Abstract
In this study, the prevalence of piroplasms in dogs was assessed using polymerase chain reaction (PCR) to identify Babesia and Theileria species in 200 dogs from Northern and Central Tunisia between spring and autumn 2014. The overall molecular prevalence for piroplasms was 14·5% ± 0·05 (29/200); PCR detected 2 species, namely Babesia vogeli and Theileria annulata with an overall prevalence of 12·5 ± 0·04 and 2% ± 0·02, respectively. No differences in the molecular prevalences of B. vogeli were revealed for age and sex (P > 0·05). The molecular prevalence of B. vogeli was significantly higher in central Tunisia (26·5% ± 0·01) compared with the North (9·6% ± 0·04) (P 0·05). Comparison of the partial sequences of 18S rRNA and Tams 1 genes confirmed the presence of 2 novel B. vogeli and T. annulata genotypes. This is the first molecular detection of T. annulata and genetic characterization of dogs' piroplasms in Tunisia. Further studies are needed to better assess the epidemiological feature of piroplasms infection in North Africa.
