| groel typing and phylogeny of anaplasma species in ticks from domestic and wild vertebrates. | anaplasma species are globally distributed tick-borne bacteria causing a range of clinical conditions in domestic animals, wildlife, and human. nevertheless, data on presence and distribution of anaplasma strains in ticks are still lacking, especially in the mediterranean region. this study reports the molecular identification, genetic characterization and phylogeny of anaplasma strains of both veterinary and zoonotic importance in ticks collected from domestic and wild hosts sampled in a typica ... | 2018 | 29089249 |
| tick-host conflict: immunoglobulin e antibodies to tick proteins in patients with anaphylaxis to tick bite. | tick-borne infectious diseases and allergies are a growing problem worldwide. tick bite allergy has been associated with the direct effect of immunoglobulin e (ige) response to tick salivary antigens, or secondary to the induction of allergy to red meat consumption through ige antibodies against the carbohydrate α-gal (gal α 1-3gal β 1-(3)4glcnac-r). however, despite the growing burden of this pathology, the proteins associated with anaphylaxis to tick bite have not been characterized. to addres ... | 2017 | 28423486 |
| genetic characterization of rhipicephalus sanguineus (sensu lato) ticks from dogs in portugal. | the taxonomic status of the brown dog tick rhipicephalus sanguineus (sensu stricto) is a subject of on-going debate; there is a consensus that populations of this tick species should be referred to as r. sanguineus (sensu lato) until its taxonomic status is resolved. recent genetic studies revealed the existence of more than one lineage of r. sanguineus (s.l.) in temperate countries. in this study, we assessed the genetic identity of ticks collected from rural dogs living in several areas locate ... | 2017 | 28285602 |
| comparative analysis of mitochondrial markers from four species of rhipicephalus (acari: ixodidae). | mitochondrial sequences of four mitochondrial markers: 12s rrna, 16s rrna, cytochrome c oxidase subunit i (cox1) and cytochrome b (cytb) from four rhipicephalus species were analyzed to establish genetic relationships and enable molecular identification. field-collected samples from the species rhipicephalus annulatus, rhipicephalus bursa, rhipicephalus sanguineus and rhipicephalus turanicus were amplified by pcr and compared with genbank™ annotated sequences. pcr products were obtained using pr ... | 2013 | 24091196 |
| comparative analyses of mitochondrial and nuclear genetic markers for the molecular identification of rhipicephalus spp. | the genus rhipicephalus (acari: ixodidae) comprises a large number of vectors of pathogens of substantial medical and veterinary concern; however, species identification based solely on morphological features is often challenging. in the present study, genetic distance within selected rhipicephalus species (i.e., rhipicephalus bursa, rhipicephalus guilhoni, rhipicephalus muhsamae, rhipicephalus sanguineus sensu lato and rhipicephalus turanicus), were investigated based on molecular and phylogene ... | 2013 | 24103336 |
