New records of soft ticks (Acari: Argasidae) from caves in Brazil, with a morphological study of Ornithodoros fonsecai and an analysis of the taxonomic status of Antricola inexpectata
(Elsevier, 2024-05)In this study, we report soft ticks from bat-inhabiting caves in different areas of Brazil. From 2010 to 2019, we collected 807 tick specimens from nine caves located in four Brazilian states among two biomes. Ticks were ... -
Niche divergence among closely related taxa provides insight on evolutionary patterns of ticks
(Wiley, 2021-09)Aim: Understanding the degree to which closely related taxa diverge in their niche traits could provide insight on their evolutionary patterns, as well as shed some light on the mechanisms underpinning broad-scale biogeographic ... -
Non-parasitic life cycle of the cattle tick Rhipicephalus (Boophilus) microplus in Panicum maximum pastures in northern Argentina
(2017)The aim of this work was to study the non-parasitic phase of the Rhipicephalus microplus life cycle in Panicum maximum grasses from northern Argentina, in order to provide ecological information for designing methods of ... -
Novel Anaplasma (Rickettsiales: Anaplasmataceae) strain and Hepatozoon sp. cf. H. procyonis (Apicomplexa, Hepatozoidae) detected in Procyon cancrivorus (Carnivora, Procyonidae) from Argentina, with note of tick-host association
(Springer, 2023-04)The aim of this work is to report the first detection of Procyon cancrivorus naturally co-infected with Hepatozoon sp. cf. H. procyonis and a novel Anaplasma strain from South America and potential vector tick species ... -
A novel Ehrlichia strain (Rickettsiales: Anaplasmataceae) detected in Amblyomma triste (Acari: Ixodidae), a tick species of public health importance in the Southern Cone of America
(Taylor & Francis, 2020)The aim of this work was to report the detection of a putative novel Ehrlichia strain associated with the tick Amblyomma triste. Free-living adult ticks determined as A. triste were collected by drag-sampling in Argentina ... -
