Development of a Multilocus Sequence Typing scheme for the study of Anaplasma marginale population structure over space and time
(Elsevier, 2015-03)Bovine Anaplasmosis caused by Anaplasma marginale is a worldwide disease prevalent in tropical and subtropical regions where Rhipicephalus microplus is considered the most significant biological vector. Molecular markers ... -
Diverse tick-borne microorganisms identified in free-living ungulates in Slovakia
(BMC, 2018-09)Background: Free-living ungulates are hosts of ixodid ticks and reservoirs of tick-borne microorganisms in central Europe and many regions around the world. Tissue samples and engorged ticks were obtained from roe deer, ... -
Dynamics of Exposure to Rickettsia parkeri in Cattle in the Paraná River Delta, Argentina
(Oxford Academic Press, 2016-05)Several cases of human rickettsiosis caused by Rickettsia parkeri were recently documented in the Paraná River delta of Argentina, where the tick vector is Amblyomma triste Koch. As cattle suffer recurrent A. triste ... -
Ecology of the interaction between Ixodes loricatus (Acari: Ixodidae) and Akodon azarae (Rodentia: Criceridae)
(2015-10)The present study explores associations of different factors (i.e. host parameters, presence of other ectoparasites and [mainly biotic] environmental factors) with burdens of Ixodes loricatus immature stages in one of its ... -
Factors affecting patterns of Amblyomma triste (Acari: Ixodidae) parasitism in a rodent host
(2015-07-30)Here we offer a multivariable analysis that explores associations of different factors (i.e., environmental, host parameters, presence of other ectoparasites) with the interaction of Amblyomma triste immature stages and ... -
Fiebre manchada en Argentina. Descripción de dos casos clínicos = Spotted fever in Argentina. Description of two clinical cases
