[experimental infection of ixodid ticks with karshi virus].the ixodid ticks hyalomma asiaticum, h. anatolicum, dermacentor niveus were infected experimentally with karsha virus. the virus replication has been proved to occur in the tick's organism. the titre of the virus grows gradually in infected ticks. entering the tick's gut during its feeding virus particles penetrate into the gut walls where primary multiplication and accumulation of the virus take place.19863024093

genetic variability of crimean-congo haemorrhagic fever virus in russia and central asia.hyalomma marginatum ticks (449 pools, 4787 ticks in total) collected in european russia and dermacentor niveus ticks (100 pools, 1100 ticks in total) collected in kazakhstan were screened by elisa for the presence of crimean-congo haemorrhagic fever virus (cchfv). virus antigen was found in 10.2 and 3.0 % of the pools, respectively. rt-pcr was used to recover partial sequences of the cchfv small (s) genome segment from seven pools of antigen-positive h. marginatum ticks, one pool of d. niveus ti ...200312692285
detection of a rickettsia closely related to rickettsia aeschlimannii, "rickettsia heilongjiangensis," rickettsia sp. strain rpa4, and ehrlichia muris in ticks collected in russia and kazakhstan.using pcr, we screened 411 ticks from four genera collected in russia and kazakhstan for the presence of rickettsiae and ehrlichiae. in russia, we detected "rickettsia heilongjiangensis," rickettsia sp. strain rpa4, and ehrlichia muris. in kazakhstan, we detected rickettsia sp. strain rpa4 and a rickettsia closely related to rickettsia aeschlimannii. these agents should be considered in a differential diagnosis of tick-borne infections in these areas.200415131195
[elisa and rt-pcr-based research of viruses in the ticks collected in the foci of crimean-congo fever in kazakhstan and tajikistan in 2001-2002].different species of ticks were found, in the territories of kazakhstan and tajikistan, to be infected with the virus of crimean-congo hemorrhagic fever (ckhf). the virologic evaluation included determination of antigen and rna of the ckhf virus by elisa and rt-pcr, respectively. the below tick species were found to be involved in the epidemic process: hyalomma asiaticum, dermacentor niveus (kazakhastan) and hyalomma anatolicum (tajikistan). the results testify to the fact that hyalomma ticks ar ...200515747867
tick-borne rickettsioses around the world: emerging diseases challenging old concepts.during most of the 20th century, the epidemiology of tick-borne rickettsioses could be summarized as the occurrence of a single pathogenic rickettsia on each continent. an element of this paradigm suggested that the many other characterized and noncharacterized rickettsiae isolated from ticks were not pathogenic to humans. in this context, it was considered that relatively few tick-borne rickettsiae caused human disease. this concept was modified extensively from 1984 through 2005 by the identif ...200516223955
[genetic monitoring of the crimean-congo hemorrhagic fever virus in kazakhstan and tajikistan in 2001-2003].blood specimens obtained from 32 cchf patients were tested for the presence of cchf virus markers. in addition, 3210 ticks of the genera hyalomma asiaticum, hyalomma anatolicum, and dermacentor niveus were examined to identify the cchf virus antigen and rna. this material was obtained during the 2001-2003 local outbreaks of cchf in kazakhstan and tajikistan. the nucleotide sequence in the region 983-1282 of s segment of the cchf virus for 12 wild type strains was determined. the phylogenetic rel ...200616756002
[determination of tick species and treatment of cows, sheep and goats in the sivas-zara region].the purpose of this study was to examine tick infestation in cattle, sheep and goats in the zara-sivas region for one year and to determine the epizootiology of the tick species as well as to investigate treatment of the infested animals. tick infestation was detected in 71 (29.6%) out of 240 cattle, 66 (24.0%) out of 275 sheep and 50 (19.9%) out of 252 goats in the zara region. it has been shown that the tick infestation on cattle included haemaphysalis parva (33.8%), dermacentor marginatus (2. ...200617160854
status of tick infestation of cattle in the kayseri region of turkey.this study was carried out to determine the status of tick infestation of cattle in the kayseri region in turkey. eight hundred and sixty-six cattle and their barns in 12 localities were examined during the period of june 2000-november 2001, where 188 (21.7%) of which were infested by ticks. a total of 1,585 ticks consisting of rhipicephalus turanicus (2.27%), r. bursa (2.14%), r. sanguineus (0.94%), hyalomma marginatum (17.16%), h. anatolicum excavatum (24.73%), h. a. anatolicum (19.62%), derma ...200717823821
[fine structural features of the sensory system in the ixodid tick dermacentor niveus (parasitiformes, ixodidae)].the main sensory organs (eyes, haller's organ, and palpal organ) of dermacentor niveus were examined in scanning and transmitting electron microscopes. the haller's organ consists of a capsule with five porous sw-wp olfactory sensilla and pleomorphs; anterior pit with porous sw-wp, two grooved dw-wp, two thin np-sw, and one conical dw-np sensilla; four posterior dw-wp sensilla; and anterior group of sw-wp and dw-up sensilla. duct orifices of two dermal glands are situated near the capsule. conta ...200919370977
genetic evidence for conspecificity between dermacentor marginatus and dermacentor niveus.ticks are hematophagous arthropods transmitting several harmful human and animal pathogens like viruses, rickettsia, bacteria, and protozoa. the identification and speciation of ticks were normally performed in iran using identification key of arthur (1960) and kaiser and hoogstraal (j parasitol 49:130-139, 1963) or on the basis of morphological characteristic keys recommended by walker et al. (2003). although these identification keys are well prepared, but there are in some cases due to the st ...200919562378

a broad-range survey of ticks from livestock in northern xinjiang: changes in tick distribution and the isolation of borrelia burgdorferi sensu stricto.borreliosis is highly prevalent in xinjiang uygur autonomous region, china. however, little is known about the presence of borrelia pathogens in tick species in this region, in addition borrelia pathogens have not been isolated from domestic animals.201526337627
update on tick-borne rickettsioses around the world: a geographic approach.tick-borne rickettsioses are caused by obligate intracellular bacteria belonging to the spotted fever group of the genus rickettsia. these zoonoses are among the oldest known vector-borne diseases. however, in the past 25 years, the scope and importance of the recognized tick-associated rickettsial pathogens have increased dramatically, making this complex of diseases an ideal paradigm for the understanding of emerging and reemerging infections. several species of tick-borne rickettsiae that wer ...024092850
first description of the nymph and larva of dermacentor raskemensis (acari: ixodidae), parasites of pikas and other small mammals in central asia.dermacentor raskemensis pomerantzev, 1946 is one of the rare asian species in this genus. the immature stages of this species have never been described. reexamination of d. raskemensis holdings stored in the united states national tick collection revealed a collection lot containing reared nymphs and larvae of this species. this collection made it possible for us to find numerous nymphs and larvae of d. raskemensis among previously unidentified material collected in the field. both immature stag ...024180099
