(AOSIS OpenJournals, 2017-01-23)Several nucleic acid-based assays have been developed for detecting Anaplasma marginale and Anaplasma centrale in vectors and hosts, making the choice of method to use in endemic areas difficult. We evaluated the ability ...

Penzhorn, Barend Louis; Vorster, Ilse; Redecker, Gernot; Oosthuizen, Marinda C. (AOSIS OpenJournals, 2016-10)Although there is evidence of high seroprevalence of antibodies to Babesia spp. in dogs in central Namibia, clinical babesiosis is rarely diagnosed. Rhipicephalus sanguineus sensu lato, the vector of Babesia vogeli, is ...
