Babesia species are important canine pathogens with a nearly worldwide distribution. Our understanding of the distribution of these parasites is continually improving. This is in large part, due to improved molecular diagnostic capabilities. However, it can be difficult to assimilate and compare previous reports from various regions due to differences in molecular methods. In this report, we characterize the results of over 100,000 canine samples from 52 different countries and territories spanning 4 continents that were submitted to a commercial diagnostic laboratory for Babesia testing by polymerase chain reaction. The same diagnostic algorithm was used for all samples and is designed to identify and differentiate B. gibsoni, B. canis, B. vogeli, B. rossi and B. conradae. Overall 3.4% of the samples submitted tested positive for the presence of Babesia sp. DNA and were differentiated to the species level. Babesia gibsoni was the most commonly identified species (48.8% of the positive results) followed by B. canis (35.2%) then B. vogeli (15.3%). Babesia gibsoni and B. vogeli were more widely distributed than B. canis, which was primarily found in Europe. This is the largest study of its type and these data provide a global overview of which Babesia species veterinarians could expect to find in their practice area.
