A community approach to the Neotropical ticks-hosts interactions
(Springer Nature, 2020-06-09)The relationships between ticks and hosts are relevant to capture the ecological background driving the evolution of these parasites. We used a set of 4,764 records of ticks of the genera Amblyomma, Ixodes, and Haemaphysalis ... -
Description of Ornithodoros montensis n. sp. (Acari, Ixodida: Argasidae), a parasite of the toad Rhinella arenarum (Amphibia, Anura: Bufonidae) in the Monte Desert of Argentina
(Springer, 2019-05)A new tick species of the genus Ornithodoros (Acari: Argasidae) was described from larvae collected on the toad Rhinella arenarum in a locality from Argentina belonging to the Monte Biogeographic Province. Ornithodoros ... -
Different lines of evidence used to delimit species in ticks : a study of the South American populations of Amblyomma parvum (Acari: Ixodidae)
(2016-10)The goal of this work was to combine different lines of evidence besides that of molecular markers to delimit species in ticks when the molecular data are not totally congruent. Two groups (Argentina, Brazil) of South ... -
Exploring the ecological and evolutionary relationships between Rickettsia and hard ticks in the Neotropical region
(Elsevier, 2021-06)This study addresses a meta-analysis of the distribution of Rickettsia spp. in the Neotropical region, as well as their associations with ticks and vertebrates. A total of 219 published reports on Rickettsia in ticks in ... -
Genetic analysis of Rhipicephalus sanguineus sensu lato ticks, parasites of dogs in the Canary Islands, Cyprus, and Croatia, based on mitochondrial 16S rRNA gene sequences
(Springer, 2019-03)The aim of this work was to perform an analysis based on mtDNA sequences of the 16S rRNA gene in order to determine the phylogenetic position of ticks belonging to the Rhipicephalus sanguineus group from the Canary Islands, ... -
High prevalence of “Candidatus Rickettsia amblyommii” in Amblyomma ticks from a Spotted Fever Endemic Region in North Argentina
(2016)Ticks from an endemic Spotted Fever region in Argentina were analysed by PCR for Spotted Fever Group Rickettsiae. DNA of “Candidatus Rickettsia amblyommii” was found in 21.3% of Amblyomma hadanii and in 44.0% of A. neumanni. ... -
Ixodes schulzei Aragão & Fonseca, 1951 in Argentina
