Abstract

We report the presence of Babesia vogeli in dogs in Chile. During two surveillance campaigns separated by a year, sixty-three blood samples from free-ranging rural dogs in Coquimbo, Chile, were analysed through conventional PCR screening of the 18S rRNA for Babesia species. Sequencing confirmed the presence of Babesia vogeli in 6.3% of the tested animals, with positive cases in both years. All the sequences showed 100% nucleotide sequence identity among them and 99.8% with other previously published sequences from dogs. No clinical signs or haematological abnormalities other than thrombocytopenia were found in the parasitized individuals. This is the first report of a canine piroplasmid in Chile.

Keywords: South America; canine; piroplasmid.
