detection of rickettsia and ehrlichia spp. in ticks associated with exotic reptiles and amphibians imported into japan.one of the major routes of transmission of rickettsial and ehrlichial diseases is via ticks that infest numerous host species, including humans. besides mammals, reptiles and amphibians also carry ticks that may harbor rickettsia and ehrlichia strains that are pathogenic to humans. furthermore, reptiles and amphibians are exempt from quarantine in japan, thus facilitating the entry of parasites and pathogens to the country through import. accordingly, in the current study, we examined the presen ...201526207382
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
systematic revision of the adeleid haemogregarines, with creation of bartazoon n. g., reassignment of hepatozoon argantis garnham, 1954 to hemolivia, and molecular data on hemolivia stellata.life cycles and molecular data for terrestrial haemogregarines are reviewed in this article. collection material was re-examined: hepatozoon argantis garnham, 1954 in argas brumpti was reassigned to hemolivia as hemolivia argantis (garnham, 1954) n. comb.; parasite dna was extracted from a tick crush on smear of an archived slide of hemolivia stellata in amblyomma rotondatum, then the 18s ssrrna gene was amplified by pcr. a systematic revision of the group is proposed, based on biological life c ...201526551414
seroepidemiological studies of crimean-congo hemorrhagic fever virus in domestic and wild animals.crimean-congo hemorrhagic fever (cchf) is a widely distributed, tick-borne viral disease. humans are the only species known to develop illness after cchf virus (cchfv) infection, characterized by a nonspecific febrile illness that can progress to severe, often fatal, hemorrhagic disease. a variety of animals may serve as asymptomatic reservoirs of cchfv in an endemic cycle of transmission. seroepidemiological studies have been instrumental in elucidating cchfv reservoirs and in determining endem ...201626741652
molecular detection and identification of spotted fever group rickettsiae in ticks collected from the west bank, palestinian territories.tick-borne rickettsioses are caused by obligate intracellular bacteria belonging to the spotted fever group (sfg) rickettsiae. although spotted fever is prevalent in the middle east, no reports for the presence of tick-borne pathogens are available or any studies on the epidemiology of this disease in the west bank. we aimed to identify the circulating hard tick vectors and genetically characterize sfg rickettsia species in ixodid ticks from the west bank-palestinian territories.201626771654

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
novel borrelia species detected in echidna ticks, bothriocroton concolor, in australia.to date, little has been documented about microorganisms harboured within australian native ticks or their pathogenic potential. recently, a borrelia sp. related to the relapsing fever (rf) group was identified in a single tick removed from a wild echidna (tachyglossus aculeatus). the present study investigated the presence of borrelia in 97 bothriocroton concolor ticks parasitizing echidnas in queensland, new south wales, and victoria, australia, using nested pcr with borrelia-specific primers ...201627301754
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
