| [the age-related structure of an ixodes ricinus population studied by using a rapid anatomical method]. | a rapid anatomic method for the assessment of the physiologic age of ticks and their virtual age was used in studies of the age structure of a natural population of i. ricinus in the moscow region. the anatomic method was found quite fit for the purpose. the findings evidence that the age structure of i. ricinus (active imago) population is heterogeneous with variously directed seasonal fluctuations. in spring the structure is the youngest (up to 60% of imagoes are in the second age, 8 months) a ... | 1992 | 1435580 |
| [the identification of borrelia isolated in the soviet union and czechoslovakia from ixodes ricinus (l.) ticks]. | seven strains of the causative agent of lyme borreliosis have been isolated from ticks of the species ixodes ricinus (l.) obtained at the territories of leningrad province, lithuania and czechoslovakia. the strains have been studied in reactions with 5 types of monoclonal antibodies. all isolated strains belong to serotype ii according to barbour's system and are typical for european strains. | 1990 | 2145716 |
| tick-borne borrelioses pathogen identification in ixodes ticks (acarina, ixodidae) collected in st. petersburg and kaliningrad baltic regions of russia. | two isolated baltic seashore populations of ixodes ticks were studied as vectors of different borrelia genospecies in russia by using darkfield microscopy and modified polymerase chain reaction (pcr). in the kalinigrad region (kurish spit, forests near the settlements of lesnoye and rybachy), 788 ixodes ricinus (l.) adults and nymphs were collected by flagging and studied by darkfield microscopy during 1995-1996. there were 88 darkfield microscopy positive specimens (11.2%) of which 69 were also ... | 1998 | 9538573 |
| [the biodiversity dynamics of the causative agents of diseases transmitted by ticks in the genus ixodes: an analysis of multiyear data]. | fauna of pathogen's met in the organism of the primary tick-borne disease vectors--ixodes persulcatus schulze and ixodes ricinus (l.) was observed. prevalence of borrelia mono- and poly-infection in the i. persulcatus ticks within a season of the vector activity was analyzed and increase of the number of the dual infected specimens during the season was demonstrated. the first determination of ehrlichia infected i. ricinus and i. persulcatus collected in the baltic region of russia was stated. t ... | 1999 | 10703200 |
| differences in borrelia infections in adult ixodes persulcatus and ixodes ricinus ticks (acari: ixodidae) in populations of north-western russia. | dark-field microscopy was used to determine the number of borrelia spirochetes in 630 standard preparations obtained from adult ixodid ticks (344 ixodes persulcatus and 286 i. ricinus) collected in 1989-92 in the leningrad region of russia. the average numbers of borrelia in i. persulcatus and i. ricinus preparations were 34.7 and 23.3 per 100 microscopic fields, respectively. the maximal individual values registered each year for ticks of both species were several hundred times greater than the ... | 1995 | 7621710 |
