first records of hyalomma aegyptium (acari: ixodida: ixodidae) from the russian spur-thighed tortoise, testudo graeca nikolskii, with an analysis of tick population dynamics.during the fall of 1995 and the spring of 1996, 77 statistically comparable tick collections, comprising 792 specimens, were made from adults of the russian spur-thighed tortoise, testudo graeca nikolskii, at 4 sites along russia's black sea coast. these are the first tick collections reported from t. g. nikolskii since its recognition as a taxonomic entity. all ticks were determined to be hyalomma (hyalomma) aegyptium, a common tortoise parasite in southern russia that in 1930 was erroneously d ...19989920339
tick species (acari: ixodida) in antalya city, turkey: species diversity and seasonal activity.ticks (acari: ixodida) are an important group of ectoparasites of vertebrates. most species are known vectors of diseases including lyme disease, q fever, and crimean-congo hemorrhagic fever. a 3-year research was conducted in antalya, turkey, to determine tick species composition, seasonal abundance, and spatial distribution. the study was carried out in five districts (aksu, dosemealtı, kepez, konyaaltı, and muratpasa) of antalya metropolitan municipality area in turkey, between may 2010 and m ...201525869959
preferences of different tick species for human hosts in turkey.the ticks removed from the patients who applied to the hospitals in istanbul and neighboring cities, turkey, with the complaint of tick bite were examined in this study, on account of their species, biological stages, attachment sites on the body, and the age of the affected patients. a total of 16,969 ticks were identified. encountered species were as follows: 33.6 % ixodes spp. immature, 25.3 % hyalomma spp. immature, 24.3 % i. ricinus, 9.5 % rhipicephalus sanguineus gr., 3.2 % r. bursa, 2.2 % ...201323620419

ectoparasites of hedgehogs (erinaceus concolor) from turkey.hedgehogs are small, nocturnal, spiny-coated animals that have been growing in popularity as exotic pets. however, these animals are host to a wide variety of viruses, bacteria, fungi and parasites, some of which are of zoonotic character. thus, because hedgehogs have a potential role to transmit zoonoses including arthropod-borne diseases, we examined them for their ectoparasites. the study was carried out on hedgehogs found dead mainly due to road casualties in the bursa province of turkey. th ...201526281445
parasitism of immature stages of haemaphysalis sulcata (acari: ixodidae) on some reptiles in turkey.reptiles may contribute to maintaining tick populations by feeding larvae, nymphs, and adults. the life cycles and tick-host associations of many turkish ticks are still poorly known, and only 3 ixodid tick species have been reported on 7 reptile species in turkey. in this study, we performed a tick survey on reptiles in the southeastern anatolia region of turkey. in 2005, 57 reptiles (52 lizards and 5 snakes) comprising 10 species from 5 families were captured and examined for tick infestation. ...201323560648
assessment of bacterial diversity in hyalomma aegyptium, h. marginatum and h. excavatum ticks through tag-encoded pyrosequencing.ticks are among the most significant human-biting ectoparasites and they play a major role in transmission of many pathogenic agents to humans. in the present study, three species of hyalomma ticks, hyalomma aegyptium, h. marginatum and h. excavatum, were examined for the presence of zoonotic bacteria, both male and female ticks alike. examination of microbial diversity with tag-encoded pyrosequencing indicates that h. marginatum and h. excavatum were more diversity rich than h. aegyptium. altho ...201729124413
the dependence of hyalomma aegyptium on its tortoise host testudo graeca in algeria.hyalomma aegyptium (linnaeus, 1758) (ixodida: ixodidae) has recently been confirmed as a carrier of numerous pathogenic, including zoonotic, agents. four environmentally distinct regions of algeria, located between the humid coastal zone and the arid saharan atlas range, were selected in order to compare differences in tick abundance among localities, and the correlations between tick abundance and host population characteristics and other environmental conditions. sampling was carried out durin ...201627218892
infestation of the spur-thighed tortoise (testudo graeca) by hyalomma aegyptium in tunisia.we examined 210 spur-thighed tortoises (testudo graeca) for the presence of ticks in tunisia during may 2014. a total number of 602 adult ticks were collected and identified leading to the estimation of parasitological indicators. all the ticks belonged to a single species: hyalomma aegyptium. the mean infestation prevalence was 66.2%, mean overall infestation intensity and abundance were 4.33 and 2.86 ticks/tortoise respectively. our survey showed that tortoises were significantly more infested ...201525791981
