Antigens and Alternatives for Control of Anaplasma marginale Infection in Cattle
The recent development of a cell culture system for A. marginale provides a potential source of antigen for the development of improved killed and live vaccines, and the availability of cell culture-derived antigen would eliminate the use of cattle in vaccine production. Expand
Ticks (Ixodidae) on humans in South America
Twenty eight species of Ixodidae have been found on man in South America and ticks of the genus Ixodes do not appear to be major players in transmitting diseases to human. Expand
The Argasidae, Ixodidae and Nuttalliellidae (Acari: Ixodida) of the world: a list of valid species names
This work is intended as a consensus list of valid tick names, following recent revisionary studies, wherein we recognize 896 species of ticks in 3 families. The Nuttalliellidae is monotypic,Expand
Reassessment of the taxonomic status of Amblyomma cajennense () with the description of three new species, Amblyomma tonelliae n. sp., Amblyomma interandinum n. sp. and Amblyomma patinoi n. sp., and
This study provides descriptions and redescriptions, scanning electron microscopic and stereomicroscopic images, updated synonymies, information on geographical distributions, and host associations for each of the 6 species. Expand
An overview of systematics and evolution of ticks.
The origin of ticks is during the pre-mid Cretaceous period (with both the Argasidae and Ixodidae being established in the middleCretaceous). Expand
Mitochondrial DNA analysis of Rhipicephalus sanguineus sensu lato (Acari: Ixodidae) in the Southern Cone of South America.
According with the genetic comparative analysis, NT lineage and the ticks from Mozambique and South Africa represent a species that is not R. sanguineus s.l, and further investigations are needed in order to verify a possible different vectorial competence for the other pathogens transmitted by these ticks. Expand
Biological and DNA evidence of two dissimilar populations of the Rhipicephalus sanguineus tick group (Acari: Ixodidae) in South America.
Differences between these strains are greater than previously assumed and that the biosystematic status of R. sanguineus ticks from South America should be re-evaluated. Expand
Ticks collected on birds in the state of São Paulo, Brazil
The results showed that Passeriformes seems to be primary hosts for subadult stages of A. longirostre whereas ground-feeding passerine birds seem to be the most important for both A. calcaratum and A. nodosum. Expand
The taxonomic status of Rhipicephalus sanguineus (Latreille, 1806).
It is suggested that as a result it is not possible to assign the specific name R. sanguineus s.s. to any population, and further work is required based on the rules issued by the International Code of Zoological Nomenclature to clearly define the morphological range of the different populations.
