Cleavage in Ixodes ricinus (L.) (Acari: Ixodidae).
نویسنده
چکیده
The author analyzed the first 5 days of embryonic development of Ixodes ricinus. The cleavage takes 4 days, being terminated on the 5th day of embryogenesis, when the cells start to invaginate and differentiate. The karyomeres play a role in the initial mitotic divisions. Cellularization occurs on the 2nd and 3rd day of embryogenesis. The blastoderm cells maintain their potential for division, and as from the 5th day cellular differentiation starts.

A total of 150 nymphal Ixodes ricinus (L., 1758) (Acari: Ixodidae) from the Czech Republic were examined for Anaplasma phagocytophilum (Foggie, 1949) Dumler et al., 2001 by PCR using EHR521/747 primers: 22 of 50 pools were positive (minimum prevalence, 14.7%). However, sequencing of the PCR products did not show complete homology with A. phagocytophilum (91%) while the closest relationship (95%...

Questing Ixodes ricinus (Acari: Ixodidae) adult and nymphal ticks collected in various parts of Slovenia were tested for the presence of babesial parasites with a PCR assay based on the nuclear small subunit rRNA gene (nss-ribosomal DNA [rDNA]). Thirteen of 135 ticks were found to contain babesial DNA. Sequence determination and analysis of amplified portions of nss-rDNA revealed their identity...

The vector competence of 2 tick species, Ixodes ricinus (L.) and Ixodes scapularis Say, was determined and compared for 3 genospecies of Borrelia burgdorferi. The 3 genospecies of B. burgdorferi used in the following experiments were Borrelia burgdorferi sensu stricto (B-31 and B-31.D1 clone), Borrelia afzelii (strain Pgau. C3), and Borrelia garinii (strain VS286 and VSBP). Spirochetes from all...
متن کاملFactors affecting the geographical distribution of Ixodes ricinus (Acari: Ixodidae) and its transmitted pathogens in Europe
Many biotic and abiotic factors are involved in determining the distribution of the important tick vector Ixodes ricinus (Acari: Ixodidae) in Europe, as well as in driving changes in its occurrence within its prior endemic zones. This paper aims to review some of the main factors that could have affected the geographical distribution of this tick species and its transmitted pathogens in Europe ...

Developmental forms of Babesia spp. were studied in isolated salivary glands of Ixodes ricinus, subjected to the Feulgen reaction. The same ticks were also hosts to Babesia microti, which was determined by PCR amplification with primers specific to the fragment of a gene encoding the nuclear small sub-unit ribosomal RNA (SS-rDNA). Presence of Babesia spp. was recorded in the salivary glands of ...
