tick-borne encephalitis virus, zealand, denmark, 2011. 023764123
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
human granulocytic anaplasmosis, japan.we retrospectively confirmed 2 cases of human anaplasma phagocytophilum infection. patient blood samples contained unique p44/msp2 for the pathogen, and antibodies bound to a. phagocytophilum antigens propagated in thp-1 rather than hl60 cells. unless both cell lines are used for serodiagnosis of rickettsiosis-like infections, cases of human granulocytic anaplasmosis could go undetected.023460988
severe fever with thrombocytopenia syndrome virus in ticks collected from humans, south korea, 2013.we investigated the infection rate for severe fever with thrombocytopenia syndrome virus (sftsv) among ticks collected from humans during may-october 2013 in south korea. haemaphysalis longicornis ticks have been considered the sftsv vector. however, we detected the virus in h. longicornis, amblyomma testudinarium, and ixodes nipponensis ticks, indicating additional potential sftsv vectors.025061851
mitochondrial genomes suggest that hexapods and crustaceans are mutually paraphyletic.for over a century the relationships between the four major groups of the phylum arthropoda (chelicerata, crustacea, hexapoda and myriapoda) have been debated. recent molecular evidence has confirmed a close relationship between the crustacea and the hexapoda, and has included the suggestion of a paraphyletic hexapoda. to test this hypothesis we have sequenced the complete or near-complete mitochondrial genomes of three crustaceans (parhyale hawaiensis, squilla mantis and triops longicaudatus), ...016024395

human infections with borrelia miyamotoi, japan.we confirmed infection of 2 patients with borrelia miyamotoi in japan by retrospective surveillance of lyme disease patients and detection of b. miyamotoi dna in serum samples. one patient also showed seroconversion for antibody against recombinant glycerophosphodiester phosphodiesterase of b. miyamotoi. indigenous relapsing fever should be considered a health concern in japan.025061761
whole-genome sequencing of borrelia garinii bgvir, isolated from taiga ticks (ixodes persulcatus).most lyme borreliosis cases in russia result from borrelia garinii nt29 group infection. borrelias of this group circulate exclusively in ixodes persulcatus ticks, which are seldom found beyond russia and the far east. here we report the whole-genome sequence of borrelia garinii bgvir isolated from an i. persulcatus female.023012288
anaplasma phagocytophilum infection in domestic animals in ten provinces/cities of china.a nationwide epidemiologic investigation of domestic animal infections has been conducted in nine provinces and one city during 2007-2010. serum samples from a total of 707 goats, 433 cattle, and 219 dogs were collected for detecting anaplasma phagocytophilum igg antibody by immunofluorescence assays and the average seroprevalences were 10.05% for dogs, 3.82% for goats, and 0.69% for cattle, respectively. a total of 472 goats, 201 cattle, 102 dog blood clots, and 1,580 ticks were collected for p ...022764312
heterogeneity of 3'-untraslated region of genome rna of the tick-borne encephalitis virus (tbev) strains isolated from ticks in the western siberia, russia.the tick-borne encephalitis virus (tbev) strains have been isolated from unfed adult ticks ixodes persulcatus schulze in novosibirsk region (south-western siberia, russia) beginning from 1980 till 2006. the tbev 3'-untraslated region (3'utr) variable fragment was amplified with primers corresponding to conserved flanking areas. the rt-pcr product lengths varied in range from 100 to 400 bp. comparative analysis of 3'utr nucleotide sequences revealed a few groups of the tbev strains within siberia ...023675045

[distance orientation of the tick ixodes persulcatus to the attractant factors of the prey].the laboratory and field tests have shown that the odour is the main factor which activates ticks (ixodes persulcatus) attraction to the host. ticks have a sensation of a man on 15 metres distance; the number of activated ticks increases with the distance to the host and depends on the wind direction. the infrared radiation source excites only a short time activation of the ticks on 0.5-1.0 metres distance. mechanic and sound stimulations were found to be uneffective for the ticks in the experim ...19761018934

[uneven degree of aging of intestinal epithelium of hungry ticks ixodes persulcatus].adult individuals of i. persulcatus are characterized by uneven assimilation of nutrients in digestive cells of the mid-gut. in the mid-gut of females and males exist simultaneously parts with different degrees of exhaustion. physiological age of a hungry individual is determined by three items: "main" physiological age; degrees of exhaustion "accompanying" it; and, in addition, by different degrees of exhaustion of individual digestive cells in the limits of one portion of the mid-gut. calculat ...19761023145
[tarsal gland of ixodid ticks (ixodidae)].in the tarsi of all legs of ixodes persulcatus, dermacentor daghestanicus, rhipicephalus turanicus and hyalomma asiaticum the multicellular gland was observed. the gland is formed by a single layer of glandular cells that form a central cavity where two ciliary structures in a cuticular (scolopoid) sheath are situated. a possible function of the gland is discussed in the article.19761026913
[influence of temperature on the duration of the developmental cycle of ixodes persulcatus (ixodidae) ticks].experiments were conducted with ticks of i. persulcatus collected in the vicinity of khabarovsk. the females were fed at the beginning of june, hatched larvae and nymphs--after the completion of postlarval development. the ticks were maintained in testglasses at constant humidity, at temperatures of 6, 12, 15, 28 and 33c in darkness. minimum developmental periods of the ticks from egg to imago are 211 days at 28c, 732 days at 15c and 869 days at 12c. the development without diapause was not obse ...1977865882
