The aim of the present work was to investigate the seroprevalence against Ehrlichia canis (Ec), Anaplasma phagocytophilum (Ap), Neorickettsia risticii (Nr), Rickettsia conorii (Rc), and Borrelia burgdorferi (Bb) in two different clusters of canine samples from Northwestern Spain. Cluster 1. included 479 dogs presented at veterinary clinics located in Ourense and Pontevedra. Cluster II included 170 dogs from the public kennel of Ourense. All 649 canine serum samples were analyzed by immunofluorescent antibody test. Prevalences against the above-mentioned agents in cluster I were: Rc (24.60%), Bb (6.26%), Ec (3.13%), Ap (5.01%), and Nr (1.04%), whereas for cluster II were: Rc (50%), Bb (8.8%), Ec (54.7%), Ap (45.3%), and Nr (4.7%). Rc was significantly associated with age and history of exposure to ticks, and Bb showed a statistical relationship with age and clinical status. Ec and Ap were related to the occupation of the dogs, with stray dogs being the most frequently seropositive. Furthermore, seroreactivity against Ec and Ap was significantly higher in Ourense than in Pontevedra. The univariate analysis demonstrated a significant concomitant seroreactivity between Ec and Ap and between Rc and Ec and Ap antigens. The seroreactivity to Nr must be interpreted very cautiously as this infectious agent has been seldom reported outside North America.
