2017] [Revised: 03/31/2017] [Accepted: 04/09/2017] [Indexed: 12/25/2022]
Abstract
Haemaphysalis concinna is the second most common tick species attaching to birds in Hungary. Recently, Babesia genotypes, found in Siberia and the Far East, have been detected in this tick species collected from the vegetation in Hungary and Slovakia. The aim of this study was to molecularly investigate if these piroplasms also occur in H. concinna carried by migratory birds, which might explain their occurrence in the western Palaearctic. During a 2-year period, 321 H. concinna larvae and nymphs were collected from 121 passerine birds (of 19 species) in Hungary. These were molecularly investigated for the presence of piroplasm DNA with PCR and sequencing. The prevalence of PCR positive ticks was 15.9% (51 out of 321). Piroplasm PCR positivity of H. concinna ticks was significantly more frequent during the summer and autumn compared to spring, suggesting that migratory birds arriving in Hungary from the north or north east are the most important in the dispersal of H. concinna-associated piroplasms. Three genotypes, i.e. Babesia sp. "Irk-Hc133", "Irk-Hc130" (originally found in Irkutsk, Siberia) and "Kh-Hc222" (originally found in Khabarovsk, Far East) were detected. Phylogenetically all these belonged to the group formed by Babesia spp. of ruminants. Four bird species, which had 14-60% prevalence of PCR positive ticks, are known to be associated with northeast to southwest autumn migration. In conclusion, the presence of Central and East Asian Babesia genotypes in Central Europe are most likely related to bird species with known eastern migratory habit and/or phylogenetically substantiated connections between their eastern and western Eurasian populations.
