A novel Rickettsia infecting Amblyomma dubitatum ticks in Brazil

Ticks and Tick-borne Diseases, 2011
A total of 130 adult free-living ticks of Amblyomma cajennense and 9 free-living Amblyomma dubitatum were collected in the surroundings of the Pampulha Lake, within Belo Horizonte city, state of Minas Gerais, south-eastern Brazil. Each adult tick was tested for rickettsial infection by PCR protocols targeting the rickettsial genes gltA, htrA, and ompA.

Natural infestation of Hydrochoerus hydrochaeris by Amblyomma dubitatum ticks

Experimental and Applied Acarology, 2014
Natural infestation of Amblyomma dubitatum in relation to individual specific attributes of Hydrochoerus hydrochaeris such as sex, body mass and body condition was analyzed. The anatomical distribution of A. dubitatum on H. hyrochaeris was also evaluated. Prevalence of adults and nymphs were significantly higher than prevalence of larvae.

Hosts, distribution and genetic divergence (16S rDNA) of Amblyomma dubitatum (Acari: Ixodidae)

Experimental and Applied Acarology, 2010
We supply information about hosts and distribution of Amblyomma dubitatum. In addition, we carry out an analysis of genetic divergence among specimens of A. dubitatum from different localities and with respect to other Neotropical Amblyomma species, using sequences of 16S rDNA gene. Although specimens of A.
