Resumen: Vector-borne diseases represent a major health challenge, both because of the complexity of their control, their common zoonotic nature, or the pathology they can cause in the individual. In tropical areas, surveillance of these diseases is even more important, since the activity of vectors is usually continuous throughout the year. To develop effective prophylaxis and surveillance programs, it is important to know the identity and prevalence of these pathogens as well as their distribution in a given territory. In Guadeloupe, a French archipelago located in the Lesser Antilles of the Caribbean, no information exists about vector-borne diseases in companion animals. With this aim, blood samples were obtained from 46 owned dogs with outdoor access from five different veterinary clinics located in the two mainland islands, and the presence of DNA of the main canine vector-borne pathogens (CVBP) was investigated through diverse PCR protocols. At least one pathogen was detected in 30.4 % of the dogs. The most frequently detected CVBP was Coxiella burnetii (17.4 %), followed by Dirofilaria immitis (8.7 %), and Candidatus Mycoplasma haematoparvum, Hepatozoon canis and Rickettsia spp. (2.2 % in all cases). One dog was coinfected with Candidatus M. haematoparvum and D. immitis. All samples were negative for Anaplasma spp., Ehrlichia spp., Bartonella spp., Borrelia burgdorferi sensu lato, piroplasmids, and Leishmania spp. No significant differences in pathogen occurrence were observed between the two main islands or according to the dog's sex and age groups. This study contributes to filling a relevant gap in the knowledge of vector-borne diseases in the Caribbean.
