Neosporosis, caused by Neospora caninum, is an important cause of abortion in cattle and of neurological disease in dogs. This study investigated the prevalence and correlates of antibodies to N. caninum in 441 dogs from the five regions of mainland Portugal. A commercial competitive enzyme-linked immunosorbent assay (cELISA) was used and specific antibodies were detected in 35 (7.9%) dogs. Seroprevalence levels were significantly different among some of the studied regions, as well as between stray dogs (13.6%) and hunting dogs (1.7%). The difference between seropositivity in dogs presenting musculoskeletal or neurological signs (21.4%) and that in animals without clinical signs compatible with neosporosis (5.6%) was close to statistical significance. This is the first report on the seroprevalence of N. caninum in dogs in Portugal. Neosporosis should be considered in the differential diagnosis of neurological disorders of dogs.
Résumé
La néosporose, causée par Neospora caninum, est une cause importante d’avortement chez les bovins et de maladie neurologique chez les chiens. Cette étude porte sur la prévalence et les corrélations des anticorps contre N. caninum chez 441 chiens en provenance des cinq régions du Portugal continental. Un test commercial d’immuno-absorption enzymatique par compétition (cELISA) a été utilisé et des anticorps spécifiques ont été détectés dans 35 (7,9 %) des chiens. Les niveaux de séroprévalence étaient significativement différents entre certaines des régions étudiées, ainsi qu’entre les chiens errants (13,6 %) et les chiens de chasse (1,7 %). La différence entre la séropositivité des chiens présentant des signes musculo-squelettiques ou neurologiques (21,4 %) et des animaux sans signes cliniques compatibles avec la néosporose (5,6 %) était proche de la signification statistique. Cette étude est le premier rapport sur la séroprévalence de N. caninum chez les chiens au Portugal. La néosporose doit être considérée dans le diagnostic différentiel de désordres neurologiques des chiens.
